A municipality gas a completely mixed activated sludge process (with no recycle)

A municipality gas a completely mixed activated sludge process (with no recycle) that meets an effluent standard of 20mg/L BOD; (soluble + particulate) and 25mg/L TSS. For their waste, assume that the BODs of the TSS is 59% of the TSS concentration. Utilize the following information to complete this problem. Q = 10000 m/day BODs/L Ks = 100 mg ke = 0.05 /day Yk = 2.5 / day a. Calculate the allowable soluble BODs (Se) in the effluent in mg/L b. Calculate the SRT in days c. Calculate the HRT in days d. Calculate the volume (m) of the CSTR
