Unformatted text preview: 200 mg/l and a per capita waste flow generation of 100 gallons per capita day. a. Draw a diagram of the treatment train you propose. b. What is the organic loading to the conventional activated sludge unit (Kg-BODS/day. c. Assuming a peaking factor of three (3), size (volume) the activated sludge tank. d. Assuming a depth of 6 feet is the unit’s hydraulic retention time in bounds? e. What overflow rate would you use for the secondary clarifiers? f. How many would be appropriate from an operation perspective? g. Size the clarifier(s) assuming they are circular. h. Assuming you have two activated sludge units, could the plant operate with one down? Did you remember to apply a safety factor in your sizing under c)?...
