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 perservation
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.
As part of these activities, this case history report was prepared to
make available to the sanitary engineering community data on the operating
characteristics of a three cell, series, domestic wastewater treatment
lagoon and to present an evaluation of the data in relationship to the
original design criteria.

ABSTRACT
The wastewater lagoons at Eudora, Kansas, consist of three cells in series
and were placed into operation in May, 1972. These lagoons were designed
for a population of 4000, Currently, the sewered population of Eudora
is 2200. The lagoons were studied in detail from September, 1974, through
August, 1975. Analyses were made twice weekly for 8 months and daily for
4 months.
The results indicated the raw wastewater characteristics were normal for a
small residential community. The wastewater lagoons produced typical re-
sults with temperature having the greatest impact on the microbiology and
their biochemical reactions. The effluent quality from the treatment sys-
tem was determined primarily by the growth and suspension of the algae.
While the effluent BOD5 generally met the 30 mg/1 effluent criteria, the
effluent suspended solids concentrations far exceeded the 30 mg/1 criteria.
Removal of the effluent suspended solids would produce a well treated ef-
fluent with a high degree of removal of nitrogen and phosphorus as well as
BOD5.
This report was submitted in fulfillment of Contract 68-03-2059 by the
University of Kansas under the sponsorship of the Environmental Protection
Agency. Work was completed as of July 31, 1976.

SECTION I
INTRODUCTION
Lagoons have been widely used in the United States as low cost wastewater
treatment systems for both domestic sewage and industrial wastes. Because
of the simplicity of design and operation of lagoons little detailed operas
ing data are available as to the biochemical changes which occur in the
different lagoon systems or even as to the quality of effluent normally
expected from lagoons. Barsom and Ryckman^ examined the operational data
from a number of lagoons and concluded that lagoons were not adequate for
treating domestic sewage as far as effluent quality was concerned. The
EPA criteria for secondary treatment effluents from municipal plants stipu-
lated 30 mg/1 BODs and 30 mg/1 suspended solids. In view of the importance
of the sewage lagoons in wastewater treatment, a more detailed study of
oxidation ponds was initiated in order to find out the biochemical reac-
tions which occur in the various lagoon cells.
It was believed that detailed study of a typical sewage lagoon over a
full year would yield data on the seasonal variations which could be ex-
pected. It was also hoped that the data could be correlated to the theory
which had developed by experience over the years. Overall, the data should
yield a better understanding of the design of sewage lagoons,
Editorial Note
The definitions of secondary treatment for federal regulation of municipal
wastewater treatment plant effluents has been or is being modified. The
Federal Register Vol. 41, No. 144, Monday, July 26, 1976, pp. 30786-30789,
contains amendments pertaining to effluent values for pH and deletion of
fecal, colifortn bacteria limitations from the definition of secondary treat-
ment. The Federal Register Vol. 41, No. 172, Thursday, September 2, 1976,
contains proposed changes in the suspended solids requirements for small
municipal lagoon systems serving as the sole process for secondary treatment
of wastewaters.
-------
SECTION II
CONCLUSIONS
The major conclusions reached from this study were as follows:
1. This 3 cell wastewater lagoon could not meet EPA
effluent criteria for secondary treatment because of
excessive suspended solids in the final effluent.
2. Living and dead algae are primarily responsible for
the high effluent suspended solids.
3. Most of the waste organic stabilization took place in
Cell 1 with algae recycling nutrients in Cell 2 and
Cell 3.
4. Recycling of nutrients by algae results in a slow but
steady reduction of nitrogen and phosphorus in the ponds.
5. Temperature was the major factor affecting the growth
and predomination of the various species of bacteria and
the die-off of fecal coliform bacteria.
6. If the suspended solids could be removed from the final
effluent, it would meet EPA effluent criteria.
-------
SECTION III
RECOMMENDATIONS
It is recommended that studies be expanded to find a simple, economic
method for removing the suspended solids from the final effluent as this is
the key to meeting EPA effluent criteria. Further studies on the protozoa
and algae as well as bacteria would also lead to a better understanding of
the population dynamics of wastewater ponds.

SECTION IV
DESCRIPTION OF LAGOONS
The lagoon system used in this study was located in Eudora, Kansas and
consisted of three cells operated in series. A schematic diagram of the
lagoon system is given in Figure 1. The lagoons were designed to treat
the sewage from a population of 4000 people and had considerable flexi-
bility for the order of operation. During this study the lagoons were
operated as follows:
1. the raw sewage was pumped to a splitter box and discharged into
Cell 1 which had an area of 3.16 hectares (7.8 acres);
2. the discharge from Cell 1 flowed by gravity to Cell 2 which had
an area of 1.50 hectares (3.7 acres);
3. the discharge from Cell 2 flowed by gravity to Cell 3 which had
an area of 3.16 hectares (7.8 acres); and
4. the final effluent flowed by gravity to the Wakarusa River.
