Discharge Number 001, formerly 001 & 002, (manufacturing areas)
.750 MGD
This discharge consists of non -contact cooling water from
electro-coating process machines and related process equipment
plus small amounts of process wastes from the cleaning and
coating applications, air condition condensate, boiler blowdown,
and water dionization plant discharge from regeneration stream.
This discharge consists of Discharges 001 and 002 on the EPA
issued permit.
Discharge Number 003 (manufacturing areas).
This discharge consists of non -contact cooling water plus wash
water used to clean completed capacitors, and air condition
condensate.
Discharge Number 005 (etch house). .500 MGD
This discharge consists of non -contact cooling water from various
etching and cleaning operations -and contact rinse water. The
discharge consists of acids alkalies, sodium chloride (brime),
etched aluminum by-products, and cleaners. The majority of the
aluminum removed from the foil during the anodizing operations
is precipitated out and then vacuum filtered from the brine.
Brine is re -used and the aluminum precipitate is sold to another
company that converts it to alum.
Discharge Number 006 (sanitary flows plus cafeteria). .018MGD
The sanitary waste treatment facility is an 18,000 GPD plant
consisting of a bar screen Imhoff tank, dosing tank with dual
alternating siphons, dual sand filters, sludge drying beds with
return for bed effluent, a chlorination system and flow
measurement.
Discharge Number 007, formerly water plant filter backwash, (fire
pump test water only).
The fire pump is operated to assure that it will function
properly during emergencies. Water is merely withdrawn from the
river and then returned directly with no treatment.
Lagoon Holding System (no direct discharge).
Wastewater from the etching areas and coating areas are discharged
into a dual lagoon system at the rate of approx. 30 GPM. The
primary lagoon (upper) receives all waste deemed inappropriate for
direct discharges to the New River. No oils are put into the
lagoon by intent. Precipitates settle out and wastes tend to
equalize. During extremely wet weather, several siphons are used
to releave high water levels in the upper lagoon to a lower
lagoon. The wastewater either evaporates from the lagoons or
flows through the solids under them. When the lagoons become
full of solids, they have been drained, allowed to set up and
then stabilized or covered.
