ABSTRACT
The Chapel Hill high rate trickling filter plant which consists of two
parallel and equal lines of treatment units was operated in parallel as
two separate plants over a period of 26 months. Each side was operated
with various fractions of influent flow and recirculation flow rates.
Statistical analysis of operating results indicated that the common math-
ematical models are not reliable in predicting daily performance at the
Chapel Hill plant. They are, however, useful in predicting long term
average performance. Recirculation ratios as high as 3.0 proved benefi-
cial at total hydraulic loadings of less than 20 mgad. Operation above
this loading is not currently feasible at Chapel Hill.
The hydraulic surface loading of the final settling tanks was found to
have a significant effect on overall plant performance. A surface load-
ing of 500 gpd/ft is recommended for the design of final tanks in new
plants.
Pilot plant studies using 4-foot diameter rock filters indicate a signi-
ficant advantage for two-stage filtration even though the hydraulic load-
ing on each stage may be double that for single-stage operation.
Pilot plant studies of activated sludge treatment of trickling filter
effluent were conducted. The process proved effective in improving re-
moval of BOD, if effective final solids removal facilities are provided.
The process also proved effective in reducing nitrogenous oxygen demand.
This report was submitted in fulfillment of Project Number 11010 DGA,
Contract Number 14-12-505 between the University of North Carolina and
the U. S. Environmental Protection Agency.

SECTION I
CONCLUSIONS
A. TRICKLING FILTER STUDIES
To improve the performance of existing trickling filter plants with
a minimum of modification the following procedures are recommended:
1. If two filters are available, and two-stage or parallel opera-
tion of the filters is possible, the two-stage method should be
used as it will provide significantly better performance.
2. Filter recirculation ratios of up to 3.0 will significantly
improve the performance of most high rate filters. If pumping
capacity permits this level of recirculation, it should be used.
3. If filter recirculation is drawn from a point downstream of the
final settling tanks the entire plant flow plus recirculation
flow must pass through the tank. The final settling tank will
be much more effective as a solids separation unit if recircu-
lation is withdrawn before the final tank. Therefore, overall
plant performance will be improved.
4. The quality of anaerobic digester supernatant and its method of
return to the plant flow units can have a significant effect on
plant performance. The intermittent, high rate, return of
supernatant from a mixed digester will have a deleterious effect.
The continuous return of supernatant from an unmixed secondary
digester during periods of low plant flow, e.g., during the
night, will have little effect on plant performance. Therefore,
when two or more digesters are available, one unit should be
operated as a secondary to provide conditions for the thicken-
ing of sludge and the separation of supernatant.
The performance of some trickling filter plants can be improved with
minor additions or revisions, e.g.:
1. Additional recirculation pumping capacity may be provided by
installing larger pump impellers with higher horsepower motors.
Plant performance will be improved.
2. If two filters exist at a plant but no provision has been made
for two-stage filtration, the necessary facilities, i.e., pumps,
control boxes, and flow control systems, can be added to permit
two-stage operation. Two-stage filtration will improve perfor-
mance .
-------
When new trickling filter plants are being designed or major addi-
tions are to be made to existing facilities, the following factors
should be carefully considered:
1. Trickling filter plant performance is not significantly affected
by the point of recirculation return, i.e., ahead of the primary
settling tank or directly to the filter. For this reason direct
recirculation is recommended, as a smaller primary tank will be
required to meet design standards. The money saved in this
manner should be invested in larger final settling tanks.
2. Final settling tank design should be based on a surface loading
of 500 gpd/ft2. At this loading the performance of the tank
will be enhanced during both single- and two-stage operation of
filters. Furthermore, the settling tank will be suitable for
the separation of chemical floe if phosphorus removal or en-
hanced overall performance is required at some future date. In
this regard, structures to facilitate the future addition of
chemicals should be incorporated into initial plant construct-
ion. This would include provision for the addition of rapid
mixing, flocculation, and space for chemical storage and feeding
equipment.
3. At least two trickling filters should be provided along with
facilities and controls to permit two-stage operation and inter-
change of the lead and secondary filters. When the proposed
facility is so small that two filters are not economical,
another treatment method should be considered.
4. Existing mathematical models and models developed during this
investigation are not reliable predictors of the daily perfor-
mance of the Chapel Hill high rate trickling filter plant. The
models developed during this study are, however, suitable for
the prediction of average performance over a period of several
weeks.
B. ACTIVATED SLUDGE PILOT PLANTS
1. An activated sludge process is readily maintained with trickling
filter effluent as feed. The process significantly, but not
spectacularly, improves overall removals of BOD , total organic
carbon, and suspended solids. Short (< 1 hr) aeration periods
suffice to increase overall BOD removals by 3-5%. BOD removals
generally increase with detention time.
2. Consistent performance of the tertiary activated sludge process
depends to a large extent on effective solids removal. With
effective solids removal substantial BOD removals can be
achieved even at 0.4 hr detention. With effective removal of
suspended solids, overall BOD removals greater than 90% can be
achieved.
-------
3. Extensive nitrification can be achieved in the tertiary acti-
vated sludge process. Significant reductions of organic and
ammonia nitrogen concentrations indicate that substantial re-
duction of the nitrogenous oxygen demand (NOD) can be accom-
plished. The amount of NOD reduction is largely a function of
aeration time and BOD loading. In the relatively soft Chapel
Hill water addition of bicarbonate alkalinity enhanced nitri-
fication.
NOD removals of greater than 80% were achieved under conditions
of low influent BOD concentration (35 mg/Z), bicarbonate addi-
tion, and 1-9 hr detention time. With an average influent BOD
of 72, more than 4 hr were required.
With low influent BOD levels, even at short aeration times (< 1
hr) NOD reductions of greater than 50% were observed.
Extensive nitrification (> 90%, based on removal of influent
ammonia) frequently occurred when the pH in the aerator averaged
less than 7.0, leading to the conclusion that the optimum pH
range for nitrification is not as narrow as indicated by pre-
vious investigators.
Based on these studies, if NOD reduction is required in upgrad-
ing an existing trickling filter plant, terminal activated sludge
treatment may provide an acceptable solution. If NOD reduction
is required in a new plant, trickling filter treatment followed
by activated sludge treatment may allow the activated sludge
system to operate more successfully due to the dampening effect
of the filter on changes in influent quality.

SECTION II
RECOMMENDATIONS
A. TRICKLING FILTERS
1. New trickling filter treatment facilities should be designed for
two-stage operation with provision for interchange of the lead
filter.
2. The effectiveness of intermediate settling between filter stages
should be determined.
3. Studies of deep filters designed to operate at high hydraulic
loadings, with continuous rather than intermittent liquid appli-
cation, would help in the verification or modification of ra-
tional filter performance models as developed by Rowland,
Schulze, and Eckenfelder. With the proper experimental opera-
tion of such filters the effect of both liquid detention and
liquid turbulence might be determined. The systematic develop-
ment of deep filters or multi-stage filtration processes design-
ed to operate at high hydraulic loadings could result in signi-
cant economies while the traditional advantages of the trickling
filter process, i.e., simplicity of operation and resistance to
upset, could be retained.
4. Final settling tanks in new trickling filter plants should be
designed at an average surface loading of 500 gallons/day/ft .
Designers should provide for the future addition of chemical
treatment, i.e., provision should be made for the installation
of mixing and flocculation equipment prior to final settling.
B. ACTIVATED SLUDGE PILOT PLANTS
1. The effect of pH, alkalinity, and organic loading on nitrifica-
tion systems should be examined further. Whereas such factors
have been extensively investigated in laboratory studies with
defined media, further information is needed on their effect on
actual treatment systems. In addition, development of a good
method for determining the relative numbers of nitrifiers in a
given sample of sludge would be useful in formulating a valid
description of the relationship of mixed liquor suspended solids
concentration to nitrifying activity.
2. The effectiveness of the trickling filter - tertiary activated
sludge process should be verified at full-scale. In particular,
the following parameters need assessment: temperature varia-
tions, sludge production, control of effluent solids.

SECTION III
INTRODUCTION
A great many secondary municipal wastewater treatment plants in the
United States use trickling filters as the biological units. Most of
these are "high-rate" installations, characterized by relatively heavy
rates of wastewater application with recirculation of treated effluent
to dilute influent before application to the filter. Typically, trickl-
ing filter plants attain 70-85% BOD removal through the entire facility ,
including removal of about one-third of the influent BOD by primary
sedimentation.
Modern technology of wastewater treatment and pressures for higher re-
movals of BOD, suspended solids, and other constituents have resulted
in trends toward installation of activated sludge instead of trickling
filters in new plants. Nevertheless, thousands of communities in the
U.S.A. still have trickling filter installations. Most perform at a
level which is, or soon will be, inadequate for meeting regulatory re-
quirements, leaving those municipalities in the situation of having to
enhance plant efficiency. That could be accomplished through merely en-
larging existing facilities, adding other types of treatment processes,
or replacing their trickling filters with other types of units.
Information currently available to design engineers and operating per-
sonnel is inadequate to permit accurate selection of optimum systems for
enhancing performance of trickling filter plants to levels that might
be required. The overall objective of this project was to develop infor-
mation which could help design engineers and operating personnel select
among practical alternatives available for improving performance of
trickling filter plants.
The general approach was based on experimental investigations at labora-
tory, pilot- and full-scale. They were conducted at the Mason Farm
Sewage Treatment Plant in Chapel Hill, North Carolina, operated for the
Town by personnel in the Department of Environmental Sciences and Engi-
neering at the University of North Carolina. The most recent plant
enlargement (1968) included modifications to provide unusual flexibility
in full-scale operation, as well as facilities for laboratory and pilot
studies. Among other unusual features, the new units were designed to
permit operating the plant as two separate identical trickling filter
installations, between which the influent flow could be divided in any
desired proportion with capability for independent control of recircula-
tion and other aspects of operation in each.
The experimental program was designed to develop practical information
which would be valuable to engineers engaged in modifying trickling
filter plants to improve performance and to evaluate techniques which
-------
could be applied by plant operators to assure optimum performance of
existing and proposed units. Activities were directed principally to-
wards evaluating the effects of various parameters on treatment effici-
ency and investigating the performance of an activated sludge system
based on installation of an aeration tank between the trickling filter
and final settling tank. Each investigation involved use of several
experimental facilities to study various aspects of operation, as will
be discussed in detail in appropriate sections of the report.

SECTION IV
CHAPEL HILL PLANT AND WASTEWATER RESEARCH CENTER
A. Plant Design
The Wastewater Treatment Plant for Chapel Hill is a conventional high-
rate trickling filter installation treating predominantly domestic sew-
age. There is substantially no industrial or other unusual contribu-
tion, except for hospital and laboratories of the University of North
Carolina. Table 4-1 summarizes some of the more pertinent characteris-
tics of the influent for the period of this study, 9/69-1/72. Figure
4-1 is a partial flow sheet for the Plant and Table 4-2 summarizes
characteristics and design parameters of major units.
Incoming wastewater passes through a mechanically cleaned bar screen,
with a manual unit serving as a backup in case of failure. Subsequently,
the flow is metered and grit removed in a detritor. Design of the grit
removal effluent structure allows splitting of flow into any desired
proportions for diversion to the two identical treatment plant batteries.
Based on total plant influent of 3.0 mgd, equally divided between the
two batteries, and recycle ratio of 2:1 the 70-foot primary clarifiers
provide 1.8 hours detention and overflow rate of 1180 gals/ft^/day.
Each trickling filter is 120-feet in diameter with a stone depth of 4.25
feet, providing a "design" loading of about 35 Ibs. BOD/day/1000 cf
(assuming one-third removal in the primary) at hydraulic loading approxi-
mating 17 mgd/acre. Trickling filter effluent passes through a wet well
from which any or all of three pumps take recycle at rates up to 7.5
mgd in each battery. Net plant flow (no recycle) passes to 45-foot
final clarifiers, providing 1.9 hours detention at 1.5 mgd and 960
gals/ft^/day at 1.5 mgd through each battery.
B. Plant Operation
Normal plant operation is based on recycle to the primary clarifier
influent, but a connection has been provided to permit recycling directly
around each trickling filter, without settling. Series or stage opera-
tion of the filters is not possible. Typically, the plant operates with
the batteries in parallel, as shown in Figure 4-1, in effect providing
two separate treatment facilities. The influent sewage can be divided
between these as desired for operation at different loadings and recycle
in each adjusted independently.
Sludge from each final settling tank is pumped to influent of the pri-
mary clarifier, in which it settles again in combination with primary
sludge. Sludge and scum are pumped from primary clarifiers to a 75-

foot diameter digester equipped with floating cover and mixer. A 50-
foot diameter digester, with infrequently used mechanical mixer, serves
as a second stage digester. Supernatant from the secondary digester is
decanted during periods of low plant flow at a low rate of flow to the
plant influent. Gas produced in the process is utilized for heating
the sludge digesters and the excess burned in a flare.
Digested sludge usually is dewatered on 18 uncovered sand drying beds.
When required by weather unfavorable for sludge drying, a centrifuge is
available for dewatering. This unit also may be used for dewatering
undigested sludge if unusual circumstances require reduction of loading
on the sludge digesters.
C. Sampling Procedures
Since the plant is only staffed by Chapel Hill for 8 hours each weekday
and not at all on weekends, it was necessary to construct an automatic
sampling system. Sampling points include influent, effluent from each
primary tank, effluent from each trickling filter, and effluent from
each final tank. The samples flow by gravity or are pumped continuously
to overflowing standpipes in the operations building. A timer-controlled
Blue pumpl pumps sample water to a solenoid flop valve^. The valve is
in a "waste" position for a sufficient time to purge all of the sample
lines (approximately 60 sec.). The valve is then switched to the

