ABSTRACT
A multi-unit pilot plant of significant scale was used to study the
biological treatment of integrated kraft pulp and paper wastewaters after
conventional primary clarification. The biological units in the project
included two high-rate trickling filters packed with PVC media, an oxida-
tion ditch with brush-type aeration, and an earthen lagoon with mechanical
surface aeration.
Many alternates were possible because the main feed could be excluded
from one or more biological units and, in its place, any of the pilot unit
effluents except the aerated lagoon could be pumped back to the main weir
box for feed. Simultaneous series and parallel operation of the four
biological systems was thus possible. The combinations using normal
strength wastewater included:
a) Trickling filters in series
b) Trickling filter to aerated lagoon
c) Oxidation ditch to aerated lagoon
d) Oxidation ditch to trickling filter.
Black liquor was added to the clarified effluent on a continuous basis for
a limited period of time in order to elevate the BOD level from approxi-
mately 200 mg/1 to approximately 500 mg/1 and the following combinations
were tested:
a) Trickling filter to oxidation ditch to trickling filter
b) Trickling filter to aerated lagoon
c) Trickling filters in series followed by oxidation ditch.
Best efficiencies at normal effluent strength were obtained on the pilot
oxidation ditch when run with clarification and sludge return as the ex-
tended aeration process. BOD,, removals as high as 94 percent were possible.
The trickling filter with sludge recycle performed slightly better than the
conventional trickling filter. BOD,, removals of 60 to 70 percent were
possible.
The conventional aerated lagoon at short detention times was improved by
clarification of the treated effluent. BOD removals of 80 percent were
possible.
Much information is presented on the pilot unit performances; many of the
data have been mathematically modeled. Also presented are results from
support studies which included nutrient testing, velocities within the
aeration basins and many others.
This report is submitted in fulfillment of Grant No. WPRD-55 (12040 EMY)
between the Federal Water Quality Administration and The Mead Corporation.

SECTION I SUMMARY" OF RESULTS AND CONCLUSIONS
The most significant findings of this project pertain to reductions of
biochemical oxygen demand (BOD) in the kraft pulp and paper mill effluent
which was studied. This same effluent was dosed to a higher BOD level
in several test series for a comparison with treatment of normal strength
effluent. The BOD reductions which were accomplished by trickling fil-
tration, the aerated lagoon, and the oxidation ditch process both in
parallel operation and in combinations will be presented in this SUMMARY.
Additional detail and results from support studies are presented in
subsequent SECTIONS and may be used for other conclusions in answer to
specific questions or situations.
Trickling Filter Treatment of Kraft Effluent After Primary Clarification
The high-rate plastic-media trickling filter with 1:1 recycle and nutrient
addition is shown to be capable of consistently removing 60 to 70 percent
of the applied BOD at hydraulic loading rates up to 4000 gallons per day
per square foot and organic loading rates as high as 140 pounds of BOD
per day per 1000 cubic feet of media volume at temperatures generally
above 25°C. Additional detail on test conditions and loading rates are
found in SECTION IV of this report.
With nutrient addition but no recycle, the removal efficiency drops to
less than 50 percent at similar and higher loading rates.
The recycle of sludge back to the trickling filter does not adversely
affect the treatment operation and may provide a satisfactory method for
significantly reducing the excess sludge which must be handled after
biological treatment. In addition, significantly less nutrients are con-
sumed when sludge is recycled. No advantage was taken of this finding
during this project.
Aerated Lagoon Treatment of Kraft Effluent After Primary Clarification
The conventional aerated lagoon with nutrient addition and without second-
ary clarification is shown to produce a variable treatment efficiency
ranging from 35 to 80 percent for detention times of 1.5 to 3.8 days at
temperatures ranging from 16 to 30°C. Test conditions and loading rates
are detailed in SECTION V of this report.
Secondary clarification of these same aerated lagoon effluents is shown
to produce a fairly consistent treatment efficiency at or above 80 percent
BOD removal.
Oxidation Ditch Treatment of Kraft Effluent After Primary Clarification
The oxidation ditch with nutrient addition when operated as an extended
aeration process (i.e., with clarification and total sludge return) is
shown to produce high treatment efficiencies. At one-day detention,
-------
treatment efficiencies ranged from 68 to 86 percent BOD removal. At
two-day detention, the efficiencies ranged from 80 to as high as 94 per-
cent. Temperatures ranged from 16 to 30°C. Test conditions and loading
rates are detailed in SECTION VI of this report.
Since excess sludge was not wasted on a routine basis, such operation of
the oxidation ditch may provide a satisfactory method for significantly
reducing the problems of secondary sludge disposal which do occur with
other high-efficiency biological systems. Nutrient consumption with such
operation was the lowest of any system studied in this project.
Combination Treatment of Kraft Effluent After Primary Clarification
Five different combinations of the biological treatment processes were
tested in 7 separate tests. The test conditions and loading rates are
detailed in SECTION VII of this report. The following general results
were found.
A roughing trickling filter preceding the conventional aerated lagoon
improves the overall BOD,, removal by 5 percent over that obtained by the
aerated lagoon alone.
A polishing trickling filter following the oxidation ditch process im-
proves the overall BOD,, removal by less than one percent over that
obtained by the oxidation ditch process alone.
The two trickling filters in series improve the overall BOD removal by
20 percent on the average over that obtained by a single trickling filter.
The aerated lagoon was not able to reduce the BOD concentration fed from
the oxidation ditch process although some improvement should result if
the final lagoon is allowed to reach equilibrium. The need for aeration
in such a lagoon is doubted.
Treatment of Black Liquor-Dosed Kraft Effluent
The regular kraft effluent from the primary clarifier was dosed with black
liquor to produce BOD. levels above 500 mg/1 contrasted to 200 mg/1 in
the regular effluent used in the previous tests. A total of 3 individual
tests and 5 combination tests were run with the following findings.
The high-rate plastic-media trickling filter with filtrate recycle is
shown to be capable of removing 42 percent of the applied BOD at an
organic loading of 620 pounds of BOD- per day per 1000 cubic reet of media.
With no recycle, the removal efficiency on the black liquor-dosed feed
drops to less than 15 percent at an organic loading of 1070 pounds of BOD,.
per day per 1000 cubic feet.
-------
The conventional aerated lagoon without secondary clarification is shown
to produce a treatment efficiency of 81 percent for a detention time of
7 days at a temperature of 23°C. Clarification of this effluent does not
significantly improve the treatment efficiency as was the case at shorter
detention times. The carryover of solids in the lagoon effluent is
therefore seen to be a function of detention time in the lagoon.
A roughing trickling filter preceding the conventional aerated lagoon
improves the overall BOD,, removal by 6 percent over that obtained by the
aerated lagoon alone at 1.8 days detention.
A single roughing trickling filter preceding the oxidation ditch process
does not significantly improve the overall BOD removal over that obtained
by the oxidation ditch process alone.
A polishing trickling filter following the roughing trickling filter-
oxidation ditch combination does not further improve the BOD removal.
Two trickling filters in series preceding the oxidation ditch process do
improve the overall BOD,, removal by 14 percent over that obtained by the
oxidation ditch process alone.
The two trickling filters in series improve the overall BOD removal by
14 percent over that obtained by the first trickling filter alone.
Chemical and Power Needs for Treatment
Nitrogen and phosphorus are required as nutrients to achieve the BOD re-
ductions detailed above. Using bulk prices for ammonia and phosphoric
acid nutrient sources, the average chemical cost at 100:5:1 BOD:N:P feed
ratio is approximately 0.4 cents per pound of applied BOD,.. A lower
nutrient feed rate should be adequate but was not attempted in this
project, SECTION VIII of this report details the measured consumption
rate of nutrients in each of the biological treatment units for each
test series.
Power consumption of the turbine and brush type surface aerators is a
function of aerator submergence. SECTION VIII also details the net power
input per 1000 gallons of aeration basin capacity and the resulting
degree of mixing and the BOD,, removal rates at various power inputs.
Best Treatment Results
TABLE 1 (page xiii) contains a summary of the best treatment results
obtainable during this project. Each test is identified by unit
process abbreviation as follows:
-------
TF1 for Trickling Filter with Sludge Recycle
TF2 for Trickling Filter with Filtrate Recycle
AL for Aerated Lagoon
OD for Oxidation Ditch
CL2 for Clarifier 2 normally used with OD
The test number follows the unit process so that OD-8 means Oxidation
Ditch Test Number 8; or TF2-1 means Test Number 1 on Trickling Filter
with Filtrate Recycle.
This symbolism is being introduced now for the benefit of the reader who
may venture beyond the RECOMMENDATIONS of this report to learn the actual
test conditions and study the detailed test results.

SECTION II RECOMMENDATIONS
Recommended Use of Project Results
Utilization of the many findings of this project could be difficult with-
out a guide of some type. Therefore the following guide is offered:
1. The relative efficiencies found in the work of this project for the
several treatment processes under study should hold for any given efflu-
ent having characteristics similar to the effluent used in this project.
2. All absolute findings on BOD removal pertain to the treatment of a
specific integrated kraft pulp and paper effluent after primary clarifi-
cation or this same effluent after being dosed to a higher BOD
concentration by the addition of kraft black liquor.
3. The removal of BOD,, when black liquor was not being added can be pre-
dicted for the project wastewater by any of the specific treatment unit
models contained in TABLE 2 (pagexvi). The "constraints" and "range of
values" are basic to these models and must be obeyed if the "constants"
are to be meaningful.
4. For the similar treatment of effluents different from the project
wastewater for which the models were developed, similar mathematical forms
only with different constants would be expected. These constants would
have to be developed on each specific wastewater by methods such as de-
tailed by Eckenfelder and Ford (9).
5. The removal of BOD when black liquor was being added cannot be pre-
dicted by the models in TABLE 2. Treatment of the project wastewater as
dosed would have to be predicted on a comparative basis using those results
actually obtained and which are presented in later SECTIONS of this report.
6. The removal of BOD by combinations of the treatment processes in this
project cannot be predicted by the models in TABLE 2. Rather, the same
comparative basis with actual results would be necessary.
7. Those findings which pertain to mixing, basin hydraulics, and other
support studies not dependent upon the effluent character are applicable
to similar situations at other locations (see SECTION VIII).
Recommended Future Work
The general area of nutrient addition rates for biological treatment should
be studied with the objective of controlling these rates to optimum levels.
Further work should also be directed toward determining the extent to
which the high efficiencies of the oxidation ditch process shown in this
project could be accomplished in a short-term aerated lagoon with clari-
fication and sludge return. Such a system, if found possible, could use
existing or modified treatment facilities to enable high efficiencies at
greatly reduced land requirements.

INTRODUCTION
Biological Treatment of Kraft Mill Efflue_nts_
The sulfate or "kraft" process now dominates the chemical pulping field.
A total of 113 kraft mills in operation in the United States in 1969 pro-
duced 78 percent of all chemical pulp (13).
The kraft pulping process utilizes a cooking liquor mixture of sodium
hydroxide, carbonate, sulfide, and sulfate (19) which allows a strong pulp
to be produced from almost any wood species. The waste liquor can be put
through a furnace for recovery of the sodium and sulfur compounds for
material reuse and production of heat from the wood pulping waste products.
Such a recovery process significantly reduces the potential for stream
pollution. These factors make the kraft pulping process practical,
economical and, therefore, widespread.
The National Council of the Paper Industry for Air and Stream Improvement
has reviewed the status of effluent treatment in the U. S. segment of the
industry and reports the following (13):
1. Approximately 49 percent of the U. S. kraft mills provide secondary
treatment of some type.
2. 47 percent of these mills have installed storage oxidation basins
(26 mills with 36 percent of total treated flow).
3. 31 percent have installed aerated stabilization basins (17 mills
with 39 percent of total treated flow).
4. 16 percent have installed activated sludge (9 mills with 20 percent
of total treated flow).
5. Less than 4 percent have trickling filters (2 mills with 2 percent
of total treated flow).
6. One mill with 2.5 percent of the total treated flow has employed
other means of secondary treatment.
It is concluded that secondary treatment in the kraft pulping industry
means biological treatment of some type rather than chemical treatment.
Whether this tendency changes in the future remains to be seen. However,
the biodegradable characteristics of these process effluents do favor
biological treatment.
-------
Project Purpose and Need
The overall project objectives as stated in the revised application are:
1. To determine effect of influent solids and organics on biological
process treatment efficiencies.
2. To evaluate potential of plastic trickling filters as:
a. Main process for biological treatment
b. Roughing filters prior to conventional aerated lagoons
c. Roughing filters prior to and polishing filters after
oxidation ditch utilizing the brush-type aerator.
3. To evaluate role of secondary clarification and sludge return in
conjunction with biological methods described above.
4. To evaluate combinations of the methods of treatment discussed above
in providing higher levels of organic and solids removals than are
conventionally obtained. BOD removals up to 90 percent should be
possible.
The need for such a project was brought about by the rising requirements
for effluent treatment efficiency coupled with the fact that activated
sludge processes, while capable of producing these high efficiencies, are
also plagued with such undesirable traits as susceptibility to shock
loads, close supervision requirements and high capital and operating costs.
This project was directed toward studying the capabilities of other
biological treatment processes, both singularly and in combination, in an
attempt to find a satisfactory substitute for the expensive and difficult-
to-operate conventional activated sludge process.
Award of Grant to The Mead Corporation
The need for such a project was outlined by The Mead Corporation to the
Federal Water Quality Administration (FWQA, but previously FWPCA) in late
1966. Under the Water Quality Act of 1965 and the amendment by the Clean
Water Restoration Act of 1966, Federal funds were made available for the
first time to private companies and industries for research and demon-
stration programs designed to reduce the problems of water pollution.
This project was granted in late 1966. The design and construction of
the pilot plant were completed in early 1968. The actual field testing
for the project was conducted in 4 phases spanning June 1968 to May 1970.
Three progress reports have already been submitted (1)(2)(3). The present
report is the final report of the project and will present all findings to
date, including those previously contained in the three progress reports.

