A conventional activated sludge process is used to treat wastewater with a flow rate of 2000 m³/d and BOD concentration of 400 mg/L. The aeration tank is operated at an MLSS concentration of 2500 mg TSS/L, and HRT of 6 h. The sludge is wasted at 50 m³/d with SS concentration of 10,000 mg/L. BOD and VSS concentrations in effluent are 25 mg/L and 25 mg/L, respectively. Calculate the volume of aeration tank (m³), SRT (day), volumetric loading rate (kg BOD/m³-d), and food to microorganism ratio (mg BOD/mg VSS-d) for the process.