Analytical and research laboratories at the Center occupy six rooms with
total area of 1300 square feet. Two rooms are equipped for close tempera-
ture control. One is used principally for BOD analyses and the other for
fish bioassay studies or biological treatability studies.
The routine analytical laboratories are equipped for a wide variety of
physical, chemical and biological work, including TOC, BOD, COD, various
types of solids, turbidity, pH, volatile acids, and microbiological
studies. An extensive array of Technicon Autoanalyzer equipment is avail-
able in Departmental laboratories on campus with units for determining
all forms of nitrogen, phosphorus and MBAS. Also, an atomic absorption
spectrometer is available in the Departmental laboratories, as well as
many other types of specialized equipment which are available as may be
desired.
About 500 square feet of additional space is available in the main build-
ing at the plant for bench-scale and small pilot equipment. Units avail-
able in this location include five 0.1 gpm activated sludge units which
were used extensively during early phases of these studies. Adjacent to
that building is an installation of four 4.0-foot diameter pilot trickling
filters in a separate enclosure of about 400 square feet. An outside
view of these units is shown in Figure 4-3.
A new prefabricated metal building at the Center encloses 1800 square
feet of offices and space suitable for constructing and operating larger
pilot plants. This building is shown in Figure 4-4.

followed by orthophosphate determination. Ammonium molybdate reacts with phos-
phorus in an acid medium to form a phospho-molybdate complex. This complex is
reduced to an intensely blue-colored complex by hydrazine sulfate. The color

SECTION V
TRICKLING FILTER STUDIES
A. OBJECTIVES
For years, prior to the advent of package aeration plants, the trickling
filter process predominated in small and medium sized wastewater treat-
ment plants. Filters have the advantage of being able to quickly re-
cover from shock loads and will provide good performance with a lower
level of skilled technical supervision (4). The initial costs of trick-
ling filter plants are comparable with those for activated sludge; how-
ever, operating costs are lower as power costs are substantially less
(5).
A number of mathematical models have been suggested for predicting the
performance of trickling filters [Velz (6), NRG (7), Rankin (8), Rowland
et al. (9, 10, 11, 12), Schulze (13, 14, 15), Stack (16), Eckenfelder
(17), Caller and Gotaas (18), Lamb (19)] but there are significant dif-
ferences in factors included in the models and in the performance pre-
dicted under similar conditions. Accordingly, one of the principal ob-
jectives of the experimental work described in this chapter was to deter-
mine if a reliable predictive model could be developed for the Chapel
Hill plant and to examine the effect of several variables on filter-final
tank performance.
Other objectives were 1) to study the effect of the pattern of recircula-
tion on plant performance, 2) to investigate the probable effect of con-
verting the Chapel Hill plant from single- to two-stage filtration and
3) to examine the effect of final settling tank loadings on plant per-
formance. Because it was impossible to operate the Chapel Hill plant in
two-stage filtration, this phase of the work was conducted with the use
of a pilot plant. Data for other phases of the study were drawn from
the operation of the full scale plant.
B. EXPERIMENTAL PROGRAM
During the period from November 18, 1969 through January 24, 1972, the
two sides of the full scale Chapel Hill plant were operated experimentally
to investigate the effect of a number of variables on plant performance.
The three factors which could be varied were
1) the fraction of influent flow which could be directed to
each side of the plant
2) the recirculation flow on each side of the plant
3) the pattern of recirculation.
18
-------
During the experimental program the fraction of influent flow to each
side of the plant was manipulated with the use of the division plate
downstream from the grit removal chamber. Flow divisions ranged from a
0-100 percent split to a 50-50 percent split. The various divisions
used during the experimental program were 50-50, 33-67, 20-80 and 0-100.
The 0-100 percent division experiment was conducted during a period when
one of the filters was out of service for an extended period to replace
filter distributor arms.
Recirculation flow was varied with the use of various combinations of the
three recirculation pumps available on each side of the plant. Minor
variations were obtained by throttling individual pump discharges. Dur-
ing the experimental program recirculation flow varied from 0.65 mgd to
4.20 mgd.
The ability to vary influent flow division to each side of the plant
and the recirculation flows allowed variation in other factors which
are normally included in mathematical models for predicting trickling
filter performance, i.e., hydraulic loading, organic loading and re-
circulation ratio. During the series of experiments the hydraulic load-
ing on the filters ranged from a low of 5.4 mgad to a high of 22.5 mgad;
organic loading, from 265 to 35 Ibs BOD/day/acre-feet (6.1-80.5 Ibs/day/
1000 ft^); and the recirculation ratio [(recirculation flow)/(influent
flow to a side)], from 0.27 to 6.94. Wastewater temperature was
recorded daily and ranged from a low of 11.0 °C to a high of 28.0 °C.
During the experimental work sufficient data were obtained with equal
influent flow division and equal recirculation flows on each side to
determine whether the two sides of the plant would produce equal results
under equal loading conditions.
The pattern of recirculation flow was also varied during one period. The
normal pattern of recirculation at the Chapel Hill plant is to return
filter effluent to the head end of the primary settling tank. An alter-
nate method permits recirculation directly around the filters.
C. SAMPLING, ANALYSES AND DATA HANDLING
During the experimental program with the full scale trickling filters
daily composite samples of wastewater were obtained from the following
points in the plant:
Influent, following screening and grit removal
Primary Settling Tank Effluent, from each of the two primary
settling tanks
Trickling Filter Effluent, from each of the two filters
Final (Secondary) Settling Tank Effluent, from each of the
two final settling tanks.
19
-------
Samples were collected with a heavy duty multitube type pump. During
the sampling cycle all sample pump discharge lines were flushed before
the sample was diverted to the accumulation containers. Sample contain1-
ers were stored in a cold chest held at approximately 4° C. All analyti-
cal and operating data collected during the main plant experimental pro-
gram are shown in Appendix A. Analytical procedures are described in
Section IV.
Several months after the initiation of data collection it was realized
that accurate analysis of the data being accumulated would require the
use of a computer. It was decided to store all of the main plant data
on a computer generated file from which specific data could be selected
for report printing or statistical analysis. In addition, it was felt
that the data collected during this study would be of use to other in-
vestigators and should be in a form that could be readily transferred.
Rather than develop our own file-handling system, we utilized the file
capabilities of a system known as the Statistical Package for the
Social Sciences (SPSS, National Opinion Research Center, University of
Chicago). This system allows calculations from raw data and storage of
new variables such as hydraulic loading. In addition, the statistical
section of SPSS allows ready statistical analysis of any or all data in
the master file. If SPSS is unsuitable for a particular report format
or statistical analysis, it allows the creation of an output file which
may then serve as an input file to any other statistical or report-
generating program.
The entire master file for the period November 19, 1969 to January 24,
1972 is permanently stored at the Computation Center of the University
of North Carolina on a magnetic tape, UT3500. Requests for copies of
this tape and the tape format may be addressed to the authors. The data
in this file is reproduced in Appendix A of this report.
D. EQUALITY OF THE TWO SIDES OF THE PLANT
One of the principal objectives of the experimental work with the main
plant was to determine the effect of the several variables, i.e., organic
loading, hydraulic loading, recirculation ratio and temperature, on plant
performance. The logical first step was to determine if the two sides
of the plant would produce comparable results under conditions of equal
loading and temperature on each side. Accordingly, during three separate
periods within the experimental program, the operating variables were
constant. The mean overall plant performance in terms of percent removal
of BOD5, SS and TOC is shown below:
20

Statistical analysis of the individual items of data which resulted in
the mean removals shown in Table 5-1 indicated that the two sides of the
plant could be considered equal in regard to performance when operated
under the same loading conditions. This is an important conclusion as
it allowed the data collected on Side 1 to be analyzed with the data
collected on Side 2 as if all observations had been made on one side only.
E. PATTERN OF RECIRCULATION
The effect of recirculation pattern on plant performance was studied by
recirculating filter effluent through the primary settling tank on one
side of the plant, while recirculating directly around the filter on the
other side, as shown in Figure 5-1.

This method of operation was maintained during the period from 7/16
through 8/24/72. The pattern of recirculation on the two sides was re
versed during the period 9/8 through 9/21/71. Influent flow ^as split
50-50 and the recirculation ratio was maintained the same on botn siaes
during each test period. During both experiments, the side in wnicn re-
circulation was through the primary tank yielded slightly better pertor-
mance. Average results in terms of overall removal of BOD and bb on tne
two sides are shown in Table 5-2.

One important effect of recirculation through the primary tanks in the
Chapel Hill plant is the reduction of odors. Filter effluent normally
has a dissolved oxygen concentration of 4 to 6 mg/1. The mixing of re-
circulated flow with raw sewage tends to keep the mixture reasonably
fresh as it passes through the primary settling tanks. Primary settling
tank detention time at the Chapel Hill plant, at an influent flow of 3.0
mgd and a recirculation ratio of 2.0, is 1.9 hours. When recirculation
is directly around the filter the detention time in the primary tanks
increases to 5.4 hours and serious odor problems result.
F. MATHEMATICAL MODELS FOR TRICKLING FILTER PLANT PERFORMANCE
As mentioned previously various mathematical models have been suggested
by different investigators. Although engineers have used these models
as a convenient design tool, none have been generally accepted as a
truly reliable predictive device. Any model which is generally valid
would be an aid to optimum filter design or to more efficient operation
of existing plants in cases where the designer has provided some degree
of operating flexibility.
Mathematical models for trickling filter performance can be divided into
two general types, i.e., regression models and rational or semi-rational
models. Existing models are all based on predicting removal of BOD.
Accordingly, the BOD data collected in the Chapel Hill plant were ana-
lyzed in comparison with several widely known models. In addition a new
regression equation was developed specific to the observed BOD removal
at Chapel Hill.
22
-------
It should be noted that all trickling filter models discussed here are
designed to predict removal of BOD through filters and final settling
tanks, where the final settling tank is considered to be an integral part
of the filter system. Little attention has been given to the effect of
final settling tank detention time or surface loading on combined per-
formance of the system.
1. Regression Models
Caller and Gotaas (18) developed a regression equation to fit 322 obser-
vations from various trickling filter treatment plants. Data included
observations relative to filter depth, hydraulic loading, organic load-
ing, recirculation ratio, and wastewater temperature. The equation
which they reported was
Lea = 0.31 Lo/'19 (l+D)-°'67 I'0'15 (Q/I)-0-72 q-0.06 (5_1}
in which Lea = final settling tank effluent BOD in Ibs/acre/day
Loa = BOD applied to filter in Ibs/acre/day
(primary settling tank effluent including recircu-
lation if any)
Q = filter hydraulic loading (mgad)
(influent flow and recirculation flow)
I = influent flow (mgad)
D = filter depth in feet
T = wastewater temperature, °C
Note: Q/I = 1 + Rr in which Rr is the recirculation ratio, i.e.,
(recirculation flow)/(influent flow).
Caller and Gotaas reported a multiple correlation coefficient of 0.97A
for Equation 5-1.
To test the validity of Equation 5-1 a total of 329 complete daily cases
in which there were no missing observations were selected from the total
data file. These data included results from both sides of the Chapel Hill
plant. A linear regression analysis was conducted with the aid of a com-
puter. The linear form of the equation was
£n Lea =60+6! in Loa + B2 in (Q/I) + B3 in I + B4 in Q
A term in filter depth was not included as depth was not a variable dur-
ing the Chapel Hill plant experiments. The resulting regression equation
in exponential form is
23
-------
Le = 20.16 Lo °'67 Q°'72 (Q/ir1'37 T'0'69 (5'2)
3. 3.
The multiple correlation coefficient for Equation 5-2 is 0.84.
In Equation 5-1 the exponent 1.19 on Loa indicates decreas ing
BOD efficiency with increasing BOD loading; in Equation 5-2 the
ent 0.67 indicates the opposite relationship. Caller and Gotaas con-
cluded that " ____ the hydraulic (loading) rate did not contribute any
significant effects to BOD removal efficiency." This conclusion was
based on the low value (close to zero) of the exponent on Q in Equation
5-1. On the other hand, the term qO.72 makes a statistically highly
significant contribution in Equation 5-2, based on the Chapel Hill
plant performance. The exponent on temperature derived from Chapel
Hill data implies that temperature is a more important factor in plant
performance than indicated by Equation 5-1. Lastly, Equation 5-2 indi-
cates that increased levels of recirculation are more significant in
improving plant performance than suggested in Equation 5-1.
Another regression analysis was conducted in which terms Lo and Le were
expressed in more conventional filter organic loading units, i.e., Ibs
of BOD/day/acre-foot of filter volume. In addition, the value of Lo was
based on settled raw sewage BOD (SRS-BOD) and not on the mixture of set-
tled raw and recirculated flow. The value of SRS-BOD was calculated on
the basis of the primary settling removal curve presented in Fair, Geyer
and Okun (20) as simulated by the following computer developed relation!
SRS-BOD = INF-BOD (1 - Primary Tank Removal)
and Primary Tank Removal = 3.77 (fp/10) - 18.1 (tp/10)2 + 54.7 (tp/10)3
- 99.2 (tp/10)4 + 103 (tp/10)5 - 55.8 (tp/10)6,
in which tp = detention time in primary tank in hours.
The values of Le and Lo used in the regression equation presented below
(5-3) and in the rational and semi-rational models described later were
calculated as follows.*
Le = 8.34 (Final Effluent BOD5) (Influent Flow)/ (Filter Volume).
Lo = 8.34 (SRS-BOD) (Influent Flow)/(Filter Volume).
The resulting regression equation, in exponential form is,
Le - 9.84 Lo°'86 T'0-95 (l+Rr)-°-8^ Q°'56. (5_3)
The multiple correlation coefficient for Equation 5-3 is 0.82. The ex-
ponents on the terms in Equation 5-3 are different from those of Equation
24
-------
5-2 due to the difference In the way Loa and Lo were computed in each
case.
2. Rational and Semi-Rational Models
a. Rational Models
One of the first rational models for predicting trickling filter perfor-
mance was that developed by Velz (6). After observing the removal of
BOD at various depths in filters, Velz postulated that the BOD removal
in each increment of filter depth was proportional to the BOD remaining,
as can be represented by the simple differential equation
dL/dD = -kxL
which integrates to
Le/Lo - e~klD
in which Le and Lo are settled filter effluent and settled raw wastewater
influent BOD, respectively, and may be expressed in any consistent and
convenient units.* D is the depth of the filter and k^ is the BOD re-
moval rate constant in units of (distance)~1. Most of Velz's observa-
tions were at reasonably constant hydraulic loadings, hence the time the
wastewater remained in the filter was directly proportional to filter
depth.
Rowland (9) recognized that liquid retention time in a filter was a func-
tion of both depth and hydraulic loading. Analyzing the flow of liquid
over spheres, he demonstrated that liquid retention time was functionally
related to hydraulic loading. For BOD removal he used the expression
Le/Lo = e~kt
in which k is a constant in units of (time)"-'-, and t, the time the waste-
water is in the filter, can be represented by
t = C • D/Qn
in which C = a constant related to the geometry of the filter media
n = a constant related to the type of flow over the media,
i.e., laminar, turbulent or mixed.
For laminar flow Rowland determined that n was equal to 2/3; for turbu-
lent conditions, 1/3. It can also be shown that these exponents are
appropriate for laminar and turbulent flow over inclined flat plates.
*In all rational models discussed in this report Lo refers to settled
raw wastewater BOD, calculated as previously described.
25
-------
Rowland (12) also suggested a temperature correction factor for the rate
constant k as follows:
k9
in which 9 = (1.035)
T-20
Rowland's model for removal of BOD in a trickling filter under laminar
flow conditions without recirculation can be expressed as
Le/Lo - exp (-kt*C'D/Q2/3).
(5-4)
Schulze (14) tested Rowland's model with a pilot trickling filter con-
structed of vertical screens and obtained reasonably good agreement.
Eckenf elder (17) modified Rowland's equation to account for a decreasing
amount of active slime surface with increased depth in a filter by in-
cluding an exponent less than one on the depth term. He further modified
the equation to account for a decrease in the ease of removal of the
various wastewater constituents remaining with increasing depths in the
filter, as shown below
Le/Lo = exp (-x) =
+ x + x2/2< + x3/3! + ---- ).
Eliminating all but the first two terms in the series expression, a so-
called retardant form is obtained, i.e.,
Le/Lo = 1/(1 + x). (5-5)
The general effect of the retardant form is shown in Figure 5-2.
Following statistical analysis of performance of stone-media filters,
Eckenf elder proposed the following model:
Le/Lo = l/(l+K-D2/3/Q1/2).
(5-6)
FIGURE 5-2 EFFECT OF RETARDANT MODEL
26
-------
The factor K combines the rate constant and factors related to the geo-
metry of the filter media. A value of 2.5 was suggested for stone-media
filters.
Eckenfelder suggested that recirculation be treated as a dilution of
filter influent. Assuming that filter effluent BOD is equal to Le when
it has passed through either a primary or secondary settling tank, as
illustrated in Figure 5-3, the following expression can be developed".
Lrn = (Lo + Rr Le)/(l + Rr)
(5-7)
in which Lm = BODr, mg/&, of the mixture of settled raw sewage and set-
tled recirculation flow leaving the primary settling tank.

