FOREWORD
The Environmental Protection Agency was created because of increasing public
and government concern about the dangers of pollution to the health and welfare of the
American people. Noxious air, foul water and spoiled land are tragic testimony to the
deterioration of our natural environment. The complexity of that environment and the
interplay between its components require a concentrated and integrated attack on the
problem.
Research and development is that necessary first step in problem solution, and it
involves defining the problem, measuring its impact, and searching for solutions. The
Municipal Environmental Research Laboratory develops new and improved technology
and systems for the prevention, treatment, and management of wastewater and solid
and hazardous waste pollutant discharges from municipal and community sources, for
the preservation and treatment of public drinking water supplies, and to minimize the
adverse economic, social, health, and aesthetic effects of pollution. This publication is
one of the products of that research; a most vital communications link between the
researcher and the user community.
It provides a documentation of the operation and an evaluation of the impact of
flow equalization as applied to a medium-sized municipal wastewater treatment plant.

ABSTRACT
A plant-scale research program was carried out for more than a year to evaluate
the impact of flow equalization on the 14,000 m /day (3.7 mgd) upgraded activated
sludge plant at Ypsilanti Township, Michigan. Process streams were characterized
under both equalized and unequalized flow conditions with respect to BOD, COD, TSS
and forms of nitrogen and phosphorus.
The equalization system was effective in leveling influent diurnal flow variations
but was limited in its ability to dampen variations in wastewater concentration and
mass flux. Some biochemical action apparently occurred in the equalization basin,
although BOD removal was marginal and inconsistent. Analysis of secondary effluent
indicated that plant performance was similar with and without equalized flow,
suggesting that the theoretical advantages of flow equalization may not be achieved in
manually controlled plants. An examination of theoretical power costs for equalized
and unequalized flow conditions indicated that the use of flow equalization did not
result in power cost economies.
This report was submitted in fulfillment of Grant No. S 801985 by Ypsi-
lanti Township under the sponsorship of the U.S. Environmental Protection
Agency. Work was subcontracted to Johnson § Anderson, Inc. The report
covers the period June 1974 to August 1975, and work was completed as of
December 1976.

