Operation Report on
American Hospital Supply Sewage Treatment Plant
N.W. 97th Avenue and 25th Street
Miami, Dade County, Florida
March 11, 1971
INTRODUCTION
The American Hospital Supply Sewage Treatment Plant was inspected
and sampled on January 14, 1971, by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant consists of a Davco Contact Stabilization package unit with
tertiary filters and chlorination prior to discharge to the NtW. 25th
Street Canalo
SUMMARY AND CONCLUSIONS
Removal of BOD equalled 93.27o with 5.2 mg/1 being measured in the
effluent.
An influent settleable solids level of .2 ml/1 was reduced to zero
in the effluent. Total suspended solids removal efficiency equalled
257o producing art effluent concentration of 12 mg/1.
The chlorine residual was measured at 2 ppm in the dosing tank
prior to discharge.
It is recommended that the low solids removal efficiency be
investigated.

6. Tertiary filters.

RESULTS
Removal of BOD5j COD and TOC equalled 93.2, 70.9 and 89.67.
respectively, leaving effluent concentrations of 5.2, 39 and 13 mg/1.
Based on the actual flow of 30,000 GPD, the corresponding loads were
calculated as 1.3, 9.76 and 3.25 lbs. per day.
Solids efficiencies were significantly diverse. Settleable solids
were removed with 1007o efficiency while total suspended solids were
removed with 25% efficiency. The total suspended solids influent
concentration of 16 mg/1 was only reduced to 12 mg/1 indicating an
effluent discharge 3 lbs. per day.
Nutrient loadings were relatively small. Values for ammonia nitrogen,
nitrate-nitrite as N, and total phosphorus were calculated as .2, .95,
and .1 lbs. per day.
DISCUSSION
The total suspended solids removal efficiency was considerably lower
than a value to be expected from tertiary filtration. Although the effluent
-------
American Hospital Supply Sewage Treatment Plant
March 11, 1971
Page 3
concentration was only 12 mg/1 the reduction efficiency should be
considerably higher. It is recommended that this low efficiency
value be further investigated.
In general the treatment plant is drastically underloaded. The
actual flow was .03 MGD compared to the design capacity of .1 MGD. This
created a low solids condition and undoubtedly reduced overall treatment
efficiency.
General plant appearance was good; the facility is new.

Operation Report on
Air Traffic Control Sewage Treatment Plant
7500 N.W. 58th Street
Medley, Dade County, Florida
March 15, 1971
INTRODUCTION
The Air Traffic Control Sewage Treatment Plant was inspected and
sampled on December 8, 1970 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained,, The treatment
plant consists of a Chicago Pump-rated Aeration package unit which
utilizes the extended aeration process and chlorination prior to dis-
charge to the 58th Street Canal. Initial contact was made through the
maintenance engineer, who supervises maintenance for the complex.
SUMMARY AND CONCLUSIONS
Removal efficiency for BOD^ equalled 99.5%, producing an effluent
concentration of 2.8 mg/1.
An influent settleable solids level of>40 ml/1 was reduced 100%.
A chlorine residual of 10 ppm was measured in the chlorine contact
tank.

March 15, 1971
Page 2
RESULTS
BOD^, COD and TOC estimated loadings equalled .21, 3 and .68 lbs.
per day based on the average design flow of .009 MGD. Respective
effluent concentrations were 2.8, 40 and 9 mg/1 indicating removal
efficiencies of 99.5, 96.5 and 97.4%.
Solids removal was equally effective. Settleable solids efficiency
was 100% and total suspended solids efficiency was 84.4%. The corre-
sponding suspended solids loading was 6 lbs. per day.
Nitrate-nitrite as N was present in a high concentration of 120 mg/1
in the final effluent. (It did not appear that detention time would
be long enough to generate a concentration of this magnitude. The
resulting effluent loading was 9 lbs. per day. The total phosphorus
effluent concentration equalled 2.8 mg/1.
DISCUSSION
The operation of the plant appeared adequate excepting the piping
for the return sludge line from the secondary clarifier. A conversation
with Mr. John D'acy, representative of Chicago Pump, indicated that the
faulty piping was to be replaced. The problem seemed to be caused by
the material of which the pipe was constructed, not being resistant to
corrosion.
The plant is operated by Mr. W. A. Coleman who is not certified.

Report on Waterborne Wastes from
Airport Lanes Sewage Treatment Plant
1850 N.W. 42nd Avenue
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The Airport Lanes Sewage Treatment Plant was inspected and
sampled on December 7, 1970 by Kenneth Schang. Grab samples of
the influent and effluent prior to chlorination were obtained. The
treatment plant incorporates two extended aeration package units each
with a capacity of .011 MGD. The effluent is chlorinated prior to
discharge to the Tamiami Canal. At the time of inspection only the
south plant was in operation. Initial contact was made through
Mr. James Barlow, plant operator.
SUMMARY AND CONCLUSIONS
The effluent concentration of BOD^ was measured at 6.76 mg/1
effecting a 97.27» removal efficiency and .62 lbs. per day loading. Total
suspended solids removal was 92.5% with 10 mg/1 present in the effluent
and .915 lbs. per day discharged based on the average design flow of
.011 MGD for the one plant in operation. Settleable solids were not
measurable in the effluent with 0.5 ml/1 being present in the influent.
A chlorine residual of 5 ppm existed in an effluent sample taken
from the dosing tank.

Report on Waterborne Wastes from
Barry College Sewage Treatment Plant
11300 N.E. 2nd Avenue
Miami Shores, Dade County, Florida
March 19, 1971
INTRODUCTION
The Barry College Sewage Treatment Plant was inspected and
sampled on December 3, 1970 by Kenneth Schang. Grab samples at
the influent and effluent were obtained. The treatment plant
consists of three Chicago Pump Extended Aeration package units
in parallel. Two have 15,000 GPD capacities and the remainder
a 30,000 GPD capacity. There is no chlorination prior to discharge
to a drainfield. The inspection was conducted in conjunction with
Mr. Louis Pinero, plant operator.
SUMMARY AND CONCLUSIONS
There is no chlorination prior to discharge. BOD removal was
85.87o producing an effluent concentration of 29 mg/1 with a loading
of 7.25 lbs. per day calculated using the average daily flow of .03 MGD.
Total suspended solids concentration in the effluent was measured as
46 mg/1 which indicates a removal efficiency of 877o and a loading of
11.51 lbs. per day. The 5 ml/1 of settleable solids present in the
influent were reduced to 0.3 ml/1 which is a removal efficiency of
94%.

RESULTS
BOD, COD and TOC removal efficiencies were 85.8, 89.6 and
67.7% respectively with the effluent concentrations equalling
29, 66 and 21 mg/1 respectively and loadings calculated as 7.25,
16.52 and 5.25 lbs. per day based on the average daily flow of
0.03 MGD. Total suspended solids measured at 46 mg/1 in the effluent
with removal efficiency being 87% and 11.51 lbs. per day being
discharged. The influent settleable solids of 5 ml/1 was reduced to
0.3 ml/1 which is an efficiency of 947».
Ammonia nitrogen, nitrate-nitrite nitrogen and total phosphorus
concentrations equalled 3.4, 11.4 and 9.3 mg/1 respectively with
0.85, 2.85 and 2.32 lbs. per day being discharged respectively.
DISCUSSION
Maintenance and operation of the treatment system appeared adequate
although none of the personnel are licensed. The recommendations are
that chlorination be incorporated and that the operator obtain a
license.

Biltmore Hotel Sewage Treatment Plant
1200 Anastasia Avenue
Coral Gables, Dade County, Florida
March 11, 1971
INTRODUCTION
The Biltmore Hotel Sewage Treatment Plant was inspected and
sampled on January 12, 1971, by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a .3 MGD capacity trickling filter system with chlorination
prior to discharge into the Coral Gables Canal.
SUMMARY AND CONCLUSIONS
The underloaded condition of this treatment plant eliminates
it as a pollutional hazard.
BOD influent concentration equals 10 mg/1 with 1.2 mg/1 being
measured in the effluent.
Settleable solids influent level was .1 ml/l. The treatment plant
reduced the value to zero ml/1.
The chlorine residual was .1 ppm, measured at the point of canal
discharge.

2. Primary settling.
3. Trickling filter.

Page 2
4. Secondary settling.
5. Chlorine contact.
6. Anaerobic sludge digester with sludge drying beds.
RESULTS
The most significant evaluation can be established by comparing
the influent and effluent chemcial parameters. Actual flow was not
measurable although it is known to be extremely low; based on the
fact that the .3 MGD capacity treatment plant is now taking care of
the wastes from the Biltmore Golf Course facilities only. For this
reason, loading figures are not valid.
The BOD5 and COD influent concentrations of 10 and 575 mg/1
were reduced to 1.2 and 17 mg/1 respectively. The TOC influent value
was 11 mg/1 and no reduction of this level was effected.
Settleable solids influent value was .1 ml/1 and the corresponding
effluent value was 0 ml/1. Influent total suspended solids were measured
at 26 mg/1 and a removal efficiency of 61.57o produced an effluent con-
centration of 10 mg/1.
Nutrient levels were insignificant: Kjeldahl nitrogen: .6 mg/1,
nitrate-nitrite as N: .05 mg/1 and total phosphorus: .2 mg/1.
DISCUSSION
No recommendation is necessary with regard to plant operation.
None of the maintenance personnel are licensed.
The general appearance of the plant was good.

Operation Report on
Blue Lakes Trailer Park Sewage Treatment Plant
S.W. 102 Avenue and W. Flagler Street
Miami, Dade County, Florida
January 25, 1971
INTRODUCTION
The Blue Lakes Trailer Park Sewage Treatment Plant was inspected
and sampled on December 17, 1970, by Kenneth Schang and Gary Cohen
(Dade County Pollution Control Inspector). Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a Marolf Extended Aeration package unit with chlorination
prior to effluent discharge into the Tamiami Canal. The inspection
was conducted in conjunction with an assistant to Mr. Bruce Rapee,
who maintains the system.
SUMMARY AND CONCLUSIONS
Treatment efficiency with respect to BOD^ was 98%, with an effluent
concentration of 4.2 ppm and an estimated stream loading of 1.19 lbs.
per day, based on an average design flow of .034 MGD.
Settleable solids provide a more significant pollutional factor
in that removal efficiency was only 50% with .7 ml/1 settleable
solids in the effluent.
-------
Blue Lakes Trailer Park Sewage
Treatment Plant
January 25, 1971
Page 2
It is recommended that the chlorine contact chamber be cleaned.
This cleaning should be done so as not to release the accumulated
solids to the Tamiami Canal.
INVENTORY
1. Basket screen, at the influent pipe to the wet well.
2. Aeration tanks, diffused air.
3. Secondary sedimentation.
4. Chlorine contact.
5. Aerobic sludge digester.
RESULTS
Treatment efficiency for BOD,, and COD was 90%, + with stream
loadings being estimated at 1.19 and 15.31 lbs. per day respectively,
based on the average design flow.
TOC removal efficiency was 81% with 20 ppm effluent concentration
and an estimated 5.67 lbs. per day loading.
Suspended solids removal was 87.l7o with only the settleable solids
test parameter dropping below standard efficiency requirements at 50%;
this is compensated by the low discharge concentration of .7 ml/1.
Nitrogen loadings were: organic-N, .74 lbs. per day, nitrate-nitrite
as N, .45 lbs. per day, and the total phosphorus load was 4.05 lbs.
per day, all based on design flow.
-------
Blue Lakes Trailer Park Sewage
Treatment Plant
January 25, 1971
Page 3
The chlorine residual approached 2 ppm with an adequate
apparent contact time based on Dade County standards. An effective
kill of organisms should be obtained.
DISCUSSION
The treatment plant appeared to be adequately maintained with
the exception of the chlorine contact chamber.
An accumulation of solids in the chlorine contact chamber result
in the carry-over of solids into the final effluent. These solids
should be removed in such a manner that they will not escape into the
Tamiami Canal, and operations should be modified to prevent their
future accumulation.
Mechanical equipment was in good working order and performing
properly.
Mr. Bruce Rapee, although not licensed at the time of inspection,
had recently completed the class "C" operating examination and was
awaiting the results.

