The City of Activia has an activated sludge WWTP that treats 21 million L of wastewater per day. The effluent from the WWTP flows out at 20 million L/day. The recycle flow rate is 23 million L/ day. The influent and effluent BOD5 are 380 mg/L and 18 mg/L, respectively. The biomass (MLVSS) concentrations in the waste sludge and clarifier effluent are 4,400 mg/L and 15 mg/L, respectively. The solids retention time is 5 days. A process flow schematic is shown below. Qi, Si, Xi Qas Sa, Xa Qe, Se, Xe Qr. Sr. Xr What is the total biomass discharge rate (in kg/day) Qw. Sw. Xw