FIGURE 5-3 MIXTURE OF INFLUENT AND RECIRCULATION FLOWS
Substitution of Equation 5-7 in Equation 5-5, yields Le/Lm = l/(l+x).
With some manipulation, the following relation may be obtained.'
Le/Lo - 1/[1 + x (1 + Rr)] (5-8)
in which x = K'Dm/Qn.
It is the writers' belief that models of the type represented by Equation
5-8 merit further development. The effect of specific surface area of
the filter media can easily be included. The effect of turbulence in
enhancing transfer of organics to the slime layers and the effect of
periodicity of wastewater dosage call for further investigation. Never-
theless, further development of the type of models suggested by Rowland
and Eckenfelder seems to offer the best possibility of increased under-
standing of trickling filter performance.
27
-------
An equation in the form of 5-8, in which a temperature correction factor
(Ta) was included, was fitted to the Chapel Hill data using a nonlinear
regression technique. The nonlinear method was selected, as all trans-
forms devised to express the equation in linear form yielded unsatis-
factory results.
The nonlinear program was developed in the Department of Biostatistics,
School of Public Health, the University of North Carolina at Chapel Hill.
Given the form of the function, with its parameters and variables, the
program gives the values of the parameters which minimize the sum of the
squares of the residuals (the residual is the difference between the
observed value of the dependent variable and the value of the dependent
variable predicted by the model of best fit) . The program uses an itera-
tion procedure similar to that described by Nelder and Mead (21). The
same technique was used in fitting Equation 5-11 described later (the
NRC formula).
The nonlinear regression analysis of the modified Eckenfelder model
(Equation 5-8) yielded the following equation of best fit:
Le = Lo/[l + 0.0055(1 + Rr) Q~0-38 T1-79]. (5-9)
Equation 5-9 is not as different from the original Eckenfelder model as ;
might appear at first inspection. If the actual value of T^-79 at 20° C
is included in the constant, the resulting expression is
Le - Lo/[l + 1.17 (1 + Rr) Q~°-38].
b. Semi-rational Models
A well known semi-rational model is the NRC formula developed from ex-
tensive data collected at military installations during World War II
(7). This model is as follows:
E - 1/[1 + 0.0085 (W/VF)1/2] (5-10)
in which E = the BOD removal efficiency of the filter and the final set-
tling tank as a decimal fraction
W = Ibs of settled raw wastewater BOD/day applied to the filter
V = the volume of the filter in acre-feet
F - the filter recirculation factor » (1 + Rr)/(l + Rr/10)2.
It should be noted that W/V is equivalent to Lo as previously described.
Lo in turn is a product of influent flow and settled raw sewage BOD con-
centration. Hence to a certain extent the NRC formula includes factors
related to organic loading, hydraulic loading and recirculation ratio.
The application of the NRC formula for typical domestic wastewater has
28
-------
been questioned as it was developed from data obtained from the treat-
ment of strong military-base sewage.
An expression in the form of Equation 5-10 was fitted to the Chapel Hill
plant data using the nonlinear regression technique previously described.
The resulting equation of best fit was
+ 14.62(Lo/F)°-44 -r1-85]. (5-11)
Another common semi-rational model was developed by Rankin and has been
adopted for use in the Ten State Standards (22) . For plants similar to
Chapel Hill's, Rankin "s method suggests that if the hydraulic loading on
the filter is between 10 and 30 mgad the filter-final settling tank.
efficiency is strictly a function of the recirculation ratio. Actual
hydraulic and organic loadings are not considered.
c . Comparison of the Models
A comparison of the regression Equation 5-3 and the modified forms of
the Eckenf elder model (Equation 5-9) and NRG formula (Equation 5-11) was
necessary to determine which relation provided the best fit to the
Chapel Hill data. Because Equations 5-9 and 5-11 were determined by non-
linear regression methods it was impossible to find a value for the
multiple correlation coefficient for these equations, so that a compari-
son of correlation coefficients was not possible. To make the desired
comparison the three equations were all reduced to the general form
Le/Lo = x by dividing both sides of the equation by Lo.
For Equation 5-3 the result is
Le/Lo = 9.84 Lo"0-14 T~^-^ (1 + Rr)~°'84 Q°'56. (5-12)
A plot of Le/Lo vs x, i.e., the entire right hand side of Equation 5-12,
is shown in Figure 5-4. The plotted observed values of Le/Lo show a
remarkable degree of scatter around the predictive line. The value of
Equation 5-12 as a reliable predictor of daily plant performance is,
therefore, quite dubious. When Equation 5-3 is analyzed, the sum of the
squares of the differences between observed and predicted values of Le
1.142 x 107.
For Equation 5-9, the modified version of the Eckenf elder model, the
Le/Lo = x form is
Le/Lo = 1/[1 + 0.0055(1 + Rr) Q~°'38 T1'79]. (5-13)
A plot of the predicted and observed values of Le/Lo is shown on Figure
5-5. There is no apparent improvement in regard to the reliability of
daily performance predictions based on this model. From the analysis of
Equation 5-9, the sum of the squares of the difference between observed
and predicted values of Le is 1.132 x 107.

Figure 5-5- Scatter Diagram of Predictive Equation 5-13 in a Form Similar to Eckenfelder's
Model.
-------
For Equation 5-11, the modified version of the NRC formula, toe Le/Lo =
x form is
Le/Lo - 1 - 1/[1 + 14.62 (Lo/F)°-44 I'1'85] (5-14)
A plot of the predicted and observed values of Le/Lo is shown in Figure
5-6. Again the scatter of observed values around the predictive line is
substantial. From the nonlinear regression analysis of Equation 5-11,
the sum of the squares of the differences between observed and predicted
values of Le is 1.230 x 107.
It is apparent that none of the filter performance models tested is very
reliable as a predictor of daily plant performance. Also, the sum of
the squared residuals is not sufficiently different for the three models
to indicate that one is superior. All the models are useful in predict-
ing average performance at the Chapel Hill plant over a long period of
time during which operating conditions, daily wastewater flow and tem-
perature are reasonably constant.
In the discussion of the effects of individual variables following, some
general ideas are presented on how the reliability of filter performance
might be enhanced in new designs.
3. Effect of Variables on Performance
Analysis of regression Equations 5-3, 5-9, and 5-11 as regards the effect
of variation in individual variables, i.e., organic loading (Lo), hydrau-
lic loading (Q), recirculation ratio (Rr), and temperature (T), provides
some insight into relative importance of the variables as related to
filter-final tank performance. Such an analysis was conducted using
Equations 5-12, 5-13, and 5-14, in the manner described below.
In each of the three equations the values of the several variables were
held constant at the mean value of the respective variable during the
329 cases in the experimental program. The variable under examination
was then changed incrementally and the effect on BOD remaining (Le/Lo)
was calculated.
Mean values of the 329 experimental cases are as follows
Lo = 850 Ibs BOD/day/acre-foot
T = 21.2° C
(1+Rr) = 3.53
Q =15.93 mgad (influent flow + recirculation flow)
I =4.43 mgad (influent flow).
1) j-fjgctL_°-f. Organic Loading, Lo
Using the values above for all variables except Lo, the several equa-
tions reduce to the following forms:

NRC Formula.
-------
Le/Lo = 0.874 • LcT0'14.
Equation 5-13, nonlinear regression model of modified Eckenf elder-type
equation —
Le/Lo = 0.383, i.e., organic loading has no effect.
Equation 5-14, nonlinear regression model of modified NRC equation —
Le/Lo = 1 - 1/(1 + 0.0362 Lo0'44).
The calculated effects on Le/Lo resulting from variation in Lo are shown
in Table 5-3 and on Figure 5-7.
As can be seen the three models predict entirely different effects as a
result of variations in organic loading. The writers are inclined to
favor the results produced by Equations 5-12 or 5-13 over those of Equa-
tion 5-14. As Equation 5-12 was developed with unbiased linear regress-
ion techniques it may be closest to the truth. The lower removals at
low organic loadings predicted by Equation 5-12 may possibly indicate
that the slime layers in the lower section of the filter were receiving
too little organic material to maintain the same adsorptive capacity as
slime layers located higher in the filter.
2) Effect of Temperature
The three equations reduce to the following forms in terms of tempera-
ture, T, when all other variables are held constant at mean values:
Equation 5-12, linear regression model —
Le/Lo - 6.27 T~°'95.
Equation 5-13, nonlinear regression model of modified Eckenf elder-
type equation —
Le/Lo = 1/(1 + 0.0067 T1'79).
Equation 5-14, nonlinear regression model of modified NRC equation —
Le/Lo = 1 - 1/(1 + 195.6 I"1-85).
The calculated effects of Le/Lo resulting from variations in temperature
are shown in Table 5-4 and on Figure 5-8.
As can be seen in Figure 5-8, all three models show a similar and pro-
nounced effect on filter-final settling tank efficiency due to changes
in wastewater temperature. The effect may be partly due to a gradual
change in activity of filter biota with temperature. On the other hand,
it was observed that reasonably high efficiency was maintained even

after wastewater temperatures had declined in the fall. Furthermore,
lower efficiences typical of winter operation often persisted after
wastewater temperatures had significantly increased in the late spring.
Inspection of the filters revealed that lower efficiencies were coinci-
dental with the accumulation of inert humus-like material in the filter
media. This accumulation appeared to be related to the density of the
filter fly larvae populations in the filters (23) and was rapidly dis-
lodged with the reappearance of larvae in the late spring. The enhance-
ment of filter performance during periods of increased larval activity
has also been noted in Britain (24). Although all of the predictive
equations analyzed indicate a pronounced temperature effect, the fact
that changes in filter efficiency lag significantly behind the changes
in wastewater temperature is not accounted for. This effect partially
accounts for the high degree of scatter in observed and predicted values
of Le/Lo.
One might speculate that the predictability of filter performance, and
perhaps performance itself, could be enhanced with the use of filter
media designed to minimize the possibilities for the accumulation of
humus -like materials.
3) Effect of Hydraulic Loading
With all variables except hydraulic constant at mean experimental levels,
the three equations reduce to the following forms:
Equation 5-12, linear regression model —
Le/Lo - 0.073 Q°-56-
Equation 5-13, nonlinear regression model of modified Eckenfelder-
type equation —
Le/Lo - 1/(1 + 4.573 Q"°'38).
Equation 5-14, nonlinear regression model of modified NRC equation—
Le/Lo = 1 - 1/1 + 0.686, i.e., hydraulic loading has no effect.
The calculated effects on Le/Lo resulting from variations in hydraulic
loading are shown in Table 5-5 and on Figure 5-9.

