Sediment P inactivation is more cost effective that watershed BMPs on a cost per pound removal • Alum can be effective for 15 to 30+ years if dosed correctly • Controlling external P loads is important, but alum treatments can be effective even when watershed loads are moderately high • Alum is effective in shallow lakes and can support ...
Sediments settle to the bottom of the basin, and the effluent is strained from the top. These basins have inlet and outlet valves for flow control, and the bottom floor slopes to a hopper (pit) for the sludge collection. Sedimentation basins are classified as primary and final sedimentation basins, according to …

The effect of adding alum water treatment residues (WTR) on the methanogenic activity in the digestion of primary domestic wastewater sludge was evaluated through laboratory experiments in sedimentation columns, using total suspended solids (TSS) concentrations from 0.37 to 1.23 g/L. The addition of WTR to primary clarifiers can benefit its effluent water quality in terms of colour, turbidity ...
