Compute the hydraulic detention time (in hours) of an aeration tank.
QUESTION 4
If the SRT of a secondary reactor (aeration tank) is 5 days and the cell biomass concentration (known as MLVSS: Mixed liquor volatile suspended solids) is 2000 mg/L, compute the hydraulic detention time (in hours) of the aeration tank. (Given: soluble BOD5 in influent = 93.2 mg/L, soluble BOD5 in effluent = 10 mg/L, decay rate constant = 0.05 day-1, yield coefficient = 0.5)