It is obvious that hydraulic loading has a significant effect on filter-
final settling tank performance. The apparent zero-effect in Equation
5-14 is simply an artifact of the model, i.e. , no Q term is directly
included in the model.
4) Effect of RecirculationRatio
An increase in recirculation ratio (Rr) also increases the hydraulic
loading (Q). Assuming a constant influent flow (I) the effect of changes
in the recirculation ratio may be analyzed by making a simple algebraic
transformation in the equations as outlined below:
Rr = recirculation flow (Rf)
influent flow (I)
or Rf = Rr I
Q = Rf + I = Rrl + I = 1(1 + Rr).
In Equations 5-12 and 5-13, the terms Rr and Q are in the form (1 + Rr)xQy
which is seen to be equivalent to (1 + Rr)x LY or (1 + Rr)**? IX. With all
variables with the exception of Rr held constant at the mean experimental
levels, the three equations reduce to the following forms:

-------
The beneficial effect of recirculation is clearly apparent in the above
analysis. AH models tested yield an improved removal with increasing
recirculation ratios. Equation 5-13 produces the greatest increase in
efficiency with increased recirculation. Equation 5-14 is the least
sensitive. The unbiased linear regression model (Equation 5-12) more or
less parallels Equation 5-13. These results indicate that fairly high
recirculation ratios, i.e., at least equal to 3.0 and possibly higher,
provide significant improvements in filter-final tank removal efficiency.
This is true even though higher recirculation flows result in higher
hydraulic loading, which considered alone, with recirculation ratios
constant, tends to result in lower efficiencies.
G. PILOT PLANT STUDIES OF TWO-STAGE FILTRATION
1. De_s_cripjtion_ of Pilot Trickling Filters
Two pilot trickling filter plants were constructed during 1966 prior to
the initiation of the work reported here. Two additional trickling
filter pilot plants were constructed during the course of this study. The
plants were designed to treat raw Chapel Hill sewage which had passed
through the main plant bar rack, a degritting chamber, and a fine bar
rack to remove stringy solids which would tend to clog the small pumps
and pipes in the pilot plant. Influent to the pilot plant was delivered
through a 2-inch plastic pipe at a flow rate substantially in excess of
pilot plant requirements. Excess flow was wasted. The required amount
of pilot plant influent was delivered to the operating units by means of
a variable speed pump with B.C. motors regulated by silicon controlled
rectifiers. Flow to each of the pilot units was proportioned with the
use of an overhead rotating distributor discharging into a circular dis-
tribution box with four equal radial sectors. Flow was by gravity from
the distribution box to the primary settling tank of each pilot plant.
Each pilot plant unit consisted of a primary settling tank, a trickling
filter, and a final settling tank. Recirculation was provided around
the filters through the primary settling tank. A general flow diagram
of a single pilot plant unit for single-stage filtration operation is
shown in Figure 5-11.
The sizes of the settling tanks and filters were selected to provide de-
tention time and, in the case of the filters, a hydraulic loading about
the same as experienced in the main plant at a flow rate of 3 mgd. As
the pilot settling tanks were not as deep as the main plant units, the
surface overflow rate in the pilot units was substantially less than
those in the main plant. All settling tanks were equipped for hydro-
static sludge removal.
The filters were designed to operate under conditions similar to those
of the main plant filters. A filter diameter of four feet was selected,
this being considered reasonably safe for minimizing wall effects. Con-
ventional clay tile filter underdrains were used. Filter media depth

was fixed at 4'0". Inner and outer walls of the filters consisted of two
vertical concentric sections of Araco steel pipe, six feet long and 48
and 54 inches in diameter respectively. The annular space between the
inner and outer pipes provided insulation to reduce heat loss during cold
weather operation. Filter media was granite stone selected to meet the
specifications of the N. C. stream pollution control authorities requir-
ing that it pass a 3.5" screen with less than 75% passing a 2.5" screen.

On the basis of an influent BOD of 180 mg/£ and 35% removal in the pri-
mary settling tanks, the organic loading on the filters calculates to be
approximately 1500 Ibs BOD per acre-foot per day.
Early in the experimental work with the trickling filter pilot plants all
four pilot plant units were found to provide comparable performance under
identical loading conditions.
2. A Comparison of Single- and Two-Stage Operation with Pilot Trickling
Filters
Various authors and groups (4, 7, 8, 25, 26) have presented information
suggesting that it is economical to utilize two-stage trickling filtra-
tion. Two-stage or series operation has been indicated to provide a
higher degree of treatment than a single filter of equal volume. The
substantiation of these claims for a typical domestic waste such as
Chapel Hill's would have significant implication for the designer of any
treatment plant in which more than one filter was necessary because of
mechanical considerations or required by design or regulatory standards.
Because of the flow control problems in the Chapel Hill main plant, single-
versus two-stage experiments were conducted in the pilot trickling
filter units. The mode of operation was selected to be similar to that
which would occur in the main plant if all influent flow was treated
through one primary tank, then through one filter with recirculation
through the primary. Effluent from the first stage filter would be passed
through the secondary primary tank, which, in such case, would be acting
as an intermediate settling tank. Wastewater would then pass through
46
-------
the second stage filter with recirculation directly around the filter.
Second stage filter effluent would pass through the secondary clarifiers
prior to discharge.
Three of the pilot trickling filter units were operated as shown in the
flow diagram in Figure 5-12 during the period from May 16, 1972 through
July 13, 1972.

-------
During the single-stage versus two-stage filtration experiments, the in
fluent flow to the single-stage unit was held at 1.2 gpm and the recir-
culation flow was maintained at 2.4 gpm. Influent flow to the two-stage
unit was set at 2.4 gpm. This is double the flow to the single-stage
unit as the objective of the experiment was to estimate the effect of
converting the Chapel Hill plant to two-stage operation in which case the
entire plant influent would pass in sequence through the two filters
rather than being split into equal portions for single-stage treatment
through parallel units. Recirculation flow around each of the filters
in the two-stage unit was held at 2.4 gpm, the same as in the single-
stage unit. The decision to hold the recirculation flows to 2.4 gpm in
the two-stage pilot unit was based on the fact that recirculation pumping
capacity in the main plant is limited and if the main plant were convert-
ed to two-stage it seemed unlikely that the pumping capacity would be in-
creased. With the recirculation flow as described the recirculation
ratios were 2.0 in the single-stage pilot unit and 1.0 in the two-stage
unit.

These loadings and detention times correspond to normal values in full
scale high rate trickling filter plants treating typical domestic sewage.
The organic loading on the filters was calculated on the basis of Ibs
of settled raw sewage BOD per day per acre-foot of filter volume. BOD
removal in the primary settling tank unit was estimated to be 35 percent
in the single-stage unit and 30 percent in the primary tank of the two-
stage unit. Estimated average organic loading on the filters during the
course of this experiment was as follows:
48
-------
Single-stage Filter 1500 Ibs BOD/day/acre-feet*
First Filter in Two-Stage Unit 3200 Ibs BOD/day/acre-feet*
Second Filter in Two-Stage Unit 1300 Ibs BOD/day/acre-feet**
*settled raw sewage BOD
**intermediate settling tank effluent BOD
The organic loadings on all filters, both single- and two-stage, were
within the range normally observed for high rate trickling filters treat-
ing domestic wastewater.
During the single- versus two-stage filtration investigation, samples
were taken each half hour with a multitube sampling pump controlled by
a timer. Samples were taken of influent and final effluent from the
single-stage unit. Samples of influent, first stage effluent (inter-
mediate settling tank effluent) and second stage effluent (final settling
tank effluent) were obtained from the two-stage unit. Daily composite
samples were obtained every Tuesday, Thursday, and Sunday during the
experimental period. The daily sampling started at 8 a.m. and termi-
nated at 8 a.m. the following morning at which time the accumulated sam-
ples were taken to the laboratory for analysis. During collection, the
samples were accumulated in plastic jerry cans and stored at a tempera-
ture of 4° C. All samples were analyzed for suspended solids, organic
carbon and BOD. A summary of the results of the investigation is shown
in Table 5-8.

These results indicate a clear advantage for two-stage filtration as
compared with the more conventional single-stage process. As indicated
in Table 5-9 in the following part of this section, the improved effi-
ciency cannot be accounted for by the greater detention time in the final
49
-------
settling tank in the two-stage unit. The economic advantage of two-stage
filtration may be illustrated by way of an example based on the experi-
mental results.
Using the mean BOD removals found for single-stage filtration and assum-
ing a 35 percent removal of BOD in the primary settling tank, an appro-
priate constant may be determined for the NRC formula.
From the formula for the overall efficiency of two processes in series
the required efficiency of the second stage process can be calculated if
the overall and first stage efficiencies are known. From
Ep + Ef (1 - Ep)
one obtains
Ef = Eoa - Fp/(l - Ep) (5-15)
in which
E0a = overall efficiency
Ep = primary settling tank efficiency
Ef = filter-final settling tank efficiency.
Substituting the assumed value for Ep and the observed overall single-
stage filtration efficiency for Eoa
Ef = 0.798 - 0.3507(1 - 0.350) = 0.69 (69%).
If 69% is accepted for filter-final settling tank efficiency under load-
ings as maintained in the single-stage filtration pilot plant, a new
constant term can be obtained for the NRC formula which will be in accord
with the calculated efficiency.
From
Ef =!/[!+ C1(W/VF)°-5]
with rearrangement one may obtain
Cl = (1 - Ef)/[Ef(W/VF)0-5].
The value of W/V from the single-stage experiments is 1500 Ibs settled
raw sewage BOD per day per acre-foot. The value of F for the recircu-
lation ratio of 2.0 is 2.08. Therefore the calculated value of C± re-
quired for NRC formula agreement with observed results is
G! - 1 - 0.69/0. 69(1500/2. 08)°'5 = 0.0167.
From the results of the experimental program it may be assumed that in
a plant with two equal sized filters operating in parallel at loadings
50
-------
equal to those in the pilot plant, overall BOD removal efficiency
might be increased from 79.8% to 87.2% by converting to series operation
without change in the size of the various units. On the other hand, if
the same increase in efficiency is to be obtained by the addition of
single-stage filters, the required increase in filter volume may be esti-
mated using the NRG formula. The single-stage filter-final settling
tank efficiency required for an overall efficiency of 87.2%, given that
the primary tank removal is 35%, may be calculated using Equation 5-15
as follows:
Ef = (0.872 - 0.350)/(1 - 0.650) - 0.80 (80%).
As the total Ibs of raw settled BOD (W) applied to the filters has not
changed, an estimate of the increased single-stage filter volume may be
obtained by calculating a value for W/V which will provide the required
removal and comparing this value with 1500 (the single-stage filter load-
ing that resulted in an overall removal of 79.8%). To calculate the
required value of W/V for 80% filter-final settling tank efficiency the
NRC formula may be rearranged as follows:
W/V2 - [(1 - Ef)(F)°-5/Ef • Cx
and solving for W/V2 for an 80% filter-final settling tank efficiency
W/V2 - [(1 - 0.80)(2.08)°'5/0.80 * 0.0167]2 - 445.
As W is a constant, i.e., the total Ibs of settled raw BOD applied to
the filter has not changed, it can be seen that for overall efficiency
of 87.2%, W = V2 x 445 = V x 1500. Therefore, V2 = V • 1500/445, i.e.,
the volume of single-stage filters required by the modified NRC formula
for the desired improvement in removal is over three times the original.
The lack of reliability of the NRC formula and other mathematical models
for predicting trickling filter performance has been demonstrated earlier.
The use of any formula in calculations such as those above may be ques-
tioned. Regardless of formula deficiencies, the significant improvement
which can be obtained in overall plant performance by operating trickling
filters in series has been demonstrated in the pilot plant investigation.
In most trickling filter treatment plants, at least two filters are pro-
vided. A design which provides for stage operation of the filters will
add slightly to the initial plant cost, but the cost of adding additional
single-stage filter volume to produce an equivalent efficiency will be
substantially greater.
3. Rationale for Improved Efficiency in Two-Stage Filtration
The improved removal of BOD in two-stage filtration may result from the
fact that as the hydraulic loading on a filter is increased the actual
detention time of the wastewater in the filter does not proportionately
decrease. If it is assumed that both laminar and turbulent flow condi-
tions exist in the flow over filter, media it is not unreasonable to
51
-------
assume that detention in the filter is roughly proportional to D/Q '
(as implied in Eckenfelder's modification of Rowland's equation). Table
5-9 was developed to illustrate the relative effect on filter detention
time of variations in D and Q.

