WASTE WATER TREATMENT SYSTEM ABERDEEN CHEMICAL PLANT
INTRODUCTION
Wastewater from "the Vinyl, Compound, and Plasticizer areas of the plant is discharged to the waste water treatment ponds for physical and biological treatment prior to discharge to James Creek. The plant has an NPDES permit from the state of Mississippi which outlines Quantities of water contaminants that can be discharged into the creek.
The following summary briefly describes the major units of the ponds and their primary functions.
A. Pond 1
Pond 1 consists of two concrete settling basins that separate PVC resin from the wastewater. The
in the bottom of the basins and is reclaimed by the resin reclaim
B. Pond 3
Fond 3 is a small equalization lagoon in which wastewater pH is adjusted and fertilizer is added. Limited biological treatment occurs in this pond.
C. Biodisc
The biodisc consists of three rotating biological
contactors which are highly aerated and remove
approximately 60% of the
influent Biological
Oxygen Demand (BOD).
D. Pond 4
Pond 4 is a highly mixed and aerated lagoon that accomplishes further BOD removal.
E. Pond 5
Pond f> is a large and partially aerated lagoon in which Biological Total Suspended Solids (TSS) settle out and are biodegraded. A small amount of final BOD removal occurs in Pond 5.
F. Pond 6
Pond 6 is a small lagoon prior to the out fall that settles minor quantities of TSS that carry

over from pond from pond 5. Treated waste water flows from Pond 6 to James Creek.
Storm water accumulated in the plant is discharged from
two storm water pits located on the south-east side of
the plant.
These pits have NPDES permit limits and
must be monitored.
The following is a description of the storm water pits:
a. Storm water flows from the rain sewer into a pit. This pit settles solids out of the water before being discharged.
b. The water is discharged from a weir south of the pit.
d. The pits are dredged as the solids begin to accumulate.
The Breathing Air Compressor has a weir leaving the plant on the west side of the plant.

AMMONIA PROCESS DESCRIPTION
Ammonia is added continuously to the sump in order to fertilize the water prior to biological treatment. Nitrogen is needed for the growth of the microorganisms in pond 3, the biodisc and in ponds 4 and 5.
Anhydrous ammonia is stored under pressure in a 1500 gallon horizontal tank located inside of the acid dike. Ammonia vapor from the tank passes through a pressure regulator, a fine metering valve and a rotameter and is then bubbled into the bottom of the mixing sump.
The ammonia feed rate is set according to the ammonia
concentration in pond 4, which assures that the feed is
sufficient for acceptable biological treatment.
A
typical feed rate of ammonia is approximately 20 lbs/day.

BIODISC PROCESS DESCRIPTION
The water from pond "three gravity flows into the biodisc pump out sump. The biodisc feed pump transfers the wastewater from the pump out sump to the biodisc.
The biodiscs
are covered with a thin
film of
microorganisms, called biomass, which remove BOD and
COD from the water.
In the biodisc the wastewater is
brought into contact with the rotating biological
surfaces.
As the surface rotates, wetted biomass
passes through the atmosphere in order to aerate the
microorganisms.
This transfer of oxygen is necessary
to maintain an aerobic process.
Water flowing through the biodisc has a theoretical resonance time of one hour.

pH CONTROL PROCESS DESCRIPTION
The pH Control system maintains the pH of the waste water in Pond 3 between 6.5 and 10.0 pH units. Concentrated sulfuric acid is used to neutralize water with high pH and soda ash is used to neutralize water with low pH.
The pH is controlled by monitoring the incoming
water with a pH probe located in the Pond 3 mixing sump.
A second pH probe is
on the
of Pond 3
and is
to monitor the Pond
conditions (alarm low = 7
alarm high = 10).
NOTES:
a. High pH usually comes from tank T-460.
b.
Low
pH
usually
comes
from
the
incinerators.

