ABSTRACT
Waste Activated Sludge (WAS) pumping rate calculations are calculations that involve mglL and flow. Therefore the equation used in these calculations is:
(mglL) (MGD) (8.34) = lbs/day I flow lbs/gal In WAS pumping rate calculations, the "WAS SS" refers to the suspended solids content of the Waste Activated Sludge being pumped away, and "MGD flow" refers to the WAS pumping rate of the sludge being wasted.