SECTION I
INTRODUCTION
Most municipal treatment plants experience variations in the quantity and quality of
influent wastewater. Such variations occur according to the time of day, day of the
week, and season of the year. Their magnitude is primarily a function of the size and
characteristics of the sewer system, the degree of infiltration-inflow, and the relative
impact of industrial contributors.
Recently, there has been a considerable amount of interest in the use of flow equaliza-
tion basins to smooth out the diurnal fluctuations of concentration and flow rate at
municipal treatment plants. For example, at least three feature articles have appeared
in technical magazines since 1974 highlighting the presumed benefits and applications of
1 3
flow equalization. Among the reported advantages are the following:
1. Equalization improves performance of sedimentation basins by leveling
hydraulic variations and reducing peak flow rates; in so doing, it permits
smaller requisite clarifier sizes in new plant design or increases capacity of
existing units.
2. It benefits biological treatment by producing increased uniformity in the
concentration and flux of organics and nutrients in the wastewater, as well
as more stable retention periods and biomass concentrations in the aeration
basin.
3. It simplifies manual and automated control of flow-rate dependent opera-
tions, such as chemical feeding, disinfection, sludge pumping, etc.
-------
4. It improves the settleability of wastewater and provides some BOD
reduction and odor removal (if aeration is used for mixing in the equalization
basin).
5. It provides a point of return for recycling concentrated waste streams,
thereby mitigating shock loads to primary settlers or aeration basins.
6. It provides the potential for lowering energy costs by dampening peak power
demands for pumping and aeration.
Actual operating experience with flow equalization systems is quite limited and has
produced some mixed results. LaGrega and Keenan found that suspended solids
removal in a primary settler improved with flow equalization and that the standard
deviation of primary effluent data was substantially lower under equalized conditions
for the variables tested (BOD, COD, TOC, TSS and VSS). The diurnal variations in these
experiments produced a peak-to-average flow rate ratio of less than 1.5. The results of
Boon and Burgess were less promising. These authors performed pilot plant studies
with parallel activated sludge systems in which one system operated with constant flow
and the other with diurnally varying flow at a peaking factor of 2.1. Data obtained
failed to show that flow equalization had any significant effect on 2^-hour composite
BOD removal; however, effluent BOD was found to be more consistent under constant
flow conditions. In a plant-scale study, Foess, et al compared the performance of an
underloaded plant under sequential periods of equalized and normal flow. They found
that the performance of tertiary filters was better when the flow was equalized but
that equalization had no discernible effects on the activated sludge system perform-
ance.
In activated sludge systems, fluctuating flows have the potential to generate (a) a
biological response, wherein the biochemical efficiency of substrate removal might be
affected; (b) a biophysical response, in which changes in sludge settleability might
occur; and (c) a purely physical response in which the liquid-solids separator might
become overloaded at the peak diurnal flow. According to George and Gaudy, the
biological response in completely mixed systems becomes significant only after there is
9
a flow rate increase of more than 100 percent. Busby and Andrews showed that both
the biological and biophysical effects of diurnal variations can be mitigated by
application of one or more available control strategies designed to regulate MLSS
-------
without the need for flow equalization.* Thus, the liquid-solids separation step is the
one that appears to be the most sensitive to flow rate variations and is the one that was
focused on in this study.
g
The cost-effectiveness of flow equalization is another area of uncertainty. Smith et_al
and the Ontario Ministry of the Environment have performed work in this area but the
reported results were considered by each author to be preliminary in nature. Plant
operating data with and without equalization are needed before a final determination
of the cost-effectiveness of equalization can be made.
Techniques for designing the equalization basins themselves are fairly well established.
In municipal wastewater treatment, the objective is usually to equalize flows rather
than concentrations and the conventional mass diagram approach can be used. If con-
centration dampening is the objective, several analytical methods are available,
but their focus is on industrial rather than municipal wastes. Modeling of equalization
basin performance is generally based on assumptions of complete mixing and
conservative (nondegradable) substances. There is a virtual lack of published
performance data on equalization basins receiving municipal sewage. The work
reported herein will provide information on the magnitude of BOD reductions and other
biochemical transformations that may occur across an equalization basin.
*Such control strategies include, for example, 1) varying sludge return rate in
proportion to influent wastewater rate, 2) varying the recycle flow rate in accordance
with the height of the sludge blanket in the darifier, 3) regulating waste sludge flow
rate as a function of sludge blanket height, and 4) using continuously adjusted step-feed
contacting patterns.
-------
SECTION II
SUMMARY
A plant-scale research program was carried out for more than a year to evaluate the
impact of flow equalization on the operation and performance of a conventional
activated sludge plant. The studies were conducted at the Ypsilanti Township, Michigan
treatment plant, an upgraded 14,000 m3/day (3.7 mgd) facility containing an "in-line"
j
equalization basin with a capacity of 2377 mj (628,000 gal). The average daily plant
flow was about 15,140 m /day (4 mgd) while peak hourly flows were around 22,700
m /day (6 mgd).
Daily 24-hr composite samples were collected from process streams before and after
equalization and after final clarification; in addition, a more rigorous sampling and
analysis program was conducted during a few days each month in which bi-hourly
composite samples were collected and analyzedi For comparative purposes, short-term
data were obtained on plant performance after taking the equalization basin out of
service. Special studies were also conducted in which the plant was stressed in both the
equalized and unequalized modes by selectively removing final clarifiers from service,
thereby increasing the overflow rate in the remaining clarifiers.
The equalization system functioned in a reliable manner throughout the study and was
highly effective in leveling influent diurnal flow variations and providing a uniform daily
flow rate to the activated sludge process. The degree of concentration and mass
dampening achieved was much more limited and appreciable variability of strength
remained in the equalized stream. Statistical analysis of the data revealed that reduc-
tions in the variances of BOD- TSS and other constituents such as COD, SOP, TP, and
NH--N across the equalization basin were in the range of about 20 to 80 percent based
on concentration and 45 to 95 percent based on mass.
-------
Comparison of mass flux data into and out of the equalization basin for TSS, BOD, COD,
SOP, TP, NH,-N and TON indicated that some biochemical action occurred in the basin.
There was a definite increase in suspended solids across the basin but BOD- removal
was marginal and inconsistent.
Analysis of secondary effluent indicated that the effects of flow equalization were
apparently less important in determining effluent quality than the effects of other
operational variables such as organic loading intensity, sludge settleability, wind and
density currents, recycle rate, sludge blanket height, chemical dose (for P precipita-
tion), etc. This was evidenced by a) the similar removals of TSS and BOD 5 that were
obtained with and without equalized flow, and b) the lack of sensitivity of final clarifier
performance to diurnal variations in overflow rate for overflow rates up to
57 m3/day/m2 (1400 gpd/sq ft).
An analysis of costs showed that the capital costs associated with conversion of existing
digesters to equalization basins were only about 25% of those that would have been
experienced with construction of new equalization facilities. An analysis of theoretical
power costs for equalized and unequalized flow conditions indicated no power cost
economies occurred with flow equalization. Reductions in demand charges were slightly
less than increased energy charges during equalized flow periods.
-------
SECTION III
CONCLUSIONS
1. Existing digesters, which might otherwise be abandoned in a plant expansion, can
be converted to workable equalization basins (Section VIII, p. 22).
2. At the Ypsilanti Township treatment plant, the use of flow equalization does not
add measurably to overall labor requirements for the plant (Section VIII, p.
3. The degree of concentration and mass dampening will be limited in in-line equal-
ization basins which are sized to level only diurnal flow variations, as evidenced
by the reductions in variance of waste parameters across the equalization basin
in these studies. Variance reductions for TSS, BOD^, COD, SOP, TP, NFiL and
TON ranged generally from 20 to 80 percent for concentration and 45 to 95
percent for mass (Section VIII, p. 30).
4. Equalization produces changes in the waste as a result of biochemical action
within the basin but such changes are small. For example, BOD^ reduction
across the equalization basin averaged only about 7 percent, while some growth
of biomass occured, causing an increase in TSS of about 9 percent (Section VIII,
p. 30).
5. Performance of the Ypsilanti Township plant was very similar under both
equalized and normal flow conditions, even when the final clarifiers were
7 j
hydraulically stressed to overflow rates as high as 57 m /day/m (1400 gpd/sq ft)
(Section VIII, pp. 4 1-48).
-------
6. The theoretical advantages of flow equalization were not achieved in this
manually controlled activated sludge treatment plant operated at and above
conventional design loading ranges. It is concluded that any beneficial effects of
flow equalization were overshadowed or neutralized by a) suboptimal application
of control schemes for the biological process, and b) a lack of sensitivity of final
clarifier performance to normal variations in flow rate (Section VIII, pp. 44-48).
7. The covered equalization basin at Ypsilanti Township had no significant effect on
wastewater temperature; basin influent and effluent readings were generally
within 1°C (Section VIII, p. 48).
8. In the Ypsilanti Township equalization basin, the aeration requirements for
providing complete mixing are greater than for maintaining aerobic conditions.
The minimum level of aeration for preventing solids deposition was about 7.5x10
m3/min/1 (1.0 cfm/1000 gal) of storage (Section VIII, p. 49).
-------
SECTION IV
RECOMMENDATIONS
The results of the work reported herein indicate that while flow equalization does
provide certain benefits, it is by no means a panacea for improving the performance of
activated sludge plants. Thus, engineers should not specify the use of flow equalization
indiscriminantly but rather should critically evaluate its merits on a case-by-case basis.
If additional research related to flow equalization is undertaken, the following deserve
further consideration:
1. The variation in percentage removals obtained by primary clarifiers and
effluent suspended solids carryover by secondary clarifiers should be
evaluated for different intensities of flow and strength variations.
2. The effects of flow equalization on the requisite sizes of downstream treat-
ment units should be determined.
3. The relative importance of flow equalization versus concentration and mass
equalization should be evaluated.
4. The limitations of equalizing diurnal flow variations while permitting day-
to-day, weekly, and seasonal variations to continue should be studied.
5. The effects of flow equalization on chemical treatment processes, such as
phosphorus removal, need further clarification.
-------
SECTION V
EXPERIMENTAL PLAN
The experimental program was undertaken to demonstrate the impact of flow
equalization on the operation and performance of a conventional activated sludge plant
treating municipal sewage under practical operating conditions. In general, the
approach was to compare the relative process performance of the plant under
consecutive periods of equalized and unequalized operation. A side by side comparison
of equalized and unequalized activated sludge systems was also possible in that there
were two independent parallel plants on the site; however, this comparison was of
limited value because the plants did not receive the same feed wastewater. The
specific program objectives were the following:
1. Demonstration of the applicability of employing flow equalization in
upgrading an existing activated sludge treatment plant.
2. Characterization of the effects of flow equalization on the concentration
and mass of organics and nutrients in the wastewater.
3. Comparison of process treatment effectiveness and economics of equalized
and unequalized-flow activated sludge systems operating under conventional
organic loadings (0.2-0.5 g/g-day) and aeration detention times (5-6 hours
based on raw flow), and moderate to high final clarifier overflow rates of
29-57 m3/day/m2(700-1400 gpd/sq ft).
4. Evaluation of overall plant operation with respect to the relative ease or
difficulty of operating in the equalized versus the unequalized mode.
-------
These studies were conducted using the Ypsilanti Township, Michigan, Municipal
Treatment Plant with the cooperation of Township officials and the treatment plant
staff. The existing Ypsilanti Township treatment facility comprises two parallel
activated sludge plants. Plant No. 1 was completed in 1942 with a design flow of 9,460
m /day (2.5 mgd), but was upgraded to treat 14,000 m3/day (3.7 mgd) and equipped with
flow equalization in 1973. Plant No. 2 was completed in 1965 and designed for an
average daily flow of 14,380 m /day (3.8 mgd). As data presented here will illustrate,
the average daily flow of each plant is about 14,000 m3/day (3.7 mgd) with hourly flow
variations from 5,680 to 22,700 m3/day (1.5 to 6.0 mgd). The BOD strength of the
incoming wastewater to each plant averages about 200 mg/1 with hourly variations from
50 to 400 mg/1. Feed wastewater to each plant is predominately of domestic origin but
contains a representative portion (about 25 percent) of industrial waste.
The experimental plan was carried out over approximately a 14-month period.
Essentially three modes of operation of Plant No. 1 were studied: i) equalized flow at
approximately the design capacity of the plant; ii) equalized flow under hydraulically
stressed conditions in the final clarification step; and iii) unequalized (normal diurnal)
flow conditions. No changes were made in the operation of Plant No. 2 throughout the
study; this plant had no direct role in the research other than serving as a general
control.
The program objectives and plan described in the preceding reflect some changes which
were made during the course of the project. Originally, it was hoped to modify the
influent works so that both plants received the same wastewater; however, budgetary
limitations did not permit these modifications to be made. It was also hoped to modify
the influent works so that the diurnal flow variations to Plant No. 1 could be magnified;
these modifications were also not implemented because of lengthy delays in equipment
delivery.