The lagoons were normal earth dike lagoons having 3:1 side slopes. The
operating liquid depth was maintained at 1.5 meters (5 feet) by a 45° £
V notch weir at the discharge point from Cell 3. There was approximately
1 meter (3 feet) of freeboard from the water level to the top of the dikes
around the lagoons. The side slopes above the water were seeded in grass
and mowed at regular intervals. No special precautions were taken to
protect the dikes at the water level. Normal wind action did cause some
erosion but it was not serious during this study. Wind was the normal
mechanism used for mixing the contents of the lagoons.
The sewage was pumped to the lagoons from a small pump station. The pump
cycle required about 3.3 minutes to empty the wet well. Two 45.4 I/sec
(700 gpm) centrifugal pumps were designed to handle peak flow with peak
infiltration. Only one pump was used during normal operation and it
operated well below design capacity.
The design BOD5 loading rate was 38.1 kg/ha (34 Ibs/acre/day). The overal
design loading was 308 kg (680 Ibs) BOD5/day. While the basic design flow
was 17.4 1/s (400,000 gpd), the system was designed to handle peak flow and
infiltration rates of 87 1/s (2.0 MGD).

SECTION V
EXPERIMENTAL PROCEDURES
SAMPLING LOCATIONS AND TECHNIQUES
In order to examine the lagoon contents as well as the raw waste charact^
eristics, four sample points were carefully selected. The raw waste
sample was collected at the splitter box. The cell samples were collected
at the three effluent structures since they protruded out into each cell.
All samples collected during this study were grab samples taken around
10 AM and were representative of the average conditions. It was planned
to use composite samplers but the problem of local vandalism prevented
the use of the composite samplers. Careful study of the waste character-
istics at Eudora indicated that sampling around 10 AM produced essential-
ly the same characteristics in the raw wastes as could be obtained with
composite samples. The cell samples were subject to so many uncontrolled
variables that there was little difference between grab samples and com-
posite samples.

SECTION VI
RESULTS
The large numbers of samples and analyses produced some real problems in data
handling and evaluation. In order to simplify handling the data, a decision was
made to present all of the data in Appendix A and to present only the monthly
averages in the body of the report. It was felt that monthly averages gave more
meaningful results since variations in wind action produced significant differ-
ences in mixing conditions. The monthly averages of the operating data are
shown in Table 2.
FLOW DATA
The raw wastewater flow pattern at Eudora was typical for the midwestern part of
the United States. The flow averaged 6.26 1/s (0.143 MGD) in September, 1974,
and dropped to 5.13 1/s (0.117 MGD) in January, 1975. The cold weather resulted
in the lower flows in December and January since the soil moisture in the upper
layer was essentially frozen. The warming weather in February resulted in thaw-
ing of the soil moisture and an increase in infiltration with a jump in flow to
7.97 1/s (0.182 MGD). Even though the rainfall increased during the spring
months the wastewater flow slowly decreased. The soil was able to retain much
of the rainfall with normal runoff accounting for the remainder. Minimum flow
was reached in July, 4.51 1/s (0.103 MGD). The average flow for the 12 month
period of this study was 5.87 1/s (0.134 MGD).
Converting the daily flow to a per capita basis gave an average flow of 0.0026
1/s (61 gpd) with a maximum daily flow of 0.0040 1/s (93 gpd) and a minimum
daily flow of 0.0018 1/s (42 gpd). The flows were typical for a small rural
community but the daily variations were lower than normally found in this size
system, ranging from a minimum of about 50% to a maximum of 150%. The varia-
tions during the day followed normal diurnal patterns. Since all flows were
pumped to the ponds, the flow pattern was characterized by a rapid discharge of
61 1/s (980 gpm) for 3.3 minutes and then1a wait until the wet well refilled.
During peak flow rates the discharges occurred frequently. The ponds tended to
level out the flow variations so that the discharge from Cell 3 was essentially
constant over short periods.
Unfortunately, it was not possible to measure the discharge from Cell 3 over
the entire period. The problem of vandalism at the lagoon site prevented in-
stallation of the effluent recorder until near the end of the project. The ef-
fluent data are recorded in Table A-2. The data collected during July and
August reflected the period of high evaporation. Maximum evaporation occured
the first part of July when 425,000 I/day (112,000 gpd) was lost by evaporation
and seepage. It was not possible to separate seepage from evaporation. Need-
less to say, rainfall produced a significant increase in the discharge and was
the major cause in any abrupt increase in effluent flow.