Report on Waterborne Wastes from
Camp Matecumbe Sewage Treatment Plant
S.W. 120th Street & 137th Avenue
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The Camp Matecumbe Sewage Treatment Plant was inspected and
sampled on December 9, 1970 by Kenneth Schang and Joe Hopson
(Dade County Pollution Control Inspector). Grab samples of the
influent and effluent were obtained. The treatment plant is a
Defiance Extended Aeration package unit with the effluent discharged
to open sand filters. The inspection was conducted in conjunction
with Mr. Raul Pugar, who maintains the system.
SUMMARY AND CONCLUSIONS
Treatment efficiency exceeded 907o for all parameters evaluated
except settleable solids where 807o removal was attained. However, the
effluent concentration was only .1 ml/1.
The BOD effluent concentration was 7.2 mg/1.
The effluent is not chlorinated prior to discharge to the open
sand filters.
INVENTORY
1. Comm imtor .
-------
Camp Matecumbe Sewage Treatment Plant

Page 2
2. Aeration tanks; diffused air.
3. Secondary sedimentation.
4. Dosing tank.
5. Open sand filters.
6". Sludge holding tank, with sludge hauled away when required.
RESULTS
The BOD^, COD and TOC effluent concentrations were 7.2, 24 and 9 mg/1
respectively.
An 807o removal efficiency for settleable solids produced approximately
.1 ml/1 in the effluent.
Nitrogen concentrations were all insignificant except nitrate-nitrite
as N, which was measured at 13.8 mg/1. This high level indicates low
flow into the plant and a resulting longer detention which increases
nitrification.
Total nitrogen and phosphorus effluent concentrations were 1.1 and
3.8 mg/1 respectively.
DISCUSSION
A valid discussion of plant operation and efficiency is difficult
considering the extremely low flow entering the treatment plant within several
weeks prior to sampling. Conversation with the operator produced an estimate
that the system may be operating as much as three-quarters below the design
flow. Visually, the aeration tank solids appeared to have good color and were
of adequate concentration to effect good treatment efficiency. A more critical
evaluation should be prepared when the facility is nearer design population.

Operation Report on
Casa Granada Apartments Sewage Treatment Plant
S.W. 87th Avenue & 141st Street
Miami, Dade County, Florida
January 25, 1971
INTRODUCTION
The Casa Granada Sewage Treatment Plant was inspected and
sampled on December 10, 1970, by Kenneth Schang. Grab samples of
the influent and effluent after chlorination were obtained. The
treatment plant is a contact stabilization package unit with Jetflo
tertiary filters and discharge to the C-100 canal. Initial contact
was made through James Barlow, plant operator.
SUMMARY AND CONCLUSIONS
A treatment efficiency of 96.4% with respect to BOD^ removal
produced an effluent concentration of 6.4 mg/1.
No settleable solids were measured in the effluent and removal of
suspended solids was 97.1%.
The chlorine residual of 3 mg/1 should effect a successful
bacteriological kill.
Flow measuring device should be installed.

were reduced 1007» from an influent concentration of 3 ml/1.
Chlorine residual was measured at 3 ppm in the dosing tank prior to
discharge to C-100 canal.
Since there was no flow meter on the plant, it is not possible
to compute actual loading rates. Approximate loadings based on design
flow of 0.02 MGD are shown in the attached calculation table.
DISCUSSION
The Casa Granada Sewage Treatment Plant at the time of inspection
was producing an excellent effluent with excellent removal efficiencies.

Report on Waterborne Wastes from
Coast Guard Station Sewage Treatment Plant
100 McArthur Causeway
Miami, Dade County, Florida
March 19, 1971
INTRODUCTION
The Coast Guard Station Sewage Treatment Plant was inspected
and sampled by Kenneth Schang on January 14, 1971. Grab samples
of the influent and effluent after chlorination were obtained. The
treatment plant utilizes the extended aeration process with
chlorination prior to discharge to Government Cut and is designed to
treat 10,000 GPD. The inspection was conducted in conjunction with
Mr. James Campbell, who operates the system.
SUMMARY AND CONCLUSIONS
Removal of BOD approached 98% with concentrations of 390 and
8 mg/1 respectively in the influent and effluent.
An influent settleable solids level of 2.5 ml/1 was reduced
to 0 ml/1 in the effluent.
A chlorine residual of 1 ppm was measured in the chlorine contact
chamber immediately prior to discharge.
INVENTORY
1. Comminutor.
2. Aeration tank, diffused air system.
3. Secondary sedimentation.
4. Chlorine contact tank.
5. Aerobic sludge holding tank, diffused air system.
-------
Coast Guard Station Sewage Treatment Plant
March 19, 1971
Page 2
RESULTS
BOD, COD and TOC effluent loadings were 0.96, 10.57 and 2.88
lbs. per day calculated from the 14,400 GPD flow registered by a flow
meter during the inspection.
Total suspended solids removal was inadequate with an effluent
concentration of 112 mg/1 indicated a removal efficiency of 28.2%
and a loading of 13.45 lbs. per day. Settleable solids were reduced
to 0 ml/1 in the effluent.
Loadings for ammonia nitrogen, nitrate-nitrite as N, and total
phosphorus were 0.22, 1.18 and 1.45 lbs. per day respectively based
on effluent concentrations of 1.8, 9.8 and 12.1 mg/1 respectively.
Organic nitrogen was discharged at 1.7 mg/1 for a load of 0.2 lbs.
per day.
DISCUSSION
Two recommendations followed the visual inspection:
1. The quantity of dissolved oxygen present in the aeration tank
and aerobic digester should be measured; the color of the solids in
both tanks were extremely dark indicating these treatment processes may
need more air.
2. This plant is overloaded. An additional large tank is being
constructed to be used as an aerobic sludge holding tank so that the
plant can be converted from extended aeration to contact stabilization.

Operation Report on
Country Club Garden Apartments Sewage Treatment Plant
N.W. 79th Avenue and 41st Street
Medley, Dade County, Florida
March 16, 1971
INTRODUCTION
The Country Cl.ub Garden Apartments Sewage Treatment Plant was
inspected and sampled on January 15, 1971 by Kenneth Schang. Grab
samples of the influent and effluent after chlorination were obtained.
The treatment plant consists of two .07 MGD capacity Davco Contact
Stabilization package units in parallel with tertiary filtration and
chlorination prior to discharge to a private lake. Only one plant
was in operation at the time of inspection due to low loading conditions.
Initial contact was made through Mr. Pullam of Environmental Consultants,
plant operator.
SUMMARY AND CONCLUSIONS
An influent BOD^ cf 251 mg/1 was reduced to 3.8 mg/1 for a removal
efficiency of 98.5%.
Settleable solids were reduced 100% from the influent level of
2.5 mg/1. Total suspended solids removal efficiency was 86.4%.
The chlorine residual measured in the final effluent equalled
2 ppm.

5. Stabilization; diffused air system.
6. Equalizing tank plus chlorination.
7. Tertiary filters.
8. Aerobic digester; diffused air system.
RESULTS
Removal efficiencies for BOD^, COD and TOC were calculated as
98.5, 94.6 and 91.9%, producing effluent discharges of .63, 5.84
and 2.17 lbs. per day based on the actual flow at the time of
inspection of .02 MGD.
Total suspended solids removal was 86.4% with 27 mg/1 in the
effluent and a 4.5 lbs. per day loading. Settleable solids were
reduced from 2.5 ml/1 to zero ml/1 in the effluent.
Organic nitrogen, nitrate-nitrite nitrogen and total phosphorus
loadings were .27, 1.3 and .92 lbs. per day. The high nitrate-nitrite
as N value is most probably due to the high detention time induced by
the low flow conditions.
DISCUSSION'
The overall plant operation appeared to be above adequate with
excellent removal efficiencies. One minor consideration is the
-------

effluent suspended solids concentration of 27 mg/1. With tertiary
filtration this value should be somewhat lower. An evaluation of
filter efficiency is recommended.

Report on Waterborne Wastes from
Dade Christian Schools Sewage Treatment Plant
6601 N.W. 167th Street
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The Dade Christian Schools Sewage Treatment Plant was inspected
and sampled on December 1, 1970 by Kenneth Schang and Frank Ansley
(Dade County Pollution Control Inspector). Grab samples of the influent
and effluent after chlorination were obtained. The treatment plant is
a Pollution Control Extended Aeration package treatment unit with a
Graver filter and chlorination prior to discharge to the 205th Street
Canal. The inspection was conducted in conjunction with Mr. Bill Matthews,
who operates the system.
SUMMARY AND CONCLUSIONS
Although removal of settleable solids was evaluated as 100%, the
efficiency of treatment with respect to BOD^ was only 69.1%. This produced
an effluent concentration of 42 mg/1 with 5.25 lbs. per day being dis-
charged, based on the average daily flow of 15,000 gallons. This is a
new plant and a low rate solids buildup in the aeration tank has
dreastically reduced the treatment efficiency.
The chlorine residual was measured at .5 ppm.

2. Aeration tank, diffused air system.
3. Secondary sedimentation.
4. Graver filter.
5. Chlorination.
6. Aerobic digester, diffused air.
RESULTS
Removal of BOD^, COD and TOC was 69.1, 79.1 and 75.5% respectively
leaving effluent concentrations of 42, 120,and 27 mg/1 with 5.25, 15.01
and 3.38 lbs. per day being discharged based on the average daily flow
of 15,000 gallons.
Total suspended solids were measured at 13 mg/1 signifying a
1.63 lb. per day discharge in the effluent. The influent level for
settleable solids (.3 ml/1) was totally removed.
Nutrient loadings were significant in that 136 mg/1 of nitrate-
nitrite nitrogen was present in the effluent sample. This is a 17.01
lbs. per day discharge and indicates the extremely long detention time
inherent to this plant due to low flow. Ammonia nitrogen discharge was
somewhat less at 1.00 lbs. per day, while total phosphorus discharged
equalled 6.5 mg/1 and .81 lbs. per day.
DISCUSSION
The basic problem with this treatment plant is the severe underloaded
condition. The design flow of 70,000 gallons per day is substantially
-------
Dade Christian Schools Sewage Treatment Plant
February 23, 1971
Page 3
higher than the actual average daily flow of 15,000 gallons per day.
As a result the aeration tank has an extremely low solids content as
adequate treatment efficiency cannot be attained. If this condition
does not rapidly improve it is recommended that an active mixed liquor
be trucked in to increase the aeration tank solids level.
Mr. Bill Matthews operates the treatment plant with no level of
certification; Mr. Jack Whitney, a licensed operator, has been
retained as a consultant.

INTRODUCTION
The Del-Ray Gardens Sewage Treatment Plant was inspected and
sampled on January 5, 1971 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a Davco Contact Stabilization package unit with chlorination
prior to discharge to the Little River Canal. Initial contact was made
through Mr. Hollis Wheeler, plant operator.
SUMMARY AND CONCLUSIONS
BOD^ removal efficiency equalled 94.4%.
Total suspended solids removal equalled 88.7% with an effluent
concentration of 14 mg/1.
A chlorine residual of 10+ ppm was measured in the chlorine
contact tank immediately prior to discharge.
INVENTORY

Del-Ray Gardens Sewage Treatment Plant
March 15, 1971
Page 2
DISCUSSION
BOD5j COD and TOC removal efficiencies were 94.4, 96.1, and
97.3% respectively with corresponding effluent concentrations of
12.5, 31 and 5 mg/1 respectively.
The plant effected 100% reduction of settleable solids from an
influent level of .2 ml/1. Total suspended solids were reduced 88.7%
to 14 mg/1 in the effluent.
Nutrient effluent concentrations were relatively insignificant.
Organic nitrogen: 1.08 mg/1; nitrate-nitrite as N: .6 mg/1; total
phosphorus: 7.2 mg/1.
RECOMMENDATIONS
The treatment plant has been phased out, with the raw sewage now
going to ocean outfall.
At the time of inspection, the treatment plant was in good physical
condition, with comparable operating efficiencies.
Mr. Wheeler is licensed class "C".

Report on Waterborne Wastes from
El Rancho Apartments Sewage Treatment Plant
14500 S.W. 88th Avenue
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The El Rancho Apartment Sewage Treatment Plant was inspected
and sampled on December 10, 1970 by Kenneth Schang. Grab samples
of the influent and effluent after chlorination were obtained.
The unit is a contact stabilization package plant with Jetflo tertiary
filters and discharge to a soakage pit. The inspection was conducted
in conjunction with James Barlow, plant operator.
SUMMARY AND CONCLUSIONS
BOD^ removal efficiency equalled 96.5% with a stream loading of
1.43 lbs. per day and an effluent concentration of 8.6 ppm.
Total suspended solids removal efficiency approached 95% with
2.17 lbs. per day loading being discharged. Settleable solids were
removed 100% based on an influent concentration of 6 ml/1.
A chlorine residual of 1.5 ppm existed in the final dosing tank
prior to discharge to the soakage pit.