PLANT AND EQUIPMENT DESCRIPTION
Plant No. 1
General Description
The waste water treatment complex in Ypsilanti Township, Michigan contains two inde-
pendent treatment plants (See Figure 1). Most of the experimental work was performed
on Plant No. 1, a plug-flow activated sludge facility equipped for flow equalization and
ferric chloride and polymer addition to the aeration basin effluent. The plant has a
design treatment capacity of 14,000 m /day (3.7 mgd) based on a final clarifier
^» *\
overflow rate of 32.6 m /day/m (800 gpd/sq ft). There are no primary clarifiers at
Plant No. 1.
Raw sewage from a portion of the Ypsilanti Township collection system enters a
pumping station (Snow Road Lift Station) located remotely from Plant No. 1. The
sewage is pumped directly to the equalization tanks and then is re-pumped to a bar rack
channel. Gravity flow occurs through the remaining plant processes which consist
respectively, of aeration, final settling, and disinfection. The equalization tanks can be
by-passed by pumping raw sewage from the pumping station directly to the bar rack
channel.
Equalization System
The equalization system at this plant is the in-line type. Two existing digesters were
converted to equalization tanks, providing an effective retention capacity of 2,362
m3 (624,000 gal) which is about 17 percent of the average daily design flow. Figure 2
depicts pertinent features of the tanks.

-------
The process flow rate out of the equalization tanks is regulated by precisely maintaining
the desired liquid level in the plant bar rack channel. This is achieved by a liquid level
controller in the channel tied to a throttling valve located directly after the equaliza-
tion pump. Thus, if the liquid elevation in the channel begins to vary from the preset
level, the throttle valve is automatically opened or closed to maintain the desired level.
There is only one equalization pump; it has a capacity of 126 1/s (2000 gpm) at a TDH of
9.1 m (30 ft).
Air is supplied to the equalization tanks by a single positive displacement compressor
with a rated capacity of 25.5 m /min (900 scfm) at 0.84 kg/sq cm (12 psig) of head. A
second compressor of the same size is available as a stand-by unit. Valves and meters
were installed so that the air flow to each equalization tank can be regulated and
measured independently. Air injection is accomplished through Walker Process "Mono-
Sparg 5/32" nozzles located 0.6 m (2 ft) from the bottom of the tanks.
Aeration Basins
There are four rectangular aeration tanks which operate in parallel. Each tank is
baffled into four compartments for better plug flow characteristics. The total volume
of the tanks is 3,510 m (927,500 gal) which results in 6.0 hrs of mixed-liquor detention
time based on 14,000 m3/day (3.7 mgd) feed flow. Each tank is 7.6 m (25 ft) wide,
30.5 m (100 ft) in length, and 4.6 m (15 ft) deep.
Air is normally supplied from one 84.0 m /min (3000 scfm) positive displacement
blower. A second blower of the same size is also available when needed. The
compressed air is diffused into the mixed-liquor through Walker Process "Duo Spray
5/32" nozzles. The air pipes to each nozzle header contain valves for balancing the air
flow. Ferric chloride and polymer solutions are added to the outlet trough of the
aeration basins for precipitation of phosphorus, with the feed rate being automatically
paced to flow rate.
Final Settling Tanks
Eight final clarifiers receive the aeration tank effluent. Four of the tanks are 4.3 m
(14 ft) wide and 18.3 m (60 ft) long with a 3.7 m (12 ft) water depth. The remaining four
14
-------
are 2.6 m (8.5 ft) wide and 18.3 m (60 ft) long with a 3.7 m (12 ft) water depth. The
final 5.5 m (18 ft) of each tank contains a bank of effluent weirs. Assuming that half of
the weir bank area is ineffective for settling, the total settling area of the tanks is
426.6 m2 (4,590 sq ft). Based on an overflow rate of 32.6 m3/day/m2 (800 gpd/sq ft) the
design flow rate is 14,000 m /day (3.7 mgd).
Settled activated sludge is moved to collection hoppers in each tank by mechanical
scrapers. It then flows by hydrostatic pressure to sludge draw-off wells. From the
draw-off wells the sludge is pumped to the aeration basin influent. Excess sludge is
wasted as required to maintain a constant concentration of activated sludge in the
aeration basin. Waste sludge is pumped to the plant digester or directly to the Wayne
County trunk sewer (the digester has sufficient capacity to treat only about 20 percent
of the sludge generated). There are two return sludge pumps, each with a capacity of
63.11/s (1000 gpm) at 9.1 m (30 ft) TDH, and two waste sludge pumps, each with a
capacity of 6.3 1/s (100 gpm). The system is designed so that return sludge pumping
rates are approximately proportional to the plant flow rate. Return sludge rates for
each settler can also be independently controlled to meet process conditions at any
given time. Piping of the final settlers permits any one or more of the eight units to be
individually taken out of service.
The reason for the two different sizes of final settling tanks is that half of the settlers
were originally used as primaries. They were converted to final settlers in the
upgrading program just prior to this study. By converting primary settlers to secondary
settlers and by converting existing digesters to equalization tanks, the plant capacity
was increased from 9,460 m /day (2.5 mgd) to 14,000 m3/day (3.7 mgd) without the
addition of any new structures.
Flow Metering
Plant influent flow is measured by a magnetic flow meter at the influent pumping
station. There is digital output of the totalized flow at the treatment plant but no
continuous recording of flow rate. Plant effluent flow is measured by a rectangular
weir and is recorded on circular charts. Agreement between the influent and effluent
meters is usually within 10 to 20 percent. Some or all of the differences in
corresponding daily readings between the influent and effluent meters can be attributed
15
-------
to net accumulation or release of stored wastewater in the equalization basins.
Instances were also observed when the equalization tanks overflowed; since the
overflow goes to Plant No. 2, it would not be recorded by the Plant No. 1 effluent
meter.
Return sludge flow rate is measured with a magnetic flow meter and continuously
recorded. Waste sludge flow rate is not independently measured due to interconnection
of the waste sludge piping systems of Plants No. 1 and No. 2.
Plant No. 2
Plant No. 2 treats wastewater from three gravity lines which serve those portions of the
Ypsilanti Township system not served by Plant No. 1. The treatment system comprises
comminution, grit removal, primary sedimentation, aeration, final sedimentation, and
disinfection. Ferric chloride is added continuously to the aeration basin effluent for
3
phosphorus removal. The design treatment capacity is 14,380 m /day (3.8 mgd) based
3 2
on an overflow rate of 32.6 m /day m (800 gpd/sq ft).
Plant No. 2 contains two rectangular primary sedimentation tanks with a total effective
2
surface settling area of 452 m (4,860 sq. ft). Waste activated sludge is added to the
primary tank influent and combined primary-and-secondary sludge is therefore with-
drawn from the tanks and disposed with the sludge from Plant No. 1 (See Figure 1).
The effluent from the primary tanks flows to two rectangular aeration tanks. The total
volume of the tanks is 4,405 m (1,163,900 gal) resulting in 7.4 hrs of mixed-liquor
detention time based on 14,380 m /day (3.8 mgd) feed flow.
Two rectangular final settlers receive the effluent from the aeration basins. The
settlers have a total effective surface settling area of 440 m (4,740 sq ft).

