In the startup phase, it is proposed to use approximated 20 percent of the process volume by using only
the membrane and the Anoxic 1 c'hamber at a seven -foot working water level. water will enter the plant
through the 2-mm screen and then into the equalization basin. The equalization water level will be
lowered to a maximum working level of four -feet. Form equalization the water will be pumped to the
Anoxic -1-b-a'si-n. water will be first -treated -i-n the Anoxic -1 basln a,nd the'n flow -to the oxic environment of
the membrane tank. The internal recycle pump will pump water back from the anoxic I tank to the
membrane tank and returned to the Anoxic 1 tank. At a 400% recycle rate. Sludge will be wasted to the
sludge holding tank.
At 5,000 GPD the FM Ration will be .015 BOD or .027 COD. Though on the low end, we have operated at
this FM Ratio before with success. The operator will be instructed on watching the Transmembrane
pressure carefully and the engineers will watch carefully via the Scada system. If it looks to be a an
issue the operator will start feeding the system with micro C.