5. Jetflo filters and chlorination.
6. Dosing tank.
7. Reaeration tank, contact stabilization.
8. Aerobic digester, waste sludge hauled away.
RESULTS
A considerable quantity of nitrate-nitrite nitrogen in the effluent
was the only parameter of major concern. The concentration was 16.4 mg/1
with a stream loading of 2.74 lbs. per day based on the average design
flow of .02 MGD. In examining the other nutrient loadings, organic
nitrogen equalled .25 lbs. per day with an effluent concentration of
1.5 ppm and a total phosphorus loading of .6 lbs. per day based on a
concentration of 3.6 mg/1.
Rated removal efficiency was, in all cases, in excess of 90%
excepting the removal of TOC which approached 89%. BOD^, COD and TOC
effluent concentrations were 8.6, 28 and 30.5 mg/1 with the loading
discharged being 1.43, 4.67 and 5.09 lbs. per day.
Settleable solids were 100% removed and total suspended solids
were measured at 13 mg/1 which means 2.17 lbs. per day of total
suspended solids being discharged.

Operation Report on
Florida Portland Cement Sewage Treatment Plant
Krome Avenue and S.W. 64th Street
Westwood Lakes, Dade County, Florida
March 15, 1971
INTRODUCTION
The Florida Portland Cement Sewage Treatment Plant was inspected
and sampled on January 8, 1971 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant consists of an Imhoff tank with trickling filter and chlorination
prior to discharge to a drainfield. Initial contact was made through
the maintenance engineer for the entire complex.
SUMMARY AND CONCLUSIONS
BOD removal was 89.67o effective with 8 mg/1 being measured in the
effluent.
An influent settleable solids level of .8 ml/1 was reduced to zero
in the effluent.
The final chlorine residual equalled 3 ppm.
INVENTORY
1. Imhoff tank; waste sludge hauled away.
2. Trickling filter.
3. Chlorine contact.
RESULTS
(Since there was no flow at the time of inspection, loadings
could not be accurately determined).
-------
Florida Portland Cement Sewage Treatment Plant
March 15, 1971
Page 2
BOD5, COD and TOC removal efficiencies were 89.6, 81.3 and
76.67» with effluent concentrations of 8, 95 and 41 mg/1.
Total suspended solids were removed with 96.9% efficiency pro-
ducing an effluent concentration of 14 mg/1. Settleable solids removal
was 100% effective.
Organic nitrogen, nitrate-nitrite as N, and total phosphorus
effluent concentrations were measured at 2.02, 9.4 and 5.8 mg/1
respectively.
DISCUSSION
Considering efficiency data in conjunction with the visual
inspection, no recommendations appear to be necessary.
Plant operation is the duty of maintenance personnel. None are
certified as operators.
Overall plant condition was good.

Report on Waterborne Wastes from
Food Fair Store #291 Sewage Treatment Plant
10400 N.W. 7th Avenue
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The Food Fair Store #291 Sewage Treatment Plant was inspected and
sampled on December 3, 1970 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a Chicago Pump Extended Aeration package unit with chlorination
prior to discharge to a drainfield. The inspection was conducted in
conjunction with Mr. J. D'Agostino, plant operator.
SUMMARY AND CONCLUSIONS
Removal efficiency was above 90% for all test parameters. BOD^
effluent concentration was 3 mg/1 indicating a .38 lb. per day discharge
calculated using the design flow of .015 MGD.
Removal of suspended solids equalled 957» with an effluent concentra-
tion of 46 mg/1 and 5.75 lbs. per day being discharged. There were no
settleable solids in the influent or effluent.
The chlorine residual in the dosing tank was measured as 2 ppm.

1. Bar screen and comminutor at influent to the wet well.
2. Aeration tank, diffused air.
3. Secondary sedimentation.
4. Dosing tank and chlorination.
5. Anaerobic sludge holding tank.
RESULTS
Removal efficiency for BOD^, COD and TOC was 98.9, 90.1 and
90.3% respectively. This is equivalent to effluent concentrations of
3, 60, and 15 mg/1 with the corresponding loading being .38, 7.5, and
1.88 lbs. per day based on the average design flow.
There were no settleable solids present in either the influent
or effluent, while suspended solids removal efficiency approached
95%. This resulted in an effluent concentration of 46 mg/1 and 5.75
lbs. per day being discharged to the drainfield.
Nutrient loadings for organic nitrogen, nitrate-nitrite nitrogen
and total phosphorus were .24, 1.88 and .7 lbs. per day calculated
from 1.9, 15 and 5.6 mg/1 effluent concentrations.
DISCUSSION
The one problem with regard to this treatment plant was the
existence of pop-ups in the secondary clarifier. As a solution it
is suggested that the rate of sludge return be evaluated to

Report on Waterborne Wastes from
Goldberg Apartments Sewage Treatment Plant
6775 S.W. 44th Street
South Miami, Dade County, Florida
March 15, 1971
INTRODUCTION
The Goldberg Apartments Sewage Treatment Plant was inspected and
sampled on January 11, 1971 by Kenneth Schang. Grab samples at the
influent and effluent after chlorination were obtained. The treatment
plant is a Defiance Extended Aeration package unit, with tertiary fil-
tration and chlorination prior to discharge to a soakage pit. Initial
contact was made through Mr. Goldberg, owner of the apartment building.
SUMMARY AND CONCLUSIONS
BOD^ removal efficiency equalled 96% producing an effluent con-
centration of 8.5 mg/1.
Total suspended solids were reduced 79.6% from 108 mg/1 to 22 mg/1.
A chlorine residual of .25 ppm was measured in the effluent immedi-
ately prior to discharge.
INVENTORY
1. Bar screen.
2. Aeration tanks; diffused air system.
3. Secondary sedimentation.
4. Chlorination.
5. Tertiary filtration.
6. Aerated holding tank; diffused air system.
-------
Goldberg Apartments Sewage Treatment Plant
March 15, 1971
Page 2
DISCUSSION
BOD^, COD and TOC removal efficiencies equalled 96, 85.5 and
85.27° respectively with corresponding effluent concentrations of
8.5, 91 and 20 mg/1 and respective stream loadings of .71, 7.59 and
1.67 lbs. per day based on the design flow.
A zero settleable solids value was measured in the influent and
effluent. Total suspended solids removal efficiency was 79.67», producing
an effluent concentration of 22 mg/1 and a stream loading of 1.83 lbs.
per day.
Nutrient effluent concentrations were relatively significant:
ammonia nitrogen: 16.8 mg/1; nitrate-nitrite as N: 19.2 mg/1; total
phosphorus: 11.9 mg/1.
RECOMMENDATIONS
An adequate evaluation of this treatment plant is difficult because
of relative newness. Aeration tank solids are not to proper levels.
The plant was in good physical condition.
Mr. Dudley, plant operator, is preparing to take the licensing
examination for class "C" certification.

Operation Report on
Helman Court Apartments Sewage Treatment Plant
15401 Biscayne Drive
Homestead, Dade County, Florida
March 15, 1971
INTRODUCTION
The Helman Court Apartments Sewage Treatment Plant was inspected
and sampled on December 9, 1970 by Kenneth Schang and Joe Hopson
(Dade County Pollution Control Inspector). Grab samples of the influent
and effluent were obtained. The treatment plant utilizes the extended
aeration process with chlorination prior to discharge to a drainfield.
Initial contact was made through Mr. Helman, owner of the apartment
complex.
SUMMARY AND CONCLUSIONS
The BOD^ removal efficiency approached 977» with an effluent con-
centration of 23.9 mg/1.
An effluent settleable solids level of .1 ml/1 was a 97.5% reduction
from the 4 ml/1 present in the influent.
There was a total absence of chlorine in the effluent; the chlorinator
did not appear to be operating properly.
INVENTORY
1. Aeration tanks; diffused air system.
2. Secondary sedimentation.
3. Dosing tank + chlorination.
4. Anaerobic sludge holding tank, with waste sludge being recirculated.
-------
Helman Court Apartments Sewzge Treatment Plant
March 15, 1971
Page 2
RESULTS
BOD^, COD and TOC removal efficiencies of 96.7, 94.5 and 94.6%
respectively produced estimated effluent loadings of 4.98, 17.9 and
3.96 lbs. per day respectively, based on the design flow of .025 MGD.
Settleable solids removal was equally efficient at 97.5% with
.1 ml/1 presfint in the effluent. Total suspended solids effluent con-
centration was measured at 166 mg/1 for an efficiency of 66.57» and
an estimated loading of 34.6 lbs. per day.
Organic nitrogen, nitrate-nitrate as N, and total phosphorus
effluent concentrations were 7.9, 4.0 and 7.7 mg/1 respectively.
DISCUSSION
The physical appearance of the plant did not appear adequate in
that several sections of piping were loose, the chlorinator was not
functioning, and the dosing tank was dirty. Alleviation of these con-
ditions is recommended.
In addition, recirculation of the anaerobic sludge from the
holding tank illustrates poor practice; this could induce a serious
loading condition on the treatment plant that may upset operation.
Another more adequate method of disposal should be incorporated.
A flow meter should be installed.
Operation of the plant is conducted by Mr. Eric Etienne, apartment
manager. Mr. Etienne is not certified as an operator.

INTRODUCTION
The Hialeah City Hall Sewage Treatment Plant was inspected and
sampled on December 1, 1970 at approximately 10:30 a.m., by
Kenneth Schang and Frank Ansley (Dade County Pollution Control
Inspector). Grab samples of the influent and effluent after pre-
chlorination were obtained. The plant is a Chicago Pump-Rapid Block
Aeration package unit with effluent being discharged into a drainfield.
The inspection was conducted in conjunction with Mr. George Wheeler,
sewage treatment operator for the City of Hialeah. Initial contact
was made through Mr. Beverage of the City of Hialeah, Department of
Water and Sewers.
SUMMARY AND CONCLUSIONS
BOD^ removal equalled 90.4% with an effluent concentration of
26 ppm and an estimated loading of 8.67 lbs. per day calculated from
the average design flow of .04 MGD.
An influent settleable solids level of 15 ml/1 was reduced to

7. Aerobic digestion, diffused air with sludge being trucked
away.
Design flow is .04 and the plant serves approximately 550
people.
RESULTS
Estimated loadings for BOD^, COD and TOC were 8.67, 44.7 and
14.68 lbs. per day respectively based on the average design flow of
.04 MGD and effluent concentrations of 26, 134, and 44 mg/1. This
signifies respective removal efficiencies of 90.4, 83.2 and 64.8%.
The removal of total suspended solids equalled 82.4% with an
effluent concentration of 52 mg/1 and a 99.3% settleable solids removal
produced .1 ml/1 in the effluent.
Estimated nutrient loadings were as follows: Ammonia nitrogen:
4-00 lbs. per day and 12.0 mg/1 effluent concentration, nitrate-nitrite
as N: 1.33 lbs. per day and 4 mg/1 effluent concentration, total
phosphorus: 2.37 lbs. per day and 7.1 mg/1 effluent concentration.

The Hialeah Convalescent Home Sewage Treatment Plant was
inspected and sampled on December 1, 1970 at approximately 11:15 a.m.,
by Kenneth Schang and Frank Ansley (Dade County Pollution Control
Inspector). Grab samples of the influent and effluent after chlorina-
tion were obtained. The plant is a package W & S A-20 Contact
Stabilization unit with effluent bein^ discharged into two drainfields.
The inspection was conducted in conjunction with Mr. George H. Wheeler,
sewage treatment plant operator for the City of Hialeah. Initial
contact was made through Mr. Beverage of the City of Hialeah, Depart-
ment of Water and Sewers.
SUMMARY AND CONCLUSIONS
The treatment plant effected a 69.1% removal of BOD with an
effluent concentration of 94 mg/1. The corresponding loading estimated
was 19.6 lbs. per day based on the average design flow of 0.025 MGD.
Settleable solids measured at 1 ml/1 in the influent were increased
five times to 5 ml/1 in the effluent.
The chlorine residual was 1.5 ppm in the effluent.