SECTION VII
METHODS AND PROCEDURES
Concurrent with the final stages of the upgrading program at Ypsilanti Township Plant
No. 1, an analytical laboratory was established about 4 miles from the plant. This
laboratory was equipped with automated equipment and instrumentation for simultan-
eously performing routine analyses on a high volume of samples. It was intended that
this laboratory supplement the treatment plant laboratory capability by providing
analyses on samples collected on week-ends and holidays and during periods of intensive
monitoring of plant operation and performance.
Sampling and Analysis
Daily Samples
The normal daily sampling and anal ysis^ were performed by the treatment plant staff
except on week-ends and holidays when they were performed by project personnel.
Daily sampling was carried out throughout the course of the work. Table 1 shows the
various analytical measurements made on samples collected from the different plant
locations.
Daily composite samples were collected for a 24-hour period beginning at 7:00 a.m.
each day to conform with previous plant practice. The samples were composited by
mixing equal 100 ml volumes of 12 grab samples collected every 2 hours during the 24-
hour period; it was not possible with constraints on manpower and budget to flow
proportion these samples. Grab samples of mixed-liquor were taken once per day at
9:00 a.m. from the aeration basin effluent troughs of each plant.

Bi-hourly Samples
On several days each month, bihourly samples were collected by project personnel and
analyzed individually rather than composited into one daily sample. The bihourly
samples were usually analyzed for BOD5, TSS, COD, SOP, TP, NH3-N, TON, and some-
times NO.J-N. Table 2 gives the dates and plant locations that bihourly samples were
collected and analyzed.
Analytical Methods
Analytical methods used in the work are described individually below. All methods were
verified by running EPA standard samples.
Dissolved Oxygen
Dissolved oxygen measurements were performed with a membrane electrode. Compar-
ison tests using the azide modification of the Winkler titration method described in
Standard Methods were run during the course of the work to assure consistent results.
Determinations for BOD- were performed by the standard dilution method, using the
previously mentioned D.O. membrane electrode. Glucose - glutamic acid solution with
known BOD~ was analyzed with the samples to insure quality control.
Total Suspended Solids
Total suspended solids measurements were made using the standard gravimetric
technique. Gooch crucibles were used to collect the residue.
COD
Analyses of COD were performed according to Standard Methods using the
dichromate reflux method.

-------
Total Kjeldahl Nitrogen and Total Organic Nitrogen
Analysis of wastewater samples for total kjeldahl nitrogen was done according to the
kjeldahl procedure in Standard Methods. Total organic nitrogen was obtained by
subtraction of NH,-N from total kjeldahl nitrogen.
Ammonia --
Ammonia analyses were performed with the Technicon Auto Analyzer II using the
phenol-hypochlorite procedure described by Technicon. All samples were filtered
through 0.45 micron membrane filters prior to analysis to remove participate matter.
Total Phosphorus and Soluble Orthophosphate
Phosphorus analyses were performed with the Technicon Auto Analyzer II using the
18
colorimetric ascorbic acid reduction method. Some analyses were also performed
manually using the vanadate colorimetric determination of orthophosphate as described
in Standard Methods. To obtain total phosphorus, the persulfate digestion method was
employed on an aliquot of the sample to convert all phosphorus to the ortho form.
Soluble orthophosphate was determined by performing the colorimetric procedure
directly after filtration of an aliquot of the sample through a 0.45 micron filter.
Nitrite and Nitrate Nitrogen
These analyses were run by an automated procedure using the Technicon Auto
i x
Analyzer II. All samples were initially filtered through a 0.45 micron membrane filter
for removal of suspended solids. The automated procedure utilized cadmium reduction
of the nitrate and subsequent diazotization of the nitrite for color development.
Data Reduction
Raw data were tabulated and preliminarily analyzed on a monthly basis throughout the
project. At the end of the experimental work, all data were computationally reduced
using a CDC Cyber 74 computer. Special programs were written to analyze and reduce
the data to meaningful form. A listing of the data may be found in the Appendix.