As Table 5-9 shows, doubling the hydraulic loading does not halve the
detention time. In the pilot plant experiments the hydraulic loading on
the single-stage unit was 3.6 gpm which included 1.2 gpm of influent
flow and 2.4 gpm of recirculation flow. Relative detention time in this
unit can be calculated as [4/(3.6)0-5](1 + Rr), where Rr - 2.0. The re-
sult is 6.31. The term (1 + Rr) must be included as the water actually
passes through the filter an average of (1 + Rr) times. In the two-stage
pilot plant the hydraulic loading on each stage was 4.8 gpm which in-
cluded 2.4 gpm of influent flow and 2.4 gpm of recirculation flow. The
total depth of filter media in this case was 8 feet. The total relative
detention time in the two-stage unit is [8/(4.8)°-5](1 + 1) or 7.29. If
the recirculation ratio has been maintained at 2.0, as in the single-
stage unit, the relative detention time in the two-stage unit would have
been 8.43.
Increasing the specific surface area of filter media affects the time
of liquid detention in a filter exactly the same as decreasing the hy-
draulic loading in the same proportion as the specific surface area is
increased. For example, doubling the specific surface area while the
areal hydraulic loading remains constant halves the actual liquid flow
over each unit of media surface. With detention time the proportional
to 1/Q°'5, detention time is increased by a factor of 1.41.
52
-------
It can be seen that two-stage filtration with two filters of equal depth
is comparable to filtration through one filter of twice the depth as the
stage filters, i.e., the liquid detention time in the filter is doubled.
In addition, increasing the specific surface area of the filter media is
analogous to decreasing the hydraulic loading as it affects detention
time. The overall effect on liquid detention time due to filter depth,
recirculation ratio, and specific surface area of filter media is illus-
trated in the following, rather extreme examples:
Case 1. Influent flow 1 mgd; filter area 0.25 acres; filter depth 4
feet; no recirculation; relative specific surface area of
filter media - 1. Q = 1/0.25 = 4 mgad.
Relative Detention Time = D/QO-5 = 4/4°-5 = 2.0.
Case 2. Influent flow 1 mgd; filter area 0.05 acres; filter depth 20
feet; recirculation flow 1.2 mgd; relative specific surface
area of filter media = 2^.
Q = (1 + 1.2)/0.5 = 44 mgad - this is the maximum hydraulic
loading listed for high rate filters in WPCF Manual of Practice
No. 8 (4).
Relative Detention Time = D/(Q/2)°'5(1 + Rr)
20/(44/2)°-5(l + 1.2) = 9.37.
Factors other than liquid detention time can have significant effects on
filter performance. Nevertheless, implications drawn from the two-stage
pilot filter results and the detention time calculations above indicate
the need to re-examine conventional design criteria which have led to
shallow filters operated at relatively low hydraulic loadings and re-
circulation ratios.
H. ANALYSIS OF MAIN PLANT FINAL SETTLING TANK PERFORMANCE
At the Chapel Hill plant filter effluent contains a large fraction of
suspended solids which are so finely divided that they do not settle
well at the overflow rates or detention times typical for the secondary
clarifier. In view of this, an analysis of secondary clarifier perfor-
mance was conducted using data collected during various divisions of
influent plant flow, i.e., from a 20-80% division to a 50-50% division.
Final settling tank daily average detention times varied from approxi-
mately 1.3 hours to 6 hours and overflow rates from approximately 300
gpd/ft2 to 1300 gpd/ft2.
A total of 295 observations of trickling filter effluent and final set-
tling tank effluent were analyzed and the following equations were ob-
tained by regression analysis techniques:
For BOD removal: ,,
Final effluent BOD = e°'84 (TF - BOD)U'6bb qO-521 (5_16)
53
-------
For suspended solids removal: ,, __.
Final effluent SS » 60-83 (TF-BOD)0'668 Q°'521
(5-16)
in which TF - BOD refers to filter effluent BOD; TF - SS, to filter
effluent suspended solids.
Equation 5-16 had a multiple correlation coefficient of 0.85; Equation
5-17, of 0.84.
Plots of Equation 5-16 and 5-17 are presented in Figures 5-13 and 5-14
respectively.
The similarity of the equations for final effluent BOD and suspended
solids implies that a single equation would be satisfactory for both
parameters. Such equations are given below, one in terms of tank over-
flow rate and one in terms of detention time:
Final eff. BOD or SS - 0.092(TF-BOD or SS)2/3 (Qo)1/2 (5-18)
in which Qo = overflow rate in gpd/ft2 and
Final Eff. BOD or SS = 3.9(TF-BOD or SS)2/3 (Dt)"1/2
in which Dt = final settling tank detention time in hours.
(5-19)
Table 5-10 below gives values of final effluent BOD and SS for various
values of overflow rate and detention time corresponding to typical
values of filter effluent BOD or suspended solids.

Using the results in Table 5-10 and cost information for various sized
settling tanks it is possible to make some interesting estimates. For
example, if, for a plant of 1 mgd and influent BOD of 200 mg/fc, the
filter effluent has a BOD of 70 rag/£, the predicted final effluent BOD
for a settling tank overflow rate of 1000 gpd/ft would be 49 mg/£.
Overall plant removal would be 75.5%. Based on cost information sup-
plied by Black & Veatch (5) the 1971 construction cost of a single final
settling tank would be about $42,000. If the surface area of the final
settling tank were doubled the overflow rate would be 500 gpd/ft2 and
the predicted final BOD would be 35 mg/& for an overall plant removal of
82.4%. The 1971 construction cost of the larger final settling tank,
again based on Black & Veatch, would be about $55,000. The incremental
cost of $13,000 is quite reasonable for the projected increase in effi-
ciency. The cost of achieving a similar improvement by adding to other
units in a trickling filter plant, i.e., the primary settling tank, the
filter, or the recirculation capacity, would be substantially greater.
57
-------
I. CONCLUSIONS REGARDING OPERATION OF EXISTING TRICKLING FILTER PLANTS
Often there is little that can be done to improve the operation of an
existing trickling filter plant unless the plant is not being operated
properly. Occasionally, however, plants are designed with sufficient
flexibility to allow modifications in operating procedures which can
improve treatment results.
Recirculation - Some plants may be provided with ample recirculation
capacity, but fail to utilize it. As indicated in Figure 5-10 recircu-
lation ratios up to 3.0 can add significantly to plant performance.
High recirculation ratio and consequent high hydraulic loadings also
help control the growth of psychoda flies during warm weather. On the
other hand, low recirculation ratios may impair operating efficiency and
result in conditions favorable to the prolific growth of psychoda flies
with attendant nuisance conditions.
At a few plants recirculation flow is drawn from a point downstream of
the final settling tanks. This means that both influent base flow and
recirculation flow passes through the final tank. In such cases the
tank must be designed to handle the higher resulting hydraulic loadings
and, consequently, may be quite large. If the point of recirculation
suction is changed to a location ahead of the final tank there will be
little or no effect on the performance of the trickling filter as a
unit, but the performance of the final tank will be significantly im-
proved at the lower hydraulic loading. For example, if the final tank
hydraulic loading was 800 gpd/ft^ with recirculation flow through the
tank at a recirculation ratio of 1.0, predicted final effluent BOD and
SS according to Table 5-10 would be 48 mg/£ if the filter effluent BOD
and SS were 80 mg/£. Taking recirculation flow ahead of final tank
would reduce the hydraulic loading to 400 gpd/ft^ and predicted final
effluent BOD or SS would be 34 mg/£ - a substantial improvement in per-
formance.
Experiments were conducted during this investigation as to the effect of
the point of recirculation return, i.e., ahead of the primary settling
tank or directly ahead of the filter. Recirculation through the primary
tank showed a very slight advantage. If the primary tank is overloaded,
e.g., a detention time of one hour or less with recirculation flow pass-
ing through the tank, there may be some advantage in direct recircula-
tion. However, the advantage of direct recirculation, under such con-
dition, has not been verified during this study. If prechlorination is
not possible, recirculation of filter effluent through the primary tank
freshens stale influent sewage and helps prevent odors.
Two-Stage Filtration - If a trickling filter plant has been designed to
permit either single- or two-stage operation of the filters, the two-
stage method should be used to the greatest extent possible. As has
been indicated in this investigation, two-stage operation will result in
58
-------
significant improvement in plant performance as compared with single-
stage filtration.
Supernatant Return - The quality of anaerobic digester supernatant and
its method of return to the plant flow units can have a significant ef-
fect on plant performance. Intermittent, high rate, return of superna-
tant from a mixed digester will have a very deleterious effect on plant
performance and on the appearance of the final effluent. On the other
hand, the continuous return of supernatant from an unmixed secondary
digester during periods of low plant flow, e.g., during the night, will
have little effect on plant performance. For these reasons, when two
or more digesters are available, one unit should be used as a secondary
to provide conditions for separation of sludge and supernatant. The
secondary unit should not be mixed or heated unless the heating system
does not contribute to tank turbulence. Supernatant should be returned
to the head end of the plant.
J. CONCLUSIONS REGARDING PLANT UPGRADING WITH MINOR ADDITIONS
Recirculation - If no provision for recirculation has been made in the
original design, its addition at a later date may be difficult. On the
other hand, the addition of a recirculation well with vertical shaft
pumps may be possible. As has been shown, recirculation will have a
beneficial effect on plant performance.
Frequently the recirculation capacity provided in original design does
not permit operation at recirculation ratios much above 1.0. In such
cases consideration should be given to increasing recirculation capa-
city. It is often possible to substantially increase recirculation flow
by increasing pump impeller diameter and motor horsepower.
In cases where recirculation is added or increased it will be necessary
to carefully check the hydraulic capacity of the various units which
will be affected. Particular attention should be given to the capacity
of the filter distributor and underdrainage system. Distributor capa-
city can often be increased by increasing the size of the distribution
orifices, provided the distribution arms can carry the extra flow with-
out too high a water level in the central column. The underdrainage
system must have sufficient capacity to carry the extra flow without
impairing filter ventilation.
Two-Stage Filtration - Often two or more filters exist at a plant but no
provision exists for two-stage operation. In such cases, two-stage
operation will result in improved performance provided the units have
hydraulic capacity to handle the flow. For example, conversion to two-
stage operation at Chapel Hill will result in a 33 percent increase in
flow through the filters provided the recirculation flow is not in-
creased. In all cases plant hydraulics must be carefully analyzed be-
fore attempting any modification to provide two-stage operation. If
hydraulic problems are encountered the expedient remedy may be to reduce
recirculation flow. When an existing plant is designed for single-stage
59
-------
operation only, it will be necessary to alter some structures, piping
and valving to channel the effluent from the first stage units to the
second stage units. A flow control system to equalize flow from first
to second stage units with plant influent flow must also be provided.
Final Settling Tanks - As indicated in Part H, additional final settling
tank capacity will significantly improve overall plant efficiency for
relatively minor capital costs.
K. CONCLUSIONS AS TO THE DESIGN OF MAJOR ADDITIONS OR NEW PLANTS
In the selection of a biological treatment process for a new facility
a number of cost and operating factors must be considered. If removal
of 80 or 85 percent of BOD and suspended solids, during summer months,
will meet requirements, the normal single-stage high rate trickling
filter process, designed at conventional loadings, is an attractive alter-
native. Operating costs are relatively low, the system recovers quickly
from shock loads and operation is fairly simple. On the other hand,
if 90 percent or more removal is required, the activated sludge process
is commonly selected. Although this process is more easily upset and
requires a higher level of operating skill, it will provide 90 percent
or greater efficiency when operating properly.
Smith (27) has reported the total annual cost of various types of treat-
ment plants. Some of these data, adjusted to an ENR Cost Index of 1600,
are tabulated below:
TABLE 5-11
COSTS OF TRICKLING FILTRATION AND ACTIVATED SLUDGE PLANTS ADJUSTED

5 15.2 19.8
10 12.6 16.8
20 10.6 14.0
100 8.5 9.7
Obviously, the trickling filter process has the economic advantage,
particularly for small and medium sized plants. If the efficiency of
the trickling filtration process could be upgraded to compare with that
of activated sludge, it would be a very attractive alternative in many
situations.
Frequently, the design engineer faces the problem of obtaining a plant
efficiency of 90 percent or more where a trickling filter plant is al-
60
-------
ready in existence. As illustrated in the following example, he might
consider the construction of additional plant units, similar to those in
existence.
Given: A high rate trickling filter plant with an influent flow
of 1 mgd and BOD of 166 mg/&, in which the primary tank
removes 35 percent of the BOD and the filters and the
final tank removes 69 percent of the remaining BOD for
an overall plant removal of 80 percent at a temperature
of 22° C. The filter has an area of 0.25 acres and a
depth of 4 feet. The recirculation ratio is 2.5.
(Filter efficiency is based on Equation 5-12).
Required: An overall plant removal of 90 percent.
Solution: Assume the settling tanks are not overloaded and that
required efficiency is to be obtained by providing
additional filters.
The required efficiency of the filters and final settl-
ing tanks must be 85% for an overall plant efficiency
of 90%.
[Eoa = 1 - (1-E1)(1-E2); 0.90 = 1 - (1-0.35)(1-0.85) =
0.90].
Equation 5-12 may be rearranged to solve for filter volume as follows:
Le/Lo = 9.84 (W/V)'0'14 T~°'95 (l+Rr)~°-28 (If/V/D)0'56
in which W = Ibs. settled raw BOD/day
V = filter volume (acre-feet)
If = settled sewage influent flow (mgd).
Solving for V
V = [(Lo/Le) 9.84 W0- 14T-°- 95(1+Rr)-0. 28If 0.5^0. 56] 2. 38.
Under the given conditions,
V = [ (Lo/Le) 0.309]2*38
and for a filter-final tank efficiency of 85% the required filter
volume is 5.59 acre-feet.
The cost of the original filter volume (1.0 acre-feet) estimated from
Black & Veatch data (5) adjusted to an EPA Wastewater Treatment Plant
Construction Cost Index of 173 is $160,000. For an additional filter
volume of 4.59 acre-feet, the added cost will be 4.59 x $160,000 or
61
-------
$734,000. Attendant recirculation facilities for the new filters will
add another say, $250,000, for a total additional initial cost of
$984,000. Ammortizing these costs over 25 years at 6% interest plus an
additional $20,000 per year for operation gives a total annual cost at-
tributable to the new filters of
$984,000 x 0.0782 + $20,000 = $97,000/year.
If a second filter of the same size of the original filter is added, as
a second stage unit and its relative efficiency, compared with the first
stage filter, is the same as found in the pilot plant experiments re-
ported previously (i.e., the second stage pilot filter was 93% as effi-
cient as the first stage unit in terms of BOD), the overall plant effi-
ciency would be,
En. - 1 - (1-0.35)(1-0.69)[1-(0.93)<0.69)] = 0.928, (92.8%).

