Polyacrylamide Use for Sediment Reduction in Construction Site Stormwater

Sedimentation basins are used to collect runoff from construction sites and reduce the amount of sediment transported to local water bodies. Chemical coagulants are used to increase sedimentation efficiency rates in a variety of water and wastewater treatment processes. Laboratory studies were conducted using anionic and cationic polyacrylamides as well as alum to evaluate efficiency on sediment pond performance. Tests of total suspended solids, total solids, and turbidity were conducted. Laboratory studies of various coagulants demonstrated the potential to reduce turbidity by an additional 25-35%. A protocol was developed for the selection of proper coagulants for field testing.