SECTION VIII
RESULTS AND DISCUSSION
Equalization System Equipment Performance and Reliability
The equalization system installed at the Ypsilanti Township Treatment Plant has been
described earlier in this report. Although this system was designed utilizing two
existing sludge digestion tanks as equalization basins, with a strong emphasis on
minimizing cost, the system functioned in a highly reliable manner during and
subsequent to the periods of operation described herein. Maintenance and service for
the system were minimal and no major modifications were required after the initial
installation.
Operation and control of the equalization system was performed entirely by regular
treatment plant personnel with no unusual attention required for reliable operation. In
fact, the system typically operated fully automatically with no need for manual
attention other than routine surveillance. Throughout the study, there was no need to
by-pass the equalization basins due to failure of any of the system components,
including the equalization pump, air compressors, and controls.
The only problem experienced with the system was occasional overflowing of the equali-
zation basin. This occurred when the plant flow rate was exceptionally high over a 24-
hour period, preventing normal emptying of the tank at night. The overflows were
directed to Plant No. 2 so that the equalized flow pattern in Plant No. 1 would not be
affected. In a typical situation the overflows would have to be added back to the plant
flow, thereby rendering the equalization system ineffective for the duration of the
overflows.
22
-------
Flow, Concentration and Mass Equalization
The Ypsilanti Township equalization system is highly effective in leveling influent
diurnal flow variations and providing a uniform daily flow rate to the activated sludge
process. Plant flow charts typically show a constant flow rate throughout each day.
Because the equalization system was designed to level flow variations only within a
given day, the day-to-day, weekly, and seasonal flow variations through the plant were
not affected.
Although hourly flow equalization was reliably achieved, the degree of concentration
and mass dampening was limited. Tables 3-6 show concentrations of TSS, BOD5, COD,
SOP, TP, NH^, and TON in both the raw and equalized wastewater streams during ten
periods of bihourly testing.* Also shown in each instance are the variance, standard
deviation and coefficient of variation (standard deviation divided by the mean) of the
concentration values (See Appendix). The data show that the equalization basin reduced
the diurnal variability of waste strength by 20 to 80 percent for most of the parameters,
as measured by the variance.
Typical data illustrating concentration leveling effected by the equalization basin for a
72-hour period are presented in Figure 3. Concentrations of various constituents are
plotted as a function of time for both the raw wastewater and the equalized flow. As
shown, the equalization system somewhat reduced the diurnal variability of waste
strength and lowered the maximum concentrations of waste parameters. However, it is
also clear that appreciable variability of strength remained in the equalized stream.
The degree of mass dampening that occurred in the Ypsilanti Township equalization
basin was much greater than the concentration dampening. Mass flow values of the
various parameters for both the raw wastewater and the equalization basin during the
bihourly testing periods are listed in Table 7. Also shown for each parameter are the
variance, standard deviation, and coefficient of variation of the mass flow values.
Computations show that the reductions in the variance of the mean mass flow of each
*Only periods in which 3 or more consecutive days of data were collected are presented

parameter across the equalization basin were generally in the range of 45 to 95 percent
as compared to the 20 to 80 percent variance reduction in constituent concentrations
across the equalization basin. Mass dampening is expected to be greater than
concentration dampening because the former is a function of both flow and
concentration equalization. Figure 4 illustrates mass leveling for a representative 72-
hour period.
Mass Transformations Within the Equalization Basin
The mass flow data summarized from the bihourly testing periods shown in Table 7 give
insight into the changes that equalization produced in the waste as a result of
biochemical reactions within the basin. Comparison of the mass flow into and out of
the equalization basin, using the combined mean values in Table 7, shows that there
were reductions in BOD-, COD, SOP, and NH,-N and increases in TSS and TON. Total
phosphorus remained virtually constant across the basin, which is the expected result
based on conservation of mass. These changes are consistant with those expected to
occur as a result of biochemical action and associated growth of biomass in the
equalization basin. However, it can be observed that overall BOD5 removal for the
combined periods was only 7 percent and was inconsistent from one study period to the
next.
Additional mass flow data compiled and summarized from the daily plant records which
extend from June, 1974 to July, 1975 are given in Table 8. These data are comparable
to the bihourly data in that they show a definite increase in suspended solids across the
equalization basin but marginal and inconsistent BOD5 removal. These results tend to
confirm that growth of biomass occurred in the equalization basin but that there was
little net removal of BOD -. It should be mentioned, however, that these data have the
limitation that composite samples were not proportioned according to flow (See
Section VII).
To determine if the differences in monthly mean values of BOD^ and TSS in the
influent and effluent of the equalization basin are significant, the test statistic ZG was
computed (See Table 8). Since it was hypothesized that there would be a BOD^
reduction and a TSS increase across the basin, the one-sided test was used and the
difference in means was considered significant at the 5% level of significance (a = 0.05)

if Z_ > 1.645* for BOD. and Z < -1.645 for TSS. From Table 8 it is seen from the Z^
V* J V*1 \^
values that the mean values of BOD^ across the equalization basin were significantly
different in only one of the 14 months though 3 additional months were marginal. For
TSS, there are several Z values close to the critical value which makes it difficult to
reach a definite conclusion. Further statistical tests were run combining the data into
3-month groups to obtain the benefit of more observations per test. The results,
presented in Table 9, show that the mean TSS value in the equalization basin effluent
was significantly greater than the TSS value in the basin influent (at the 5% level of
significance) for each of the periods tested. For BOD* there was only one period in
which the difference across the basin was significant. These results further confirm
that little or no BOD5 reduction can be expected across an equalization basin but that
some growth of biomass occurs, causing an increase in TSS.
Previously reported experience with preaeration of raw sewage has similarly shown that
aeration (without sludge recycle) is relatively ineffective for BODS removal. For
19
example, Seidel and Baumann found in full-scale studies that 48 minutes of
preaeration had no measurable effect on the wastewater BOD-. In-line equalization
might be expected to provide somewhat higher levels of biological activity than a
preaeration tank because of the longer mean liquid retention period.
Activated Sludge System
Operation and Performance
Daily records of plant operation and performance were maintained by the treatment
plant staff. A tabular summary of the conditions of operation for Plant No. 1 (the
equalized plant) over a 14-rnonth period is given in Table 10. Monthly average
performance data for the plant during this same period are given in Tables 11 and 12.
The equalization basin was in service throughout this period except for the 31 days from
May 14, 1975 to June 14, 1975 when tests were performed under the unequalized mode.
* 1.645 is the tabulated value of the test statistic Zfor large n and a = 0.05; see e.g. W.

