CE3503 Expectations – Wastewater Treatment

A wastewater treatment plant will receive a flow of 35000 m3·d-1 (~10 MGD). Calculate the mass of sludge wasted each day (Qw·Xw, kg·d-1) for an activated sludge system operated at a solids retention time (SRT or (c) of 5 days. Assume an aeration tank volume of 1640 m3 and a MLSS concentration of 2000 mg·L-1. ................