SECTION IV
THE PILOT PROJECT
The Pilot Plant
FIGURE 1 (page 10) is an overall view of the pilot plant system as con-
structed and FIGURE 2 (page 11) is a schematic diagram showing the
individual units which will be described below.
Pilot Trickling Filters (TF1 and TF2)
The trickling filters were two columns of plastic-type media in three
8-foot sections supported independently on a 4-story steel beam structure.
Access stairs and walkways, media storage, flow splitting boxes and piping
for other systems were also supported by this structure.
Each trickling filter media column was 24 feet high with a surface area
of 16 square feet. The media was Koroseal Vinyl Pack (PVC) supplied by
B. F. Goodrich. Each pack was 2 feet by 2 feet by 4 feet and weighed
34 pounds.
Trickling Filter 2 (TF2) was run at a media height of 16 feet for two
tests, and Trickling Filter 1 (TF1) at 22 feet for two tests. All other
tests were conducted at 24 feet due to the difficulty encountered in
removing the growth-laden media.
The Trickling Filters were run in parallel and series, as roughing and
polishing filters for the oxidation ditch, and as a roughing filter ahead
of the aerated lagoon for a total of 18 separate tests on each filter.
TF1 recycled sludge, while TF2 recycled filter effluent in the conven-
tional manner.
Recycle rates from 0:1 to 5:1 (recycle to feed) were tested on TF1. On
TF2, rates of 0:1 to 2:1 were utilized. Hydraulic loadings as high as
8000 gallons per day per square foot were applied to TF1, while 6000
gpd/sf was the maximum applied to TF2.
TF2 was run ahead of the Rex clarifier during the initial stage of the
project. Later, when this clarifier was used with the oxidation ditch,
the filter effluent samples were settled in the laboratory as simulation
of field clarification.
The two Trickling Filters as constructed were each a complete system and
did not depend upon any other unit for independent operation except for
the flow splitting box and main feed pumps.

Pilot Aerated Lagoon Unit (AL)
The Aerated Lagoon (AL) was a square earthen basin with rounded corners
and sloping sides lined with 20 mil polyvinyl chloride (PVC). It had a
steel truss bridge for walkway and support for the 3 horsepower turbine
aerator supplied by Mixing Equipment Company. The aerator had a diameter
of 29 inches and operated at 84 revolutions per minute.
The depth (and corresponding surface area and volume) was varied from
5 feet to 7.7 feet by means of an adjustable overflow dam. The volume
increased from 88,500 gallons at 5 feet depth to 162,300 gallons at
7.7 feet depth.
Detention time was varied from 1.4 to 7.0 days by means of the flow
splitting weir box provided.
Aerator power consumption was monitored by a 3-phase wattmeter. Power
consumption was varied by adjusting submergence of the turbine at the
aerator shaft or varying overflow height at the dam.
Lagoon velocities, flow direction and bottom sludge were monitored from
the bridge using special equipment as discussed in PROCEDURES.
The lagoon was operated in series four times, once behind Trickling
Filter 1, once behind Trickling Filter 2, and twice behind the Oxidation
Ditch. In an additional nine tests, the lagoon was operated parallel
to the other pilot units.
The lagoon was constructed as a complete system and did not depend on
any other unit for its operation except the flow splitting box and main
feed pumps.
Pilot Oxidation Ditch Unit (OD)
The Oxidation Ditch (OD) was an elongated oval basin with vertical sides
of reinforced concrete and rounded ends of steel plate. A center column
supported the flow baffles, mid feather and steel walkway. Massive
concrete pillars supported the brush-type aerator. The major portion
of construction was above ground, due to space limitations.
The OD unit was 11 feet high with a maximum liquid depth of 10 feet.
Each foot of depth equalled 22,500 gallons volume. The surface area
was a constant 3,005 square feet.
The 10 horsepower massive rotor aerator was supplied by Beloit Passavant.
This brush-type aerator had a width of 66 inches and operated at 65 revo-
lutions per minute.
12
-------
The ditch depth (and corresponding volume) was varied from 4 feet to
8.6 feet by means of a standpipe and a unique flexible joint embedded in
the bottom. Detention time was varied from 1 to 3 days utilizing the
flow splitting weir box.
The ditch contents were overflowed in the channel downstream from the
brush aerator. The feed was added in the channel upstream of the aerator.
Either of the two functions could have been handled upstream of or down-
stream from the aerator.
Velocities and bottom sludge were monitored in the channel upstream,
downstream and opposite the aerator, as discussed later.
Aerator power consumption was monitored by a 3-phase wattmeter. Brush
submergence was kept constant during the project by utilizing the stand-
pipe for adjustment.
In 8 tests the ditch was operated as an extended aeration activated sludge
unit with sludge return from the Rex secondary clarifier. This sludge
was added just upstream of the aerator close to the regular feed point.
During part of these tests the ditch was run in series ahead of or behind
the trickling filters and ahead of the aerated lagoon. The remaining two
tests were without sludge return as in the aerated lagoon process.
The OD as constructed, was a complete system, and did not depend upon any
other unit for its independent operation except for the flow splitting
box and main feed pumps.
Pilot Clarifier Units (Clarifier 1 and Clarifier 2)
The clarifiers used were a rim flow with sludge arm, and a center feed
with a cone bottom and center mixing. Both were of steel plate con-
struction.
The rim flow unit (Clarifier 2) was 12 feet in diameter overall, with
11 feet comprising the settling zone. The height was 11.5 feet, giving
a settling zone of 8150 gallons and a detention time greater than one
hour for high design flows. The cone bottom unit (Clarifier 1) had a
15-foot overall diameter with a depth of 11.5 feet for a total volume of
9900 gallons. This volume represented three zones; mixing zone of
4975 gallons, settling zone of 3635 gallons, and a sludge zone of 1290
gallons.
The Rim Flow, Tow Bro Clarifier mechanism was supplied by Rex Chain Belt.
The Rex unit was used with Trickling Filter 2 and the Oxidation Ditch.
The cone bottom unit was used with Trickling Filter 1 exclusively.
The sludge withdrawal rate was varied as required by means of the unique
pumping and piping system. Sludge was pumped back into the respective
systems or wasted if necessary.
13
-------
Pumps for Pilot System
Two main feed pumps and six smaller process pumps permitted the return of
virtually any treated or untreated effluent to any pilot treatment system.
Many independent and dependent flow systems were provided. The pumps were
supplied by Goulds and Yeoman. The piping was plastic, PVC and black iron,
while all valves were cast iron.
Electrical Power for Pilot System
550 volt, 3-phase electricity was supplied to the pilot site control
center. Separate breakers and switches were provided for each of the two
main feed pumps, each of the six process pumps, the Rex clarifier mechan-
ism, the Mixco aerator and the Beloit brush. A transformer reduced the
voltage to 110-220 volts for pilot area lighting, control center lighting
and receptacles, and sampling station receptacles at each pilot unit.
Pilot Scale
The pilot systems for this project were built large enough to minimize the
effect of pilot to full scale data extrapolation. Flow rates to the Trick-
ling Filters ranged from 11 to 67 gpm (16,000 to 96,500 gpd). For the
Aerated Lagoon, the flow rate was varied from 16 to 80 gpm (23,000 to
115,200 gpd). The Oxidation Ditch influent rates were varied from 31 to
109 gpm (45,000 to 157,000 gpd).
Project Plans
A total of 59 separate tests were run on the pilot units between June 10,
1968 and May 1, 1970. Each Trickling Filter had 18 separate tests, the
Aerated Lagoon was tested 13 times, and the Oxidation Ditch had 10 tests
completed.
TABLE 3 (page 12)shows the completed project plans for all systems with the
independent variables identified and the test settings given.

Presentation of Data
All data were reviewed and edited with respect to validity of the indi-
vidual BOD results and unusually large variation in the characteristics
of the pilot unit feed. These edited data were then averaged over that
time believed to represent acclimation at the test conditions. This
acclimation period was taken consecutively and always included the last
week of test results except where temperature or feed BOD extremes
deviated greatly from previous weeks. Data results and analysis will be
presented in subsequent SECTIONS of this report.
General Aspects of Mathematical Modeling
The term mathematical modeling as it applies to biological systems is the
derivation of a mathematical expression which defines the treatment
efficiency or effluent concentration to be anticipated from a particular
biological system. It relates the various parameters which bear influence
upon the anticipated removal or effluent. In general, a given biological
system and its performance will be a function of the effluent being
treated, the makeup of the biomass which is accomplishing this treatment,
and other parameters such as detention time, temperature, and certain
reaction rate constants. These constants take into account the relation
between the particular effluent being treated and the biological system
accomplishing this treatment.
Mathematical models may be expected to take one of several general forms.
In the first, the BOD removal is a function of the influent BOD concen-
tration, the detention time, the biological mass, temperature, and a
reaction rate constant which is a combination of constants defining cer-
tain aspects of the biokinetics of the system as well as the susceptibility
of the effluent being treated to these biokinetic processes. The second
form is where the BOD remaining is a function of the detention time (the
time of exposure), temperature, influent waste concentration and a reaction
rate constant. The establishment of the particular relationship can be
done through purely mathematical approaches or through certain graphical
relationships. The latter method was used during the mathematical model-
ing of the data in this project.
It has been shown (9) that the mathematical model for completely mixed
aerobic systems such as might be expected from the oxidation ditch process
or the aerated lagoon generally takes the following form:
S - S
-V-*-* tk
S v
e
Previous work on trickling filters indicates a retardant form as
follows (9):
15
-------
• = exp [-kAvt]
o
The terms in the above equations are defined as follows:
S is the influent BOD concentration to the treatment unit (mg/1).
S is the effluent BOD concentration from the treatment unit (mg/1).
k is the biological rate constant.
X is the volatile suspended solids under contact in the system and
v is intended as an expression of the active biological mass (mg/1).
t is the detention time of the system (days).
A is the specific area of the filter media (sf/cf).
The influent and effluent concentrations in the above equations are gen-
erally expressed by filtered BOD values. However, the data to be reported
here are based upon unfiltered but settled BOD values. It is anticipated
that the resultant models will reflect this difference.
T-20
The term 6 can be inserted in the above equations as the temperature
correction which must be applied to the reaction rate constant k, where:
6 is the temperature coefficient.
T is the temperature (°C) of the biological process.
The value of 0 then represents the rate at which the activity or biological
rate constant is expected to change with temperature. The magnitude of
this change will be dependent upon the type of system which exists. The
more dispersed the discrete biological particles are, the more susceptible
they can be expected to be to temperature variations because these tem-
perature variations will influence the particular organism and its
individual biokinetics. In the case of large flocculant particles, the
temperature influence along biokinetic lines is secondary and the control-
ling influence is that of the diffusion or transfer of oxygen into the
agglomerated floe particle. The large flocculant growth is less temperature
dependent than the dispersed growth.
Therefore, for a well flocculating system, a low 6 value might well be
expected. For a dispersed system which could occur with extremely low or
high food to microorganism (F/M) ratios, a reasonably large temperature
rate constant could be expected to result. The biological reaction rate
constant k may also be expected to change with feed type and composition
as shown by Tishler (18).
The various mathematical models and the constants associated with them
are presented in the following SECTIONS pertaining to the respective
16
-------
biological systems. In addition to presenting the mathematical formula
and the related constants, the observed effluent BOD concentrations and
overall treatment efficiencies will be compared to those which would be
predicted by the resultant models.

SECTION V
THE PILOT PLANT FEED SOURCE
Location
This project involved the study of biological treatment on particular
effluents from the integrated kraft pulping, bleaching, and papermaking
operation of The Mead Corporation in Chillicothe, Ohio. This Mead manu-
facturing facility consists of a 600-ton per day hardwood kraft pulp
mill with bleach plant and 15 papermachines with a total average pro-
duction of more than 900 tons per day of fine papers.
Raw Water Characteristics
The main water supply of the Chillicothe Division is wells. Some water
is also furnished by a well-point system and a surface water source.
Better than half of the raw water is passed through sand filters and
chlorinated. This filtered water goes to the turbine rooms and part is
used as process water. The rest of the raw water is softened with lime.
A portion is treated with alum and activated silica for certain paper-
making uses. The remainder is used in the bleach plant and the pulp mill.
The untreated water has the following average characteristics:
Total hardness
Calcium hardness
Total alkalinity (MO)
Iron concentration
367 mg/1 (as CaC03>
245 mg/1 (as CaC03>
258 mg/1 (as CaC03)
2.1 mg/1 (as Fe)
The softened water has the following average characteristics:
Total hardness
Calcium hardness
Total alkalinity (MO)

Character of Pilot Plant Feed
167 mg/1 (as CaC03)
64 mg/1 (as CaCO )
65 mg/1 (as CaCO )
27 mg/1 (as CaC03)
Process effluents from the Chillicothe Division are provided primary
clarification and then secondary treatment in an aerated lagoon.
The main pilot plant feed source was mill primary clarifier effluent
(called Pilot Feed or PF). During the course of the project, varying
quantities of bleach plant effluent were being added either to the full
21
-------
scale system by the Chillicothe Division or at the pilot site using a
special pump to maintain a definite ratio. This bleach plant effluent
comes from chlorine-caustic extract-hypochlorite-chlorine dioxide bleach-
ing stages which are generally abbreviated as the CEHD bleaching sequence.
Nutrients were added at the pilot site to maintain a level of 100:5:1
BOD to ammonia as nitrogen to phosphate as phosphorus. Variation of
nutrient concentrations in the mill clarifier effluent are presented in
SECTION VIII and summarized in TABLE 30 (page 105), also in that SECTION.
Four distinctly different Pilot Feeds can therefore be identified during
the course of the project as shown in TABLE 4 (page 15). These categories
will be identified by symbol in the later SECTIONS of this report.
The variation of physical and chemical characteristics is not detailed
here but rather will be shown for each test period on each pilot unit.

SECTION VI
TRICKLING FILTER TREATMENT
The Trickling Filter Process
The trickling filter is the most common method being employed today for
biological treatment of municipal wastewaters. For industrial waste-
waters, however, the situation is different. Only two such treatment
plants are operating in the kraft industry.
Biological filtration as occurs in a trickling filter is not a filtering
or straining process as the name may imply. Rather it is a technique for
promoting contact between the wastewater and an active growth of micro-
organisms which adhere to the filter media. The trickling filter is,
therefore, a fixed bed reactor for biological treatment as opposed to the
activated sludge process which constitutes a fluid bed reactor. More
complete descriptions of the process may be found in the literature
(5)(9)(12).
Many different types of media have been tried through the long history of
trickling filters, but crushed stone or rock is considered by many to be
the most acceptable material. However, within the last 10 to 15 years,
plastic media have received increasing attention because of its ability
to be constructed in tall columns and to be loaded at higher hydraulic
and organic rates, all of which results in less land area required for
treatment.
Standard-rate rock-media trickling filters are normally designed for load-
ings of 25 to 100 gallons per day per square foot of surface area (gpd/sf)
and 5 to 25 pounds of BOD per day per 1000 cubic feet of media volume
(ppd/1000 cf)(5). Trickling filters loaded at rates greater than the
standard rates would be termed high-rate trickling filters. If a filter
receives a BOD loading of over 100 ppd/1000 cf, then it is referred to as
a roughing filter. The acceptable design loading capabilities of
plastic-media trickling filters would place these filters in the high-
rate category.
High-rate plastic-media trickling filters are more applicable for use in
treatment of large volume industrial wastewaters than are conventional
rock-media trickling filters because of resulting space and equipment re-
quirements. This project was involved with operating two 24-foot pilot
trickling filter towers packed with PVC-type plastic media. What follows
is a summary of all results and an analysis of the high-rate trickling
filter as the main process for biological treatment of kraft mill efflu-
ents. The results of combination treatment studies involving the trick-
ling filters and either the oxidation ditch treatment process or the
aerated lagoon treatment process will be presented in SECTION VII of
this report.