As shown in Table 10, raw wastewater flow rates were similar throughout the 14-month
period, averaging 13,970 m /day (3.69 mgd). The final clarifiers operated with an
average overflow rate of 32.8 m3/day/m2 (805 gpd/sq ft) which slightly exceeds the
a j
design value of 32.6 m /day/m* (800 gpd/sq ft). Recycle sludge flow rates averaged 69
percent of the influent flow rate during this period. Mixed-liquor D.O. concentrations
were maintained at an average of 2.1 mg/1 (for measurements taken at the head of the
aeration basin). The mean aeration period was 6.1 hr and the mean aeration rate was
119,980 m3/day (4,236,500 cu ft/day) which is equivalent to approximately 0.0086
m /I (1.15 cu ft/gal) of sewage treated.
Table 10 also shows that there was some difficulty in maintaining a constant MLSS
concentration throughout the study period. The mean MLSS concentration during the
14-month period was 1977 mg/1, with monthly mean values ranging from 1461 mg/1 to
2735 mg/1. The organic loading intensity, F/M, also varied considerably, exhibiting a
range of 0.39 to 0.80 g/g day (Ib/lb day) and a mean of 0.55 g/g day (Ib/lb day).
To illustrate the treatment effectiveness of Plant No. 1, values of some wastewater
quality parameters for the plant influent, equalization basin effluent, and final effluent
are given in Tables 11 and 12. Also shown are the percentage of BOD-, TSS, VSS and TP
removed by secondary treatment. As in most of the data presented here, values for the
mean, standard deviation, variance, and coefficient of variation are listed in each
instance.
As illustrated by examination of the data in Tables 11 and 12, the percentage removals
of BOD 5, TSS and VSS were relatively consistent throughout the study period and were
typical of those expected from a conventional activated sludge plant (averaging about
91 percent for all three parameters). Percentage removals of TP across the plant were
not consistent, ranging from 59 to 87 percent, and reflect some of the difficulties with
the ferric chloride feed system (pump malfunctions and line plugging). These
difficulties did not appear to have much effect on TSS removal in the plant.
Figure 5 illustrates TSS and BOD plant effluent data collected under unequalized and
equalized flow during March-July 1975. There is little apparent difference evident in
the level or consistency of effluent TSS and BOD concentrations obtained under each
condition. Effluent TSS concentrations averaged 9 mg/1 during the unequalized flow

period versus 14 mg/1 and 11 mg/1 during the two equalized flow periods, while effluent
BOD- concentrations averaged 11 mg/1 during the unequalized flow period versus
12 mg/1 and 13 mg/1 during the two equalized flow periods. Table 13 presents a
summary of the average conditions of operation and mean performance values for the
31-day period of unequalized operation and for the two 31-day periods of equalized
flow which preceded and followed unequalized operation. Like Figure 5, Table 13
shows that final effluent quality (in terms of BOD, TSS and VSS) and percentage
removals were very similar during the respective 31-day periods of comparison.
Throughout the periods of testing, the plant operated without upset and, as shown in
Table 13, exhibited good sludge settleability. While unavoidable changes occurred in
some of the operating parameters, such as F/M, the principal experimental variable was
the presence or absence of diurnal flow variations; thus, in this practical situation, flow
equalization had little or no beneficial effect on plant effluent quality.
Intensive Studies
The limited amount of bihourly data which was collected on the final effluent stream of
the equalized plant is included in Tables 3-6. The conditions of operation during the
periods for which bihourly effluent data were collected are summarized in Table 14.
Some helpful insight into the effects of equalization can be gained by examining these
study periods individually.
During the intensive study periods in March through June, 1975, the emphasis in the
experimental program was on (i) stressing Plant No. 1 in the equalized mode by
selectively removing final clarifiers from service, thereby increasing the overflow rate
in the final clarifiers, and (ii) taking the equalization basin out of service and running
Plant No. 1 under stressed and unstressed conditions with normal diurnal flow
variations. These experiments were undertaken to permit comparison of plant
performance under both equalized and unequalized flow conditions and at both normal
and elevated final clarifier overflow rates.
(1) On March 10, four clarifiers were removed from service at 8:30 a.m. The effluent
deteriorated with high suspended solids carryover; measurements taken every
half-hour showed that TSS reached 300 mg/1 and BOD,- was as high as 378 mg/1.

During this period, the plant flow was equalized at 15,900 m /day (4.2 mgd), which