INVENTORY
The unit is a contact stabilization package plant utilizing:
1. Bar rack.
2. Aeration tanks, diffused air system.
3. Secondary sedimentation, with continuous air lifted
return sludge.
4. Reaeration, diffused air system.
5. Chlorine contact, with effluent to two drainfields.
6. Aerobic digester, with sLudge being trucked away.
Design flow is 0.025 MGD and the plant serves approximately 350
people.
RESULTS
Removal of BOD, COD and TOC equalled 69.1, 64.6 and 26.1% respective-
ly, leaving effluent concentrations of 94, 264 and 85 mg/1. Loadings
calculated from the average design flow of 0.025 MGD were 19.6, 55.04
and 17.72 lbs. per day respectively.
Solids removal was relatively inefficient. The influent settleable
solids of 1 ml/1 was increased 500% to 5 ml/1 in the effluent. Efficiency
for total suspended solids was 40.3% producing an effluent concentration
of 142 mg/1 and a loading of 29.6 lbs. per day.
Ammonia nitrogen, nitrate-nitrite as N, and total phosphorus con-
centrations and loadings were 19.0 mg/1, 3.96 lbs. per day; 0.5 mg/1,
0.1 lbs. per day; 6.1 mg/1, 1.27 lbs. per day respectively.

DISCUSSION
General plant condition: fair. This is due to:
1. The unit having been secondhand when purchased and installed
in 1969.
2. Maintenance being provided by the Hialeah Convalescent Home.
Maintenance is not always adequate.
3. The nature of the population served. Items introduced by
the elderly people into the waste system have induced mechanical
breakdowns (according to the plant operator).
Mr. Wheeler is a class "C" operator.
The recommendation that follows is to upgrade the existing facility
by the necessary expenditure of funds with regard to new equipment and
proper maintenance. This should include installation of a flow meter.

Report on Waterborne Wastes from
Hialeah Hospital Sewage Treatment Plant
651 E. 25th Street
Hialeah, Dade County, Florida
March 22, 1971
INTRODUCTION
The Hialeah Hospital Sewage Treatment Plant was inspected and
sampled on December 1, 1970 by Kenneth Schang and Frank Ansley
(Dade County Pollution Control Inspector). Grab samples of the
influent and effluent after chlorination were obtained. The
treatment plant consists of one extended aeration package unit in
parallel with two Chicago Pump Contact Stabilization package plants
and an open sand filter plus chlorination prior to discharge to
a drainfield.
SUMMARY AND CONCLUSIONS
Chlorine residual is of primary concern with regards to hospital
wastes. A value of 2.5 ppm was measured in the dosing tank which should
effect a sufficient bacteriological kill provided that detention time
is adequate.
BOD removal efficiency was 92.2% with 17.26 lbs. per day being
discharged based on the design flow of 0.09 MGD.
Suspended solids were measured at 13 mg/1 signifying a 9.76 lbs.
per day discharge. Settleable solids in the influent (2.5 ml/1) were
reduced to zero for a 100% removal efficiency.

5. Aerobic digesters.
6. Open sand filters.
7. Dosing tank plus chlorination.
RESULTS
The treatment plant effected 92% removal of BOD indicating a
discharge of 17.26 lbs. per day based on the average design flow of
0.09 MGD. Removal of COD was less efficient in that 219.18 lbs. per
day or 292 mg/1 were discharged in the effluent after 54.8% was
removed. The TOC concentration was measured at 18 mg/1 with a loading
of 13.51 lbs. per day being the result.
Effluent settleable solids equalled zero, with the quantity present
in the influent being 2.5 mg/1. Efficiency of suspended solids removal
was 91.2% based on an effluent concentration of 13 mg/1 and a discharge
of 9.76 lbs. per day.
The quantities of ammonia nitrogen, nitrate-nitrite nitrogen and
total phosphorus were 9.0, 10.5 and 7.0 mg/1 respectively with the
consequent loadings equalling 6.76, 7.88 and 5.25 lbs. per day.

Operation Report on
Holiday Inn Sewage Treatment Plant
1111 S. Royal Poinciana Boulevard
Miami, Dade County, Florida
January 25, 1971
INTRODUCTION
The Holiday Inn Sewage Treatment Plant was inspected and
sampled on December 7, 1970, by Kenneth Schang. Grab samples of
the influent and effluent before chlorination were obtained. The
treatment plant utilizes the extended aeration process and chlorination
prior to discharge to the Miami Canal.
SUMMARY AND CONCLUSIONS
The system effected 907., + removal of BOD, COD and settleable solids.
BOD concentration was 1.96 mg/1 with an estimated .41 lb./day loading
being placed on the receiving waterway based on the design flow of
.025 MGD.
A 97.1% removal efficiency of settleable solids produced an effluent
concentration of .1 ml/1.
Based on Dade County standards the treatment plant must be considered
operating adequately.
Flow meter should be installed.

INVENTORY
1. Temporary surge tank, consisting of a septic tank truck.
2. Comminutor.
3. Aeration tanks, diffused air system.
4. Secondary sedimentation.
5. Chlorine contact, essentially utilizes a dosing tank.
6. Aerobic sludge digester.
RESULTS
BOD, COD and TOC effluent concentrations were 1.96, 46 and 16 mg/1
respectively.
Treatment efficiency with respect to settleable solids removal was
97.1% with .1 ml/1 being discharged to the Miami Canal.
The concentration of ammonia-N can be considered more significant
in that 16.8 mg/1 or an estimated 3.50 lbs./day as elemental nitrogen
was present in the effluent sample. Remaining nutrients were considerably
less prevelant; nitrate-nitrite as N concentration was 1.8 mg/1 with
a stream loading equivalent to .38 lbs./day based on design flow. Total
phosphorous was present at 8.8 mg/1 with an estimated loading of 1.83
lbs./day.
DISCUSSION
Through conversation with the plant operator, it was determined that
a hydraulic problem inherent to the hotel being served by the treatment
plant was the basis of past efficiency breakdowns. An early morning
-------
Holiday Inn Sewage Treatment Plant
January 25, 1971
Page 3
surge prior to check-out time equal to several times the average
design flow upset the treatment system and washed solids out of the
plant. This was temporarily remedied by installation of a septic
tank truck to act as a holding tank and a splitter box. Since
installation, the effluent has been of consistent good quality and
plans have been submitted to Dade County Pollution Control for a
permanent concrete,holding tank.
The appearance of the plant and condition of the mechanical
equipment was good. Proper operation has resulted in a considerable
improvement of plant efficiency.
The plant operator is James Barlow, who has a "C" classification.
In addition, verbal conversation with the operator yielded
information that the present extended aeration treatment plant would
be converted to contact stabilization in the near future.

Operation Report on
Howard Johnson's Motel Sewage Treatment Plant
1980 N.W. Le Jeune Road
Miami, Dade County, Florida
March 15, 1971
INTRODUCTION
The Howard Johnson's Motel Sewage Treatment Plant was inspected
and sampled on December 11, 1971 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a Davco Contact Stabilization package unit with chlorination
prior to discharge to the Tamiami Canal. Initial contact was made
through Mr. Asay, motel manager.
SUMMARY AND CONCLUSIONS
BOD^ removal efficiency equalled 97.9% producing an effluent con-
centration of 7.8 mg/1.
Total suspended solids were reduced 97.4% to 13 mg/1.
The chlorinating device was not operational at the time of
inspection; a corresponding chlorine residual of 0 ppm was measured
in the effluent at the point of discharge.
INVENTORY

Page 2
March 15, 1971
3. Stabilization tank; diffused air system.
4. Chlorine contact.
5. Aerobic digester; diffused air system.
RESULTS
BOD^, COD and TOC removal efficiencies equalled 97.9, 95.9 and 86.7%
respectively with corresponding effluent concentrations of 7.8, 66 and
27 mg/1. The stream loadings were calculated as 1.63, 13.76 and 5.63
lbs. per day based on the design flow of .025 MGD.
The influent settleable solids value of 16 mg/1 was reduced 99.4%
to .1 ml/1. Total suspended solids removal efficiency was 97.4% with
an effluent concentration of 13 mg/1 and a stream loading of 2.71
lbs. per day.
Nutrient concentrations and loadings were as follows: ammonia
nitrogen: 9.6 mg/1 and 2.0 lbs. per day; nitrate-nitrite as N: 3.2 mg/1
and .67 lbs. per day; total phosphorus: 1.7 mg/1 and .35 lbs. per day.
DISCUSSION
The physical appearance of the treatment plant was poor, and the
facility was in need of additional maintenance. One blower sounded to
be near breakdown.
The chemical data is also deceiving. For the removal efficiencies
to be as high as they are, the chlorine contact chamber would have to be
-------

utilized as a tertiary settling tank. A considerable quantity of floe
was flowing over the weir from the secondary settling tank. In
addition, a significant quantity of pop-ups were present in the
secondary settling tank, and the operation of the mechanical sludge
scraper was questionable. Further evaluation of the problems existing
with this treatment plant is recommended.

Jade Gardens Apartments Sewage Treatment Plant
S.W. 65th Avenue and U.S. 1
South Miami, Dade County, Florida
March 15, 1971
INTRODUCTION
The Jade Gardens Apartments Sewage Treatment Plant was inspected
and sampled on January 11, 1971, by Kenneth Schang. Grab samples of
the influent and effluent after chlorination were obtained. The treat-
ment plant is a Davco Contact Stabilization package unit with chlorina-
tion prior to discharge to Snapper Creek Canal. Initial contact was
made through the apartment manager.
SUMMARY AND CONCLUSIONS
Removal of BOD^ was equal to 99.1% with an effluent concentration
of 5 mg/1.
An influent suspended solids level of 4116 mg/1 was reduced 99.7%
to 14 mg/1.
At the time of inspection the chlorinating device was not operating
properly and no residual was measurable in the effluent.
INVENTORY

2. Secondary sedimentation.
3. Stabilization tank; diffused air system.
4. Chlorination.
5. Aerobic digester; diffused air system.

March 15, 1971
DISCUSSION
(The height of water over the V-notch weir was too minimal to be
effectively measured at the time of inspection). BOD^, COD and TOC
removal efficiencies were 99.1, 99.4 and 98% with corresponding effluent
concentrations of 5, 49 and 22 mg/1 respectively.
Total suspended solids were reduced 99.7% to 14 mg/1. An influent
settleable solids level of 18 ml/1 was reduced to .1 ml/1 for a removal
efficiency of 99.47<>.
Nutrient effluent concentrations were as follows: ammonia nitrogen:
14.8 mg/1; nitrate-nitrite as N: .1 mg/1; total phosphorus: 9 mg/1.
RECOMMENDATIONS
Although the plant effected excellent removal efficiencies, the
general physical condition was not good. More adequate maintenance
is recommended.
A licensed operator does not maintain the treatment plant.

5. Chlorination.
6. Aerobic sludge digester, diffused air system.
DISCUSSION
Removal efficiencies for BOD^, COD and TOC were 96.9, 94.6 and
b9.7 mg/1. This produced respective effluent concentrations of
6, 26 and 15 mg/1 with corresponding stream loadings of 2.5 10.8 and
6.3 lbs. per day based on the estimated flow of .05 MGD.
Settleable solids were reduced 100% from an influent level of

Kendall Complex Sewage Treatment Plant
8500 S.W. 107th Avenue
Kendall, Dade County, Florida
March 16, 1971
INTRODUCTION
The Kendall Complex Sewage Treatment Plant was inspected and
sampled on February 2, 1971, by Kenneth Schang. Grab samples of
the influent and effluent prior to chlorination were obtained. The
treatment plant utilizes an Irahoff tank, trickling filter, oxidation
pond and chlorination prior to discharge to a field. The inspection
was conducted in conjunction with a member of the Dade County maintenance
staff.
SUMMARY AND CONCLUSIONS
BOD^ removal equalled 857o with an effluent concentration of 47 mg/1.
There was an increase in the total suspended solids influent
value of 8 mg/1 based on influent and effluent measurements of 90 and
98 mg/1 respectively.
A chlorine residual of 2 ppm was measured in the effluent immediately
prior to discharge.
INVENTORY
1. Bar rack.
2. Imhoff tank.
3. Trickling filter.
4. Oxidation ponds.
5. Chlorination.
-------
Kendall Complex Sewage Treatment Plant
March 16, 1971
Page 2
DISCUSSION
(Because of known low flow conditions and the absence of any flow
measuring devices, loading calculations cannot be considered valid when
based on the average design flow.)
BOD^, COD and TOC removal efficiencies were 85, 75 and 457»
respectively with corresponding effluent concentrations of 47, 177 and
85 mg/1.
The settleable solids removal efficiency equalled 60% with .2 ml/1
being measured in the effluent. The influent total suspended solids
level of 90 mg/1 increased to 98 mg/1 in the effluent.
Nutrient effluent concentrations were relatively insignificant:
ammonia nitrogen: 4.98 mg/1; nitrate-nitrite as N: .01 mg/1; total
phosphorus: 2.3 mg/1.
RECOMMENDATIONS
The physical appearance of the treatment plant was good with all
mechanical units operational.
The facility is maintained by a Dade County employee, licensed
class "C", and a regular maintenance crew.

