Please Solve this question. 4. An activated sludge plug flow reactor (PFR) is designed to treat domestic wastewater fororganic matter removal only. The following design parameters are given:mgMLVSSmgBOD,Y = 0.60K,= 100 mgBOD;/L, k= 0.10 d, um =0.7 d', S.= 250mgBOD5/L, S =10 mgBOD5/L,X=2000 mg MLVSS/L, , Q. = 75000 m/d, SVI = 90 ml/g,A. What is the sludge age 0, of this PFR?B. What is the volume of the PFR?C. What is the sludge wasting rate (Qw) in m/d needed to have an effluent suspended solidsconcentration (X.) of 30 mg/l in the treated wastewater coming out of the finalsedimentation tank?

Let us first find volume of the plug flow reactor: B. We know that: FM=1Y=Q0×S0V×XV=Q0×S0×YX Given…