gave a final clarifier overflow rate of 74.7 m /day/m (1830 gpd/sq ft) based on a
surface settling area of 213 m (2,296 sq ft). The solids loading was about
129 kg/day/m (26.5 Ibs/day/sq ft). All clarifiers were put back on line at 10 a.m.
after 1-1/2 hours because of continued poor effluent quality.
(2) On March 17, three large clarifiers were removed from service at 9:00 a.m.
2
yielding an available surface settling area of 228 m (2450 sq ft). Plant flow rate
at the time was equalized at about 16,275 m /day (4.3 mgd) which gave an
i "j
overflow rate of 71.6 m /day/m (1755 gpd/sq ft) and a solids loading of about
2
132 kg/day/m (27 Ibs/day/sq ft). Results were poor, necessitating that the
experiment be suspended. Beginning at 11:00 on the same day, the plant was
operated after taking two small clarifiers and one large clarifier off-line. The
resulting arrangement produced a surface settling area of 280 m (3,010 sq ft) and
an overflow rate of about 58.3 m /day/m2 (1430 gpd/sq ft). Based on MLSS of
2
1266 mg/1 and a recycle rate of 60%, the solids loading was 118 kg/day/m
(24.1 Ibs/day/sq ft). A good effluent was produced with BOD- and TSS values
averaging less than 10 mg/1; however, the experiment was terminated at 3:00 p.m.
after 4 hours of operation by instructions from the plant operator.
(3) On April 14, four small clarifiers were taken out of service at 9:00 a.m. leaving
264 m (2842 sq ft) of surface settling area remaining (with equalized flow). The
effluent deteriorated rapidly, necessitating that the clarifiers be put back on line
within one hour. Part of the problem with this particular mode of operation
seemed to be an uneven flow distribution among the clarifiers.
(4) On April 16, three small clarifiers were removed from service at 9:00 a.m. under
2
equalized flow conditions. The resulting surface settling area of 306 m
(3290 sq ft) and plant flow rate of 16,650 m /day (4.4 mgd) produced an average
overflow rate of 55 m /day/m (1340 gpd/sq ft). The solids loading was
approximately 17 kg/day/m (35.1 Ibs/day/sq ft), based on MLSS of 2268 mg/1 and
a recirculation ratio of 38%. Effluent quality was generally poor with progressive
deterioration through the day; BOD- results were better than those for TSS but
hexavalent chromium and phenols were detected in the wastewater and it is
possible that the BOD,. results were low due to toxic effects.
43
-------
(5) During the May 18-22, June 3-5, and June 10-12 study periods, the equalization
basin was removed from service. The performance and operation data (Tables 3-6
and Table 1*0 show that final effluent quality was good during each period, despite
the fact that the plant was stressed during the latter two periods by removing
final clarifiers from service. These results indicate that the plant is capable of
producing a good effluent with or without flow equalization.
(6) From June 30 to July 2, 1975, the plant was operated in the equalized mode but
two clarifiers were taken off-line to obtain performance data under stressed
conditions. The average plant flow for the three days of testing was
13,130 m /day (3.47 mgd), yielding an average final clarifier -overflow rate of
32 ")
41 m /day/m (1002 gpd/sq ft) based on a surface settling area of 322 m
(3,462 sq ft). The MLSS concentration was 2,178 mg/1 and the sludge recycle rate
64%, resulting in a clarifier solids loading of 145 kg/day/m2 (29.7 Ibs/day/sq ft).
The performance data indicate that there was no apparent effluent quality
deterioration during the testing period.
(7) On July 28, four clarifiers, representing half of the plant's clarifier capacity, were
removed from service at 9:00 a.m. During the testing period, the final clarifier
^ ?
overflow rate averaged 59 m /day/m (1440 gpd/sq ft) based on a surface settling
area of 213 m2 (2,296 sq ft). The solids loading exceeded 171 kg/day/m2
(35 Ibs/day/sq ft) based on MLSS of 1,832 mg/1 and a recirculation ratio of 62%.
Effluent quality remained stable but then began to progressively deteriorate after
about 12 hours; TSS measurements on bihourly samples reached 78 mg/1 after 28
hours. A similar experiment was conducted on August 5 with virtually identical
results. These findings showed that there can be a considerable lag period (10-
12 hr) before the effects of a substantial increase in final clarifier overflow rate
are observed in the final effluent. However, as described above, previous testing
(particularly that conducted on March 10 in which the same clarifiers were taken
out of service under similar conditions) generally showed much shorter lag periods
before the effluent quality deteriorated. The difference is attributable to (a)
more efficient solids return in the later testing (because the clarifiers and sludge
return lines had been cleaned of blockages and deposits in the interim), and
(b) lower initial sludge levels in the clarifiers for the later testing periods.
44
-------
The final effluent data in Tables 3-6 along with the preceding discussion suggests that
the effects of flow equalization on the performance of this activated sludge system
were less important than the effects of other operational variables. First, plant
performance was similar under both equalized and unequalized conditions, even when
the final clarifiers were stressed. If anything, the performance of the plant, as
measured by the mean and variance of the bihourly effluent TSS and BOD data, was
marginally better when the flow was unequalized (See Table 3 and the corresponding
conditions of operation in Table 14). Second, there was continuing difficulty throughout
these studies in maintaining control over the operating conditions and this lack of rigid
control undoubtedly affected the effluent quality, irrespective of equalization. For
instance, there were problems in operating the Ypsilanti plant with a constant BOD
loading intensity. Likewise, there are various other factors which may affect effluent
quality, including sludge settleability, wind and density currents, recycle rate, sludge
blanket height, chemical dose (for P precipitation), etc. Not all of these variables could
be controlled at the plant nor would they be likely to be rigidly controlled at most
manually-operated plants. Therefore, without proper operational control, this study
indicated that benefits of flow equalization, if any, can be lost.
Another factor which would tend to minimize performance differences between
equalized and unequalized plants is the insensitivity with which final clarifiers appear to
respond to changes in flow rate, even at high hydraulic loadings. Figure 6 shows that
there was a time lag on the order of 12 hours before the effect of a substantial increase
in clarifier loading was observed in the effluent during one representative experiment at
the plant (See Item (7) above). Response times of this magnitude would act to diminish
any adverse impact of normal diurnal flow variations at a plant. Similar results were
observed in other runs, although as previously discussed the time lag was not always as
long as 12 hours before the effluent deteriorated. Based on our observations, variable
flows have limited impact on final clarification efficiency except where the solids
loading becomes limiting, causing a build-up in the clarif ier sludge inventory, raising of
the sludge blanket, and eventual carryover of solids.
A further indication that final clarifier performance is relatively insensitive to flow
variations is illustrated in Figure 7. Here, TSS concentrations in grab samples of
secondary effluent are plotted as a function of overflow rate at the time of sampling,
for samples collected under diurnal flow conditions. It is evident that the two variables

do not correlate very well, although there is some indication that the effluent TSS
deteriorated with overflow rates above 57 m3/day/m2 (1400 gpd/sq ft). These data
were subjected to linear and nonlinear regression analysis to determine if there was a
definite linear or log-log linear relationship between the effluent TSS concentration and
the instantaneous flow rate occurring at the time of sampling. Additional analyses were
also run for lag periods on flows of 1 hour and 2 hours to determine if effluent TSS
concentration was more strongly related to the flows 1 or 2 hours earlier. All
regression analyses indicated a lack of significance at the 5 percent level between
effluent TSS and flow.
Special Studies
Effects of Equalization on Wastewater Temperature
Temperature readings were taken on the influent and effluent of the equalization basins
over a period of several months at times when the basins were full or nearly full, i.e.,
when the retention time was greatest. Based on 131 daily measurements between June,
1974 and February, 1975, it was found that the equalization basin resulted in
temperature changes of the influent wastewater of less than 1°C. Influent wastewater
temperature varied from a monthly average of 20°C in August, 1974, to 11°C in
January, 1975. Sometimes the apparent effect of equalization was to increase the
temperature of the wastewater and sometimes to decrease it. Since the thermometer
used to take the measurements was only read to the nearest 0.5°C, we believe the
differences are largely explainable in terms of the low precision of measurement. The
conclusion reached is that the closed equalization basins at Ypsilanti Township had no
significant effect on wastewater temperature.
Aeration Requirements for Equalization
A brief study was performed to determine the minimum air flow rate necessary to both
maintain aerobic conditions and prevent sedimentation of solids in the equalization
basin. To facilitate the work and make it more generally applicable, only one of the
two equalization basins was used; the second tank was taken out of service by closing all
valves to the tank. Compressed air was fed to the first tank at rates of 4.2, 8.4, 13.0
and 16.8 m3/ min (150, 300, 460 and 600 cfm). After adjusting the air flow rate to the
48
-------
desired value, the D.O. concentration was aliowed to equilibrate at levels indicated in
Figure 8. Dissolved oxygen and TSS measurements were obtained at depths of 0.3, 3.4
and 6.4 m (1, 11 and 21 ft) below the water surface representing the top, midpoint, and
bottom of the tank. The tank was at full liquid depth (See Figure 2) and contained
1181 m (312,000 gal) of water at the time of the measurement which corresponded to a
theoretical detention time of about 4.2 hr. The samples and measurements were taken
through a manhole in the cover of the equalization basin about half way between the
center and periphery of the basin.
Results of the study are presented graphically in Figure 8. It was observed that sedi-
mentation of solids apparently occurred only at the lowest level of aeration (3.7x10
m /min/1, 0.5 cfm/1000 gal). Aerobic conditions prevailed throughout the basin even at
the lowest level of aeration, although the D.O. content decreased with distance from
the air nozzles, achieving a minimum of 2.3 mg/1 at a depth of 0.3 m (1 ft) below the
3
surface at an air flow of 4.2 m /min (150 cfm). These results indicate that the aeration
requirements for providing complete mixing are greater than for maintaining aerobic
conditions in an equalization basin. The minimum level of aeration for preventing solids
deposition was about 7.5 x 10~ m /min/1 (1.0 cfm/1000 gal) of storage.
Operational Problems During Study
The following operational problems were experienced in the equalized plant (Plant
No. 1) during the course of the study:
1. Rags and Debris ~ In the initial phase of the study, Plant No. 1 had no pretreat-
ment facilities. Therefore, rags and other debris tended to accumulate in the
aeration compartments and, eventually, the final settlers. These rags caused
problems in the operation of the return sludge system by plugging the sludge return
lines. This was remedied by installing a manually cleaned bar rack in the influent
channel.
2. Influent Metering There were a few occasions on which the influent magnetic
flow meter was inoperative.