Kings Inn Hotel Sewage Treatment Plant
500 Deer Run
Miami Springs, Dade County, Florida
March 16, 1971
INTRODUCTION
The Kin^s Inn' Hotel Sewage Treatment Plant was inspected and
sampled on December 7, 1970 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant is a Chicago Pump Rapid Bloc package plant which utilizes the
complete mix process and chlorination prior to discharge to a drain-
field. The inspection was conducted in conjunction with Mr. James Binger,
maintenance supervisor.
RESULTS
Treatment efficiencies for the critical parameters were adequate.
BOD^ removal was 84%, with 11.5 mg/1 being measured in the effluent.
The influent settleable solids level of 2.5 ml/1 was reduced 100%.
Total suspended solids removal efficiency was 48%, leaving 26 mg/1 in
the effluent.
A chlorine residual of 5 ppm was measured in the final effluent
immediately prior to discharge.

3. Aeration tank; diffused air system.
4. Secondary sedimentation.
5. Chlorine contact.
6. Dosing tank.
7. Aerobic digester; diffused air system.
RESULTS
BOD^} COD and TOC removal efficiencies were 84, 76.8 and 44%
respectively with estimated loadings of 1.92, 11.51 and 4.67 lbs. per
day based on the average design flow.
Settleable solids were removed 100%, while the efficiency for
suspended solids was 48%. This produced an effluent concentration of
26 mg/1 and an estimated loading of 4.34 lbs. per day.
Ammonia nitrogen, nitrate-nitrite as N and total phosphorus effluent
concentrations were measured at 11.2, 13 and 5.2 mg/1 producing loadings
of 1.87, 2.17 and .87 lbs. per day.
DISCUSSION
Based on the chemical data and visual inspection, only one recommenda-
tion is necessary. Chlorine is added drop-wise and the rate of flow is
controlled by a valve. This should be replaced with a liquid chlorinating
device to insure proper disinfection.
The treatment plant is operated by the maintenance staff of the hotel.
None of the personnel are certified.

Lakeview Garden Apartments Sewage Treatment Plant
7711 Miller Drive
Westwood Lakes, Dade County, Florida
March 15, 1971
INTRODUCTION
The Lakeview Garden Apartments Sewage Treatment Plant was
inspected and sampled on January 12, 1971,- by Kenneth Schang. Grab
samples of the influent and effluent prior to chlorination were
obtained. The treatment plant is a W & S Contact Stabilization package
unit with chlorination prior to discharge to a drainfield. Initial
contact was made through the apartment manager.
SUMMARY AND CONCLUSIONS
Removal of BOD^ equalled 89% leaving an effluent concentration of
24 mg/1.
There were no settleable solids measured in the effluent. Total
suspended solids effluent concentration equalled 26 mg/1 indicating a
removal efficiency of 63.9%. The chlorine residual measured in the
dosing tank was .1 ppm.
INVENTORY
1. Contact tank; diffused air system.
2. Secondary sedimentation.
3. Reaeration tank; diffused air system.
4. Dosing tank plus chlorination.
5. Aerobic digester; diffused air system.

RESULTS
Removal of BOD^ # cod an<3 TOC was 89, 94.3 and 94.8% respectively.
The corresponding estimated stream loadings were 6, 8.5 and 3.25 lbs.
per day based on the average design flow of .03 MGD.
Settleable solids removal efficiency was 100%; however, a total
suspended solids estimated loading of 6.5 lbs. per day was produced after
63.9% of the influent value was removed.
Ammonia nitrogen, nitrate-nitrite as N, and total phosphorus
estimated loadings were calculated at .78, .55 and 2.8 lbs. per day.
DISCUSSION
One recommendation is that the present chlorine system be substituted
by an automatic feed chlorinator to insure proper disinfection.
No licensed operator has been retained to maintain the system.
Overall plant condition was adequate.

Report on Waterborrie Wastes from
Medley Mobile Home Court Sewage Treatment Plant
8181 S. River Drive
Medley, Dade County, Florida
March 19, 1971
INTRODUCTION
The Medley Mobile Home Sewage Treatment Plant was inspected
and sampled on January 6, 1971 by Kenneth Schang. Grab samples
of the influent and effluent after chlorination were obtained. The
treatment plant is a W & S Contact Stabilization unit with tertiary
filtration and chlorination prior to discharge to a soakage pit.
SUMMARY AND CONCLUSIONS
Removal of BOD exceeded 95% producing 10 mg/1 effluent con-
centration .
The influent settleable solids level of 0.7 ml/1 was reduced to
0.1 ml/1 indicating an efficiency of 85.77«. This particular efficiency
value is lower than what would be expected for a tertiary system, and
even though the effluent contains only 0.1 ml/1 settleable solids, this
condition might be investigated.
A chlorine residual of 1.5 ppm was measured in the dosing tank
prior to discharge.
INVENTORY
1. Comminutor.
2. Contact tank; diffused air system.
3. Secondary sedimentation.

4. Stabilization tank, diffused air system.
5. Equalizing tank + chlorination.
6. Tertiary filters.
7. Dosing tank.
8. Soakage pit.
9. Aerobic digester; diffused air system.
RESULTS
The effluent loadings for BOD, COD and TOC were 0. 25, 1.35 and
0.6 lbs. per day based on a flow of 3000 GPD indicated by the flow
meter at the time of inspection. The corresponding removal efficien-
cies were 95.9, 92.8 and 79.7% respectively. Total suspended solids
removal was 77.97o producing an effluent discharge of 0.68 lbs. per
day. The effluent settleable solids were measured at 0.1 ml/1
produced from a removal efficiency of 85.7%.
Ammonia nitrogen, nitrate-nitrite nitrogen and total phosphorus
concentrations equalled 2.2, 0.4 and 8.8 mg/1.
DISCUSSION
An obvious problem exists with respect to solids removal. A
77.97o removal of suspended solids and 85.7% removal of settleable
solids instituted by a tertiary treatment system does not seem to be
adequate. It is recommended that the efficiency of the filters with
respect to solids removal be investigated.
The plant appeared to be in good physical condition.

Report on Waterborne Wastes from
Miami Shores Condominium Sewage Treatment Plant
1700 N.E. 105th Street
Miami Shores, Dade County, Florida
February 23, 1971
INTRODUCTION
The Miami Shores Condominium Sewage Treatment Plant was inspected
and sampled on December 2, 1970 by Kenneth Schang. Grab samples
of the influent and effluent after chlorination were obtained.
The treatment plant is a Chicago Pump-Rapid Bloc package unit with
chlorination prior to discharge to Biscayne Bay. Initial contact
was made through Mr. Dick Groendyke, manager of the condominium.
SUMMARY AND CONCLUSIONS
Removal of BOD^ was 82.3% efficient and 59 mg/1 was the effluent
concentration. The effluent contained a higher level of settleable
solids than the influent, 2.5 vs 4.0 ml/1, which implies considerable
inadequacy in the treatment system.
A chlorine residual of 2 ppm was measured in the chlorine contact
chamber just prior to discharge.
INVENTORY
1. Comminutor, located at the influent to the wet well.
2. Aeration tank, diffused air system.
-------
Miami Shores Condominium Sewage Treatment Plant
February 23, 1971
Page 2
3. Secondary sedimentation.
4. Chlorination.
5. Aerobic digestion, diffused air with waste sludge being
trucked away.
RESULTS
Removal of BOD^, COD and TOC was 82.3, 68.7 and 66.1% respectively
with effluent concentrations of 59, 223 and 55 mg/1 respectively, and
loadings of 9.84, 37.2 and 9.17 lbs. per day respectively based on
the average design flow of .02 MGD.
Solids removal was at an equally low level; total suspended solids
were measured at 80 mg/1 in the effluent for a removal efficiency of
607c. Settleable solids were more prevalent in the effluent than the
influent with 2.5 ml/1 and 4 ml/1 being the respective measured values.
Organic nitrogen loading was calculated as 3.20 lbs. per day,
nitrate-nitrite nitrogen loading was .034 lbs. per day, and total
phosphorus was being discharged at the rate of 1.73 lbs. per day.
DISCUSSION
The chemical data coupled with a visual inspection indicates that a
problem caused by surging exists in this particular system. The
relatively high level of organic nitrogen in the effluent shows that
the sewage is not receiving adequate detention. In addition, flow in
the chlorine contact chamber appeared to be significantly higher than
the design value. The recommendation is for a more detailed investiga-
tion of the flow condition to evaluate if a critical overload is in
fact occuring and what can be done to alleviate the problem.

The return sludge line from the secondary clarifier to the
aeration tank did not appear to be delivering an adequate amount of
solids. It is recommended that this condition also be investigated.
In addition, a flow meter should be installed.
A licensed operator was not maintaining the treatment plant at the
time of inspection. However, a local consulting company was recently
retained by the owners of the Shores Condominium and a class "C"
operator, Mr. Pullam, will now be in charge of operation.

Operation Report on
Miami Springs High School Sewage Treatment Plant
750 Dove Avenue
Miami Springs, Dade County, Florida
March 11, 1971
INTRODUCTION
The Miami Springs High School Sewage Treatment Plant
was inspected and sampled on January 15, 1971, by Kenneth Schang.
Grab samples of the influent and effluent after chlorination were
obtained. The treatment plant is a Chicago Pump-Rated Aeration
package unit with chlorination prior to discharge to a drainfield.
The plant inspection was conducted in conjunction with Mr. D. Pullam,
plant operator.
SUMMARY AND CONCLUSIONS
BOD removal efficiency equalled 71 .'87o with an effluent concentrat-
ion of 66 mg/1.
Total suspended solids removal efficiency was 5.8% for a reduction
of the 138 mg/1 influent value to 130 mg/1.
A chlorine residual of 2 ppm was measured in the effluent immediate-
ly prior to discharge.
INVENTORY
1. Comminutor.
2. Aeration tank; diffused air system.
3. Secondary sedimentation.
4. Dosing tank plus chlorination.
-------
Miami Springs High School Sewage Treatment Plant
March 11, 1971
Page 2
RESULTS
The influent settleable solids value of 2.5 ml/1 was increased to
3 ml/1 in the effluent. Total suspended solids removal efficiency was
only 5.87» with a corresponding effluent concentration of 130 mg/1.
BOD^, COD and TOC effluent concentrations were 66, 221, and
55 mg/1 respectively with corresponding removal efficiencies of
71.8, 65.4, and 59.3%.
The Kjeldahl nitrogen effluent concentration was significant at
55.1 mg/1. Nitrate-nitrite as N and total phosphorus effluent concentra-
tions were .03 and 9 mg/1 respectively.
DISCUSSION
At the time of inspection a significant surge went through the
plant, carrying solids out of the secondary sedimentation tank. The
relatively high Kjeldahl nitrogen value substantiates the significance
of this hydraulic overload by indicating that insufficient detention time
is a problem. One recommendation is to investigate the surging con-
ditions and determine how the problem might be alleviated.
The age of the plant contributed to a "below average" physical
appearance although all mechanical units were operational.
Mr. Pullam is licensed class "C".