-------
One by-product of the effluent flow measurements was the ability to note signi-
ficant wind effects. The wind action over the surface of the pond surface
produced waves which affected the float movement and produced an oscillation on
the recorder. The magnitudes of the oscillations were in proportion to the wind
velocity over the pond surfaces.
pH AND ALKALINITY
The pH and alkalinity have long been used as parameters for wastewater pond
operations. The metabolism of organic matter in the absence of adequate oxygen
results in the production of organic acids and a depression of the pH. The
organic acids tend to be titrated in the alkalinity determination so that the
alkalinity appears to increase even though the pH is decreasing. Nitrification
can also produce a depressed pH but alkalinity is also destroyed. Thus, the pH
and alkalinity measurements can indicate which of these two reactions is occur-
ring. Under aerobic conditions the bacterial metabolism tends to cause the pH
to increase along with an increase in alkalinity. The ammonia released from
the protein metabolism reacts with carbon dioxide and water to form ammonia bi-
carbonate.
The algae also affect the pH in the ponds. Synthesis of new algae cells re-
quires carbon dioxide either directly or from alkalinity. Removal of carbon di-
oxide results in a rise in pH with a shift in the form of alkalinity. The shift
in alkalinity is indicated in the following equation.
2(NH4)HC03 + algae 1:LSht:;> more algae + (NH ) CO -ffi.0 + 0
^ ^ J Lt £
The carbonate alkalinity formed by the metabolic reaction is the same as the
original bicarbonate alkalinity but the pH is higher.
Examination of the PH data in Tables 2 and Table A-3, indicates that the PH of
the raw wastewaters varied between 7.3 and 8.0, averaging 7.7 for the year.
The pH in Cell 1 decreased from 8.2 in September to 7.8 in November. The pH re-
mained at 7.8 until March when it jumped to 8.5 as the result of a sudden bloom
of algae. The PH decreased to 7.9 in May and then jumped again to 8.5 in June.
The pH was 8.1 in August. In effect, the initial decrease in PH was the direct
result of slowing metabolism at the start of the fall period. The cold weather
kept metabolism down and the pH reflected the low rate of metabolism. The algae
blooms in March and June were clearly reflected in the pH data.
The pH in Cell 2 averaged 8.4 and showed similar trends as in Cell 1. The pH
fell with the onset of cold weather and rose with the periodic algae blooms.
The pH in Cell 3 was the highest, averaging 8.8. The pH in Cell 3 ranged from
8.4 to 9.1. At no time did the pH rise sufficiently to be toxic.
The alkalinity data are presented in Tables 2 and A-4. It can be seen that the
alkalinity in the raw wastewaters were relatively constant until the dry period
in July and August. The alkalinity measurements on the raw wastewaters in-
cluded organics and phosphates as well as normal bicarbonate alkalinity. The
Impact of the organics in the raw wastewaters is clearly evident in the alkalin-
ity change from the rat; wastevaters to Cell 1. The alkalinity in Cell 1 aver-
aged 320 mg/1 and ranged from a low of 250 mg/1 to a high of 360 mg/1.
24
-------
Maximum alkalinity in Cell 1 was reached in January when metabolism was low and
was a minimum in July. The other two ponds followed the same trend in alkalin-
ity with Cell 2 averaging 280 mg/1 and Cell 3 averaging 240 mg/1. The drop in
alkalinity through the 3 cells is the result of some phosphate reduction and
some organic reductions. There may have been some calcium precipitation but
the pH was not high enough for much precipitation. Removal of phorphorus by
metabolism and settling of the microbial cells could have produced the changes
observed in the alkalinity data.
TEMPERATURE AND DISSOLVED OXYGEN
The temperature of the ponds are presented in Tables 2 and A-5. The data re-
flect the seasonal variations in temperature. The raw wastewaters averaged
17°C with monthly averages ranging from a low of 12°C in January and February
to a high of 24°C in August, All three ponds had essentially the same temp-
eratures, averaging 15°C for the year. The minimum monthly temperature was
2.9°C in February with the maximum monthly temperature reaching 27°C in July.
This wide range of temperature had a very pronounced effect on the microbiology
and biochemistry of these three cells.
The dissolved oxygen data are tabulated in Tables 2 and A-6. The dissolved
oxygen in the wastewater ponds is the result of algal metabolism, surface aera-
tion and bacterial metabolism. The algae release oxygen as a result of their
metabolism while bacteria use oxygen in their metabolism. Surface aeration can
result in loss of oxygen from the pond if the surface is supersaturated with
oxygen or can result in additional transfer to the pond if there is a deficit
at the surface. The dissolved oxygen in the raw wastewaters was essentially
zero due to the prolonged retention in the wet well prior to pumping to the
ponds.