In this case the additional cost for one filter is $160,000 plus say,
$60,000 for recirculation and $5,000 per year for additional operating
costs. The total annual cost over 25 years at 6% interest would be,
$220,000 x 0.0782 + $5,000 = $22,000/year.
Obviously two-stage filtration provides a more economical alternative.
The estimated removal for the two-stage system may be optimistic, how-
ever, if additional final settling tank capacity were added it seems
safe to say that the reliable average BOD removal efficiency would be
at least 90 percent.
Chemical treatment of filter effluent at Chapel Hill described in another
report (*), indicates that over 90 percent of BOD, SS and phosphorus can
be removed with alum dosages of about 175 mg/£. Allowing $55 per ton for
alum, $100,000 for the initial cost of chemical storage, handling and
feeding equipment, $150,000 for sludge disposal facilities, $100,000 for
additional final settling tanks, and $10,000 per year for other additional
al operating costs, the total annual cost per mgd is estimated to be
$50,000.
The relations developed to predict final settling tank performance
(Equations 5-18 and 5-19) clearly indicate the benefits of designing for
lower surface loadings. Although these equations are only valid for
final tanks following single-stage filtration it is reasonable to sup-
pose that low surface loadings would provide similar improvements follow-
ing two-stage filtration. When chemical precipitation using aluminum
or iron salt for phosphorus removal is required, or likely to be re-
quired in the future, low surface loadings will significantly improve
overall results. Performance applying liquid alum to final settling
tank influent at Chapel Hill was greatly enhanced when final tank sur-

face loadings were reduced to values less than 600 gpd/ft^. Based on
the probability that many plants will be required to remove phosphorus,
coupled with the observed improvement in plant performance at low final
tank loading with or without chemical treatment, it is recommended that
design criteria for new or additional final settling tanks for trickl-
ing filter plants be based on a surface loading of 500 gpd/ft^. Since
chemical treatment will be required at many plants it is suggested that
structures be provided to facilitate the addition of rapid mixing and
flocculation. Flocculation might be provided in a separate structure
or as an integral part of the final settling tank.
In summary, new or enlarged trickling filter plants should be provided
with the following features:
1. Two-stage operation of filters with provision for interchanging
the lead and secondary filters.
2. Sufficient recirculation pumping capacity to provide a recircu-
lation ratio of 3.0 around both first and second stage filters.
3. Final settling tank surface loadings of 500 gpd/ft2.
4. Provision should be made for the possible future addition of
coagulants such as iron and aluminum salts. In this regard ,
structures designed to facilitate the addition of rapid mixing
and flocculation should be incorporated in the design.
Trickling filter plants designed to the general criteria suggested above
should provide a very acceptable alternative to activated sludge. Per-
formance will be comparable. Total annual cost will be lower while the
traditional advantage of the trickling filter process, i.e., simplicity
of operation and ability to withstand shock loads without long term pro-
cess upset, will be maintained.
The further development of rational theory for trickling filter perfor-
mance offers distinct possibilities for improvements in process effici-
ency and economy. In the section of this chapter describing two-stage
filtration with pilot filters it was implied that current theory, if
substantiated, could lead to the development of deep filters, packed
with a media of high specific surface area combined with non-clogging
properties, operated at high hydraulic loadings and high recirculation.
This type of development might lead to the continuous dosage of waste-
water to the surface of the filter with the elimination of costly rota-
ry distributors.

SECTION VI
ACTIVATED SLUDGE STUDIES
The high-rate trickling filter wastewater treatment plant is generally
incapable of routinely meeting standards of 90% removal of BOD and sus-
pended solids. The filter effluent contains suspended solids which
resist settling and which are removed to only a slight extent in the
secondary clarifier. Since nitrification is rarely achieved in high-
rate filter plants, the effluent from such a plant is characterized by
a high ammonia content (25-35 mg/£ NH4+-N) which exerts an oxygen demand
in the receiving stream.
On the other hand, activated sludge treatment is generally capable of
90% removals of BOD and suspended solids. With appropriate control of
dissolved oxygen, loading, and detention time, activated sludge systems
can be modified to achieve high degrees of nitrification in relatively
short detention times.
Based on such considerations, it would appear that further treatment of
trickling filter effluent by short-term activated sludge treatment could
enhance the quality of the final effluent.
Hagerich (28), Vosloo and Finsen (29), Hansen et al. (30), and the City
of San Buenaventura (31) have reported that activated sludge units have
been used to treat trickling filter effluent. Hagerich (28) reported
overall 96.5% reductions in suspended solids and 96.6% reductions in
BOD. He did not report the detention time of the aeration units al-
though the indication is that it was relatively short. Hansen et al,
(30) report BOD removals of 82% and suspended solids removals of 76%.
These removals seemed to be adversely affected by solids carryover and
storm water infiltration and wash-out. None of the previous investiga-
tions systematically evaluated the most effective design parameters of
optimum activated sludge treatment of trickling filter effluent. The
purpose of the present investigation was to evaluate the utility, de-
sign, operation, and characteristics of activated sludge treatment of
trickling filter effluent.
A. 0.1 GPM ACTIVATED SLUDGE PILOT PLANTS
1. Design and Operation
Five tertiary activated sludge pilot plants (ASPP) each consisting of
an aeration tank and settling tank with air lift sludge return were con-
structed as shown in Figure 6-1. Design parameters are given in Table
6-1. The hydraulic detention time varied from 0.4 hr in Unit 1 to 9.2
hr in Unit 5, and the volume under aeration varied from 7 1 in Unit 1
to 165 1 in Unit 5. The influent to the ASPP was effluent from one of
the Chapel Hill trickling filters. This was channeled into a flow split-
64
-------
ter and fed at 300 mJt/min to each unit. The five settling tanks were of
identical design; thus, the overflow rates and detention times were
identical for each unit. Aeration was provided at such a rate as to
maintain the dissolved oxygen in the aerator above 1.5 mg/A. Sludge was
returned to the aeration unit at a rate of 1000 m&/min, and temperature
was controlled at 25° C in the aeration units.
Since the main plant trickling filters were also being manipulated experi-
mentally by altering the organic and hydraulic loading, the quality of
the influent to the ASPP varied not only with the traditional season and
raw sewage flow but also with the main plant experimental design. The
experimental program of the ASPP was designed to evaluate the effect of
detention time, sludge wasting, pH control, and influent loading on over-
all performance (Table 6-2). Sludge was wasted by withdrawing equal
portions of the mixed liquor three times a day. During periods of pH
control, NaHCO-j was metered into the influent stream in such quantities
that influent alkalinity was increased by about 40 mg/Jl as CaCO-j. This
program was initiated due to the sharp decrease of pH in units exhibit-
ing nitrification. This will be discussed in a subsequent section. It
was anticipated that the small settling tanks would not provide efficient
solids removal. To establish the performance of the units with complete
solids removal as well as evaluate the contribution of solids to the
various quality parameters, all samples were analyzed both uncentrifuged
and centrifuged (10 min @ 2200Xg, International Model UV Centrifuge).
Two-day composite samples were collected automatically three times per
week by pumping equal volumes from the influent line and the overflow
from each settling tank every 30 min into sample containers stored at
3-5° C. They were analyzed for uncentrifuged and centrifuged suspended
solids, volatile solids, total organic carbon, chemical oxygen demand
(COD), biochemical oxygen demand (BOD), methylene blue active substances
(MBAS), and all forms of nitrogen and phosphorus. Mixed liquor grab
samples were analyzed for mixed liquor suspended solids (MLSS) and mixed
liquor volatile suspended solids (MLVSS). Grab samples of the influent
and effluents from the units were analyzed daily for turbidity and pH.
Dissolved oxygen, influent flow rate, temperature, return flow rate,
and settleable mixed liquor solids were determined daily.
Figure 6-2 is a photograph of the units in operation.
2. BOD Removal
As mentioned earlier, it was anticipated that the small settling tanks
would not provide optimum solids removal. Heavy blankets of sludge did
develop but channeling problems prevented return of this heavy sludge
with the air lift sludge return. While sludge was returned, the concen-
tration was not as great as that which remained in the settling tanks.
Thus, large quantities of solids remained in the settling tanks. This
accumulation was greatest in the settling tank of Unit 1 and least in
Unit 5. During periods of active nitrification in the aeration units

and active denitrification with consequent release of nitrogen gas in
the settling tanks, sludge floated to the surface and was carried into
the effluent stream. Thus, the effluent often had a high solids concen-
tration.
Practical activated sludge treatment, of course, requires that the sludge
be readily settleable for return to the aeration unit or wasting. Table
6-3 shows the average sludge volume index (SVI) and mixed liquor suspend-
ed solids (MLSS) in the five ASPP during the eight experimental periods.
Note that, except for period VIII when the system was full of solids due
to the long period of no wasting, the SVI was within the acceptable
limits of a "good" activated sludge (50-100). This suggests that, with
settling tanks more hydrodynamically similar to full scale installation,
substantial solids removal by sedimentation might occur.
Mixed liquor suspended solids, in general, decreased with increased de-
tention time, but the total mass of solids increased with detention
time due to the size of the units. Since all units were fed at the same
rate, loading was highest at the lower detention times. MLSS was gener-
ally highest during periods of highest BOD loading and decreased with
wasting during periods III, IV, and V. The values increased markedly
during period VI following the period of high wasting. During period
VIII, high BOD loading and very heavy solids accumulation in the settl-
ing tank changed the character of the sludge with resultant bulking and
lower than expected MLSS.
The above data regarding SVI and MLSS indicate that an activated sludge
process can be maintained with trickling filter effluent as feed. Hav-
ing established that such a unit will operate, it remains to establish
the treatment capability and size of such a unit process.
Table 6-4 presents the average BOD at various points in the full scale
trickling filter treatment process and of the effluents from the ASPP.
Since the samples included solids, high average BOD values were recorded
in the effluents of the ASPP when there was substantial solids carry
over. The BOD values of the main plant final settling tank effluent are
little different from those of the ASPP influent (trickling filter
effluent); therefore, the main plant final settling tank provided little
BOD removal. Effluent BOD's from the ASPP generally decreased with in-
creased detention time and were substantially lower than influent in all
units for all periods except for Unit 1 in period II. Thus, even with
far from optimum sedimentation, sludge return, and sludge wasting, the
effluent BOD from these tertiary activated sludge units was substantially
lower than normal effluent BOD from the trickling filter plant.
Since it was felt that a full scale activated sludge process would have
substantially lower effluent solids, centrifuged as well as uncentri-
fuged samples were analyzed. Table 6-5 lists the uncentrifuged raw in-
fluent BOD, uncentrifuged and centrifuged values of trickling filter
effluent BOD, and the centrifuged BOD of the ASPP effluents. Having

already established that the final tank accomplishes very little BOD
removal, the uncentrifuged and centrifuged values of filter effluent BOD
give an approximation of the effect of complete solids removal on the
quality of the final main plant effluent. Complete solids removal by
filtration, coagulation, or some other process would indeed improve ef-
fluent BOD markedly. However, passing trickling filter effluent through
the ASPP and removing solids from the effluent decreased BOD to very low
levels. Notice that even with less than 2 hrs. detention (Units 1, 2,
and 3) the effluent BOD was within quite acceptable limits. Longer de-
tention time resulted in effluent BOD values which are similar to those
of natural fresh water in the Piedmont area of North Carolina. While
there was substantial variation in values from unit to unit and period
to period with uncentrifuged samples, there was much less variation with
centrifuged samples. This, of course, indicates that consistent perfor-
mance depends in large part on effective solids removal.
Table 6-6 presents the average per cent removal of BOD from trickling
filter effluent within the ASPP. Removal generally increased with de-
tention time and generally decreased during the period of high wasting.
Since these removals are based on uncentrifuged samples, they are gener-
ally lower during periods when the effluent was high in solids. Also,
since the values in this table are from uncentrifuged samples, these
probably indicate the lowest performance expected by activated sludge
treatment of trickling filter effluent. All are, of course, better than
the removal provided by the conventional final settling tank in the main
plant.
Table 6-7 presents the average removal of BOD within the various ASPP
units with subsequent centrifugation of the effluents to remove solids.
Removals were much greater with centrifugation, as shown in the previous
table. These results, then, represent the highest performance to be
expected within the activated sludge units of various detention times
treating trickling filter effluent. The variation in performance at
various detention times with complete solids removal was much less than
without solids removal. This would again indicate that effective solids
management would allow substantial BOD removal even at the 0.4 hr. de-
tention time.
One of the implicit purposes of any addition to the treatment flow sheet
of the trickling filter process is to increase overall BOD removals to
greater than 90%. Figure 6-3 shows the BOD removal by the main plant
during the eight experimental periods and the additional removal by
activated sludge treatment of trickling filter effluent. These values
are calculated on the basis of uncentrifuged samples. With this lowest
performance measurement, there is generally substantial improvement even
with the short detention time units while the higher detention units
generally provided approximately 90% overall BOD removal.
Figure 6-4 shows the overall BOD removal in the main plant and the addi-
tional removal by the activated sludge units followed by solids removal.

