Reference no: EM13314164

An activated sludge plant is to be designed for a population of 4000 persons. The influent flow is 380 Lpcd and the influent BOD5 is 200 mg/L. Pertinent data are: Primary clarifier removes 33% of the influent BOD5, and the state regulatory agency allows a volumetric loading of 0.48 kg BOD5 /(m3.day). Determine the reactor basin volume.