PHOSPHATE fResponsible: Utility Technician]
Check and record the phosphate concentration on Monday, Wednesday, and Friday at the outlet of Pond 4.
The following procedure is used to check the phosphate concentration:
1. Fill the sample cup to the 25 ML mark.
2 Add 3 drops of A-8500 Activator Solution
3. Snap the tip of the Chemet Ampoule in the sample.
4. Mix the contents of the Chemet ampoule.
5. After two minutes compare with color standard (results in parts per million [PPM]).
Replace Chemet Ampoules and Activator Solution at the storeroom.
Fertilizer which contains Phosphate is added to the ponds during cold weather (winter months). If the residual phosphate reading at Pond 4 is greater than 0.4 PPM reduce the amount of phosphate being added.
If algae begins to grow in Ponds 5 or 6 discontinue the addition of phosphate.
The fertilizer is purchased in 20 pound bags from the local Coop. It is stored in the MCC by Pond 3.
The phosphate feed rate is set according to the residual in Pond 4. A typical feed rate is 3/4 of a 20 lbs bag per day.
WASTE WATER TREATMENT SYSTEM ABERDEEN CHEMICAL PLANT
PHOSPHATE PROCESS DESCRIPTION
Phosphate is added to the mixing sump at the Pond 3 inlet during cold weather to fertilize the water prior to biological treatment. Phosphate helps the microorganisms in Pond 3, the biodiscs and in Ponds 4 and 5.
Fertilizer that is 46 percent phosphate is stored in the MCC by Pond 3. It is manually added to the ponds.
The phosphate feed rate is set according to the residual in Pond 4. A typical feed rate is 3/4 of a 20 lbs bag per day.

POND 1
[Responsible: Process Engineering]
Water from the vinyl operations area gravity flows to
two parallel concrete settling basins (Pond 1) at an
average flow of 925 gpm. At the inlet of Pond I is a
small diversion box with isolation valves that can
divert waste water to either the east or the west
basin.
The discharge from each basin joins together
into a common line and gravity flows to Pond 3.
The primary purpose of Pond 1 is to collect PVC resin
by gravity settling. While one basin is being filled
with resin, the other basin is typically blocked in and
being dredged.
The two basins are alternately filled
and dredged as needed. The dredged resin is reclaimed
by the plant and sold as low grade product.
Pond 1 inlet must be tested for VCM once a month. procedure for this testing is as follows:
The
1. Acquire a 60 ML sample bottle from the lab.
2. Draw a sample in the bucket (kept in utilities truck).
3. Fill sample bottle and screw lid on while
under the water.
This insures there is no
air in the sample bottle.
4. Take to G. C. Lab for analysis:
a. Label sample.
b. Log in the date , sample location, and what the sample is being tested for in the "Special Sample Log Book".
c. Place sample in refrigerator.
Resonance time is 4 1/2 hours.

WASTE WATER TREATMENT SYSTEM ABERDEEN CHEMICAL PLANT
Water from Pond 1 gravity flows into a concrete mixing sump at the inlet of Pond 3. Wastewater from the boiler house, compound and plasticizer areas bypass Pond 1 and flow directly to the concrete mixing sump.
pH equalization occurs in this pond through addition of sulfuric acid or soda ash.
Ammonia is added continuously in order to fertilize the water prior to biological treatment.
Phosphate is added to fertilize the water in the winter.
Residence time is about 2 hours.

POND 4 Water gravity flows from the biodisc sump to Pond 4, where it is further treated for BOD removal. Pond 4 is a highly mixed and aerated lagoon. There are eight small aerators located around the periphery on the pond which mix and aerate the water in order to supply oxygen for microbial growth. Flocks of microorganisms are kept in suspension by swirling water flow around the periphery of the pond, which also helps to increase residence time in the pond. Residence time is about 16 hours.

POND Waiter gravity flows from Pond 4 to Pond 5 for final treatment before discharge to James Creek, from Pond 6. Pond 5 is a large, partially mixed, and aerated lagoon that primarily biodegrades biological solids that carry over from Pond 4- There are two large surface aerators on Pond 5 that aerate portions of the pond. A small amount of BOD removal occurs in the aerated zone of the pond and dead biological material is digested by anaerobic processes on the bottom of the pond. Resonance timea. 1 1/2 days to see effects at outfall. b. 4 days to totally clear Pond 5.

WASTE WATER TREATMENT SYSTEM ABERDEEN CHEMICAL PLANT
Water gravity flows from Pond 5 to Pond 6, and is then discharged into James Creek. Minor amounts of suspended solids that carryover from Pond 5 are settled out. The discharge from Pond 6 gravity flows to James Creek over a series of steps in a cascade formation, which aerates the effluent in order to increase the dissolved oxygen content of the discharge.