Report on Waterborne Wastes from
Midway Mall Sewage Treatment Plant
West Flagler Street and the Palmetto Expressway
March 22, 1971
INTRODUCTION
The Midway Mall Sewage Treatment Plant was inspected and
sampled on December 8, 1970 by Kenneth Schang. Grab samples of the
influent and effluent after chlorination were obtained. The treatment
plant consists of two Davco Contact Stabilization package units in
parallel, each capable of treating 0.06 MGD, with tertiary filtration
and chlorination prior to discharge to the North Line Canal. Only
one plant was in operation at the time of inspection; this plant was
being operated as an extended aeration system until both plants are
placed in operation. The inspection was conducted in conjunction
with Mr. Richard Kasch, plant operator.
SUMMARY AND CONCLUSIONS
BOD was reduced 98.3% to 4.5 mg/1 and no settleable solids
were measured in the effluent.
The chlorine residual present in the holding tank equalled 2 ppm.
Total suspended solids removal efficiency equalled 87.8% with
47 mg/1 being the effluent concentration.

INVENTORY
1. Comminutor.
2. Aeration tank - contact tank, diffused air system.
3. Secondary sedimentation.
4. Reaeration tank, diffused air system.
5. Pre-chlorination.
6. Dosing tank.
7. Tertiary filters.
8. Final holding tank.
9. Aerobic digester, waste sludge hauled away; diffused air
system.
RESULTS
BOD, COD and TOC removals were 98.3, 94.2 and 94.3% respectively
with effluent concentrations equalling 4.5, 38 and 9 mg/1. Utilizing
an average design flow figure of 0.06 MGD for the one plant in operation,
the corresponding estimated loadings are 2.25, 19 and 4.5 lbs. per day.
Removal of settleable solids was 100% effective. Forty-seven mg/1
of TSS were measured in the effluent which indicates that approximately
23.5 lbs. per day was being discharged to the canal. Total suspended
solids removal was 87.8% efficient.
Nutrient concentrations were relatively insignificant: ammonia
nitrogen: 1.0 mg/1, nitrate-nitrite as N: 3.4 mg/1 and total
phosphorus: 0.8 mg/1. The corresponding estimated loadings were
0.85, 1.7 and 0.4 lbs. per day respectively. These were calculated
utilizing the average design flow of 0.06 MGD.
-------

DISCUSSION
Overall plant operation appeared to be very good; however,
the suspended solids removal efficiency was not adequate. It is
recommended that the treatment efficiency of the tertiary filters be
evaluated in order to determine whether they are functioning.
Mr. Richard Kusch, employed by Dade County as a treatment plant
operator, is licensed class "B".

Report on Waterborne Wastes from
Miller Lake Apartments Sewage Treatment Plant
5500 S.W.,77th Court
Westwood Lakes, Dade County, Florida
March 19, 1971
INTRODUCTION
The Miller Lake Apartments Sewage Treatment Plant was inspected
and sampled on January 12, 1971 by Kenneth Schang. Grab samples
of the influent and effluent after chlorination were obtained. The
plant consists of a W & S Contact Stabilization package unit with
tertiary filtration and chlorination prior to discharge to a soakage
pit.
SUMMARY AND CONCLUSIONS
BOD removal was 70.9% effective, and the effluent concentration
was 46 mg/1.
The influent total suspended solids concentration of 124 mg/1 was
reduced 79% to 26 mg/1.
A chlorine residual of 0.25 ppm was measured in the effluent
immediately prior to discharge.
INVENTORY
1. Basket strainer.
2. Aerated surge tank, diffused air system.
3. Contact tank; diffused air system.
4. Secondary sedimentation.
5. Stabilization tank, diffused air system.

6. Equalizing tank and chlorination.
7. Jetflo tertiary filtration.
8. Dosing tank.
9. Aerobic digester, diffused air system.
DISCUSSION
An influent settleable solids level of 2 ml/1 was reduced to
zero ml/1 in the effluent. Total suspended solids were reduced
797» to 26 mg/1 with a corresponding stream loading of 0.65 lbs. per
day based on the measured flow of 0.003 MGD.
BOD, COD and TOC removal efficiencies were 70.9, 65.7 and 30%
respectively with corresponding effluent concentrations of 46, 136
and 42 mg/1 and loadings of 1.15, 3.4 and 1.05 lbs. per day respectively.
Nutrient effluent concentrations and loadings for ammonia nitrogen,
nitrate-nitrite as N, and organic nitrogen were as follows: 20.0 mg/1,
0.5 lbs. per day; 0.04 mg/1, .001 lbs. per day; and 2.3 mg/1, 0.058 lbs.
pe^r day. The total phosphorus concentration in the effluent was 12.1 mg/1.
RECOMMENDATIONS
Based on the chemical evaluation this treatment plant is not effect-
ing the design removal efficiencies. From the visual inspection no
conclusions could be made excepting that the plant does not have adequate
solids levels built up because it is a relatively new facility. An
additional evaluation is recommended at some later time.
The plant is maintained by a class "C" operator.

Report on Waterborne Wastes from
Monsignor Pace High School Sewage Treatment Plant
15600 N.W. 32nd Avenue
Opa Locka, Dade County, Florida
February 23, 1971
INTRODUCTION
The Monsignor Pace High School Sewage Treatment Plant was
inspected and sampled on December 1, 1970 by Kenneth Schang and
Frank Ansley (Dade County Pollution Control Inspector). Grab
samples of the influent and effluent after chlorination were obtained.
The extended aeration treatment process is utilized with chlorination
prior to discharge to the Biscayne Canal. The inspection was conducted
in conjunction with Brother Clement who operates and maintains the
system.
SUMMARY AND CONCLUSIONS
Treatment efficiency was variable. BOD removal approached 87%
with an effluent concentration of 17 mg/1 and a loading of 4.25
lbs. per day being placed on the Biscayne Canal.
Total suspended solids removal efficiency was 67.3%, with 8.51
lbs. per day being discharged based on the average design flow of
.03 MGD and an effluent concentration of 34 mg/1.
Adequate chlorination was provided with the effluent containing
a 1.8 ppm residual.
A flow meter is required at this plant.

INVENTORY
1. Bar rack and comminutor in parallel, at influent to wet well.
2. Aeration tank.
3. Secondary sedimentation.
4. Chlorine contact chamber.
5. Anaerobic digestion, sludge holding tank.
RESULTS
Based on the average design flow of .03 MGD, the BOD^, COD and TOC
loadings were 4.25, 14.26 and 4.75 lbs. per day respectively, with
effluent concentrations equalling 17, 57 and 19 mg/1 respectively,
and removal efficiencies of 86.9, 91.4 and 81.9% respectively.
Solids removal was somewhat less successful: total suspended solids
were 67.3% removal with 34 mg/1 or 8.51 lbs. per day being discharged
to Biscayne Canal. Settleable solids were measurable at .1 ml/1
in the effluent with only .2 ml/1 present in the influent.
Nutrient loadings were: ammonia nitrogen 1.50 lbs. per day,
nitrate-nitrite nitrogen 7.13 lbs. per day, and total phosphorus
2.13 lbs. per day. The relatively high concentration of nitrate-nitrite
nitrogen (28.5 mg/1) provided evidence of long detention times, allowing
sufficient time for excessive nitrification, implying that average flow
is less than the design flow.
DISCUSSION
The plant is in poor mechanical condition. It is recommended
that the necessary funds be provided to place the treatment plant

back in good working order.
The aeration tank appeared to have a low solids level, possibly
induced by a low loading condition because of the average daily
flow being less than the design flow.
Brother Clement is not a licensed treatment plant operator.

Operation Report on
My-Am-EE Mobile Home Park Sewage Treatment Plant
9000 S.W. Grand Canal Drive
Miami, Dade County, Florida
January 25, 1971
INTRODUCTION
The My-Am-EE Mobile Home Park Sewage Treatment Plant was inspected
and sampled on December 17, 1970, by Kenneth Schang and Gary Cohen
(Dade County Pollution Control Inspector). Grab samples of the
influent and effluent prior to chlorination were obtained. The
facility incorporates a Chicago Pump Extended Aeration package system
with an oxidation pond to treat waste prior to the effluent being
discharged into the Tamiami Canal. Inspection was conducted in
conjunction with Gene Schley who maintains the treatment plant.
SUMMARY AND CONCLUSIONS
Design capacity for the treatment plant is .03 MGD with effluent
BOD^ concentration at 21.5 ppm. Although this is a removal efficiency
of 96.3% the loading placed on the canal is 5.38 lbs. per day. Although
an effluent settleable solids concentration of .2 ml/1 was present,
it is noted that the oxidation pond should restrict the discharge of
any settleable solids inherent to an activated sludge system.
-------
My-Am-EE Mobile Home Park
Sewage Treatment Plant
January 25, 1971
Page 2
The plant accomplished 90% + removal of all chemical parameters
utilized in the evaluation excepting total organic carbon where
efficiency dropped to 15%. Based on these data the system must be
classified as "good" with regard to operating efficiency standards
for Dade County.
INVENTORY
The treatment plant incorporates:
1. Comminutor
2. Two aeration tanks in parallel, diffused air systems, with
15,000 GPD capacity each.
3. Two secondary sedimentation tanks in parallel, 15,000 GPD
capacity each.
4. Oxidation pond receiving the combined effluents.
5. Chlorination of the overflow from the oxidation pond.
6. Aerobic holding tank for waste sludge, with disposal by
septic tank truck.
RESULTS
Effluent BOD^, COD and T0C concentrations were 21.5 ppm, 100 ppm
and 57 ppm respectively, which constitutes a treatment efficiency of
96.3, 95.8 and 75.27o with respect to these chemical parameters.
A .2 ml/1 settleable solids concentration produced a removal
efficiency of 99.97o.
-------
My-Am-EE Mobile Home Park
Sewage Treatment Plant
January 25, 1971
Page 3
Chlorine residual was 10 ppm, substantially above the accepted
criteria, and contact time should provide for a thorough bacterial kill.
Nutrient loadings for NH^-N, nitrate-nitrite, and total phosphorus
were 2.23, .05 and 3.83 lbs. per day, based on effluent concentrations
of 8.9, 0.2 and 15.3 mg/1 for the average design flow.
DISCUSSION
The oxidation pond contained considerable organic solids which
might hamper the treatment process. It is recommended that this situation
be corrected by periodic cleaning of the pond. In addition, aeration by
a diffused air system could improve the overall treatment by providing
sufficient oxygen even on days of retarded biological activity.
A scum on the aeration tanks was noted. This might contribute to a
lowered treatment efficiency and should be investigated.
If possible, utilization of a drainfield to accept the effluent
should be substituted for the present canal discharge.
The treatment plant had a "good" overall appearance although minor
attention should be paid to the sludge present in the oxidation pond.
None of the maintenance personnel were licensed as operators although
Mr. Gene Schley was attending a short course to aid in exam preparation.

Report on Waterborne Wastes from
Naval Air Station Sewage Treatment Plant
S.W. 122nd Avenue and 152nd Street
Howard, Dade County, Florida
March 19, 1971
INTRODUCTION
The Naval Air Station Sewage Treatment Plant was inspected and
sampled on January 12, 1971 by Kenneth Schang. Grab samples of the
influent and effluent prior to chlorination were obtained. The
treatment plant utilized the conventional activated sludge process
with chlorination prior to discharge to a drainfield. The inspection
was conducted in conjunction with a member of the maintenance crew
that operates the plant.
SUMMARY AND CONCLUSIONS
An influent BOD concentration of 39.5 mg/1 was reduced 31.6% to
27 mg/1.
Total suspended solids removal efficiency was 45.87o and the
effluent concentration was 26 mg/1.
At the time of inspection the chlorination system was not operating
properly and there was no chlorine residual measurable in the effluent.
The operation of the treatment plant is not conducted by a
licensed operator.
INVENTORY

2. Primary sedimentation.

March 19, 1971
Page 2
3. Aeration tanks, mechanical aeration.
4. Secondary sedimentation.
5. Ghlorination.
6. Anaerobic sludge digester; waste sludge to drying beds.
DISCUSSION
(Loadings are insignificant due to the low flow condition and
the absence of any flow measuring devices.)
BOD, COD and TOC effluent concentrations were 27, 66 and 12 mg/1
respectively with corresponding removal efficiencies of 31.6, 89.4
and 67.6%.
The low settleable solids influent level of 0.5 ml/1 was reduced
to zero ml/1 in the effluent. Total suspended solids removal efficiency
was 45.87. for an effluent concentration of 26 mg/1.
Effluent concentrations for ammonia nitrogen, nitrate-nitrite as
N, and total phosphorus were 9.1, 0.01 and 7.1 mg/1 respectively.
RECOMMENDATIONS
Most of the operational problems noticed could be corrected by
a licensed operator. The retention of a licensed operator to take over
plant operation is of primary concern.
Generally the plant is underloaded, and the mixed liquor suspended
solids were not of sufficient concentration to effect proper treatment.
Since the plant is comprised of two systems operating in parallel, a
total shut down of one unit may help the low loading condition.
-------
Naval Air Station Sewage Treatment Plant
March 19, 1971
Page 3
At the time of inspection, the chlorination system was not in
operation. Closer inspections of this system are recommended.
The capacity of the mechanical aerators to provide adequate
dissolved oxygen appeared questionable due to their size and
design. Since the plant was constructed in 1942, installation of
more modern aerator units might facilitate the treatment process.
Overall plant appearance was not adequate. Although all
mechanical units were operational the total plant system needed
additional work and maintenance.