The dissolved oxygen in Cell 1 varied between 1.8 mg/1 in July and 15 mg/1 in
March on a monthly average and gave an annual average dissolved oxygen of 6.0
mg/1. The lowest DO values occured during the cold weather when there was
little algae growth and ice covered the ponds part of the time and during the
hot weather when the temperature was the highest. The dissolved oxygen was
higher in Cell 2 than in Cell 1, reflecting the lower bacterial demand and the
additional algae growth. The annual average DO in Cell 2 was 9.5 mg/1 with
monthly averages ranging from 3.6 mg/1 in July to 16 mg/1 in February. Cell 3
showed slightly higher DO levels than Cell 2, averaging 11 mg/1 with a low of
4.2 mg/1 and a high of 19 mg/1. Dissolved oxygen is not a problem in the total
system although Cell 1 approaches very low DO values.
Special samples indicated the DO tended to decrease with depth and reached zero
at the bottom of each cell. Wind mixing was important in the vertical distri-
bution of DO in each cell. With good wind mixing there was little DO differ-
ences from the surface to the bottom of each cell. The bottoms of all cells
were always at zero DO.
BIOCHEMICAL OXYGEN DEMAND
The 5 day Biochemical Oxygen Demand test is still one of the most important
25
-------
measurements for determining effluent quality from any wastewater treatment
system. The raw wastewaters showed a variable BOD5 concentration averaging
270 mg/1 with a monthly minimum of 180 mg/1 in June and a monthly maximum of
400 mg/1. The BOD5 data are given in Tables 2 and A-7. Approximately half of
the BOD5 in the raw wastewaters was soluble, averaging 140 mg/1. The BOD data
indicated the sewage was close to normal for a small residential community.
The BOD5 in Cell 1 averaged 49 mg/1 total BOD5 and 14 mg/1 soluble BOD. In
effect, 90% of the soluble BOD5 was removed in Cell 1. The BOD5 data indicated
the impact of the microbial solids. Cell 2 dropped the total BOD5 to 36 mg/1
with 7.9 mg/1 soluble 8005. The major factor in the 6005 results were the algae
since little organic matter was available for the bacteria in Cell 2. Cell 3
averaged 24 mg/1 BOD5 with only 4.0 mg/1 soluble BODc. There was little varia-
tion in the soluble effluent BOD5, 1.8 mg/1 to 7.0 mg/1. The total effluent
BOD5 ranged between 15 mg/1 and 34 mg/1. Minimum effluent quality occurred in
the cold weather when algae growth was low and the ponds were covered with ice.
The reduced mixing in the ponds permitted the algae to settle out.
CHEMICAL OXYGEN DEMAND
The Chemical Oxygen Demand (COD) is a measure of the total organics both bio-
degradable and non-biodegradable. The COD data are presented in Tables 2 and
A 9-10. The COD of the raw wastewaters averaged 560 mg/1 with a monthly mini-
mum of 380 mg/1 in May and a maximum of 640 mg/1 in both September and March.
The soluble COD average 210 mg/1, indicating that most of the COD in the waste-
waters was related to the suspended solids. The monthly averages for the COD
varied from 120 mg/1 to 280 mg/1.
The COD in Cell 1 averaged 200 mg/1 with 73 mg/1 soluble COD. In view of the low
soluble BOD5 in Cell 1, it is apparent that there is some non-biodegradable COD
in solution, normal for most biotreatment systems. This is confirmed by the
slight soluble COD decrease through Cells 2 and 3. There are very little bio-
degradable organics left in the final effluent even though the soluble COD
averaged 52 mg/1. The total COD dropped to 160 mg/1 in Cell 2 and to 130 mg/1
in Cell 3. The COD data indicated considerable suspended solids which were
slowly biodegradable.
SUSPENDED SOLIDS
The suspended solids concentrations are given in Tables 2 and A-ll-12. The
average suspended solids in the raw wastewaters was 280 mg/1 with 220 mg/1
volatile suspended solids. It appears that the suspended solids are normal for
domestic sewage, averaging 79% volatile matter. Maximum suspended solids occur-
red in July and August while minimum suspended solids occurred in May. It is
obvious that the high rainfall in May produced dilution without carrying soil
particles as occurred in the early spring with the thaw. Probably all tiny
particles easily carried into the sewers were already removed by May. The COD
data reflected the early runoff as well as the suspended solids data.