FIGURE 6-5 RELATIONSHIP OF BOD LOADING TO PER CENT BOD REMOVAL
IN ACTIVATED SLUDGE PILOT PLANTS.
-------
All BOD removals are in excess of 93%. Thus, with optimum solids manage-
ment even 0.4 hr. detention consistently may result in greater than 90%
removal.
It has already been shown that the final settling tank in the present
trickling filter plant improves overall removals by only 1-10%. Since
this tank allows approximately 2 hrs. detention, it may be possible to
economically convert it to contain an aeration and settling chamber as
previously reported by Hansen et al. (30). Thus, performance could be
substantially improved at low capital cost.
Figure 6-5 shows the relationship of BOD removal to BOD loading in the
ASPP- These results are based on uncentrifuged samples, but the same
type of relationship holds for centrifuged samples. As expected, BOD
removal increased as loading decreased. This suggests improved trick-
ling filter performance with greater BOD removal would allow better fur-
ther removal in activated sludge units treating trickling filter effluent.
Removals of COD and organic were very similar to removal of BOD in
the ASPP. MBAS reduction in the ASPP averaged 50-75% from trickling
filter effluent with final effluent values of 0.2-0.8 mg/Jl. Phosphorus
removal was nil through the ASPP, but the addition of activated sludge
treatment to trickling filter plants may provide a convenient point for
addition of chemicals for precipitation of phosphorus.
The results of this investigation established that activated sludge
treatment of trickling filter effluent substantially increased overall
BOD, COD, organic carbon, and MBAS removals. Furthermore, very short
detention times were sufficient for substantial improvement. The amount
of the increase was dependent upon the ability to remove solids from the
effluent and carefully control returned sludge and wasting rates. It is
realized that the magnitude of some of the results reported here may be
due to the 25° temperature of the aeration units. Since the main inter-
est of this investigation was to evaluate the effect of detention time
and since the variation in size of the units would cause large variations
in temperature, it was necessary to hold temperature constant. Experi-
ence with samples from short periods when the temperature controllers
were out of order indicates that th<* temperature effect is not as great
as one would might suppose.
3. Nitrification
Most of the nitrogen in the effluent of a typical high-rate trickling
filter plant is in the form of ammonia. Ammonia released into receiving
waters exerts an oxygen demand and serves as an algal nutrient. Incor-
poration of nitrification processes into waste treatment would insure
oxidation of ammonia to nitrate, thus reducing oxygen demand of the ef-
fluent. In addition, oxidized nitrogen in nitrified effluents is amen-
able to removal by denitrification (32).

FIGURE 6-5
RELATIONSHIP OF BOD LOADING TO PER CENT BOD REMOVAL
IN ACTIVATED SLUDGE PILOT PLANTS.
-------
Nitrification is a biological process. The most important genera of
bacteria involved in nitrification are Nitvosomonas3 which oxidizes am-
monia to nitrite, and Nitrobaoter, which oxidizes nitrite to nitrate (see
reviews by Painter, 32; Alexander, 33; and Thimann, 34). These organisms
are obligate autotrophs, requiring inorganic carbon in the form of carbon
dioxide or bicarbonate. During nitrification, acidic products are formed
from oxidation of ammonia and alkalinity is decreased due to consumption
of inorganic carbon; thus, in poorly buffered systems the pH decreases.
The nitrifying organisms are obligate aerobes, requiring an oxygen con-
centration of at least 0.5-0.6 mg/£ (35, 36), with the possible exception
of some marine species reported to operate at much lower oxygen concen-
trations (37). While oxygen concentrations of 1-7 mg/£ are generally
recommended for nitrification (35) it has been observed that nitrifying
activated sludge can become acclimated to semiaerobic conditions (38).
Intimately related to the effect of oxygen concentration is the effect
of loading. Wuhrmann (39) noted in his investigations that considerable
nitrification took place at low (1 mg/£) oxygen concentrations provided
that a low plant load was combined with high sludge concentrations; on
the other hand, no nitrification took place even at 7 mg/£ with high
loading rates. Other investigators (40, 41) have also noted significant
decrease in nitrification with increased loading.
There are a number of ways in which high loading may affect nitrifica-
tion. High loading may result in higher concentrations of inhibitory
compounds in the nitrification unit. Many organic compounds inhibit
nitrification, among them gelatin, some amines, alkaloids, and amino
acids (34). Higher loading could conceivably increase ammonia concen-
tration in the aerator to a level intolerable to nitrifiers. Both Nitro-
somonas and Nitrobacter are inhibited by high levels of ammonia; the
latter, more sensitive, does not develop in many cases until the ammonia
level has been reduced by Nitrosomonas (34). High loading also increases
the concentration of carbonaceous materials which are readily assimilable
by heterotrophic bacteria. It is the opinion of several investigators
that the inhibitory effect of most organic materials on nitrification is
due to their stimulation of rapid-growing heterotrophs which assimilate
the majority of the inorganic nitrogen, making it unavailable to the
slower growing nitrifiers (33, 42). In addition, if high loading neces-
sitates sludge wasting from an activated sludge unit, the removal of the
slow-growing nitrifiers can prevent development of a population large
enough to accomplish nitrification.
Since the nitrifying bacteria are obligately autotrophic, inorganic car-
bon is an essential nutrient for their growth. Thus, nitrifiers may be
limited by availability of inorganic carbon in the same manner as are
algae (43, 44, 45). Little information is available on the effect of
inorganic carbon concentration on the efficiency of nitrification pro-
cesses. In addition, it is difficult to distinguish the relative impor-
tance of inorganic carbon availability because of the common practice,
both in basic and applied investigations, of adding bicarbonate or car-
bonate alkalinity to the feed to control pH (29, 34, 42, 46, 47).
81
-------
The optimum pH for nitrification is currently a controversial topic.
It has been variously reported from pH 6.0 (47) to pH 8.8 (34). Meek
and Lipmann (48) reported the isolation of organisms capable of nitri-
fication at pH 4.1. Wild, Sawyer, and McMahon (49) report that the opti-
mum pH for nitrification by activated sludge is 8.4 with 50% of the maxi-
mum rate occurring at pH's of 7.0 and 9.8. Rimer and Woodward (50), on
the other hand, were unable to maintain nitrification in their activated
sludge system at pH lower than 8.3-8.5. Recent reviews of the effect of
pH on nitrification in soil (33, 51) described instances in which nitrifica-
tion occurred at pH's as low as 4.0-4.5; both reviews indicate the pos-
sibility that there are little known species of nitrifiers adapted to
low pH. Alexander (33) cites studies indicating that some isolates from
alkaline soils have an optimum of 7.8.
Changes in pH may affect nitrification in several ways. pH may affect
essential biochemical reactions, or alter the toxicity of metals or cya-
nide (36, 46). A low pH is also an indication that the alkalinity has
been depleted.
The optimum temperature for nitrification is 30-35 C (34) although nit-
rification can occur over the range 5-40 C (33).
While a number of investigations have been performed on nitrification
processes in wastewater, few studies have been performed on the applica-
tion of the activated sludge process for upgrading trickling filter ef-
fluent. Two previous studies in this category are those of Wild, Sawyer,
and McMahon (49) and Vosloo and Finsen (29).
Vosloo and Finsen (29) investigated application of the activated sludge
process to improvement of a low-rate filter effluent in both batch and
continuous studies over a one-month period. In a continuous feed unit
operated with 17-30 mg/i influent NH3-N, a 2.9 hr aeration period, and a
MLSS concentration of 8000 mg/Jl, an average of 85% of the ammonia was
removed. Further studies performed with an excess of alkalinity in the
form of powdered calcium carbonate showed that oxidation of 1 gm/£ of
nitrogen caused a decrease in alkalinity of 7.15 mg/£. Vosloo and Finsen
found that appropriate batch addition of powdered calcium carbonate main-
tained the pH above 6, allowed nitrification to proceed to completion,
and greatly improved settleability of the sludge.
Wild, Sawyer, and McMahon (49) investigated nitrification in a pilot
activated sludge unit receiving settled high-rate trickling filter ef-
fluent and in laboratory batch studies. Effect of pH, MLVSS concentra-
tion, ammonia concentration, and BOD on nitrification were studied in
batch studies. pH was controlled by addition of sodium hydroxide. From
short-term (3 hr) experiments, the following conclusions were drawn:
1. ammonia concentration does not inhibit nitrification at concen-
trations less than 60 mg/£
2. pH sharply affects rate of nitrification; optimum pH is 8.4
82
-------
3. increases in temperature increase rate of nitrification, in
the range of 5-30 C
4. for a given sludge, with MLVSS concentrations in the range
800-6000 mg/Jl, the time to completely nitrify a given amount
of ammonia per gram of MLVSS is constant under the same
environmental conditions
5. instantaneous increases in BOD concentration over the range
5-110 mg/Jl do not affect rate of of nitrification.
During pilot-plant activated sludge studies at Chapel Hill nitrification
was consistently noted in several of the units, leading to further in-
vestigations on the factors affecting nitrification.
In the following discussion of results from these studies, performance
of the units under the various modes of operation is presented in terms
of ammonia removal, though it must be understood that the ammonia nitro-
gen is not removed but rather converted to oxidized forms — nitrite and
nitrate — during nitrification. The observation that some denitrifi-
cation was occurring in the final settling tanks made it desirable to
express the results in terms of ammonia disappearance rather than in
terms of nitrate increase.
As shown in Figure 6-6, some ammonia removal occurred during all phases
of operation. In general, units with the longer detention times removed
a higher percentage of the ammonia. Of a total of 40 cases (5 units,
8 operational phases) there were 10 cases in which 90% or more of the
ammonia was removed and 6 cases in which 45% or less was removed. A sum-
mary of the average values of several operating parameters, contrasting
these values in cases of high and low removal, is presented in Table 6-8.
From Table 6-8, it is apparent that maximum removals are usually, but not
exclusively, correlated with low influent BOD, long detention time, low
loading, low MLSS, and adequate bicarbonate alkalinity. A cursory exam-
ination of pH would seem to indicate that low pH is also associated with
maximum removal, but the lower pH levels are probably simply an effect
of extensive nitrification.
In order to simplify interpretation of the results obtained under dif-
ferent operating conditions, the amount of ammonia removed as a function
of detention time is presented in Figures 6-7-6-10.
Figure 6-7 shows ammonia removal under conditions of no sludge wasting
and no alkalinity addition. Note that while the influent ammonia concen-
trations are similar, average influent BOD varied from 35-68 mg/&. In
general, ammonia removal was greatest during the phase when influent BOD
was lowest; poorer, during the phases when influent BOD was 60-63.
The effect of alkalinity addition (bicarbonate) on ammonia removal is
shown in Figures 6-8 and 6-9. Under these conditions of no sludge wast-
ing and low (35-36) BOD in the influent (Figure 6-8) alkalinity addition
had little effect at the shorter detention times, but at longer detent-

ion times, the extent of ammonia removal was less when alkalinity was
not added. Since bicarbonate addition serves both to provide inorganic
carbon and to control pH, distinguishing between pH and inorganic carbon
concentration effects is not possible under the conditions of these ex-
periments. During phase 7, without alkalinity addition, inorganic car-
bon concentration in the units was low, as shown in Table 6-9.
Under conditions of high influent BOD (Figure 6-7) effect of alkalinity
addition was not as clear. However, the depression of ammonia removal
under conditions of long detention time and no alkalinity addition was
noted in one case. A comparison of pH and inorganic carbon concentra-
tions is shown in Table 6-10. The drastic drop in pH to 4.7 in Unit 5,
phase 1, may account for the poor performance as compared to the same
unit during phase 8 (Figure 6-9). The pH in the unit remained above pH
6 during phase 8, despite low inorganic carbon concentrations; the reason
for this phenomenon is not known.
The effect of sludge wasting on the units is shown in Figure 6-10. On
the whole, moderate sludge wasting did not affect nitrification perfor-
mance, but high rates of wasting hindered nitrification at the interme-
diate detention times.
The relationship of ammonia removal to mixed liquor suspended solids con-
centration is presented in Figures 6-11 — 6-15.
Variations in MLSS concentration in the same unit during different phases
of operation are shown. In cases in which influent BOD was less than 40
mg/£, the amount of ammonia removed was roughly proportional to the MLSS
concentration, up to some optimal concentration for the unit. Compari-
mg NHo-N removed
sons of the different units on the basis of we consider
mg MLSS
to be invalid. Biological examination of the sludge in the five units
revealed significant differences in the flora and fauna. A six-week
study of the protozoa in the units indicated marked differences in both
numbers of protozoa and in species present (James and Little, 52). While
large numbers of protozoa, especially stalked ciliates, were present at
the shorter detention times, very few protozoa were present at the longer
detention times. In order to make a valid assessment of the relationship
of MLSS concentration to ammonia removal, it will be necessary to find
some way to measure the relative weight of nitrifying bacteria in each
sludge.
The possible enhancement of nitrification by activated sludge treatment
following high-rate trickling filtration is indicated in Tables 6-11 and
6-12. Change in concentration of various nitrogen forms during treat-
ment, from the plant influent, filter effluent, and plant effluent to
the effluents from the activated sludge pilot units, is shown in Table
6-11. Note that during cold seasons little nitrogen removal occurred in
the main plant; in warm seasons some nitrogen removal occurred, and a

*Influent to activated sludge units

-------
higher percentage of the influent nitrogen was converted to ammonia.
At no time did nitrate concentration in the filter effluent average more
than about 0.7 mg/£. Effluents from the activated sludge pilot units,
operated year-round at 25 C, always contained significant amounts of
nitrate except under conditions of high loading and short detention time.
Table 6-12 shows the changes in nitrogenous oxygen demand which can be
achieved with tertiary activated sludge treatment.
Nitrogenous oxygen demand (NOD) was calculated assuming that all the
Kjeldahl nitrogen would ultimately be converted to ammonia nitrogen. The
oxygen demand of each milligram of ammonia-nitrogen was estimated at 4.33
mg 02 (53). In addition, Table 6-12 indicates the improved NOD removals
which could be achieved with improved solids removal, based on kjeldahl
nitrogen concentration before and after centrifugation. As pointed out
previously, the pilot settling basins did not achieve effective solids
removal.
From these investigations, the following conclusions seem warranted:
1. the tertiary activated sludge process is capable of considerable
reduction of the NOD in trickling filter effluent
2. the amount of NOD reduction is largely a function of detention
time and BOD loading
3. in continuously operated units allowed to operate at pH levels
below 7 the effect of pH on extent of nitrification does not
appear to be as important as indicated by previous investiga-
tors
4. the effects of pH and alkalinity require further study so that
the relative importance of each factor can be determined
5. to formulate a valid description of the relationship of MLSS
concentration to nitrifying activity, a method of determining
the relative number of nitrifiers in a given sample of sludge
must be devised.
Further development and refinement of models such as those proposed by
Downing and Knowles (54) and by Lijklema (55) would be facilitated if
the numbers of nitrifiers in sludge could be accurately determined.
B. 3.0 GPM ACTIVATED SLUDGE PILOT PLANTS
1. Design
Because the results of the experiments with the 0.1 gpm activated sludge
pilot plants were encouraging, three activated sludge pilot plants were
constructed to permit operation on a reasonably large scale (3 gpm) to
investigate further the effects of aerator detention and other parameters
on performance. Each plant consisted of an aeration tank, final settling
tank, sludge return pump, air compressor, automatic sampling system and
all necessary control facilities.

