ground and returned to the sewage. Grit is removed by mechanical
scrapers to a sump pit. It is then pumped through a cast iron pipeline
to a lagoon where the grit settles out. The water is returned to the
plant for treatment.
Four three-speed automatic float controlled sewage pumps and one 10 MGD
gas driven engine raw sewage pumps with variable speed flow control
provide 70 MGD total plant pump capacity. Four pumps are operated by
125 HP electric motors. The gas engine will operate during pm~er failures.
These pumps lift the se\.,;rage thirty-two feet from the wet well to the raw
sewage trough. The trough has a hydraulic capacity of 60 MGD.
The primary tanks have a total capacity of 2,210,000 gallons or have
the capability to provide. treatment for 60 NGD. Rotary scum troughs
are lnstalled on all primary tanks. Ra';v sludge is removed by mech3nical
scrapers and f1mvs by gravity and manual controlled air lifts to a
sludge pit. It is then pumped to the primary digesters along with the
scum.
There are five tH'o-bay aeration tanks. The capaci ty of each bay is
1,050,000 gallons, making a total capacity of 10,500,000 gallons or
rated treatment capacity of 32 HGD with 30 percent of return sludge.
Three of the tanks are supplied by air passed through diffuser plates.
A fourth tank is 'supplied by air through ceramic diffuser tubes on
swing type headers, and the fifth tank is equipped with saran precision
diffuser tubes on s\ving type headers. The waste activated sludge
flows by gravity to the wet well.