The three cells showed a progressive decrease in suspended solids dropping from
an average of 110 mg/1 in Cell 1 to 88 mg/1 in Cell 2 and 67 mg/1 in Cell 3.
26
-------
At no time did the final effluent meet current EPA criteria for 30 mg/1 sus-
pended solids on a monthly average. The suspended solids are largely living
and dead microorganisms. The percentage volatile suspended solids increased
through the 3 cells from 84% in Cell 1 to 86% in Cell 2 to 88% in Cell 3. This
change is typical for biotreatment systems having dispersed microbial popula-
tions and essentially a soluble organic substrate.
PHOSPHORUS
The change in phosphorus is very important since phosphorus is a key nutrient
in the growth of microbial cells. The phosphorus data are shown in Tables 2
and A-13. The phosphorus in the raw wastewater averaged 18 mg/1, higher than
normal but reasonable for the lower flow and higher organic concentrations.
The phosphorus dropped to 9.6 mg/1 in Cell 1, to 6.7 mg/1 in Cell 2 and to
3.9 mg/1 in Cell 3. It appeared that the phosphorus reduction was related to
the microbial metabolism reactions after the initial settling which occurred
in Cell 1. Maximum phosphorus concentrations occurred in February in all 3
cells. The accumulation of phosphorus was the result of the low temperatures
slowing metabolism. The increased temperature in March stimulated microbial
growth and a sharp drop in phosphorus. These data indicate that the ponds are
reasonably effective in reducing the phosphorus in the wastes. When the impact
of evaporation is considered, the reduction in phosphorus is greater than in-
dicated by the concentration data.
NITROGEN
Nitrogen is a key nutrient in microbial metabolism the same as phosphorus. The
raw wastewaters contain organic nitrogen and ammonia nitrogen which can undergo
changes as a result of microbial metabolism. Initial reactions tend to convert
the organic nitrogen in the raw wastewaters to ammonia nitrogen. Some of the
ammonia nitrogen is processed into organic nitrogen in the form of microbial
cells. Under aerobic conditions some of the ammonia nitrogen can be oxidized
to nitrites or even to nitrates. The nitrogen data are given in Tables 2,
A-16 and A-17. The Kjeldahl nitrogen measurements include both organic
nitrogen and ammonia nitrogen. The Kjeldahl nitrogen concentration in the raw
wastewaters averaged 51 mg/1 with a minimum of 43 mg/1 and a maximum of 68 mg/1.
Approximately half, 25 mg/1 of the Kjeldahl nitrogen was ammonia nitrogen. The
Kjeldahl nitrogen dropped to 21 mg/1 in Cell 1 with 9.3 mg/1 ammonia nitrogen.
The change in ammonia nitrogen reflects microbial metabolism. Cell 1 showed
some nitrites in the late fall and considerable nitrites in November. The nit-
rate nitrogen averaged 1.9 mg/1 in Cell 1 with quite a variation with time and
temperature.
Cell 2 showed a drop in Kjeldahl nitrogen to 14 mg/1 with 4.8 mg/1 ammonia
nitrogen. There were some nitrites in the spring and in the fall. The nitrate
nitrogen averaged 1.4 mg/1 with peaks in November and May. Cell 3 had 9.0 mg/1
Kjeldahl nitrogen, 1.1 mg/1 ammonia nitrogen, and 0.7 mg/1 nitrate nitrogen.
It appears that ammonia nitrogen approached zero during the summer and the fall,
limiting further microbial reaction. When ammonia nitrogen dropped to a mini-
mum in the summer, the microbes reduced a portion of the available nitrates.
Nitrification occurred slowly with time and temperature important in the build
up of the nitrifying bacteria.
27
-------
COLIFORMS
Coliform analyses were made for both total conforms and fecal conforms. The
coliform data are given in Tables 2 and A-18 and A-19. The total coliforms in
the raw wastewaters were normal having an annual average of 9.4xl06/100 ml with
monthly median values from 4.1x106/100 ml to 24xl06/ml. The fecal coliforms
averaged 2.6xl06/100 ml with a range from 0.9x106/100 ml to 4.3x100 ml. The
fecal coliforms were approximately one fourth of the total coliform population,
which is consistent for normal domestic wastewaters.
There was a definite reduction in coliforms through the three ponds. Both the
total coliforms and the fecal coliforms dropped to 240,000/100 ml and 32.000/
100 ml, respectively, in Cell 1. The drop in coliforms can be related to normal
predation by higher animals and die off as a result of competition for food.
The reduction in coliforms through Cell 2 and Cell 3 is as anticipated when one
considers the retention period with little food available for growth and normal
competition with other bacteria. The final effluent showed a low coliform count
with maximum reduction occurring in the warm summer period when competition and
predation were a maximum. The highest effluent coliform counts occurred in
the winter months when microbial activity is a minimum due to the lower tempera-
ture.
