The
PDC #1 Landfill facility just west of Peoria, Illinois,
operates an Industrial Wastewater Pretreatment Plant
(IWTP). Our pretreatment discharge permit, number
01-1631, is issued by the Greater Peoria Sanitary
District and conforms with all federal and Illinois
regulations.
We
are fully permitted to handle oily wastewater, restaurant
grease, interceptor wastes, machine coolants and
liquid waste from metal washing operations. And
with 400,000 gallons of tank capacity, our non-hazardous
treatment facility can process up to 100,000 gallons
of liquid per day.

Our
Treatment Process
Our
process generally begins with gravity separation
in our 150,000-gallon batch tanks. Three layers
develop: tramp oils on the top; treatable
water in the middle; and heavy solids on the
bottom.
Treatable
water is removed. Additives are introduced
to adjust pH, precipitate solids and break
oil emulsions. A polymer is introduced to
coagulate pollutants, which are then mechanically
separated from the water. After treatment,
the water is tested for contaminants and discharged
into the Greater Peoria Sanitary District
system.
The
heavy solids are mixed with coagulated material
removed from the water. Water is separated
and returned to the batch tanks. The heavy
solids are disposed of in our on-site landfill.
The
tramp oils on top are moved to a storage tank
where they are eventually solidified. Then
they are either deposited in the on-site landfill
or used as a treatment aid in our chemical
stabilization facility.

Sample
Testing and Verification
Discharge
water left over from our treatment process
is sampled and analyzed for a list of 8 metals.
Once every quarter we also sample and test
for total toxic organics at CFR 122.
The
Greater Peoria Sanitary District periodically
splits samples to conduct its own analyses
and verify PDC’s reported results. They
also conduct a full permit inspection at least
once per year.