Project Results on Pilot Trickling Filter 1
Pilot Trickling Filter 1 (TF1) was unique in that the filter recycle was
sludge underflow from the cone-bottomed clarifier which followed TF1. A
mixing ring in the center of the clarifier was kept agitated, also by re-
turned sludge, as it was fed the filter effluent. Oxygen was transferred
to the wastewater in the trickling filter tower and remained as dissolved
oxygen (D.O.) when the filter effluent contacted the sludge in the mixing
ring. Although actual D.O. levels in this mixing ring averaged above
0.1 mg/1 for most test series, D.O. readings of zero were encountered on
occasion, which means aerobic biological activity would have been hin-
dered in this mixing ring.
Clarification was accomplished outside the mixing ring with the settled
sludge pumped from the cone bottom for recycle to the top of the filter
and to the mixing ring. The volatile solids content of this recycled
sludge varied from less than 0.1 percent to greater than 0.7 percent based
on average test results during tests TF1-8 through 18 of the project.
Earlier testing on this sludge was restricted to volumetric settleable
solids which were found to range up to 950 ml per liter per 30 minutes
(ml/1/30 minutes). A program of wasting of 50 to 100 gallons per day of
this sludge was initiated in test TF1-9 by necessity since the pump, cone
bottom, and distribution pan were all found to clog on occasion and inter-
rupt the treatment operation on TF1. (See TABLE 41 in the APPENDIX
(page 13l) for details of the sludge wasting program on TF1.)
TF1 was constructed with sludge recycle in an attempt to oxidize the ex-
cess sludge that occurs from filter sloughing and also to derive benefit,
if possible, from maintaining active sludge in contact with aerated
trickling filter effluent.
A total of 18 pilot tests were conducted on TF1 during the project. Of
these tests, 17 involved the cone-bottomed clarifier with sludge return
to the mixing ring and sludge recycle to the top of the filter. The re-
sults of these 17 tests will be considered together. The remaining test
(TF1-16) will be handled with Pilot Trickling Filter 2 results.
TF1 test conditions have been arrayed with respect to recycle ratio and
hydraulic loading rate. The edited test results on BOD efficiency of
all tests are shown in this format in TABLE 5 (page 28). Detailed
explanation of this TABLE may be useful since the format is used again.
In TABLE 5, each test period occupies a single row and the tests are not
in numerical order because the results have been arrayed as stated above.
To aid in interpretation, the whole first row will be identified. The
test is shown as TF1-7 which means test period 7 on Trickling Filter 1.
The test conditions for TF1-7 were: 0:1 recycle to feed ratio, which
means no recycle to the top of the filter (1:1 recycle means equal amounts
of recycle and feed applied to the top of the filter); 1330 gallons per
day per square foot hydraulic loading including the recycle volume, if
any; 22 feet of media packed in Trickling Filter 2 for this test; system
26
-------
feed of PF(2) which was mill clarified effluent with partial bleach plant
effluent in actual ratio of 5:1 according to TABLE 4 (page 15); and the
organic loading rate counting only the influent BOD,, strength was 90
pounds of BOD per day per 1000 cubic feet of filter media volume. The
edited test results for these conditions in TF1-7 were: an average
temperature in TF1 effluent of 21°C; the BOD^ removal efficiency of this
unit in this test averaged 51.6 percent. (No overall removal is given
because TF1 was not fed from another of the pilot units. Note that in
Test TF1-17, an overall removal of 82.6 percent is given because the
system feed was OD(BL) which means the Oxidation Ditch during the black
liquor studies had already removed the great majority of total BOD , but
the OD followed by TF1-17 removed a total of 82.6 percent.) The last
column for TF1-7 shows the settled effluent from TF1 to still contain
105 mg/1 BOD- after treatment. Similar or self-explanatory headings for
test results are used on subsequent TABLES which contain exactly the
same format for test conditions.
The change in wastewater solids content across TF1 is summarized for all
tests in TABLE 6 (page 29). Changes in apparent color, pH, ammonia-
nitrogen, and phosphate-phosphorus are summarized in TABLE 7 (page 30).
Individual test averages of all parameters for each test are included for
future reference in TABLES 42 through 59 in the APPENDIX (starting with
page 133).
TF1 test conditions were also arrayed with respect to organic loading
rate and selected parameters from the edited test results have been
plotted in FIGURES 3, 4, and 5 (pages 34, 35, and 36). (TF1 results are
identified by a 1 preceding the test number). These TABLES and FIGURES
are referenced in the following discussion.
BOD,. Removal Efficiency Across TF1
For the 9 tests in which the feed for TF1 was mill clarified effluent
(designated pilot feed or PF) and the recycle ratio was 1:1, the BOD
removal efficiency tended to drop as organic loading increased. Temper-
ature and BOD strength of the influent appeared to influence the effi-
ciencies as seen in FIGURE 3.
Efficiencies at the 1:1 recycle ratio ranged from 42 percent (organic
loading of 250 ppd/1000 cf and hydraulic loading of 8000 gpd/sf) to
almost 80 percent (70 ppd/1000 cf and 2000 gpd/sf). Three other tests
resulted in efficiencies of 60 to 70 percent BOD removal.
The same general downward trend with increasing organic loading is
evident when the recycle to the top of the filter was zero. (See TF1
tests in FIGURE 4.) Sludge was still being recycled to the mixing ring
for agitation during these and all other tests except TF1-16. In the
three tests with zero recycle to the top, the BOD efficiencies ranged
from approximately 36 percent (590 ppd/1000 cf and 6000 gpd/sf) up to
about 51 percent (90 ppd/1000 cf and 1330 gpd/sf).
27
-------
FIGURE 5 shows results when the recycle rate on TF1 was 0.5:1 in two
tests and 5:1, the highest recycle run, in a third test. Removal
efficiencies showed a reverse trend at the 0.5:1 rates. The values were
37 percent (190 ppd/1000 cf and 4000 gpd/sf) and 48 percent (300 ppd/
1000 cf and 6000 gpd/sf). The 5:1 recycle ratio gave an average BOD
removal of 73 percent (90 ppd/1000 cf and 8000 gpd/sf).
All of these data have been mathematically modeled. The results will be
presented at the end of this SECTION.
Solids Removal Across TF1
TABLE 6 presents the average changes in solids across TF1 during the
various tests. Negative signs in this TABLE denote an increase rather than
a decrease in the particular form of solids through the treatment unit.
Total solids decreased in 13 of the 17 pilot tests shown for TF1. This
decrease was generally between 6 and 15 percent. Overall extremes were
58.8 percent increase to 43.2 percent decrease. Except for extremes, the
volatile total solids tended to decrease approximately twice as much as
the total solids. Actual concentrations can be compared in the APPENDIX
TABLES.
The suspended solids portion of the total solids decreased in 14 of the
17 pilot tests. The three increases were quite substantial and were
apparently associated with stabilized solids going over the clarifier
weir since the associated BOD level did not respond with similar in-
creases. The reduction of suspended solids was generally between 14 and
40 percent except for the extremes. The volatile fraction of the sus-
pended solids was seen to decrease at a slightly lesser extent than the
suspended solids.
Generally it appears that reductions in total and suspended solids do
occur across the TFl-clarifier system even though much biological and
inert sludge is being kept in the system for varying periods of time.
The upsets that do occur are infrequent but significant.
Apparent Color, pH, and Nutrient Changes Across TF1
The apparent color always decreased across TF1 as shown in TABLE 7.
"Apparent color" must be distinguished from "true color" which has had the
solids removed and the pH adjusted to 7.6 (see PROCEDURES). The decrease
in apparent color ranged from 3 percent to as high as 52 percent but was
most often between 20 and 30 percent. Treated effluent apparent color
levels were generally in the 1000 to 1700 unit range. When black liquor
was present, the levels doubled.
28
-------
The TF1 process appeared to cause pH changes which always brought the
effluent to an average level of 7.2 to 7.7 even when the average pH in
the feed varied from this range by as much as 0.9 pH units. The presence
of black liquor during the last two test periods meant the feed pH was
generally higher. The resultant effluent from TF1 was in the range of
pH 8.1 to 8.7.
TF1 was found to be a good consumer of ammonia nitrogen and phosphate
phosphorus in 13 of the pilot tests. The fate of the ammonia which was
frequently reduced by 50 percent or more is not accounted for in nitrifi-
cation since little if any increase in nitrates was noted over the pilot
feed source. Close to 30 percent of the influent phosphate was removed
during treatment by TF1. Its ultimate fate may have rested with the
solids which coated the trickling filter media. Other information on
nutrient levels is included in SECTION VIII of this report.
Project Results on Pilot Trickling Filter 2
Pilot Trickling Filter 2 (TF2) was of conventional design as the filter
recycle was trickling filter effluent before clarification. TF2 was
identical to TF1 except for a collection pan instead of the special
clarifier which was under TF1. A conventional design such as TF2 would
normally require a separate clarifier if the trickling filter was not to
be followed by any other treatment process.
Clarification was provided by using Clarifier 2 during the first 3 tests
on TF2. Later tests required that TF2 effluent be settled in the labora-
tory before BOD analysis for clarifier simulation since Clarifier 2 had
to be used in conjunction with the pilot oxidation ditch.
A total of 18 pilot tests were conducted on TF2 during the project. An
additional test from TF1 can be added to these results since the special
clarifier was eliminated in test TF1-16 and the two filters were run in a
similar manner for comparative purposes. The results of all 19 tests
will therefore be considered together.
TF2 test conditions (with test TF1-16 included) have been arrayed with
respect to recycle ratio and hydraulic loading rate. The edited test
results on BOD,, efficiency of these tests are shown within the arrayed
format in TABLE 8 (page 31) . The effect of settling is shown but will not
be plotted. The change in wastewater solids content across TF2 without
clarification is shown in TABLE 9.(page 32). Other changes also without
clarification are summarized in TABLE 10 (page 33). For reference, the
APPENDIX contains individual test averages of all parameters for each
test. (See TABLES 60 through 80, starting on page 151.)
TF2 test conditions were also arrayed with respect to organic loading
rate. Selected parameters from the edited test period have been plotted
in FIGURES 4, 5, and 6 (pages 35, 36, and 37). (TF2 results are identi-
fied by a 2 preceding the test number). These TABLES and FIGURES will be
referenced in the following discussion.
-------
BOD Removal Efficiency Across TF2
Unsettled effluent from TF2 is quite variable in its BOD content and, for
this reason, will not be discussed except to note that efficiency of re-
moval without clarification, the effect of settling on BOD removal (i.e.,
efficiency across a clarifier), and the resulting efficiency of removal
with simulated clarification are all shown in TABLE 8 for TF2. In many
cases, significant amounts of BOD were removed from TF2 effluent by
settling. The result in all cases was a more consistent quality in the
effluent and it is this settled value which will be discussed.
For the 7 tests in which the feed for TF2 was pilot feed (PF) and the
recycle rate was 1 to 1 for feed, the settled BOD,, removal efficiency
tended to drop with increased organic loading (see FIGURE 6). There are
two exceptions which can be partly explained by extra strength influent
in one case and higher hydraulic loading in the other case.
BOD efficiencies based on settled effluent at the 1:1 recycle rate ranged
from 42 percent (organic loading of 620 ppd/1000 cf and hydraulic loading
of 6000 gpd/sf) to 65 percent (125 ppd/1000 cf and 4000 gpd/sf) . Black
liquor was being added in the former case.
The same general downward trend with increasing organic loading is also
found at zero recycle on TF2 as seen in FIGURE 4. For the tests iden-
tified with a "2", the efficiencies ranged from 36 percent (590 ppd/1000 cf
and 6000 gpd/sf) to 50 percent (150 ppd/1000 cf and 2000 gpd/sf) both
without black liquor. When black liquor was being added, only 13 percent
of the BOD was removed (1070 ppd/1000 cf and 6000 gpd/sf) .
Recycle rates of 0.5:1 and 2:1 were also run on TF2. BOD efficiencies
of between 60 and 64 percent were obtained at the 2:1 rate while less
than 45 percent was removed at the 0.5:1 rate as shown in FIGURE 5.
The dependency of the efficiency on the loading parameters will be exam-
ined later in this SECTION when the mathematical models are presented.
Solids Removal Across TF2
All determinations of solids content in TF2 effluent were made without
benefit of clarification on the mixed effluent. The changes in solids
across TF2 will be on this basis. TABLE 9 presents the average changes
for total solids, volatile total solids, suspended solids, and volatile
suspended solids. Negative values in this TABLE indicate an increase
rather than a decrease of the particular form of solids.
Total solids were found to decrease slightly (2.1 to 11.8 percent) on
the average in 11 of 19 test periods. Slight increases were noted several
times and increases greater than 50 percent were observed twice when
suspended solids losses were also significant. The volatile total solids
follow the total solids trend except the increase is at a greater level
in almost all cases.
30
-------
Large variabilities in the suspended solids forms would be expected since
the effluent was unsettled. This variability for suspended solids ranges
from a decrease of 62 percent in one test average to an increase of
168 percent apparently when the filter was sloughing. The volatile
suspended solids also show much variability for the same reason. Any
full scale trickling filter treatment plant should be designed with a
clarifier between the trickling filter and the river.
Apparent Color, pH. and Nutrient Changes Across TF2
Apparent color generally decreased across TF2 as shown in TABLE 10.
Four exceptions are noted and two of them correspond to feeds other than
PF. The treated effluent apparent color level generally ranged from
1000 to 1800 color units except when black liquor was present and the
level jumped to 3800 to 4600 units.
The pH level was consistently brought by the biological filter to an
average range of 7.2 to 7.6 except when black liquor was present and the
level jumped to an average range of 8.4 to 8.6.
Nutrient levels decreased significantly in all but five test periods.
There is incomplete correlation between decreases in ammonia and decreases
in phosphate. Other nutrient information will be given in SECTION VIII.
Dissolved Oxygen Levels in TF1 and TF2
Based on the individual test period averages in the APPENDIX, it can be
seen that the treated effluent from TF2 always carried a dissolved oxygen
level of above 2.4 mg/1 and usually greater than 5 mg/1. It is signifi-
cant that such a high level remained even after the requirements were
satisfied for the aerobic fixed bed biological process.
This aeration capacity of the trickling filter tower was the motivation
for the sludge recycle on TF1. The excess oxygen was utilized in TF1 as
evidenced by the average D.O. levels in the mixing ring being generally
below 1.0 mg/1 and often less than 0.6 mg/1.
Temperature Changes Across TF1 and TF2
The average data show temperature drops of 4° to 14°C across TF1 when PF
was feed (see APPENDIX). Across TF2, which did not have a clarifier as
did TF1, the average temperature dropped 3° to 10°C. When a filter was
preceded by the other filter or by the OD, the decrease was found to
range from only 1° to 4°C. The temperature decrease would certainly be
a function of ambient temperature and recycle rate.
Mathematical Models of Trickling Filter Results
Mathematical models have been presented by many investigators to express
the overall performance of trickling filters. These models generally take
the form of a retardant type equation of the following form:
31
-------
- = exp[-kAvt]
o
where
S is BOD concentration of filter effluent (mg/1)
S is BOD concentration of filter influent including dilution
effect of any recycle (mg/1)
k is biological rate constant
A is specific surface of particular media (sf/cf)
t is expression of exposure time in filter and is a function
of filter depth (D) , specific surface (A ) , and
hydraulic loading (Q) .
The biological rate constant k is dependent upon temperature as follows:
Generally t is expressed as:
t = AvD/Qn
The specific surface term (A ) may be included in an overall biological
rate constant, K, for the specific media and system, where:
K - kA
v
Eckenfelder (9) (10) has shown that the trickling filter model can be
expected to take the following form:
= exp [-K6T-2°D/Qn]
As the slime on the filter media represents a uniplanar surface through
which the oxygen must diffuse, it was assumed for the basis of the model-
ing that 6 would be 1.035 since this value has been reported previously
for trickling filter media. Thus, the overall biological rate constant
K and the hydraulic exponent n must be determined from the experimental
results.
The hydraulic exponent n was determined from data obtained during flow
tracer studies which are presented and discussed in SECTION VIII of this
report. The results of these studies are shown in FIGURE 7 (page 38),
with n determined to be 1.2 from the data. There are several points for
TF1 which fall off the curve in FIGURE 7. TF1 discharged directly to the
Clarifier 1 and it was difficult to obtain representative samples in the
32
-------
dye tests at the 24 foot depth. These points were disregarded in the
n determination. However, overall configuration of the filters and the
filter media was identical, so the n value should be identical for the
two units. The n value as determined by this analysis is used in
subsequent modeling of both trickling filters.
TF1 relations for the anticipated mathematical model were computed and
plotted in FIGURE 8 (page 39), from which the slope of the line would be
representative of the biological reaction rate K. Each of the four points
shown in this FIGURE represent an average of the respective functions
of all the test data which were obtained for that given recirculation
rate. These four points therefore represent the edited data which were
accrued over a two-year period of operation of the respective filter.
As can be seen, the reaction rate K for TF1 is 0.063. The effluent con-
centration to be expected, based upon the development of this model, is
presented in mathematical form in FIGURE 8. The base equation is:
S£ = S exp[-0. 063(1. 035)T~2°D/Qn]
and may be applied directly only when no recirculation flow is applied to
the filter as S is the BOD concentration of the effluent actually
contacting the filter media. Where recirculation is employed, as more
often occurs, then:
S + NS
s
o 1 + N
where
S = BOD of filter influent (mg/1)
3.
S = BOD of filter effluent (mg/1)
N = Percent recirculation divided by 100
Substituting into the base equation:
a o T 9n i 9
Se = 1 + N exp[-0. 063(1.035) D/Q 1
For the purpose of simplification let:
T-90 1 9
exp[-0.063(1.035) D/Q * ] = F
then
S F + NS F
s
e 1 + N
-------
The grouping of terms yields:
S (1 + N)-NF = S F
e a
which may be expressed in the simplified form as:
S F
S = a
e (1+N-NF)
FIGURE 9 (page 40) presents similar information for TF2 with each point
representing a composite of the data accrued over the entire test period
for that respective recirculation rate. As can be seen from this FIGURE,
the reaction rate K for TF2 was found to be 0.057. The mathematical
expression defining the effluent concentration to be expected from this
filter is also shown on FIGURE 9.
The effluent BOD concentration to be expected from TF2 would be expressed
as follows:
For no recirculation
T—9(1 1 9
Se = S exp[-0.057(1.035) D/Q ' ]
with recirculation
S F
S
e (1+N-NF)
Where
S = BOD of incoming wastewater
3.
S = BOD of influent mixture to filter
o
S = BOD of filter effluent
e
N = Percent recirculation divided by 100
T—90 i 9
F - exp[-0.057(1.035)L D/Q1"4]
A comparison of TF1 and TF2 is presented on FIGURE 10 (page 41). The
recycle to TF1 was clarifier underflow while TF2 had the more conventional
filter effluent for recycle. As can be seen, the reaction rate for TF2
is less than that for TF1. The magnitude of this difference is not great,
but the indication is consistent and represents a valid indication of the
relationship between the two basic systems. Thus, with all other condi-
tions constant, the recirculation of sludge would result in a slightly
higher degree of removal or a lower effluent concentration than with the
recirculation of unsettled effluent as is conventionally done.
34
-------
TABLE 11 (page 42) compares the observed effluent BOD concentrations and
removal efficiencies for TF1 to those levels which would be predicted by
the mathematical model presented above. Similar information is presented
for TF2 in TABLE 12 (page 43). In general the predicted efficiencies and
effluent BOD concentrations are well within 20 percent of those values
actually obtained. In a few cases there is no apparent agreement between
the observed values and those predicted. In these cases the feed was
either modified by black liquor additions or had been biologically
treated ahead of the trickling filters.
The biological reaction rate can be influenced by the character of the
wastewater. Therefore, the model should be negated when the feed is not
PF for which the model was developed. On this basis, the models do fit
the data within an acceptable tolerance.