ALGAE, PROTOZOA AND HIGHER ANIMALS
The algae and the protozoa, together with higher microscopic animals are import-
ant to the success of any oxidation pond system. It has long been recognized
that bacteria stabilize the organic matter in the wastewaters with algae and
protozoa being secondary organisms. The algae utilize sunlight for their energy
source and metabolise the inorganic components in the liquid to form new cells.
One end product of algae metabolism is oxygen which the bacteria use to maintain
aerobic metabolism. While the oxygen from algae metabolism is available for the
bacteria to use, the growth of algae results in the production of additional or-
ganic suspended solids which must be considered in the overall treatment process.
A very heavy algae growth can actually increase the suspended organic solids
over that entering the ponds with the raw wastewaters. The protozoa and the
higher microbial animals can help reduce the bacteria and the algae populations
by metabolism. Since very little information was available concerning the
quantitative relationships on the growth of algae in wastewater ponds, an effort
was made to determine the growth of the major species of algae. Only qualitative
measures of protozoa and higher animals was possible in this study. The data on
the algae and the microscopic animals are given in Tables 2 and in Table A-20
through A-39 in the Appendix.
Green, Non-Motile Algae.
The green, non-motile algae were the predominant type of algae in these ponds
with Scenedesmus. Chlorella, Actinastrum, Ankistrodesmus. and Microactinium
being the major families. No effort was made to differentiate species although it
was recognized that several different species occurred. Scenedesmus occurred
in all ponds all year round with greater growth in Cell 1 than in Cells 2 and 3.
The increased numbers of Scenedesmus in the winter came about from the fact that
Scenedesmus tended to fragment. Normally, a Scenedesmus consisted of four cells
28
-------
in normal clusters. During the winter the Scenedesmus fragmented into one and
two cell fragments. Each clump was counted as a simple count rather than as
to the number of individual cells. Chlorella also grew best in the pond with
the most nutrients, Cell 1. Peak growth occurred in March when each milliliter
of water in Cell 1 contained a median of 2.8xl06 Chlorella. Chlorella were
readily metabolised by the protozoa and the higher animals and quickly dropped
as the temperature increased, stimulating greater animal growth. Actinastrum
and Ankistrodesmus predominated in the summer and fall and dropped out during
the cold weather. Microactinium were able to grow only during the early spring
when temperature and nutrients favored successful competition.
Green Motile Algae.
The green motile algae have an advantage over the non-motile algae in their abil-
ity to move to the point of optimum nutrient and energy concentrations. The
major groups of green motile algae observed in these ponds included Chlamydom-
onas, Euglena, Phacus, Carteria, Chlorogonium and Pandorina. The Chlamydomonas
tinned to increase in the fall and the spring but were present all year long.
Euglena dropped out of Cell 1 in November and December when cold weather first
'set in but increased rapidly with warm weather. Yet in Cells 2 and 3 there was
good growth in the cold months. It appears to be more a case of available
nutrients than temperature alone. Phacus grew best during the winter months and
dropped out when the temperature increased in the spring and summer. On the
other hand, Carteria predominated in the spring and fall in Cell 1 with extension
into the winter in Cell 3. It appeared the Chlorogonium liked the warm weather.
Pandorina was noted only in the fall in the first two cells As a rule, the
motile green algae grew slightly better in Cell 2 than in the other two cells.
Blue-Green Algae. . , , , _, ,
One concern with wastewater ponds is the growth of blue-green algae. These al-
gae tend to form clumps and float to the surface, creating a scum which prevents
light transmission and oxygen transfer into the body of the pond. Adverse en-
vironmental conditions soon result if the blue-green algae persist. Oscillator-
ia was the major blue-green algae in this system. Oscillatoria formed short
filaments which were motile. These filaments were composed of many separate
cells. The counting procedure resulted in a filament count even though the
length of the filaments varied considerably. The Oscillatoria tended to grow
better in Cell 3 than in Cell 2 or Cell 1. In all cells, the Oscillatoria grew
best in the warm weather and essentially dropped out in the very cold veather
Anacvstis and Agmenellum also grew best during the warm weather. Only in Cell 1
was there any blue-green algae scum. The high populations during the summer
months tended to permit scum formation composed of Oscillatoria and Anacystis.
The surface tension differences between Cell 1 and Cell 2 appear to make a
difference in scum formation since the blue-green algae population was essenti-
ally the same in both cells. At no time was there noticable scum in Cell 3.