Report on Waterborne Wastes from
Palm Springs Garden Condominium Waste Water Treatment Plant
170 Royal Palm Road
Hialeah Gardens, Dade County, Florida
March 19, 1971
INTRODUCTION
The Palm Springs Garden Condominium Waste Water Treatment Plant
was surveyed during the period December 6-8, 1970. The survey
was begun as a major treatment plant effort, but was terminated by
mutual agreement of Mr. Robert Evans, Enforcement Officer of Dade
County Pollution Control Board, and the authors of this report.
The plant is a package treatment system and there appeared to be no
reason for an extensive sampling program. Two Sirco electric automatic
samplers were utilized to collect two 24-hour composites of influent
and effluent (after chlorination). Messrs. Terry Davis and George
Egermier were the sample collectors. Primary contact was Mr. Greenberg
of Gelvan, Inc.
SUMMARY AND CONCLUSIONS
The average flow during the study period was 0.02 MGD. The average
five-day biochemical oxygen demand (BOD) and total suspended solids
loads discharged during the study were 6.5 and 12 lbs. per day respect-
ively. The plant did not provide 907„ removal of BOD or total suspended
solids. The average removal efficiencies for BOD and total suspended
-------
Palm Springs Garden Condominium Waste Water Treatment Plant
March 19, 1971
Page 2
solids were 7,6.8 and 64.1% respectively. The average removal
efficiencies and loads were calculated from the daily data.
The following are recommended to improve waste treatment by
this plant:
1. The operating criteria be reevaluated.
2. The plant should be operated by a licensed operator.
INVENTORY
The unit is a Davco contact stabilization plant, manufacturer's
model No. 12DAc50C, with extended air feature. In the contact
stabilization mode, it is designed for a flow of 0.05 MGD, while in
the extended air mode the design flow is 0.025 MGD. During the
survey, the plant was being operated in the contact stabilization
mode. In this configuration, the tank has the following major
components:
1. Contact tank with air diffusers.
2. Secondary clarifier with mechanical sludge collector.
3. Reaeration tank with air diffusers.
4. Two stage aerobic digester with air diffusers.
5. Inlet bar screen.
6. Chlorine contact chamber (with change from liquid to
gas chlorination).
In the extended air operation, the aerobic digester tanks and the
contact tanks are used as aeration tanks.
-------
Palm Springs Garden Condominium Waste Water Treatment Plant

RESULTS
The average flow during the study period was 0.02 MGD. The
average influent and effluent BOD concentrations were 173 and
41 mg/1 (6.5 lbs. per day) respectively. The average total suspended
solids concentrations were influent, 212 mg/1, and effluent, 75.5 mg/1
(12 lbs. per day). The average BOD and total suspended solids
removal efficiencies were 76.8 and 64.1% respectively.
The chlorine residual in the effluent was only measured on
December 7, 1970, when it was greater than 10 mg/1. The bacterial
concentrations during the study were low.
Most of the nutrients discharged by the plant were in the form
of ammonia nitrogen, 15.3 mg/1 (2.5 lbs. per day), and total phosphorus,
9.6 mg/1 (1.5 lbs. per day).
The daily data are presented in the attached Field and Data
Summary Sheets.
DISCUSSION
There is a background of operating problems at this plant, the
present owner is making an effort to correct this situation. However,
a complete reevaluation of operating procedure is necessary. This
plant should be operated by a licensed operator, but at the present
time it is not.

Report on Waterborne Wastes from
Palm Springs General Hospital Sewage Treatment Plant
1479 W. 49th Street
Hialeah, Dade County, Florida
March 19, 1971
INTRODUCTION
The Palm Springs General Hospital Sewage Treatment Plant was
inspected and sampled on January 5, 1971 by Kenneth Schang. Grab
samples of the influent and effluent after chlorination were
obtained. The treatment plant utilizes the extended aeration process
with chlorination prior to discharge to the Little River Canal.
SUMMARY AND CONCLUSIONS
The treatment plant effected 80.9% removal of BOD for an effluent
concentration of 29 mg/1.
Total suspended solids removal efficiency equalled 89.6% with
an effluent concentration of 21 mg/1.
A chlorine residual of ^10 ppm was measured in the effluent
immediately prior to discharge.
INVENTORY
1. Aeration tanks; diffused air system.
2. Secondary sedimentation.
3. Chlorine contact.
4. Aerobic digester, diffused air system.
-------

March 19, 1971
Page 2
DISCUSSION
BOD, COD and TOC removal efficiencies equalled 80.9, 80.9 and
39.37o respectively with corresponding effluent concentrations of
29, 137 and 44 mg/1. The discharge loadings were calculated as:
BOD, 3.39; COD, 16; and TOC, 5.13 lbs. per day based on the measured
flow of 0.014 MGD.
Total suspended solids removal efficiency equalled 89.6% based on
an effluent concentration of 21 mg/1 and this produced a loading of
2.45 lbs. per day. The influent settleable solids level of 3 ml/1
was reduced 96.7% to 0.1 ml/1 in the effluent.
Nutrient concentrations and loadings were as follows: organic
nitrogen: 11.6 mg/1 and 1.34 lbs. per day; nitrate-nitrite as N: 0.2 mg/1
and .023 lbs. per day; total phosphorus: 9.8 mg/1 and 1.14 lbs. per day.
RECOMMENDATIONS
The physical appearance of the treatment plant was not good;
more adequate maintenance is necessary.
The visual inspection yielded no recommendations with regard to
plant operation.
Mr. William Case, plant operator, is licensed class "A".

Report on Waterborne Wastes from
Queen's Inn Hotel Sewage Treatment Plant
5335 N.W. 36th Street
Miami Springs, Dade County, Florida
March 19, 1971
INTRODUCTION
The Queen's Inn Hotel Sewage Treatment Plant was inspected and
sampled on January 13, 1971 by Kenneth Schang. Grab samples of the
influent and effluent prior to chlorination were obtained. The
treatment plant utilizes the extended aeration process with tertiary
filtration and chlorination prior to discharge to a drainfield.
SUMMARY AND CONCLUSIONS
An influent BOD of 73 mg/1 was reduced 86.3% to 10 mg/1.
The total suspended solids removal efficiency equalled 80.4%,
producing an effluent concentration of 20 mg/1.
A chlorine residual of 0.5 ppm was measured in the dosing tank
immediately prior to discharge.
INVENTORY
1. Aeration tank; diffused air system.
2. Secondary sedimentation.
3. Tertiary filters.
4. Chlorination.
5. Aerobic digester; diffused air system.
-------
Queen's Inn Hotel Sewage Treatment Plant
March 19, 1971
Page 2
RESULTS
(Low flow and the lack of a flow measuring device did not allow
the loads to be calculated).
Removal efficiencies for BOD, GOD and TOC were 86.3, 71.8 and
62.2% respectively with corresponding effluent concentrations of
10, 69 and 14 mg/1.
The influent settleable solids value of 0.5 ml/1 was reduced to
zero ml/1 in the effluent. The total suspended solids removal
efficiency equalled 80.4% producing an effluent concentration of
20 mg/1.
Nutrient effluent concentrations were as follows: ammonia nitrogen:
18.4 mg/1; nitrate-nitrite as N: 0.1 mg/1; total phosphorus: 5.8 mg/1.
DISCUSSION
The solids levels in the aeration tank appeared to be low due to
the newness of the treatment plant. This condition may have prevented
the system from effecting the removal efficiencies to be expected from a
tertiary plant. The recommendation is to reevaluate this facility at
some later time.
The treatment plant is not operated by a certified operator.

INVENTORY
1. Comminutor.
2. Aeration tanks, diffused air system.
3. Secondary sedimentation.
4. Dosing tank plus chlorination,
5. Aerobic digester; diffused air system.
RESULTS
Removal of BOD, COD and TOC was 95.2, 91 and 74.17<, respectively.
The corresponding estimated loadings were 2.18, 7.63 and 3 lbs. per
day based on an average design flow of 0.015 MGD.
Efficiency of treatment with regard to solids was excellent.
The influent total suspended solids level of 332 mg/1 was reduced
93.77» to 21 mg/1. An estimated discharge of 2.63 lbs. per day was
produced. Settleable solids were reduced to zero ml/1 in the
effluent.
Estimated nutrient loadings were calculated as follows:
ammonia nitrogen: 1.70 lbs. per day, nitrate-nitrite as N:0.025 lbs.
per day, and total phosphorus: 1.05 lbs. per day.
DISCUSSION
From the visual inspection and chemical analysis the plant can be
considered as operating very well. No recommendations are in order.
At the time of inspection, Mr. Jack Coles was being considered as

Report on Waterborne Wastes from
Saratoga Springs Apartments Sewage Treatment Plant
400 N. Royal Poinciana Boulevard
Miami Springs, Dade County, Florida
March 18, 1971
INTRODUCTION
The Sararoga Springs Apartments Sewage Treatment Plant was
inspected and sampled on January 7, 1971 by Kenneth Schang. Samples
of the influent and effluent were obtained. The treatment plant consists
of a Seco Extended Aeration package unit with chlorination prior to
discharge to a drainfield. The inspection was conducted in conjunction
with Mr. James Montague, apartment manager.
SUMMARY AND CONCLUSIONS
BOD removal equalled 52.27„ with 76 mg/1 present in the effluent.
The settleable solids removal efficiency equalled 90% with 0.5 ml/1
in the effluent.
INVENTORY
1. Aeration tank; diffused air system.
2. Secondary sedimentation.
3. Chlorination.
4. Aerobic digester; diffused air system.
RESULTS
Removal of BOD, COD and TOC was calculated at 52.2, 83.4, and
697o with estimated discharge loadings of 8.24, 16.69 and 4.88 lbs.
per day based on the average design flow of 0.013. MGD.
-------
Saratoga Springs Apartments Sewage Treatment Plant
March 18, 1971
Page 2
The influent settleable solids level of 5 ml/1 was reduced
90% to 0.5 ml/1. Efficiency with respect to total suspended
solids removal equalled 88.7% producing an estimated stream loading
of 9.54 lbs. per day.
Nutrient concentrations were: ammonia nitrogen: 2.8 mg/1,
organic nitrogen: 7.7 mg/1, nitrate-nitrite as N: 12.4 mg/1 and total
phosphorus 6.9 mg/1. The corresponding loadings are 0.3, 0.83, 1.34 and
0.75.lbs. per day respectively.
DISCUSSION
1. Overall discussion with the manager yielded information that
chlorine was added in the first aeration tank.
2. Solids levels appeared critically low in the aeration tank; color
was not good.
3. Plant operation is conducted by Mr. James Montague, apartment
manager.
Mr. Montague is not certified as a treatment plant operator.
The recommendation is that a licensed operator be contracted until
such time as Mr. Montague can obtain certification.

Report on Waterborne Wastes from
Sea Glades Motel Sewage Treatment Plant
S.W. 332nd Street and U.S. 1
Florida City, Dade County, Florida
March 18, 1971
INTRODUCTION
The Sea Glades Motel Sewage Treatment Plant was inspected and
sampled on January 8, 1971 by Kenneth Schang. Grab samples of
the influent and effluent after chlorination were obtained. The
treatment plant utilizes the extended aeration process with chlorina-
tion and open sand filters prior to discharge to a soakage pit.
The inspection was conducted in conjunction with Mr. S. Nicotra, motel
owner.
SUMMARY AND CONCLUSIONS
The treatment plant effected 82.7% removal of BOD prior to the
final filtration process. This allowed an effluent concentration of
23 mg/1.
The influent total suspended solids value of 90 mg/1 was reduced
67% to 30 mg/1.
A chlorine residual of 1.5 ppm was measured in the effluent
immediately prior to discharge to the sand filters.
INVENTORY
1. Basket strainer.
2. Aerated surge tank; diffused air.
3. Aeration tank, diffused air.