SECTION VII
AERATED LAGOON TREATMENT
The Aerated Lagoon Process
The aerated lagoon is a basin in which oxygenation is provided by mechan-
ical or diffused aeration units or mechanical surface aeration. The
turbulence level maintained in the basin is a function of the power input
to the aerator and should be sufficient to insure distribution of oxygen
throughout the lagoon contents. Such power requirements are generally
much less than those necessary to maintain all the suspended solids in
suspension. Without sludge recycle, biological activity proceeds at a
much lower rate than in true activated sludge, thereby requiring detention
times measured in days rather than hours.
The process requires minimum control and has been often used where the
necessary land is available. Seventeen kraft mills in the U.S. are
operating aerated lagoons. More complete descriptions of the process can
be found in the literature (9)(12).
Project Results on Pilot Aerated Lagoon
A total of 13 test periods were completed on the pilot Aerated Lagoon (AL)
during the project. An additional two test periods on the pilot Oxidation
Ditch (OD) were conducted without sludge return. These two tests also
represent the aerated lagoon process (with a different type of aerator)
and so will be included in the analysis in this SECTION.
Laboratory settling of AL effluent was found to have a great effect on
BOD,, levels and so this sample modification was added with test AL-5.
The data prior to this test period were produced on an effluent sample
from AL without benefit of settling. Such a sample is termed "mixed" in
this report to distinguish from "settled" which infers the effluent from
clarification in the field or the supernatant from settling in the lab-
oratory in an Imhoff Cone. Beginning with test AL-5, all AL samples were
analyzed both mixed and settled for BOD . All determinations other than
BOD,, were on "mixed" effluent only.
TABLES 81 through 93 in the APPENDIX (starting with page 172) contain
averages of all test parameters on AL for each of the 13 test periods.
Both feed and effluent characteristics are shown. TABLES 13 through 15
(pages 50 through 52) show the test conditions on AL arrayed with
respect to detention time and contain the average change through treat-
ment of selected parameters. The format is similar to that explained
in SECTION IV.
53
-------
FIGURES 11 (page 53) and 12 (page 54) show the BOD results when the test
periods are arrayed with respect to average temperature in the lagoon.
These TABLES and FIGURES will be referenced in the following discussion.
BOD,. Removals Across Pilot Aerated Lagoon
Without clarification as shown in FIGURE 11, the BOD removal increased
with increasing temperatures from a low of 34.7 percent (16°C and 2.3
days detention) to a high of 69.7 percent (30° and 2.3 days). The pilot
Oxidation Ditch without clarification and sludge return was run concur-
rently with two of the AL tests. The detention times were longer in the
OD and the temperatures were 1°C higher but efficiencies were lower (i.e.,
57.3 percent vs. 60.3 percent and 67.0 percent vs. 69.7 percent in AL).
These differences in efficiency are slight and are not considered to be
significant.
When AL effluent was settled, as shown in FIGURE 12, the trend of in-
creased BOD removal with increasing temperatures was no longer evident.
Without settling, the removals were quite erratic. The efficiencies based
on settled effluent when PF without black liquor was the feed show a con-
sistency between 80.6 and 82.3 percent removal (except for test AL-7) at
temperatures ranging from an average of 14°C to 23°C and detention times
from 1.7 to 3.8 days. This unit and these results constituted very con-
sistent operation. A mathematical model of these results is presented
later in this SECTION.
It should be noted that a clarifier on the end of the pilot Aerated
Lagoon would have removed an additional 10.6 percent to 74.0 percent of
the BOD in the treated effluent. This effect of settling (see FIGURE 12)
appeared to be an inverse function of detention time, although exceptions
can be noted. The very significant reduction at short detention times
due to external settling should be considered in future designs.
Solids Removals Across Pilot Aerated Lagoon
Solids would not be expected to be removed consistently with short
detention time aerated lagoon treatment unless clarification is provided.
The fate of influent organic dissolved solids would be conversion to
biomass. This biomass plus suspended solids in the lagoon influent can
either settle out in the lagoon or be kept suspended (function of power
input) and thus overflow with the effluent. Settled solids in the bottom
can decompose and might add to the dissolved solids of the basin contents.
TABLE 14 shows that most forms of solids increased on the average across
AL during many of the edited test periods. These increases were inter-
spersed with significant removals in several tests. The overall pattern
is not clearly defined, especially when considering only data from the
edited test period which was chosen to represent equilibrium of BOD,.
efficiency. Clarification of effluent from a short detention time
aerated lagoon would be expected to result in reduced solids and to pro-
duce a more consistent effluent quality than can be reported here.
54
-------
Apparent Color, pH, and Nutrient Changes Across Pilot Aerated Lagoon
Average changes in apparent color, pH, and both added nutrient forms
across AL have been tabulated for the edited test periods and are,shown
in TABLE 15.
Reductions in apparent color did result in all but 3 tests and were above
10 percent in 9 cases. Note the distinction between "apparent color" as
is reported here and "true color" which is the solution color after the
solids have been removed and pH adjusted to 7.6 (see PROCEDURES).
Resulting apparent color values in the treated effluent when PF without
black liquor was the feed source were found to range from 1000 to 1750
with a single exception. The addition of black liquor raised the value
to 3400.
The pH changes through AL when PF without black liquor was feed always re-
sulted in final levels of 7.3 to 7.7 on the average for each test period.
The effluent pH value was higher both when AL followed OD and in the final
test with its long detention time which caused a drop in pH of 1.2 units
to a treated effluent pH value of 7.8.
Ammonia nitrogen levels decreased significantly through AL in all but one
test (a combination test with TF1) and in the final test when black liquor
was being added as seen in TABLE 15. Phosphate phosphorus changes were
not so well defined, probably because of the variable solids content in
the AL effluent.
Dissolved Oxygen Levels in Pilot Aerated Lagoon
Review of the average results for each test period on AL as contained in
the individual summaries in the APPENDIX will show that the dissolved
oxygen level being maintained in AL was significantly greater than 0.5
mg/1 in all but the last test period when black liquor was present.
Therefore, it is reasoned that dissolved oxygen was not limiting to the
biological process except in the last test. In that test the BOD,, removal
efficiency was the highest of any test and so the limitation, if actual,
is not apparent.
Change in Temperature Across Pilot Aerated Lagoon
On the average, as shown in the test period results for AL in the APPEN-
DIX, the temperature decreased during treatment by 7 to 17 °C when PF was
feed. The decrease was only 4°C when AL followed OD in series. The low-
est resulting temperature in the lagoon basin was 11°C. The temperature
change is a function of ambient temperature, basin volume, exposed
surface area and detention time.
-------
Mathematical Model of Aerated Lagoon Results
The mathematical model for a completely mixed aerobic system shows de-
pendency upon the influent and effluent concentrations, the biological
solids under aeration, temperature, detention time, and a reaction rate
constant which would be a function of both the makeup and character of
the wastewater being treated, as well as the biological system in which
the wastewater is subjected for treatment. Analysis of the aerated
lagoon data with respect to these various parameters indicated a best
fit by the mathematical form represented in FIGURE 13 (page 55). The
respective points which are shown represent the function of the average
of the data obtained during each particular test period. The range
marks radiating from the respective points indicate the data from the
individual weeks in each test average.
The mixed liquor volatile suspended solids were found to have little in-
fluence upon the mathematical model for the system. A major reason could
be the extremely Iqw solids content of the system, which would undoubtedly
be reflected to some extent in the biological rate constant k which was
established for this system. A reaction rate constant of 1.424 and a
temperature coefficient of 1.023 was established for the aerated lagoon
system. The average F/M ratio of the 5 points represented by the plot is
0.4. The line of best fit shown in FIGURE 13 was established by the
method of least squares.
The relationship is:
S " S-= 1.424(1.023)T"2°t
S
e
Where
S = BOD of influent (mg/1)
Se = BOD of effluent (mg/1)
t = Detention time (days)
T = Temperature (°C)
This relationship may be modified as follows to express the effluent BOD
to be expected from the unit directly.
Since the above equation can be expressed
•^ -1 = 1.424(1.023)T"2°t
56
-------
then
S

A comparison of the observed effluent BOD concentrations and efficiencies
with those which would be predicted by this model are presented in TABLE
16 (page 56). These comparisons indicate relatively close agreement
between those values observed and those values predicted except in the
cases where the feed had received biological treatment prior to the
aerated lagoon or where the feed had been supplemented with black liquor.
In both cases the quality of the wastewater had been modified. There-
fore, the biological rate constant would be affected. It is interesting
to note, however, that in a case where the feed had been supplemented
with black liquor and subjected to trickling filtration prior to the
aerated lagoon (test AL-12), the lagoon performed as would be predicted
for the unsupplemented primary feed when fed directly to the aerated
lagoon.