101
-------
To prevent accumulation of solids in the totally mixed aeration tanks,
the tanks were constructed with conical bottoms, with air introduced at
the bottom tip of the cone. Because it was desired to avoid mechanical
sludge removal equipment, the final settling tanks also were constructed
with conical bottoms, having side slopes of 3:1 (vertical to horizontal)
to insure satisfactory movement of sludge to an outlet located at the
tip of the cone.
At this scale of operation, it is impossible to produce identical hydro-
dynamic effects in final settling tanks of different sizes. Because the
variables of prime interest included aerator detention times and various
loading parameters, not final settling, it was decided that the three
plants would be operated at the same hydraulic flow, using identical
final settling tanks to -avoid the hydrodynamics problem. Different de-
tention times and loadings were obtained by using three different size
aeration tanks. These did represent valid hydrodynamic equivalents be-
cause they were totally mixed, making size and shape relatively unimport-
ant. Design characteristics of all tanks in the pilot plants are sum-
marized in Table 6-13 and the plants are shown in Figure 6-16.
The total influent flow for all three plants was pumped from the effluent
of a Chapel Hill trickling filter, using a variable-speed rubber impeller
pump. This flow was divided continuously into three identical portions
by using a specially-designed rotating flow-splitter. Each plant was
equipped with a rotameter for measuring air flow. Additions of air were
regulated to maintain dissolved oxygen in the aeration tank at all times
equal to or greater than 1.0 mg/£. Return sludge was pumped continuously
from the final settling tanks to aeration tanks by means of variable-
speed rubber impeller pumps.
2. Plant Operation
The influent to these plants consisted of effluent from a trickling fil-
ter in the Chapel Hill Treatment Plant. Because the full-scale plant
was operated throughout this project on an experimental basis, with
periodic changes in recirculation ratio and rate of flow application,
influent quality to the activated sludge pilot plants varied in response
to changes in the main plant operation as well as the usual seasonal and
other variations in the process.
Unlike the smaller activated sludge studies reported earlier, there was
no effort to control temperature in the 3 gpm activated sludge plants.
Accordingly, temperature in the aerators varied with changes in tempera-
ture of the trickling filter effluent. Of course, because these units
were located in a heated building, there was little or no further change
after introduction into the aeration tanks, as might have been expected
if the plants had been operated outside in an exposed location.
Dissolved oxygen in the aeration tank was maintained in the range of
1.0-4.0 mg/& at all times. Sludge was wasted three times a day from the
system.
102
-------
Samples of influent to the units and overflow from each settling tank
were collected for one day three times per week. Each composite was
collected automatically by pumping equal volumes, at 30-minute intervals,
into refrigerated containers. The sampling system was designed to purge
the sample lines automatically before diverting a portion of flow into
the sample container.
Analyses were conducted for BOD5, total organic carbon (TOC), suspended
solids (SS), volatile suspended solids (VSS), Kjeldahl nitrogen (Kjeld-
N), ammonia nitrogen (NH3-N), oxidized nitrogen (N02 - N + NOo-N), total
phosphorus (TP), total inorganic phosphorus (TIP), turbidity (JTU),
and pH. Grab samples of mixed liquor and return sludge were analyzed for
suspended solids (MLSS and RSSS) and volatile suspended solids (MLSS and
RSVSS). Daily measurements were made of dissolved oxygen (oxygen probe
method), temperature, influent flow rate, return sludge flow rate, and
settleable mixed liquor solids.
Because results obtained from the smaller activated sludge units had
indicated the importance of solids carryover from the final tanks, com-
posite samples from the larger plants were analyzed "as is" and centri-
fuged (2200 g, International Model UV Centrifuge) for BOD, TOC and
Kjeld-N.
3. Results and Discussion
The original intent was to conduct studies at various BOD/solids load-
ings by adjusting the rate of sludge wasting. It was determined that
wasting MLSS on a predetermined pattern would not control the solids
adequately because MLSS varied markedly even during extended periods in
which daily wasting was maintained at a constant rate. Daily calcula-
tion of the proper amount of sludge to waste to maintain a specified
MLSS was impractical because a very large, but unknown, proportion of all
solids in the system at any given time was in the settling tank, which
was larger than the aerator.
Statistical analyses of preliminary data indicated no significant corre-
lation between BOD, solids loading and performance. The only clear
correlation established was between detention time in the aerator and
performance. An exception was that the degree of nitrification (ammonia
removal during treatment), increased with aeration time and concentra-
tion of MLSS, when influent BOD was less than 40 mg/£ (Figure 6-17).
This also had been observed in data from the 0.1 gpm activated sludge
units, described earlier.
Because of the difficulty in maintaining constant MLSS, variation in
solids during any given experimental period was found to be about as
great as that bejtween successive experimental periods. Examination of
data for the'different chronological periods of experimentation indica-
ted that the most reasonable approach appeared to be to combine results
for the entire period from July 1, 1971 through January 27, 1972.

-------
Mixed liquor suspended solids tended to decrease with increasing deten-
tion time in the aeration system. The sludge volume index for all units
was within a range generally considered to be acceptable (56), but as
pointed out by Dick and Vesilind (57) this really is not a very good
performance criterion. Aerator loadings (g BOD/gMLSS/day) fell within
ranges generally representative of many plants in practice (58).
Table 6-14 summarizes characteristics of untreated sewage, trickling fil-
ter effluent, and effluent from each of the three activated sludge pilot
units. Based on data for BOD and TOC in Table 6-14 and Figure 6-18,
the activated sludge units gave significant but not radical improvement
in plant performance beyond the trickling filters. BOD removal increas-
ed by 3-8% and TOC removal increased by 5-7%. Suspended solids removal
were not improved by addition of activated sludge to the main plant,
although turbidity was significantly better. Effluent suspended solids
reflect the same poor quality of settling observed earlier with the
smaller activated sludge pilot units.
Figures for soluble BOD and soluble TOC show the type of performance
which could be anticipated with removal of fine solids from the plant
effluent. Removal of suspended material, perhaps by filtration, from
the trickling filter effluent would increase overall performance from
78% to 88% BOD removal, approximately 50% removal of BOD in the current
plant effluent. Addition of activated sludge unit including removal of
solids, would give substantial further improvement to produce overall
performance of 93-94% BOD removal. Although TOC removals are somewhat
lower, as expected, they show the same types of trends observed for the
BOD data.
The most striking change in performance attending addition of the acti-
vated sludge system is reflected in large decreases in Kjeld-N. This
can be attributed to more complete nitrification in the activated sludge
units. The nitrogenous oxygen demand (NOD) of effluent from the main
plant averaged 121 mg/£, a figure which was reduced in the activated
sludge effluents to 66, 54, and 41 mg/£, with increasing detention times.
This produces a very significant improvement in removal of oxygen demand,
when considering both carbonaceous and nitrogenous materials (Figure
6-19).
Further, it may be noted that addition of the activated sludge units re-
sulted in substantial decrease in total nitrogen content of the effluents,
presumably because of denitrification in the final settling tanks. Gas
formation was observed in those tanks frequently and this could have con-
tributed to relatively poor solids removal by those units.
The data suggest that addition of this activated sludge modification,
with detention periods of 0.9-2.3 hrs, could improve BOD removal by a
trickling filter plant, but only slightly unless additional steps are
taken to remove suspended materials from the effluent. Without solids
removals it appears that addition of the activated sludge would not be

advantageous unless the Increase in nitrification would provide suffi-
cient justification, which would be unlikely in most instances.
Combination of the activated sludge modification with filtration or other
treatment appropriate for removing suspended material would produce sub-
stantially improved performance, with BOD removals exceeding 90%. One
appropriate means for suspended solids removal would be in conjunction
with chemical precipitation-flocculation for phosphorus removal. In this
instance, effluent quality should be excellent, with potential for very
low BOD, substantial nitrification and removal of most phosphorus.

Description of Data Listing Format
All of the routine data collected on the Chapel Hill Main Plant from
November 19, 1969 to January 24, 1972 are listed in this appendix. The
data list is in seven sections. Each section lists a different group of
variables for the entire period of data collection. The date, day of
week, and sample types are repeated in each section. Blanks in the
tables indicate that the particular parameter was not determined on that
date with the given sample type.
As discussed in Section V, the main plant consists of two parallel units,
Side 1 and Side 2. The numbers in the variable labels refer to the side
of the plant. Samples were routinely collected at seven points of flow.
These were influent (labelled INF), primary tank effluent (labelled P-l
or P-2), trickling filter effluent (labelled F-l or F-2), and final set-
tling tank effluent (labelled S-l or S-2).
The variable "Samp Type" refers to the type of sample (composite, grab,
etc.) on which the analyses in a given line of data were made. The
description of the code is in the next section. On many dates two dif-
ferent types of samples were collected. These dates are listed twice
with the values of each variable appearing on the line with the appro-
priate sample type. Hydraulic data is listed for each line in the file.
Thus, if the date appears twice, the hydraulic data will also appear
twice.
Variable Definitions and Units

VARIATIONS IN CHARACTERISTICS OF WASTEWATER INFLUENT AT THE MASON FARM
WASTEWATER TREATMENT PLANT, CHAPEL HILL, NORTH CAROLINA.

Wastewater Research Center Report No. 13, December, 1970. 47 pp. EPA-
WQO Contract No. 14-12-505.
Variations in characteristics of wastewater from the Town of Chapel Hill
(N. C.) were studied. Composite samples of domestic wastewater influent
were collected at 2-hr intervals over 24-hr periods on each of the seven
days of the week so that diurnal variations in flow and constituent con-
centrations and loadings could be observed. Samples were analyzed for
BOD, COD, TOC, nitrogen, phosphorus, MBAS, and specific solids and
metal constituents. Influent flow was found to vary from 30 to 144 %
of average with the maximum flow occurring between 1000-1200 hours and
the minimum flow between 0400-0600 hours. Wastewater constituents
showed a wide range of concentrations and loadings. Generally maximum
concentrations and loadings occurred between 1000-1400 hours and the
minimum values between 0600-0800 hours. The ratio of maximum to minimum
concentrations for the constituents varied from 4-12 to one; for load-
ings, from 10-20 to one.

ACTIVATED SLUDGE MODIFICATIONS FOR ENHANCEMENT OF TRICKLING FILTER
PLANT PERFORMANCE. I. Design, Operation, and BOD Removal in the Units.
II. Nitrification.
University of North Carolina, Chapel Hill, Wastewater Research Center.
Donald E. Francisco, Linda W. Little, and James C. Lamb III.
Wastewater Research Center Report No. 15, April, 1971. 43 pp. EPA-WQO
Contract No. 14-12-505.
Presented at the 20th Annual Southern Water Resources and Pollution
Control Conference, Chapel Hill, North Carolina, April 2, 1971.
Enhancement of trickling filter plant performance by subsequent activa-
ted sludge treatment was investigated. Five activated sludge pilot
plants, each consisting of aeration tank and settling tank with air lift
sludge return, were fed trickling filter effluent at a constant rate
(300 m£/min).
Hydraulic detention times in the aeration units were 0.4, 1.7, 4.0 and
9.2 hrs. Temperature was maintained at 25°C. Effects of pH control,
sludge wasting, and detention time were evaluated. Results indicated
that activated sludge treatment substantially increased overall BOD,
COD, organic carbon, and MBAS removals. At detention times of at least
1 hr significant nitrification was achieved. Control of pH with NaHCO^
improved nitrification efficiency; however, substantial nitrification
was achieved at pH levels below 7. Control of wasting and of return
sludge was necessary for optimum BOD, COD, and organic carbon removals
and for optimum nitrification.

••16.- • ; The Chapel Hill high rate trickling filter plant which consists of two paral-
lel and equal lines of treatment units was operated in parallel as two separate plants
over a period of 26 months. Each side was operated with various fractions of influent
flow and recirculation flow rates. Statistical analysis of operating results Indicated
that the common mathematical models are not reliable in predicting daily performance at
the Chapel Hill plant. They are, however, useful in predicting long term average perfor-
mance. Recirculation ratios as high as 3.0 proved beneficial at total hydraulic loadings
of less than 20 mgad. Operation above this loading is not currently feasible at Chapel
Hill.
The hydraulic surface loading of the final settling tanks was found to have a significant
effect on overall plant performance. A surface loading of 500 gpd/ft2 is recommended for
the design of final tanks in new plants.
Pilot plant studies using 4-foot diameter rock filters indicate a significant advantage
for two-stage filtration even though the hydraulic loading on each stage may be double
that for single-stage operation.
Pilot plant studies of activated sludge treatment of trickling filter effluents were con-
ducted. The process proved effective in improving removal of BOD, if effective final
solids removal facilities are provided.The process also proved effective in reducing
ij&, Jj€lic'jJ|/iOjrs
nitrogenous oxygen demand.
