                 RESEARCH REPORTING SERIES

 Research reports of the Office of Research and Development, U.S. Environmental
 Protection Agency, have been grouped into nine series. These nine broad cate-
 gories were established to facilitate further development and application of en-
 vironmental technology. Elimination of traditional grouping was consciously
 planned to foster technology transfer and a maximum interface in related fields.
 The nine series are:

      1.  Environmental Health Effects Research
      2.  Environmental Protection Technology
      3.  Ecological Research
      4.  Environmental Monitoring
      5.  Socioeconomic Environmental Studies
      6.  Scientific and Technical Assessment Reports (STAR)
      7.  Interagency Energy-Environment Research and Development
      8.  "Special" Reports
      9.  Miscellaneous Reports

 This report has been assigned to the ENVIRONMENTAL PROTECTION TECH-
 NOLOGY series. This series describes research performed to develop and dem-
 onstrate instrumentation, equipment, and methodology to repair or prevent en-
 vironmental degradation from point and non-point sources of pollution. This work
 provides the new or improved technology required for the control and treatment
 of pollution sources to meet environmental quality standards.

                              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.

                       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).

                            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.

                                    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

 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.

 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.

                             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

 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.