SECTION VIH
OXIDATION DITCH TREATMENT
The Oxidation Ditch Process
The Research Institute for Public Health Engineering in The Netherlands
conducted extensive research with the objective of reliable and economical
means of sewage treatment for small communities. What resulted in 1957
was the oxidation ditch treatment process which is essentially an extended
aeration process providing aeration in excess of 24 hours (15). For
economy and simplicity, an earthen ditch in the shape of a racetrack was
used for the aeration tank and air was provided by a horizontally mounted
aeration rotor. Intermittent operation of the rotor permitted the ditch
to serve also as the final clarifier in the first oxidation ditches.
The same effect can be accomplished by clarification of the ditch overflow
and return of the settled sludge back to the aeration basin.
The oxidation ditch or extended aeration process is generally operated
without controlled sludge wasting because the daily accumulation of sludge
solids in the system becomes negligible for sewage when the aeration
period extends beyond 18 to 24 hours. More details on the oxidation ditch
process can be found in the literature (5)(9)(15).
Successful application of the oxidation ditch process has been reported
in Ontario, Canada (15), Alaska (9), and other locations in the United
States (10)(18) for the treatment of sewage but the process has not been
employed previously in the U.S. for the treatment of kraft pulp and paper
mill effluents.
The fact that excess solids might be negligible coupled with the fact
that dewatering and disposal of secondary sludge solids can be an impor-
tant cost in industrial effluent treatment made an evaluation of the
oxidation ditch process very desirable. Its relatively long detention
time should minimize the effect of shock loads and reduce the need for
close control of the treatment process even on an effluent stream of
highly variable composition.
Project Results on Pilot Oxidation Ditch
A total of 8 test periods with clarification and sludge return were com-
pleted on the pilot Oxidation Ditch (OD) with Clarifier 2 (CL2) during
the project. Two other tests were conducted without clarification and
have been discussed in SECTION V. More testing was planned but mechan-
ical difficulties with the special chain drive arrangement on the pilot
brush aerator caused several serious delays. This same type of problem
would not be experienced with full-scale equipment since chain drives are
no longer being used, according to the manufacturer.
-------
The results from all test periods have been summarized on separate pages
and are contained with the respective Clarifier 2 results in TABLES 94
through 111 in the APPENDIX (starting on page 185).
The test conditions have been arrayed with respect to detention time and
depth. The average BODj. removals are shown in this format in TABLE 17
(page 62). The same format has been used to show solids changes across
this OD-Clarifier 2 system in TABLE 18 (page 63) and apparent color, pH,
and nutrient changes in TABLE 19 (page 64) . FIGURE 14 (page 65) shows
certain test parameters and BOD removal arrayed with respect to
temperature. These TABLES and FIGURES will be referenced in the following
discussions.
BOD Removals Across Pilot Oxidation Ditch Process
As can be seen in both TABLE 17 and FIGURE 14, the average BOD removals
for the oxidation ditch process employing sludge return were aBove 80
percent in all cases (except one) when PF without black liquor was feed
for the system. The highest removal at 1-day detention was 86.6 percent
at an average temperature of 30°C. Results from two test periods at 2-day
detention exceed that average removal. They were 89.8 percent at 27°C
and 93.7 percent at 29°C. The BOD removal in OD appears to depend more
upon temperature and detention time than expected. See mathematical model
at the end of this SECTION.
The most significant fact is that the process was run with no control
throughout the project once the feed rate, sludge return rate, and aerator
submergence were set for a given test period. All sludge underflow from
Clarif ier 2 was recycled to OD. None was wasted except for the incidents
relating to drainage of the OD and/or Clarifier 2 identified by date in
TABLE 40 of the APPENDIX (page 130) . Any buildup of excess sludge would
have been lost during these failures. The question, therefore, has not
been completely resolved concerning extent of sludge handling and dis-
posal facilities still required with the oxidation ditch process on kraft
wastewater.
Solids Removals Across Pj.lot Oxidation Ditch Process
The average solids reductions shown in TABLE 18 are based on a compari-
son between the feed to OD and the effluent from Clarifier 2 (except tests
OD-1 and OD-2) since the solids overflowing from OD are internally main-
tained at a high level for the biological process. With a single
unexplained exception, all measured forms of solids decreased across the
OD-Clarifier 2 system.
Suspended solids reductions ranged from 13.0 percent to 83.2 percent with
most ranging from approximately 50 to 67 percent. Average suspended
solids levels in the treated effluent ranged from 69 to 262 mg/1 when
black liquor was not being added. Other solids levels can be seen on the
individual test period summaries in the APPENDIX.
66
-------
Apparent Color, pH, and Nutrient Change Across Pilot Oxidation Ditch
TABLE 19 summarizes the results of changes in apparent color, pH, and
nutrients across the OD-Clarifier 2 system (tests OD-3 through OD-10).
Apparent color (i.e., with suspended solids not removed before testing)
decreased in all situations when the system feed was PF without black
liquor addition. Reductions ranged from 22.7 to 69.2 percent, leaving
final levels of 300 to 1350 color units in the treated effluent.
The pH changes through the treatment process were not great. Final
values in all cases ranged from an average pH 7.2 to 7.8.
The OD-Clarifier 2 system was an effective process for reducing ammonia
nitrogen and phosphate phosphorus. The ammonia reductions ranged from
32.2 to 95.5 with most reductions being over 75 percent. Phosphate
was reduced as much as 67.6 percent over the measured levels in the
feed. In one test period an average increase was recorded while in
another, a 6.4 percent decrease was found. Otherwise, the removals
were all above 30 percent. Additional information on nitrogen forms will
be presented in SECTION VIII.
Dissolved Oxygen Levels in Pilot Oxidation Ditch
Oxygen was always maintained at average levels above 0.9 mg/1 in the OD
basin at the point of overflow. Lower levels probably occurred toward the
bottom of the basin, especially when operated at the greater depths.
Several oxygen profiles are presented in SECTION VIII.
Change in Temperature Across Pilot Oxidation Ditch
Average temperatures as shown by individual test period for OD in the
APPENDIX dropped by 7°C to 12°C during treatment at the 1-day and 2-day
detention times. Such decreases for a given basin and aerator are a
function of ambient temperature and detention time.
Mathematical Models of Oxidation Ditch Results
The oxidation ditch data were analyzed in a manner similar to that for
the aerated lagoon. FIGURE 15 (page 66) shows the graphical solution
which was found to best fit these data. In this FIGURE, two graphical
relationships are presented. The average food to microorganism ratio
(F/M) of the system is the distinction.
One relationship is presented for an F/M ratio of 0.3. This F/M ratio is
considered to be in the range for normal aerobic biological treatment
design, although at the lower end. For this F/M ratio, a reaction rate
constant of 3.37 and a temperature coefficient of 1.063 is indicated.
67
-------
For the lower F/M ratio of 0.06 (indication of a starved condition in the
biological system), a reaction rate constant of 0.92 and a temperature
coefficient of 1.256 was found. As for the aerated lagoon modeling, all
points in FIGURE 15 represent functions of an average of the edited data
for that test period. The range over which those data extended is
indicated by the lines which radiate from the respective average points.
The following equations are derived from the graphical relationship
presented in FIGURE 15:

The effluent BOD,, to be expected from the oxidation ditch can be solved
from the models and is as follows:
For F/M = 0.3
S
S =
e 1+3.37(1.063)T~2°t
And for
F/M = 0.06
S
S =
6 1+0.92(1.256)T~2°t
The temperature coefficient is therefore found to decrease as the F/M
ratio increases from 0.06 to 0.3. This variance is probably due to
changes in the individual biological particles. When the F/M ratio is
in the neighborhood of 0.3, the particles are more flocculant and, as
previously discussed, the rate of oxygen diffusion into the flocculant
particle becomes the more limiting factor. In the case of extremely low
68
-------
F/M ratios and very high F/M ratios, a dispersed growth condition exists
and the influence of temperature is more direct on the individual organ-
ism and its biokinetics rather than on the more physical aspect of
oxygen diffusion.
In addition, the large 6 value for the low F/M ratio is undoubtedly in-
fluenced by factors other than the biokinetic rate as it is doubtful that
biokinetics alone could account for such a large 8 value. Other influences
certainly include the fact that the BOD values are based on settled rather
than filtered samples.
A single point with an F/M ratio of approximately 1 is shown about midway
between the two plots presented in FIGURE 15. The location of this point
might tend to indicate that as the F/M ratio increases to 1 or above, a
more dispersed growth condition is realized and subsequently the tempera-
ture effect upon the biokinetics of the system becomes more pronounced.
In all cases, the F/M values are based on mixed liquor volatile suspended
solids, which are suspected of containing a large portion of non-
biological volatile solids such as cellulose, and for that reason should
not be construed as absolute F/M values.
TABLE 20 (page 67) presents the observed efficiencies and effluent BOD
concentrations compared to those levels which would be predicted by the
respective models just presented. These models should be applied on the
basis of the F/M ratios indicated. As can be seen, the correlation is
quite high. It should be re-emphasized at this point that the data
used in developing these models, as well as those for the other biological
systems and the analysis of those models was based on settled BOD data
whereas filtered BOD data have been more generally employed by others
for such mathematical modeling and model comparisons.

SECTION IX
COMBINATION TREATMENT
Alternates for Combination Treatment
Flexibility was designed into the pilot treatment plant facilities in
order to allow multiple combinations of treatment units in series as well
as parallel operation. FIGURES 16 through 22 give schematic repre-
sentations of the ALTERNATES which were run during the project. Other
combinations were also possible. Results from the parallel operation of
all units as shown in ALTERNATE A have been discussed in the three pre-
vious SECTIONS. Combination test results will now be presented.
Nine combination test series were run during the project from which 12
separate combination tests can be identified as having mill clarified
effluent (called pilot feed or PF) for the system influent source. The
separate series by ALTERNATE with pilot unit sequence and test identifi-
cation were as follows:
ALTERNATE B - Trickling Filter to Aerated Lagoon (see FIGURE 17, page 76)
B-l (involves TF1): TF1-16 to AL-11

-------
The separate test period summaries in the APPENDIX contain the individual
unit results and show the "overall" BOD efficiencies for combination
treatment where applicable. The edited average values of efficiency have
been tabulated for each system and have all been presented in the previous
SECTIONS (See TABLES 5, 8, 13 and 17). Again, the notation of "overall
efficiency" is for combination treatment.
Both regular PF and black-liquor-dosed PF were used as feed depending
upon the test. The black-liquor-dosed feed will be indicated by (BL).
The following discussion will be limited to the BOD removal capability of
biological units following other biological units and the overall removal
actually demonstrated.
Aerated Lagoon Preceded by Trickling Filter
The pilot Aerated Lagoon (AL) was preceded first by Trickling Filter 1
(TF1) and later in a second test by Trickling Filter 2 (TF2). Black
liquor was being added in the second sequence. Average BOD removals for
the two edited test periods were as follows:
Conditions of AL Feed Unit AL Results Overall
I.D. Recycle gpd/sf BOD Removal Temp Time BOD Removal BOD Removal
TF1-16 0 6000 36.4% 15 °C 1.7d 80.7% 85.8%
TF2-17(BL) 0 6000 13.0% 11°C 1.8d 68.2% 74.1%
In both cases, AL was able to significantly reduce the BOD load being fed
to it from the roughing trickling filters. The first combination pro-
duced an effluent quality that was surpassed only by a detention time of
at least 3 days and higher temperatures in AL if used alone. The second
combination when black liquor was being added doesn't have a good basis
for comparison using AL alone. The other test on AL during the presence
of black liquor was at a detention time of 7 days and did give a better
efficiency than the TF-AL combination (compare final effluent quality of
146 mg/1 in combination test to 104 mg/1 in test AL-13).
Oxidation Ditch Preceded by Trickling Filter
The pilot Oxidation Ditch (OD) with Clarifier 2 was preceded by TF2 in two
different tests, both of which were run when black liquor was being added.
The second test had both filters ahead of OD. The average BOD removals
for the two edited test periods were as follows:
Conditions of OD Feed Unit OD Results Overall
I.D. Recycle gpd/sf BOD Removal Temp Time BOD Removal BOD Removal
TF2-17(BL) 0 6000 13.0% 16°C 2d 85.1% 85.6%
TF2 &
TFl(BL) 1:1 6000 56.9% 22°C 2d 75.5% 89.5%
-------
In both these cases, OD with Clarifier 2 was able to significantly reduce
the BOD load being fed to it from the roughing trickling filters. In the
first combination little was accomplished by the roughing filter, although
the effect to the further treatability of the effluent may have been
significant since OD was able to remove 85.1 percent of the remaining BOD
at the low temperature of 16°C even though other results showed OD to be
very temperature sensitive. A better basis for comparison would be de-
sirable. In the second combination, OD removed less BOD but contributed
to a higher overall removal since the filters in series had done so well
on the black-liquor-dosed wastewater. Final treated effluent BOD con-
centrations for the two combination tests were 88 mg/1 and 65 mg/1,
respectively.
Trickling Filter Preceded by Oxidation Ditch
TF2 was preceded by OD in one test period when black liquor was not being
added. Average BOD removals for the single test period are as follows:
Conditions of TF2 Feed Unit TF2 Results Overall
I.D. TempTime BOD Removal Recycle gpd/sf BOD Removal BOD^Removal
OD-8 27°C 2d 89.8% 0 6000 11.8% 90.4%
These TF2 results are plotted along with other trickling filter combi-
nations in FIGURE 23 (see page 82).
In this single case, the polishing filter was able to remove an addi-
tional 11.8 percent of the BOD even though the OD-Clarifier 2 system had
already achieved an 89.8 percent removal. The overall removal of 90.4
percent produced a final effluent quality of 16 mg/1 BOD5.
Aerated Lagoon Preceded by Oxidation Ditch
Two test series were attempted in which treated effluent from the OD-
Clarifier 2 system was fed to AL. A little over 3 months, consecutively,
were spent on this combination but the BOD content in the lagoon efflu-
ent never equilibrated with the low level being fed from OD. (Immedi-
ately prior to this combination, AL had received a much higher loading
which never got treated and/or diluted out completely.) In the two test
series, the BOD contents of the OD clarified effluent were 29 mg/1 and
12 mg/1, respectively, compared to edited test averages from AL of 32 mg/1
and 13 mg/1, respectively. No doubt the placing of a lagoon following
the oxidation ditch process would result in a more stabilized effluent
than could be demonstrated in this project. It is very doubtful that
supplemental aeration would be required in such a lagoon.
79
-------
Trickling Filters in Series
The tests about to be reported are not comparable to conventional high-
rate filters in series because TF1 always operated with Clarifier 1
(except test TF1-16 which was not a combination test) and the recycle to
TF1 was settled sludge, whereas TF2 was of conventional design with
filtrate recycle only. Therefore, when TF1 came first, as in ALTERNATE
F-l, the wastewater was clarified midway in treatment and again at the
end of treatment since TF2 effluent samples were settled prior to BOD
determinations. When TF2 came first in series, only the final treatea
effluent received clarification after passing through both filters.
Two test series were conducted in which TF1 was the feed for TF2. An
additional two test series were conducted in which TF2 fed TF1. One of
the latter tests was run while black liquor was being added to PF. In
all combination tests with both filters, the operating parameters for
the two filters were kept the same for a given test period.
These parameters, along with BOD removals, were as follows:
Feed TF Conditions Feed Unit Second Unit Overall
I.D. Recycle gpd/sf BOD Removal BOD Removal BOD Removal
TF1-11 1:1 4000 68.6% 6.7% 70.7%
TF1-14 1:1 4000 50.6% 69.1% 84.7%
TF1-13 1:1 4000 41.4% 48.7% 63.8%
TF2-18(BL) 1:1 6000 42.1% 34.6% 56.9%
The second unit results are plotted along with other trickling filter
combinations in FIGURE 23. In only one case of the filters in series
did the second unit not perform on an almost equal basis with the first
unit. The combination significantly improved BOD quality in the other
three cases. The respective final treated effluent BOD levels were
58, 31, 87, and 273 mg/1. 5
Trickling Filter Preceded by Trickling Filter-Oxidation Ditch Combination
A single test with three units in series was conducted through the final
phase of the project when black liquor was being added to the pilot plant
feed. This test period had TF1 on the end of the TF2-OD combination
reported earlier in this SECTION.
Essentially no additional BOD was removed by TF1 when this unit followed
the TF2-OD system. These TF1 results are plotted along with other
trickling filter combinations in FIGURE 23.
Applicability of Mathematical Models to Combination Treatment
The models presented in previous SECTIONS of this report were developed
for the particular pilot units when the influent feed source was PF with-
out supplemental black liquor and without previous biological treatment.
-------
These conditions force a limitation on the applicability of each model.
Therefore, combination treatment which involves one pilot unit receiving
the partially-treated effluent from another of the pilot units may not
correlate to the models. There are, however some cases of high corre-
lation for these situations.
The oxidation ditch model, for example, appears to hold where the effluent
is first subjected to single-stage or even 2-stage trickling filtration
when black liquor is present. (See tests OD-9 and OD-10.) However, such
an extrapolation is unjustified based of the limited information.
The aerated lagoon model did not respond well to any feed which had re-
ceived previous treatment, except in the case where the PF had been
supplemented with black liquor and subjected to trickling filtration prior
to the aerated lagoon. In a parallel instance where the unsupplemented
PF was subjected to trickling filtration prior to the aerated lagoon, the
agreement between that observed and that predicted is not good.
With respect to the trickling filters there is some indication that the
agreement between that which was observed and that predicted by the models
for feeds other than PF is reasonable at least part of the time, but not
always. For this reason, use of the model for any application other than
with PF as feed would appear unwise.
The general limitation of the mathematical models to the pilot feed source
for which they were developed is not intended to indicate that a combina-
tion model could not be developed, but only that the data which were
gathered during the course of the project were not sufficient to develop
other dependable models.

