A jar test reveals that the optimum alum coagulant dose is 50 mg/L at a pH of 8.1 and a temperature of 73 F. How many pounds per day of 49% alum are required for the whole plant? Total flow is 36 MGD with four parallel treatment plants, each designed for 12 MGD. Could use some guidance on setting up the equations.
As an operator of a wastewater treatment facility, you have learned that your plant runs well at an SRT (based on MLVSS (X) in the aeration basin) of 12 days. If today’s MLVSS (X) concentration is 2,700 mg/L and the RAS (Xr) concentration is 5,500 mg/L, how many L of sludge should you waste from the secondary clarifier today? Other design conditions: Average influent flow = 12,000 m3/d Influent soluble BOD = 150 mg/L Required effluent TSS = 30 mg/L Aeration tank Volume = 1,000 m3
