Question: A rectangular primary sedimentation basin is to be designed for an activated sludge treatment plant serving a municipality. The regulatory agency criteria for primary sedimentation basins used for activated sludge system are as follows: peak overflow rate (S) = 80 m3/d-m2, average overflow rate (S) = 40 m3/d-m2, peak solids loading = 50 kg/d-m2, peak weir loading = 372 m3/m-d. The average flow to the basin is 12 000 m3/d. Calculate the tank surface area in m2. Calculate the peak flow rate in m3/d. Calculate the total suspended solids concentration in the incoming flow to the basin (mg/L) Calculate the total weir length (m)
