Secondary Clarifier

 An activated sludge plant has a design flow (average daily flow) of 11 MGD. Return sludge ratio R = 0.35.  Determine the dimensions of final settling tanks.  Check weir overflow rate. 

The design parameters:

number of tank = 4.      

Use circular tanks.  

MLSS = 3000 mg/L  

VSS/TSS = 0.80   

overflow rate = 1000 gpd/ft2,

detention time = 2  hr

weir overflow rate = 10,000 – 15,000 gpd/ft       

solid loading rate (lb/d/ft2) = 50 lb/d/ft2