4. Secondary sedimentation.
5. Chlorination, chlorine contact tank.
6. Dosing tank.
7. Open sand filter.
8. Aerobic digester; diffused air with waste sludge to be hauled
away.
DISCUSSION
(Loads are insignificant due to an extremely low flow.)
Removal of BOD, COD and TOC was 82.7, 64.6 and 47.7% respectively
with corresponding effluent concentrations of 23, 131 and 34 mg/1.
Total suspended solids were reduced from 90 mg/1 to 30 mg/1 for a
removal efficiency of 67%. Settleable solids efficiency was 98.37»
with an effluent level of 0.1 ml/1.
Nutrient concentrations were as follows: ammonia nitrogen: 18.2 mg/1;
organic nitrogen: 1.3 mg/1; nitrate-nitrite as N: 0.2 mg/1; total
phosphorus: 0.5 mg/1.
RECOMMENDATIONS
An adequate evaluation of this treatment plant was complicated by
the fact that sufficient solids had not accumulated in the aeration
tanks due to the newness of the system. A more representative evaluation
is recommended at some later date.
Plant operation is conducted by Mr. S. Nicotra, motel owner.
Mr. Nicotra is not certified as an operator.

Report on Waterborne Wastes from
Seventy-Ninth Street Shopping Center Sewage Treatment Plant
3015 N.W. 79th Street
Miami, Dade County, Florida
March 18, 1971
INTRODUCTION
The Seventy-Ninth Street Shopping Center Sewage Treatment Plant
was inspected and sampled on January 13, 1971 by Kenneth Schang.
Grab samples of the influent and effluent were obtained. The
treatment plant utilizes the extended aeration process with tertiary
filtration prior to discharge to a drainfield. Mr. Aborn, construction
manager, was the initial contact.
SUMMARY AND CONCLUSIONS
An effluent BOD concentation of 18 ppm indicated a removal
efficiency of 92.8%.
Settleable solids were reduced from 4 ml/1 to zero ml/1 in the
effluent.
The chlorine feed was not operating properly causing a zero
chlorine residual in the final effluent.
INVENTORY
1. Aeration tank; diffused air system.
2. Secondary sedimentation.
3. Equalizing tank.
4. Tertiary filters.
5. Dosing tank plus chlorination.
6. Aerobic digester; diffused air system.
-------
Seventy-ninth Street Shopping Center Sewage Treatment Plant
March 18, 1921
Page 2
RESULTS
BOD, COD and TOC removal efficiencies equalled 92.8, 91.8 and 86.2%
respectively with 18, 79 and 20 mg/1 being the effluent concentrations.
Settleable solids were reduced 100% from 4 ml/1 and total suspended
solids efficiency was 87.7%. The corresponding suspended solids effluent
concentration was 28 mg/1.
Nutrient effluent concentrations were as follows: organic nitrogen:
2.2 mg/1; ammonia nitrogen: 0.2 mg/1; nitrate-nitrite as N: 40 mg/1;
total phosphorus 24 mg/1.
DISCUSSION
A proper chemical evaluation of this treatment plant is difficult
at the present time due to the low loading condition. Visual inspection
did yield information on certain operational inadequacies. There was no
chlorine residual in the final effluent, and pop-ups were present in the
secondary clarifier. Because a licensed operator has not been contracted
by the owner of this facility, it is recommended that one be retained
to take over operational responsibility.

Steak and Brew Restaurant Sewage Treatment Plant
13190 S. Dixie Highway
Miami, Dade County, Florida
February 23, 1971
INTRODUCTION
The Steak and Brew Restaurant Sewage Treatment Plant was inspected
and sampled on December 10, 1970 by Kenneth Schang. Grab samples
of the influent and effluent prior to chlorination were obtained.
The treatment plant is a Marolf Extended Aeration package unit with
chlorination prior to discharge to a drainfield. The inspection was
conducted in conjunction with Mr. James Barlow who operates the system.
SUMMARY AND CONCLUSIONS
Treatment efficiency was better than 98% for all test parameters.
BOD^ removal exceeded 99% with an effluent loading of 1.29 lbs. per day
and a concentration of 10.3 mg/1.
Removal of suspended solids approached 99°L with 3.75 lbs. per day
being discharged based on the average design flow of .015 MGD. No
settleable solids were measured in the effluent.
A chlorine residual of 3 ppm was present in the effluent sample
obtained from the dosing tank.

5. Dosing tank and chlorination.
6. Aerated sludge holding tank.
RESULTS
The treatment plant effected a 99% removal of BOD^, COD and TOC
with the effluent loadings being calculated as 1.29, 6.63 and 2.5
lbs. per day respectively based on the average design flow.
Solids removal proved to be equally as effective. The 40 ml/1
settleable solids present in the influent were completely removed.
Suspended solids removal, although not as efficient, approached 997°.
The analysis showed 30 mg/1 to be the effluent concentration with
3.75 lbs. per day being discharged.
The nutrient loadings were as follows: Kjeldahl nitrogen: .31 lbs.
per day, nitrate-nitrite nitrogen .0025 lbs. per day, and total phosphorus:
.18 lbs. per day.
DISCUSSION
Based on the efficiency evaluation and the visual inspection there
are no recommendations to improve operation.

Report on Waterborne Wastes from
Sweden House Restaurant Sewage Treatment Plant
14875 S. Dixie Highway
Naranja, Dade County, Florida
March 18, 1971
INTRODUCTION
The Sweden House Restaurant Sewage Treatment Plant was inspected
and sampled on December 9, 1970 by Kenneth Schang and Joe Hopson
(Dade County Pollution Control Inspector). Grab samples of the
influent and effluent were obtained. The treatment plant utilizes the
extended aeration process with chlorination prior to discharge to a
drainfield. Initial contact was made through the restaurant manager.
RESULTS
BOD removal efficiency equalled 72.TL producing 17.5 mg/1 in
the effluent.
Settleable solids were reduced to 0 from the influent value of
1 ml/1.
At the time of inspection, the liquid chlorine was not dripping
into the dosing tank due to some malfunction. Although there was no
chlorine residual measurable in the effluent the problem was alleviated
by the manager upon notification.
INVENTORY
1. Primary sedimentation utilizing a septic tank.
2. Aeration tank, diffused air system.
-------
Sweden House Restaurant Sewage Treatment Plant
Page 2
March 18, 1971
3. Secondary sedimentation.
4. Dosing tank plus chlorination.
5. Aerobic sludge digester, diffused air system.
RESULTS
Although treatment efficiencies did not always seem adequate,
effluent discharges and loadings were relatively small.
BOD, COD and TOC estimated loadings were 2.9, 7.34 and 6.26
lbs. per day based on the average design flow of .02 MGD. The
TOC concentration in the effluent was 37.5 mg/1 while the influent
value equalled 25.5 mg/1.
Suspended solids concentrations were relatively low with
14 mg/1 being reduced to 4 mg/1 for a removal of 71.4%. The estimated
loading is insignificant at 0.67 lbs. per day.
The influent settleable solids were reduced to a value of zero in
the effluent.
Nutrient discharge was also small: organic nitrogen: 2.1 mg/1 and
0.35 lbs. per day (estimate), nitrate-nitrite as N: 1 mg/1 and 0.17 lbs.
per day (estimate), and total phosphorus: 12 mg/1 and 2 lbs. per day
(estimate).
DISCUSSION
One recommendation is with regard to the low loading condition
being placed on the treatment plant. Because of this, a proper solids
-------
Sweden House Restaurant Sewage Treatment Plant
March 18, 1971
Page 3
concentration may be difficult to maintain in the aeration tank.
Further investigation toward eliminating this condition is
recommended.
Mr. Jack fioles, plant operator, is licensed class "C".
Geheral plant appearance was good.

Report.on Waterborne Wastes from
Westchester Hospital Sewage Treatment Plant
7500 Coral Way
Coral Gables, Dade County, Florida
March 18, 1971
INTRODUCTION
The Westchester Hospital Sewage Treatment Plant was inspected
and sampled on December 17, 1970 at 11:00 a.m., by Kenneth Schang
and Gary Cohen (Dade County Pollution Control Inspector). Grab
samples of the influent and effluent prior to chlorination were
obtained. The plant is composed of two .015 MGD Chicago Pump-Extended
Aeration package units with effluent being discharged into the Coral
Gables Canal. At the time of inspection only the west plant was in
operation. The inspection was conducted in conjuntion with
Mr. Robert Lacey who maintains the facility.
SUMMARY AND CONCLUSIONS
Operating efficiencies for BOD and settleable solids are adequate.
BOD removal equalled 97.8% with an effluent concentration of
14.6 mg/1 and stream loading 1.82 lbs. per day based on the average
design flow for the operational unit of .015 MGD.
An influent settleable solids loading of ^40 ml/1 was reduced to
0.2 ml/1 producing an efficiency of 99.57«.
The chlorine residual was measured at 1.5 ppm in the contact
chamber, prior to canal discharge.
-------
Westchester Hospital Sewage Treatment Plant
March 18, 1971

INVENTORY
The standard extended air type package plant incorporated:
1. Comminutor.
2. Aeration tanks, diffused air system.
3. Secondary sedimentation, air lifted return sludge.
4. Chlorination prior to canal discharge.
5. Sludge holding tank - anerobic.
RESULTS
All chemical evaluations indicated satisfactory operation.
BOD and TOC removals were 97.8 and 83.87» producing effluent concentra-
tions of 14.6 and 32.5 mg/1. The COD removal was unsatisfactory„
An influent concentration of 479 mg/1 was reduced to 475 mg/1 for a
discharge of 59.4 lbs. per day calculated at an average design flow
of .015 MGD.
The total suspended solids effluent concentration was measured at
114 mg/1 with 14.26 lbs. per day leaving the plant, for an 85.87« removal
efficiency. Settleable solids were reduced from>40 ml/1 to 0.2 ml/1
for an efficiency of 99.5%.
Kjeldahl nitrogen, nitrate-nitrite as N, and total phosphorus
effluent concentrations were 8.4, 1.1 and 5.7 mg/1 respectively, with
1.05, 0.14 and 0.715 lbs. per day respectively being the corresponding
loadings.
-------

March 18, 1971
Page 3
DISCUSSION
The overall appearance of the system appeared adequate with
mechanical units operating properly. However, the following
recommendations are necessary:
1. A closer study of the plant is required primarily due to the
origin of the waste treated and its ultimate disposal to a canal.
2. The local pollution control agency should monitor this treat-
ment plant closely to at least ascertain that proper chlorine residuals
are being maintained; again, this is due to the origin of the waste
being treated.
3. Mr. Lacey is not licensed as an operator.
4. A flow meter should be installed.

Report on Waterborne Wastes from
Winn Dixie Stores Sewage Treatment Plant
1051 S.E. 8th Street
Hialeah, Dade County, Florida
March 18, 1971
INTRODUCTION
The Winn Dixie Stores Sewage Treatment P^ant was inspected and
sampled on December 1, 1970 by Kenneth Schang and Frank Ansley
(Dade County Pollution Control Inspector). Grab samples of the
influent were obtained. The effluent was not sampled because the
tertiary filters were not in operation at the time. Prior to a
return inspection the plan to phase out the treatment plant was
confirmed and the second sampling was cancelled.
The treatment plant utilizes the complete mix process with
tertiary filtration and chloration prior to discharge to a soakage
pit. The inspection was conducted in conjunction with Mr. G. Seller,
P.E. representative of the responsible consulting engineering firm.
INVENTORY
1. Comminutor in parallel with a bar rack.
2. Aeration tank; diffused air system.
3. Settling tubes.
4. Mixed media filter.
5. Chlorination.
6. Aerobic digester; diffused air system.
-------
Winn Dixie Stores Sewage Treatment Plant
March 18, 1971
Page 2
DISCUSSION
BOD, COD and TOC influent values were >770, 4^218 and 1160 mg/1
respectively,,
RECOMMENDATIONS
The influent chemical evaluation is indicative of the type of
waste being received by this treatment plant. The sewage consists
mainly of washdown water and waste water from produce preparation.
Conversation with Mr. Seller yielded information that the treatment
plant had been in trouble quite a number of times. This was
due to the type of waste and inefficiency of the tube settlers.