SUPPORT STUDIES
Aeration and Mixing in Aeration Basins
Surface aerators of the two types used in this project agitate as well as
oxygenate the basin contents. The degree of agitation or mixing is a
function of the power input to the basin but also depends upon the con-
figuration of the system and the particular aeration device.
Eckenfelder (8) has related the power input to degree of mixing for tur-
bine aerators. He shows that 0.006 to 0.01 horsepower is required per
1000 gallons of basin capacity (hp/1000 gallons) in order to achieve uni-
form dissolved oxygen. However, for suspension of activated sludge which
takes a minimum velocity of 0.4 to 0.5 feet per second, much higher power
levels are required and distance from the aerator becomes a factor. At
14 feet, 0.02 to 0.03 hp/1000 gallons are required, while at 35 feet
distance 0.05 to 0.06 hp/1000 gallons are required. These values show
approximately a 10-fold increase in horsepower requirements if the objec-
tive at 35 feet from the aerator is sludge suspension rather than just
uniform dissolved oxygen.
The aerators used in this project were the horizontally mounted brush
aerator in the racetrack-shaped pilot Oxidation Ditch, and the vertically
mounted turbine-type surface aerator in the square-shaped pilot Aerated
Lagoon. See FIGURE 24 (page 95) for dimensions of the basin.
It was possible to vary basin depth and aerator blade submergence, thereby
changing the power input to the basin contents. The resulting average
power loadings for the individual test periods in the pilot Oxidation
Ditch and Aerated Lagoon have been tabulated with other pertinent data in
TABLE 21 (page 96) . The BOD actually removed per net horsepower input
is also shown in this TABLE and should be of value in the design of
such systems.
The values are seen to range from 2.3 to 5.3 pounds of BOD,, removed per
net horsepower hour if the Aerated Lagoon effluent is clarified. Lower
values resulted if no clarification was provided at the actual test
detention times.
The Oxidation Ditch with brush aeration removed from 1.5 to 5.0 pounds of
BOD per net horsepower when operated with clarification and sludge re-
turn. Lower values comparable to the first tests on the Aerated Lagoon
resulted if no clarification was provided.
Support studies were conducted to obtain information on dissolved oxygen
levels, temperature, velocity and sludge depth at various points in the
two basins under different test conditions. The results of these studies
are summarized below.
91
-------
Dissolved Oxygen and Temperature in Pilot Lagoon
TABLE 22 (page 97) shows data from dissolved oxygen and temperature pro-
files in the pilot Aerated Lagoon. A total of eight studies were conducted
using the different testing depths in an overall basin depth of 6.7 feet.
Also included in the tabulated results of this TABLE are two tests per-
formed at a depth of 2.0 feet when the total basin depth was 7.7 feet.
In general, it can be seen that the basin contents were kept nearly
homogenous with respect to temperature and dissolved oxygen levels for
all power loadings which ranged from less than 0.01 net hp/1000 gallons
to greater than 0.02 net hp/1000 gallons.
The variance noticed most often is a 1.0-foot depth dissolved oxygen level
that is 0.1 to 0.4 mg/1 higher than the mid-depth value. The bottom dis-
solved oxygen level was never more than 0.3 mg/1 less than the mid-depth
value in these tests and frequently it equalled the mid-depth value. With
only one exception, the effluent levels were within 0.2 mg/1 of the 1.0-
foot depth average level. The reproducibility of the dissolved oxygen
probe in the field is no better than plus or minus 0.2 mg/1. Any correc-
tion for this variation could support the conclusion that the basin
contents were kept nearly homogenous for the power levels tested.
Velocities and Sludge Buildup in Pilot Lagoon
TABLE 23 (page 98) contains a summary of the data on velocities and
directions in the pilot Aerated Lagoon for two different general power
loadings and two different basin depths. Directions of flow are shown
for the highest power level input only since it is believed that the
meter was not sensitive enough to accurately indicate directions when the
velocity was far below 0.5 feet per second.
It is noted that for the power level above 0.01 net hp/1000 gallons, the
velocity profile is fairly uniform at a given test point. The surface
aerator is providing the same degree of agitation on the bottom of the
basin as it is close to the surface. Test points 5 and 6 are close to
the aerator as shown in the sketch and they have the highest velocities,
as would be expected. Points 3 and 4 together, and points 7 and 8 to-
gether, consitute equidistant extremes at 13.5 feet from the surface
aerator. For the highest power level test, the velocities ranged from
0.3 to 0.5 feet per second in a rather uniform fashion at this distance.
The situation changes as the power input drops below 0.01 net hp/1000
gallons. Although not so clearly defined in the last test in TABLE 23
as in the middle two tests, it can be seen that velocity definitely
drops off with depth at this lower power input. Again, highest
velocities occur closest to the aerator with minor exceptions.
Some sludge had collected on the basin bottom by this time and is so
indicated in this TABLE.
92
-------
Sludge buildup was recorded in separate testing during the project. A
chronological listing of sludge depth is recorded in TABLE 24 (page 99)
along with pertinent information on system operation.
The sludge depth was seen to increase much more when the lagoon depth was
7.7 feet and the power input was less than 0.01 net hp/1000 gallons than
when the depth was 6.7 feet and the power input was higher. As TABLE 24
shows, the pilot Aerated Lagoon ended up with 8 to 12 inches of sludge
on the bottom toward the end of the project (Test AL-13).
The sludge appeared to change position during Test AL-13 although the
major deposits were at those points farthest from the aerator, as would
be expected. The sludge sampled during Test AL-13 contained from 11 to
18 percent solids except under the aerator where it was very lean. The
volatile content of the sludge solids ranged from 26 to 38 percent,
thereby indicating some inorganic buildup within the aeration basin at
lower power levels.
The information taken at the test points may not necessarily be indicative
of sludge deposits in other locations of the pilot lagoon. In general,
it can be concluded that sludge builds up at a greater rate as power input
drops. Such a buildup is undesirable because it reduces the retention
volume of the basin and may eventually have to be removed. The other
objection involves the ultimate fate of the organic solids which get de-
posited. No information was developed during this project on the fate of
such solids, but it would seem likely that the BOD of the solids would add
to the BOD load of the basin, thereby requiring more oxygen in treatment
with passage of time.
Dissolved Oxygen and Temperature in Pilot Ditch
TABLE 25 (page 100)contains a summary of the dissolved oxygen and temper-
ature profiles found in the pilot Oxidation Ditch. Results from two
different basin depths at about the same loading are tabulated. The
trends observed here are different from those found in the pilot Aerated
Lagoon. The reasons are twofold. First, the power input was above 0.01
net hp/1000 gallons for all tests. Second, the energy input to the basin
contents from the brush aeration caused the total liquid volume to move
around the racetrack-shaped basin.
Vertical mixing is claimed by the aerator manufacturer because the blades
of the brush are gradually offset from one end to the other. The data
tend to substantiate this claim on vertical mixing because in all tests
the dissolved oxygen level was not found to decrease with depth. The
temperature was found to be uniform throughout the basin contents in all
tests.
Because of the "plug flow" beyond the aerator, a decrease in oxygen would
be expected as biological activity proceeds and the liquid follows the
path around and back to the aerator. Such a decrease, ranging from 0.2
93
-------
to 0.5 mg/1 is noted in all the data after the first test. It is con-
cluded that the oxidation ditch operation was completely mixed with re-
spect to temperature but was a short-term plug flow system as evidenced
by the change in dissolved oxygen level along the length of the tank.
Velocities and Sludge Buildup in Pilot Ditch
TABLE 26 (page 101) contains a summary of the velocity measurements made
in the pilot Oxidation Ditch for varying depths at power inputs above
0.01 net hp/1000 gallons.
When the oxidation ditch basin was at the 8.6-foot depth (Test OD-8 for
results shown) , the basin contents showed little motion below the first
5 feet, yet during the test series at a basin depth of 6.7 feet (Test
OD-1) , the basin contents were almost completely mixed with respect to
velocity except for surface values closest to the aerator.
Comparing the two -test series at depths less than 6.7 feet reveals nearly
complete mixing except in the last 12 to 14 inches of basin depth.
Here liquid motion was detected, but it was generally a trace to 0.1
feet per second.
In summary, it appears that the basin contents are kept in fairly uniform
motion under the influence of the brush type aerator at the power levels
studied when the depth is approximately 7 feet or less. Power inputs
greater than approximately 0.010 to 0.015 hp/1000 gallons would defin-
itely be necessary to keep the contents mixed as the basin depth is
increased beyond the 7 foot level.
Concerning direction of flow, no separate tabulation of these measure-
ments has been prepared because the directions at the higher velocities
do not differ greatly from the expected direction around the racetrack-
shaped basin. As stated earlier for the pilot Aerated Lagoon, no accu-
rate value can be read for the very low velocities sometimes encountered.
Sludge depth in the pilot Oxidation Ditch was studied with duration of
operation, but the mechanical difficulties required occasional drainage
of the system (see TABLE 40, page 130 in the APPENDIX). These interruptions
left no valid longterm data to be analyzed. In general, sludge deposits
on the bottom were sparse and never found to be more than two inches deep.
Accumulations were observed at the tank ends when the basin was emptied.
These accumulations were not more than several inches thick.
of Findings on Aeration and Mixing
In general, the following can be concluded:
Dissolved oxygen and temperature can be maintained uniformly at
lower power levels than required to keep solids suspended.
The aerated lagoon process will allow solids to be deposited on the basin
bottom at power levels that in the oxidation ditch will keep the solids
suspended .
94
-------
The directional flow capabilities of the brush aerator are very desirable.
Special BOD Studies
Some work was completed during the project on the relationship between
mixed, settled, and filtered 5-day BOD, COD to BOD,, ratios, and long term
BOD's of the pilot plant feed and the various system effluents. TABLE 27
(page 102) contains a summary of the BOD and COD test results.
It is noted that a greater part of the pilot feed (PF) BOD remained after
filtering than did any of the system effluents. In the case of effluents
from the pilot Aerated Lagoon (AL) and Oxidation Ditch (OD), the soluble
BOD values in May and October of 1969 ranged from 1 to 11 mg/1. The
trickling filter effluents were higher in soluble BOD^ except for the
test results on Trickling Filter 2 (TF2) when the feed to the system came
from the Oxidation Ditch.
The March to May, 1970 data in TABLE 27 show a changing COD to BOD ratio
through the treatment processes. The PF averaged 3.1:1 COD to BOD . This
ratio was changed in TF2 to 4.1:1 and in AL to 11.9:1, meaning that BOD
was destroyed more completely than COD during treatment, as would be
expected. The ratio was raised to approximately 9.6:1 when OD was fed
from the filters. The ratio reached 11.2:1 when TF1 was fed from OD that
was being fed from TF2.
The proportion of mixed to settled BOD for TF2 operating on the black-
liquor-dosed pilot feed which is symbolized PF(BL) was much higher than the
same system when the PF had only bleach liquor added to it and first passed
through TF1 (feeds of PF(2) and PF(3)). Compare 449 to 420 and 165 to 50.
These results imply that little of the total BOD5 was converted to settle-
able solids when the system was not being fed black liquor supplemented
pilot feed.
Concerning long-term BOD results, a total of six tests were run during
the project. Three samples of pilot feed or PF were tested and, during
each of these tests, one system effluent was also tested. The jug tech-
nique which was used did not cross-check with the standard BOD .
Therefore, the results are relative rather than absolute and should be
treated accordingly. A summary of the results follows:
Jug BOD (mg/1) BOD Ratio First Order
Date Sample 5-Day 21-Day 21-Day/5-Day Temperature Coefficient
4-28-69 PF 142 293 2.1:1 0.095
AL 57 128 2.2:1 0-054
5-19-69 PF 117 222 1.9:1 0.108
TF1 57 133 2.3:1 0.045
8-20-69 PF 159 337 2.1:1 0.135
TF1 80 205 2.6:1 0.074
95
-------
First order curves were fitted to the BOD data but in most cases do not
describe the data beyond about 10 days.
The pilot feed data in all three tests takes a second jump after 9 to 12
days and appears to be still rising after 21 days. The 21-day to 5-day
BOD ratio remains close to 2:1 in all three tests.
The AL data and the first set of data for TF1 are fairly well fitted by a
first order curve even out to 21 days where the curves level off. The
TF2 data took a jump after 15 days and was only beginning to level off
after 27 days.
The temperature coefficients for the first order portion of the long
term BOD curves for pilot feed ranged from approximately 0.10 to 0.14/°C
while the system effluents in the first two cases had temperature
coefficients of about 0.05/°C.
The trickling filter data that could not be fitted beyond 15 days by a
first order curve had a temperature coefficient of 0.074/°C- Ultimate
BOD values cannot be taken from the first order portions of the curves
which showed jumps. In any case, relative rather than absolute values
were obtained and it was for this reason that additional long term BOD
tests were not planned.
National Council (4) found an average ratio for COD to BOD of 3.8:1 for
raw filtered effluents from 8 different pulp and paper mills. With
biological treatment, this average ratio was raised to 16.3:1. A lignin
correction reduced the average raw effluent ratio to 2.2:1 and the treated
ratio to 4.4:1. They concluded that rapid BOD estimation based on the COD
test was not possible for kraft effluents because there were no fixed
relationships even with the lignin correction.
Kraft Effluent Interference to Winkler Dissolved Oxygen Test
Dissolved oxygen determinations are very important both in monitoring the
operation of biological treatment and in the measurement of biochemical
oxygen demand. Such determinations can be made chemically by the standard
Winkler test or polarographically by either the membrane electrode or the
dropping mercury electrode. Past investigators who have studied the
Winkler method versus the polarographic methods have found that the Winkler
method can give appreciably lower dissolved oxygen concentrations in
certain contaminated solutions.
McKeown (17) reported on comprehensive studies comparing Winkler results
to membrane electrode results in solutions containing pulp and paper mill
effluent and found the electrode measurement to be the better technique
both in the laboratory and in the field. Based on these studies, The Mead
Corporation has generally used the membrane electrode in field work
involving measurements of dissolved oxygen in treatment basins, rivers and
lakes. The membrane probe was used for all field measurements in the
96
-------
present project. However, its use in the laboratory for the BOD test was
limited generally to obtaining initial dissolved oxygen values of the
effluent samples before dilution and incubation. The standard Winkler
test was then run on the dilution water and, after 5 days, on the diluted
samples.
The effect of pulp and paper effluents on the Winkler test when diluted
6 to 150 times in the BOD test was considered to be slight. Comparative
tests during and after this project using a temperature compensated mem-
brane probe (see PROCEDURES) showed this assumption to generally be
correct if applied to the first 18 months of the project when the pilot
feed was taken as it came from the mill primary clarifier or when mixed
with bleach plant effluent. For these situations the membrane probe
values were slightly higher on the average but no trends could be defined
and there would be little effect in calculation of BOD's since a differ-
ence of readings is used.
Laboratory work did show that a correction is necessary for the Winkler
determination of dissolved oxygen when the pilot feed was being supple-
mented with black liquor during the final phase of the project. Inhibi-
tion of the Winkler value was found to be a function of sample volume
added to the BOD bottle and also a function of the method of treatment to
some extent. Corrections were derived for application to Winkler values
after incubation as follows:
True D.O. = Winkler D.O. + AD.O.
where, for PF, TF1, and TF2:
AD.O. = 0.131 x sample volume up to 10 ml,
and
AD.O. = 1.31 + 0.054 x (sample volume - 10 ml) for more;
while, for AL:
AD.O. = 0.097 x sample volume up to 10 ml,
and
AD.O. = 0.97 + 0.033 x (sample volume - 10 ml) for more;
and for OD:
AD.O. = 0.060 x sample volume up to 10 ml,
and
AD.O. = 0.60 + 0.019 x (sample volume - 10 ml.) for more.
As can be seen, the correction is greater for the pilot feed and the
trickling filters than for the aeration basin effluents. When the
systems were run in combination, the system effluent was corrected the
same as the unit it followed.
97
-------
In conclusion, it is very desirable that future BOD work on this type of
wastewater be conducted with the membrane electrode rather than the Winkler
test since the Winkler can be reading low part of the time and consistent
results may not be obtained.
Dye Studies on Pilot Systems
Several tracer dye studies were conducted on tne pilot system at the ter-
mination of the field testing in May, 1970. Black liquor was still being
added to the pilot feed at this time but its large consumption of dye
made its presence very undesirable, so it was removed. Since the pilot
feed was the only large volume source of water available at the site, it
had to be used during the dye studies.
Because of long detention times in the two aeration basins, the black
liquor content could not be flushed out in the available time. Response
analyses of the impulse inputs are, therefore, not possible because of the
uncertainty of remaining black liquor interference with and comsumption
of the dye. Therefore, only the times to the occurrence of peak dye con-
centration in these basins will be reported here.
The pilot Oxidation Ditch was being operated at a depth of 4.3 feet and a
theoretical detention time of 2 days. The power input during the dye
tests was greater than 0.02 net hp/1000 gallons, for which earlier veloc-
ity work would indicate an average velocity in the basin of at least
0.4 feet per second. The main dye peak occurred at a corrected time of
approximately 8 minutes. From this point, the dye concentration dropped
rapidly to a new plateau at approximately 30 minutes and then dropped
gradually after that. Another set of results showed a first peak at a
corrected time of approximately 7 minutes followed by a greater peak at
29 minutes. A once-around flow time at an average velocity of 0.4 feet
per second calculates out to 7.5 minutes. The favorable agreement of the
first peak in both tests strongly indicates a plug flow condition in the
pilot Oxidation Ditch. The second peaks must correspond to the second
circuit of the dye-dosed plug of water, only now the dye is spreading
and so the peak takes longer.
The pilot Aerated Lagoon was being operated at a depth of 7.7 feet and a
theoretical detention time of 7.0 days. The power input during the dye
tests was less than 0.01 net hp/1000 gallons, for which earlier velocity
work would indicate an average velocity in the basin of less than 0.3
feet per second. A principal dye peak occurred at a corrected time of
approximately 8 to 9.5 minutes depending upon the test. A second peak
showed up after a lag and could be interpreted as a cycle time due to
liquid motion caused by the aerator rotation, but by a second cycle the
basin influent would become well mixed with the existing contents. The
dye then tailed out over a period of many hours. Such results as were
obtained do favor interpretation of a well mixed condition in the pilot
Aerated Lagoon after the initial cycle.
-------
Results from dye studies on the Trickling Filters were analyzed to find
an "n" value to be used in the data modeling (7). The corrected peak
dye times through both filters were normalized with respect to column
height and a log-log slope was determined. The data were as follows:
Corrected Sampling Hydraulic Normalized Time
Peak Time Depth Loading (Minutes per
(minutes) (feet) (gpd/sf) Foot of Depth)
1.36 24 3150 0.057
2.90 24 3000 0.121
0.30 16 6000 0.019 X
0.70 16 3150 0.044 X
0.70 16 3000 0.044 X
0.24 8 4300 0.031 X
0.32 8 3150 0.041 X
0.35 8 3000 0.044 X
The line of best fit for these results fairly well satisfies the values
indicated with an "X" (see FIGURE 7, page 38). The "n" for this range of
hydraulic loadings is therefore found to be 1.20. Such a value is much
larger than others have reported for similar media (7); however, the
hydraulic loadings are also quite large. It is concluded that "n" is not
only a direct function of hydraulic loading but is also dependent upon
absolute loading rate.
The two clarifiers were also dosed with dye during these tests. A peak
in Clarifier 1 occurred 30 to 45 minutes after the dye was injected. The
theoretical detention time under test flow conditions was 4.1 hours, thus
indicating some short circuiting. Likewise in Clarifier 2, the dye peak
occurred at 18 to 36 minutes when the theoretical detention time was 1.8
hours.
Aeration Basin Oxygen Uptake Rates
Oxygen uptake rates were determined during the last phase of the project
when black liquor was being added to the pilot feed.
Initially only oxygen decay and temperature were recorded on the samples
with time. After the procedure was developed, several sets of data were
obtained for samples taken at varying depths at six points in the pilot
Aerated Lagoon. The suspended solids and volatile suspended solids of
the mixed liquor contents in the lagoon were also determined.
The initial data showed oxygen uptake rates in the pilot Oxidation Ditch
of 3.8 to 6.7 mg/1/hour, in the Trickling Filter effluents of slightly
greater than 1.0 mg/1/hour uptake, and approximately 2.8 mg/1/hour uptake
in the pilot Aerated Lagoon. The more complete data taken in the pilot
Aerated Lagoon are shown in TABLE 28 (page 103) from which several conclu-
sions can be made as follows.
99
-------
The Aerated Lagoon contents appear fairly well mixed in the areas and
depths sampled, as indicated by the almost random location of the highest
solids value in each test and also as indicated, especially in the case
of volatile suspended solids, the close agreement of all values in each
test with minor exception.
The oxygen uptake rate under similar test conditions on different days
appears to vary by more than 2.0 mg/1/hour. A greater uptake is calcu-
lated from the first hour's data than if the test proceeds for more than
2 hours. The overall range of oxygen uptake rates in this test series
is seen to be 2.4 to 4.9 mg/1/hour based on the first 60 minute values
in each determination.
Sludge Volume Index
Biological content sludge from OD and TF1 was settled continuously in
the two pilot Clarifiers and the sludge was recycled for the majority
of the test periods. The suspended solids content of both sludges was
found to be quite variable with extremes of 0.1 percent and 1.8 per-
cent being encountered.
An indicator of sludge settleability is the sludge volume index (SVI)
which relates the volume occupied by the settled sludge to the weight
of the suspended solids in this sludge.
The average SVl's for all test periods in which such information was
taken are shown in TABLE 29 (page 104) along with clarif ier loading rates
and detention times. It should be noted that the sludge volume index was
always below 100. Settleability of these sludges was quite good.
Results of Nitrogen and Phosphorus Levels After Treatment
Throughout the project the Main Clarifier effluent (MC) was tested for
existing nutrient content before setting the feed rate for addition of
aqua ammonia and phosphoric acid. At the end of every 6 months or
"Project Quarter" the rate was adjusted to compensate for existing levels
and still maintain a proportion of 5 pounds of ammonia nitrogen and
1 pound of phosphate phosphorus for every 100 pounds of applied BOD,.
(i.e., 100:5:1 for BOD5:N:P).
The mill clarified effluent with the additional nutrients added was then
designated Pilot Feed or PF and was also tested for final nutrient con-
tent. TABLE 30 (page 105) shows the results of testing for total and
soluble forms of nitrate nitrogen, total Kjeldahl nitrogen, ammonia
nitrogen, and phosphate phosphorus on both MC and PF by Project Quarter.
As can be noted in this TABLE, the most nutrients were added in the
fourth Project Quarter, which was when the black liquor was being added
to the MC for this project.
100
-------
TABLES 31 and 32 (pages 106 and 107) contain a similar summary of the
total and soluble nutrient forms still remaining in the TF1 and TF2
effluents after biological treatment. TABLE 33 (page 108) contains
the results from the pilot Aerated Lagoon and TABLE 34 (page 109)
contains pilot Oxidation Ditch results. Selected test conditions
are included in all four TABLES for the reader's benefit.
The very significant finding of this work is that high residual nutrient
levels still remained in the treated effluent when original dosages of
100:5:1 were provided. Future work should be directed toward the optimi-
zation of nutrient dosages so that a minimum cost for nutrients will be
paid and a minimum residual nutrient level will be discharged.
Chemical and Power Costs for Pilot Plant Operation
The chemicals used during the project were aqua ammonia (26°Be),
phosphoric acid (75 percent) and Hodag FD-62 defoamer (10 percent active).
Ammonia as nitrogen (N) was sixteen cents per pound and the phosphoric
acid as phosphorus (P) was forty-five cents per pound for the quantities
used in this project.
TABLE 35 (page HO) shows that over the entire project the nitrogen cost
an average of approximately one cent and the phosphorus about one-half
cent for every pound of applied BOD . TABLES 36, 37, 38, and 39
(pages in through 114) show the actual pounds of N and P required for
each pound of BOD removed for each test on the four pilot units,
respectively.
On TF1, the pounds of N ranged from 0.047 to 0.110 with an average of
0.079 pounds per pound BOD,, removed. The pounds of P ranged from 0.008
to 0.022 with an average of 0.014.
The TF2 unit showed a wider range from 0.085 to 0.684 pounds N required
with an average of 0.176 pounds N per pound of BOD removed. The P ranged
from 0.015 to 0.145 pounds with an average of 0.033 pounds.
On AL the range was 0.051 to 0.130 pounds of N per pound of BOD removed
with an average of 0.085 pounds. The P ranged from 0.008 to 0.026 with
an average of 0.016 pounds required.
The OD required an average of 0.054 pounds N with a range of 0.036 to
0.079 pounds per pound removed BOD . An average of 0.009 pounds of P
was required with a range from 0.006 to 0.016 pounds.
The average nutrient usage can be summarized as follows:
Ibs usage/lb BOD removed
Unit Nitrogen Phosphorus
TF1 0.079 0.014
TF2 0.176 0.033
AL 0.085 0.016
OD 0.079 0.009
101
-------
It should be noted that TF1 with sludge recycle "consumed" only half the
nutrients required for comparable operation in the conventional TF2 with
filtrate recycle. Furthermore, nutrient usage rate in TF1 based on
removed BOD5 is similar to the rate required in AL. Of the four units
on the average, OD consumed the least total nutrients, while TF2 consumed
the most.
The relative usage rates would be economically important if, in optimiza-
tion, the actual addition rates could be adjusted in the same proportion.
Using bulk prices of three cents per pound for N and fifteen cents per
pound for P, the nitrogen cost was approximately 0.2 cents and the phos-
phorus 0.17 cents for each pound of applied BOD over the entire project.
The defoamer was supplied at a cost of 52 cents per pound. Approximately
700 pounds were used during the project, resulting in a total cost of
$364.00 for defoamer. The bulk of this addition occurred during the
final four months when black liquor was being added to PF. (See the
Operation Procedures in SECTION IX.)
The power cost shown in TABLE 35 included the aerators, all pumps,
sample timers and lights. The electricity used in the pilot plant per
pound of applied BOD,, ranged from 1.1 to 1.8 kilowatt hours (KWH) .
At 1.5 cents per KWH, the electrical cost for this operation ranged from
1.7 cents to 2.7 cents per pound of applied BOD^.