caused by the interconnected sludge piping systems of the two plants which
severely limited operational control over sludge wasting.
4. Sampling Special sampling lines were installed so that most samples could be
taken at a sink inside the control building. Nevertheless, some problems with
plugged lines were encountered, and it was decided to collect all samples directly
at the sample point.
5. Ferric Chloride and Polymer Feed Systems ~ The ferric chloride and polymer feed
lines were subject to occasional plugging or freezing. Such problems were usually
corrected within a day.
6. Manpower Requirements There was insufficient manpower on the Ypsilanti
Township staff to rapidly respond to some of the non-routine duties and require-
ments inherent in plant-scale research. The function of the project research
personnel was mainly sampling and analysis, and they were limited in their ability
to carry out or assist in any aspects involving plant operations. Conversely,
treatment plant personnel were not able to assist in performing some of the
additional sampling and analysis that might have been desirable.
Cost Considerations
The actual construction cost for upgrading Plant No. 1 and providing flow equalization
is itemized in Table 15 according to the contractor's breakdown. The work consisted
principally of a) piping additions and deletions to convert existing primary clarifiers to
secondary clarifiers; b) grit chamber modifications; c) installation of a completely new
diffused air system for the aeration basins; and d) installation of equipment and
appurtenances necessary for converting existing digesters to equalization basins,
including an equalization pump, piping, control valving, compressed air system, and
instrumentation.
Costs associated with the equalization system were not itemized separately by the
construction contractor but have been estimated as shown in Table 16. The estimated

^Engineers estimate (EPA Cost Index 183).
-------
cost for the equalization facilities of $85,000 is only about 25% of the cost for
equalization that would have been experienced had new concrete equalization basins
been constructed.
Use of flow equalization at the plant was necessary to gain state approval for the
conversion of the primary clarifiers to secondary clarifiers. Thus, provision of flow
equalization was cost effective in this case because, in effect, it eliminated the need
for costly construction of new secondary clarifiers. In general however, flow
equalization would not be considered a substitute for primary sedimentation.
Operation and maintenance costs for the equalization system at Ypsilanti Township are
not monitored separately and are therefore difficult to estimate. It is the authors'
observation that a negligible amount of operator time is required on a day-to-day basis
for routine maintenance and operation. The only significant requirements will be for
periodic repair of equipment and control systems. After three years of operation at
Ypsilanti Township, the only equipment failure has been with the automatic valve
following the equalization pump.
The electrical power supply and electrical facilities operations at the Ypsilanti
Township Treatment Plant preclude the separation of power costs on a Plant No. 1 and
Plant No. 2 basis. Thus, a true power cost comparison of equalized and unequalized
flow conditions could not be made. However, the use of theoretical power associated
expressions for equalized and unequalized flow conditions indicated that the use of
flow equalization at Ypsilanti Township does not result in power cost economies.
Computations indicated that the savings in demand charges for aeration and return
sludge pumping brought about by equalization were slightly less than the added power
costs of the equalization pump and equalization basin blowers. Comparison of the
theoretical power costs for equalized and unequalized flows are shown in Table 17.

APPENDIX
MEASUREMENT OF DATA VARIABILITY
A large volume of bihourly and daily data was collected in this study. In analyzing these
data it was considered desirable not only to compare the average or mean values of the
waste parameters in different process streams, but also the variability or scatter of the
data used to compute the mean values. Three related measures of scatter were
employed, the variance, standard deviation, and coefficient of variation.
If Xp \2> X_ is a sample of n measurements having a mean of X, the standard
deviation S of the sample is defined by
S =
n
2
The quantity S , the square of the standard deviation S, is called the variance of the
sample. The coefficient of variation is simply the standard deviation S divided by the
mean X.
The standard deviation can be compared with the mean of the variable parameter to
provide an individual with a feeling of the degree of uncertainty associated with the
variable parameter. The variance allows the individual to ascertain the tightness of
data distributions; smaller values implying data distributions less widely spread about
the mean, greater values implying data distributions widely spread about the mean. The
coefficient of variation indicates the data scatter as a fraction of the mean and can
thus be used to compare the scatter of data having different mean values.

16. ABSTRACT
A plant-scale research program was carried out for more than a year to evaluate the
impact of flow equalization on the 14,000 m /day (3.7 mgd) upgraded activated sludge
plant at Ypsilanti Township, Michigan. Process streams were characterized under
both equalized and unequalized flow conditions with respect to BOD, COD, TSS and
forms of nitrogen and phosphorus.
The equalization system was effective in leveling influent diurnal flow variations
but was limited in its ability to dampen variations in wastewater concentration and
mass flux. Some biochemical action apparently occurred in the equalization basin,
although BOD removal was marginal and inconsistent. Analysis of secondary effluent
indicated that plant performance was similar with and without equalized flow,
suggesting that the theoretical advantages of flow equalization may not be achieved
in manually controlled plants. An examination of theoretical power costs for
equalized and tnequalized flow conditions indicated that the use of flow equalization
did not result in power cost economies.