Wind action and rain were important in reducing the magnitude of the scum on
Cell 1. Good wind action quickly moved the scum to the edge of the pond and
slowly broke it up by wave action.
Yellow-Brown Motile Algae. /•.,.„„«.„
The yellow-brown motile algae consisted of Cryptomonas and Mallomonas. gy^
monas tended to grow best during the cooler periods when the other algae did not
29
-------
grow as well. Growth was best in Cell 3 indicating competition with other
algae had an important effect on the Cryptomonas. Mallomonas was most notice-
able in the fall and spring. The yellow-brown algae were never a major group
but were definitely a factor in the overall algae population.
Diatoms.
Diatoms grew readily in these ponds with Nitzchia being in sufficient numbers
to permit differentiation from the other diatoms. Nitzchia grew best in the
spring and fall with few in the winter. The same pattern was followed by the
other diatoms. The diatoms tended to grow best in Cells 1 and two where nut-
rients were high.
Protozoa and Higher Animals.
The free swimming ciliated protozoa were present in large numbers in Cell 1
with decreasing populations in Cells 2 and 3. It was interesting to note the
protozoa were the densest in the spring and fall. Rotifers and Cyclops were
^!ecP^Sent 5r!m '?"%*?,tlme- Large numbers of rotif ers were observed in
the spring and in the fall. Cyclops also occurred most in the spring and in
the fall. The rotifers and Cyclops tended to predominate more in Cell 3 and
helped reduce the excess microbes in the effluent. Few higher animals were
noted in July and August. The diurnal variation in dissolved oxygen in the
summer.appeared to have an adverse effect on the growth of the protozoa and
the higher animals. With lower temperatures and lower rates of metabolism
the microscopic animals found the environment suitable for good growth.

SECTION Vll
DISCUSSION OF RESULTS
The data collected at Eudora, Kansas, followed typical patterns for a small
tnldwestern community with essentially residential wastewaters. The only in-
dustry of any size in Eudora was a small, custom slaughterhouse which handled
a few animals on request from local farmers. The amount and characteristics
of wastewater from this plant did not have any adverse effect on the waste
characteristics.
The flow of 0.0026 1/s (61 gpcd) per person and an average BOD5 of 270 mg/1
gave a daily per capita BODs production of 60.6 gms (0.13 Ibs/c/d). The per
capita suspended solids production was 62.9 gms (0.14 Ibs/c/d). Both of these
values are normal for a small community. The design criteria of 0.0043 1/s
(100 gpcd), DWF, was considerably larger than needed. The organic load design
criteria, 77 gms/cap./day (0.17 Ibs/c/d) was also conservative. These factors
combined to produce a treatment system 64 percent larger than needed based on
flow and 27 percent larger than needed based on BOD5 applied.
Two interesting factors which affect wastewater ponds which do not affect other
treatment processes to the same extent are rainfall and evaporation. The 34
inches of rainfall during the study period is close to normal. Direct rainfall
on the water surface added 67.0xl06 liters (17.9 million gallons) to the three
ponds. The total wastewater flow was only 195x10° liters (52.2 million gallons)
Since rainfall did not occur uniformly over the time period of this study, the
impact was varied and hard to ascertain directly. A one inch rainfall during
the spring had a different effect than a one inch rainfall in the late summer.
The V notch weir on the discharge from Cell 3 controlled the variations in
flow to a large extent. Since the quantity of extra flow created by the one
inch rainfall was the same, the primary difference was in the time period over
which the extra flow was discharged. In the spring the extra flow was dis-
charged faster than in the summer.
Evaporation results in removal of water without corresponding removal of con-
taminants. Normal evaporation in this area averages 47 inches/year. The
removal of 92.6xl06 liters by evaporation exceeded the amount added by rainfall.
The difference is compounded even more when one considers that rainfall and
evaporation occur at different times during the year. Overall, evaporation re-
sults in the loss of 13% of the wastewaters entering the ponds. Seepage re-
sults in an even greater loss. The loss of water by evaporation makes precise
evaluation of seepage losses difficult.
The BOD5 and the COD data are useful in evaluating the characteristics of the
raw wastewaters as well as of the three ponds. Fundamental concepts indicated
that the 5 day BOD of wastewaters is approximately 0.58 times the biodegradable
COD. Using the data for the raw wastewaters, it was found that the biodegrad-
31
-------
able COD was 470 mg/1 based on the total sample and 240 mg/1 based on the sol-
uble samples. These data indicated that 90 mg/1 of the COD was non-biodegrad-
™le of? a11 the soluble COD bei°8 biodegradable. Of the 350 mg/1 suspended
COD, 26£ was not biodegradable. In Cell 1 the biodegradable COD dropped to
84 mg/1 with 24 mg/1 in solution. The non-biodegradable COD was 110 mg/1 with
49 mg/1 in solution. The 61 mg/1 non-biodegradable suspended COD reflected
the large number of dead microbial cells; 48 percent of the volatile suspended
solids in Cell 1 were inert.