PROCEDURES
Operation Procedures
Black Liquor Addition
During the final four months of the project, kraft black liquor was added
to the Pilot Feed to increase the BOD from approximately 200 to around
500 mg/1. The black liquor was digester blow-down containing 15 to 20
percent total solids and had an average BOD of 35,000 mg/1.
The black liquor flowed by gravity from the mill storage tank to a 50-
gallon gauging box at the base of the tank. The gauging box liquor level
was controlled by a BW Floatless Liquid Level Control System consisting
of 3 stainless steel electrodes (upper level, lower level and ground)
mounted on the gauging box, a BW Relay and 2 solenoid valves located in
the pipe connecting the black liquor tank and gauging box.
The liquor was pumped from the gauging box with a MOYNO Pump through 1/2
inch black iron pipe to the 4 inch Pilot Feed line approximately 700 feet
distant. This junction point was several hundred feet from the flow
splitting box, thereby resulting in adequate mixing of the black liquor
and mill clarified effluent before addition to the pilot units.
Defoamer Addition
Approximately 700 pounds of Hodag FD-62 defoamer were added to the pilot
units during the project. The defoamer was added when needed, rather
than on a continuous basis as were the nutrients. The bulk of the defoamer
addition occurred during the final four months when black liquor was being
added to the pilot feed.
The defoamer was added to the Aerated Lagoon at the aerator. The Oxida-
tion Ditch addition was made just downstream from the brush aerator. When
required for the filters, it was added in the flow splitting box. A normal
dose which was added manually was 2 to 3 gallons for each unit when needed.
Flow Measurement
Flows into each system were measured by V-notch weirs at the flow splitting
box each weekday morning. Flows into the lagoon and Oxidation Ditch were
infrequently double checked using a five-gallon bucket and stopwatch.
Effluent rate from the ditch was also checked by the bucket and stopwatch
method.
123
-------
Main Feed Pump Operation
The two main feed pumps (mill clarified effluent and bleach effluent) each
had a recording clock which accumulated the actual hours of operation for
the pumps. Normally the clocks were reset to 0 hours at a specified time
each morning, and the percent operating time was calculated for the pre-
vious day. This recorded evidence of pilot feed downtime was used in
editing test data.
Nutrient Addition
Nutrients were added to the main feed to maintain a total dosage of
100:5:1 (BOD:N:P).
The actual ratios by Project Quarters were:
100:4.5:0.9 for first quarter
100:3.9:0.6 for second quarter
100:3.4:0.6 for third quarter
100:5.2:1.1 for last quarter
Nitrogen was obtained from 26°Be aqua ammonia, and was added direct from
the drum. Phosphorus was obtained from 75 percent phosphoric acid (H PO.)
which was diluted 1 to 8 with water in order to obtain a pumping rate
comparable to the ammonia (approximately 30 ml/min.). Pumping was done
with a dual plexiglas head pump by Precision Pump Corporation. Rates
were checked daily to insure proper addition.
Power Consumption
Power readings on the brush aerator and surface aerator were obtained on
three-phase wattmeters connected to the respective units. Monthly read-
ings on all pumps, lights and other uses were taken by the Chillicothe
Area Electrical Department to determine kilowatt hours used per month
for the project.
Sampling
Samples of main feed, pilot feed and effluent from each system were
obtained using twelve minute interval timers and Little Giant submersible
pumps. The sampling period was sixteen hours per day (4 P.M. to 8 A.M.).
Samples were generally collected four days per week.
124
-------
Test Procedures
Ammonia Nitrogen
The distillation method for ammonia nitrogen was used. This method is
found in Standard Methods For The Examination of Water, Sewage and Indus-
trial Wastes, 12th Edition, 1965 (hereinafter designated "Standard
Methods") , pp. 391-92. Boric acid was used as the receiver in the total
and ammonia nitrogen testing.
Apparent Color
This test was performed on a Bausch & Lomb Spectronic 20 using one-inch
tubes, 400 millimicron wavelength, and platinum cobalt standard. Apparent
color was run on the sample as received. True color is obtained by
centrifuging the sample, adjusting the pH to 7.6, and reading the super-
natant solution. All color values obtained during the project were
apparent color.
Five-Day Biochemical Oxygen Demand tests were performed essentially as
stated in Standard Methods, pp. 415-21. Three hundred (300) ml bottles
were used for the tests. A 20°C water bath was substituted for the
refrigerator-incubator on August 1, 1968. An average of 184 IDO values
of dilution water showed 7.8 mg/1. After 5 days incubation, the dilution
water showed an average Dissolved Oxygen (D.O.) of 7.3 mg/1, resulting
in 0.5 mg/1 depletion due to seed.
The seed used was Paint Creek water above the mill clarifier outfall.
Amounts used ranged from 2.5 to 5.0 percent to keep the desired depletion
within 0.2 to 0.6 mg/1.
A standard glucose-glutamic acid solution (BOD of 221 +_ 10) was checked
frequently, resulting in an average value of 216 mg/1.
The initial D.O. in the sample and the D.O. in the seeded dilution water
after five days incubation were used to get the initial D.O. in calcu-
lating BOD results.
COD
Chemical Oxygen Demand tests were performed essentially as stated in
Standard Methods, pp. 510-14. The only modification was in the addition
of 1 gram of silver sulfate into the reflux flask rather than adding
22 grams into the 9 pound bottle of sulfuric acid.
125
-------
Dissolved Oxygen (see Temperature and Dissolved Oxygen)
Dye Studies
Tracer studies were conducted on each pilot unit using Rhodamine B
fluorescent dye. This dye was in acetic acid solution and had a solids
content of 40 percent.
The dye concentrations as fluorescence in the pilot units were read on a
Model 111 Fluorometer supplied by G. K. Turner Associates,
Fluorometer readings were taken both manually and by recording chart.
Chart speed was varied from one inch per minute to one inch per hour,
depending on the unit tested. During the early stage of each test, one
inch per minute recordings and manual readings were taken simultaneously
to insure accurate measurement. A continuous flow-through door was
utilized in the fluorometer for all the dye studies.
Kjeldahl Nitrogen
The procedure for this test is the total Kjeldahl method as described in
Standard Methods, pp. 402-04. The only deviation from the standard tests
was in using a new indicator specially made for ammonia. This is a com-
mercial product called N-point, available from Mathieson-Coleman-Bell.
Long Term BOD-Jug Method
This test was performed in the following manner:
1. Prepared 16 liter mixture of sample and dilution water containing
seed and nutrients. The ratio of sample to water was dependent upon
the BOD concentration of the sample.
2. Added the above mixture to a 5-gallon carboy and aerated to a D.O.
level of 7 to 8 mg/1.
3. Filled 6 BOD bottles from carboy by siphon technique. Placed open
carboy and the 6 filled and stoppered BOD bottles into a 20°C incu-
bator.
4. Winkler tests were run daily on 2 of the BOD bottles and the average
residual D.O. was recorded.
5. When the D.O. dropped to a concentration of 1 to 2 mg/1, the remain-
ing bottles were poured back into the carboy and reaerated to a D.O.
of 7 to 8 mg/1. After reaeration, the 6 BOD bottles were filled and
placed in the incubator. Daily Winkler tests were initiated again.
This cycle was repeated until the desired number of incubation days
was obtained, usually 20 to 30 days. The YSI polarographic D.O. test
was used in place of the Winkler method for the long term BOD studies
initiated August 20, 1969.
126
-------
Nitrate Nitrogen
This determination was made by the polarographic method using the Sargent
Manual Polarograph, Model III, and is essentially the test as shown in
Standard Methods, pp. 398-400. All samples submitted to chemical testing
for nitrogen were preserved with 0.8 ml sulfuric acid per liter of sample.
Oxygen Uptake Studies
These studies were conducted as described on pages 15-16 of The Instruc-
tions For YSI Model 54 Oxygen Meter. Yellow Springs Instrument Company
of Yellow Springs, Ohio supplied the Model 54 D.O. meter and 5420A D.O.
bottle probe. This probe was equipped with a rotary stirrer and auto-
matic temperature compensator.
The previously calibrated probe was placed into a 300 ml BOD bottle
containing the sample. Initial D.O. and temperature readings were taken.
Readings were then taken every 15 minutes until the D.O. level dropped
to 1 to 3 mg/1. The probe was kept in the sample in order to prevent
atmospheric oxygen from being absorbed. The sample was stirred continu-
ally during the test period.
The above procedure was altered as follows when six AL sample points were
run simultaneously. Each sample was placed into a BOD bottle which was
stoppered to prevent air entry. Each sample bottle was placed on a sepa-
rate magnetic stirrer for continual mixing. In order to prevent temper-
ature increase from the magnetic stirrer motor, the bottle was placed in
a beaker of water. When sample temperature started to rise, ice was added
to this water bath. Constant temperature control was very satisfactory
using this technique.
pH
A Beckman Zeromatic pH meter was used for pH testing. The meter was
standardized daily with pH 6.86 buffer solution.
Settleable Solids
This test was done as described in Standard Methods, pp. 425-26. Sludge
settleable solids were run for 30 minutes instead of the conventional
one hour.
Temperature and Dissolved Oxygen
Dissolved oxygen in the field was measured by the polarographic method
using a YSI Model 51 Oxygen Meter by Yellow Springs Instrument Company.
This meter was calibrated in saturated air at the sample temperature.
Occasionally a Winkler test was also run for comparison. This test was
done as described in Standard Methods, pp. 405-10, and is called the
azide modification of the Winkler test. Temperatures were taken with
the thermistor on the YSI meter.
12?
-------
Total Phosphate
Sample was wet ashed before starting test. The phosphate test is derived
from Standard Methods, pp. 234-36. It has been modified from Boltz by
substituting sodium molybdate and hydrazine sulfate for ammonium molybdate
and stannous chloride, respectively. A blue color is formed which is
read on the DK-2 Beckman Spectrophotometer at 830 millimicrons. During
the first quarter all soluble nutrient tests were centrifuged for 30 min-
utes at 85 G's. Tests were run on the supernatant liquid.
For the remainder of the project, the samples were filtered through glass
fiber filters as in the suspended solids procedure. Tests for soluble
nutrients were performed on the filtrate.
Total and Volatile Suspended Solids
These tests were performed as described in Standard Methods, pp. 424-25,
except for the use of glass fiber filters instead of the asbestos mat.
Sample volume was 50 ml, rather than 100 ml. A Mettler One Pan Automatic
Balance weighing to 4 places was used.
Total and Volatile Total Solids
Standard Methods, page 423, gives the procedure used for testing of total
solids. The Mettler balance was used for weighing.
Velocities and Sludge Depth
Flow direction and velocity were obtained in the Oxidation Ditch and
Lagoon using the Marine Advisors Q-9 Current Meter.
Sludge depths in the ditch and lagoon were obtained using a photoelectric
cell fabricated by the Mead Research Instrument Department.
Data Calculations
All daily solids (total and suspended) and BOD computations were sub-
mitted to the Computer Group for calculation and tabulation on the
digital computer. The raw data were submitted approximately every three
weeks, which resulted in a short time lag in obtaining final results;
however, this presented no problem in coordinating the data.

