A town has been directed to build an activated sludge plant that can meet an effluent standard of 13 mg/L BOD5. They have selected a completely mixed aeration tank. Calculate the volume of the aeration tank (V) (unit m3 ) using the following data:g/homework-help/questions-and- answers/determine-bod5-effluent-low -rate-trickling-filter-diameter-40- m-depth-15-m-flow-rate-2-200-q57182 303