The biodegradable COD dropped to 62 mg/1 in Cell 2 with 14 mg/1 in solution.
The non-biodegradable COD averaged 100 mg/1 with 48 mg/1 in solution. The non-
biodegradable suspended COD was 52 mg/1, 53 percent of the volatile suspended
solids. In Cell 3, the biodegradable COD dropped to 41 mg/1 with only 7 mg/1
in solution. The non-biodegradable COD was 90 mg/1 with 45 mg/1 in solution.
The non-biodegradable suspended COD was 45 mg/1, 58 percent of the volatile
suspended solids. It was interesting to note that all of the soluble organics
in the raw wastewaters were biodegradable and the soluble organics in the three
ponds had a fairly constant concentration of non-biodegradable organics, 45-49
mg/1 as COD. It has been noted that biotreatment systems tend to produce a non-
biodegradable, soluble, organic residue. This material is probably related to
the slime layer washed from the cells or released as a result of protozoa and
higher animal metabolism.
These COD and BOD relationships reflect the biochemical changes occurring in
the three ponds. The major stabilization reaction occurred in Cell 1 with
little reaction other than endogenous respiration occurring in Cells 2 and 3.
If the microbial solids could be removed from the first pond, the effluent
quality would be satisfactory for discharge. Cells 2 and 3 simply hold the
microbes so they can undergo endogenous respiration. The decrease in coliform
bacteria showed the effect of starvation and predation. These bacteria found
the ponds unsuitable and slowly died off. The extra two cells helped produce
significant die off of the coliform bacteria and helped produce an effluent
close to the 200 fecal coliform/100 ml.
With a theoretical retention time slightly over one year based on flow less
evaporation, the algae had a real opportunity to grow, die off, and to repeat
the cycle many times over. In effect the nutrients were slowly turned over with
each pond developing its own dynamic population of mixed microbes. Temperature
and nutrients seemed to play the greatest role in selection of the various graup
of microorganisms. It was interesting to note the explosion in Chlorella in
the early spring. The small size of the Chlorella gave them a distinct advant-
age as the temperature warmed up. Their growth then stimulated the protozoa
and the higher animal predators. The metabolism of the Chlorella let other
algae compete for the nutrients. The different growth patterns clearly re-
flected the dynamic aspects of the ponds.
The growth of the algae required nitrogen, phosphorus and carbon. The changes
in these three elements which occurred in the ponds reflects the growth of the
algae. When the algae die, s. part of the cell tissue undergoes lysing with a
return of nutrients to the liquid but a part of the cell tissue remains inert
and settles out. The dead cell tissue contains some nitrients and is the
primary mechanism for the removal of the nutrients from the wastewaters. The
32
-------
long retention period of these three ponds permitted excellent Deduction in
nutrients, 81 percent of the total nitrogen and 78 percent of the P^«<«-
The importance of the algae growths to the nutrient reductions is shown by the
S«S? nS?i«? rSScSl&is in the summer than in the winter. The warmer temp-
erature stimulates faster growth-death cycles and a «r«5er_*^ *£™£*-
ents. It appeared in this system that nitrogen became the Uniting nutrient
for a few days during the summer. The alkalinity supplied the needed carbon
for growth. As carbon was taken up, the pH and the dissolved oxygen both in-
creased There was enough alkalinity and carbon dioxide that the PH did not
rise nigh enough To slow down metabolism or precipitate significant quantities
of phosphate.

16. ABSTRACT
The wastewater lagoons at Eudora, Kansas, consist of three cells in series and
were placed into operation in May, 1972. These lagoons were designed for a population
of 4000. Currently, the sewered population of Eudora is 2200. The lagoons were
studied in detail from September, 1974, through August, 1975. Analyses were made twice
weekly for 8 months and daily for 4 months.
The results indicated the raw wastewater characteristics were normal for a small
residential community. The wastewater lagoons produced typical results with temper-
ature having the greatest impact on the microbiology and their biochemical reactions.
The effluent quality from the treatment system was determined primarily by the growth
and suspension of the algae. While the effluent 6005 generally met the 30 mg/1
effluent criteria, the effluent suspended solids concentrations far exceeded the
30 mg/1 criteria. Removal of the effluent suspended solids would produce a well
treated effluent with a high degree of removal of nitrogen and phosphorus as well
as BOD5.