TABLE 41
-------
Explanation of Information in TABLES 42 Through 111
Reference is made to TABLE 42 (next page). The title "SUMMARY OF PILOT
TREATMENT UNIT RESULTS FOR TEST TF1-1" shows that this was the first test
performed on Trickling Filter 1. The influent or feed source was PF mean-
ing Pilot Feed.
AVERAGE OF ALL DATA, INFLUENT and EFFLUENT values were for the entire
test period as shown - 6/10/68 through 7/28/68.
EDITED DATA AVERAGES. INFLUENT and EFFLUENT. EFFLUENT MINIMUMS and
MAXIMUMS, and % REDUCTION were taken from 7/3/68 to 7/19/68 as shown.
There were twenty parameters tested, of which, for example, the BOD
(mg/1) "mixed" showed an all data average influent of 204 derived from
(15) values, and an average effluent BOD of 58 mg/1 from (14) values.
The edited data average BOD,, showed an influent of 224 mg/1 and an
effluent of 73 mg/1. Each number was derived from (6) values.
The range of the edited effluent BOD values was 52 to 87 mg/1.
The % reduction of the unit for BOD was 67.5 based on edited influent
and effluent.
Explanation of Information in SHEETS 1 through 60
Reference is made to SHEET 1 (page 203). The title "LISTING OF INDIVIDUAL
DATA BY DATE WITH EDITED DELETIONS INDICATED" refers to all individual
data obtained during the project and is tabulated by date with test
parameters identified in the first column and feed and system effluents
identified across the top of each day's block.
The four blocks in SHEET 1 contain the data for 6-21-68, 6-26-68, 6-28-68,
and 7-3-68, respectively. No routine data were recorded for dates not
listed.
The edited deletions are indicated by the word "DELETE" and pertain to
all data for that system on that date. For example, AL data were deleted
in total on 6-21-68 and 6-28-68, principally because acclimation was not
yet achieved in the opinion of the Project Leader. The test summaries
(TABLES 42 through 111) contain averages with and without the deleted
data included so it is possible to see the effect of deletions if
desired.

_ 27\Abstract A multi-unit pilot plant was used to study the biological treatment of
integrated kraft pulp and paper effluents after conventional primary clarification. The
biological units included two high-rate trickling filters packed with PVC media, an
oxidation ditch with brush-type aeration, and a lined earthen lagoon with mechanical
surface aeration. Simultaneous series and parallel operation of the four biological
systems was possible. The combinations using normal strength effluent included: (a) Trickling
filters in series, (b) Trickling filter to aerated lagoon, (c) Oxidation ditch to aerated
lagoon^ and (d) Oxidation ditch to trickling filter. Black liquor was added to the clarified
effluent in order to elevate the BOD^ level and the following combinations were tested:
(a) Trickling filter to oxidation ditch to trickling filter, (b) Trickling filter to
aerated lagoon, and (c) Trickling filters in series followed by oxidation ditch. The best
efficiencies were obtained on the pilot oxidation ditch when it was run with clarification
and sludge return as the extended aeration process. BODtj removals as high as 94 percent
were obtained. The trickling filter with sludge recycle performed better than the
conventional trickling filter. BOD<5 removals of 60 to ?0 percent were obtained. This
report was submitted in fulfillment of Grant No. WPRD-55 (12040-EMY) between the
Environmental Protection Agency and The Mead Corporation.
