Polyacrylamide and biopolymer effects on flocculation

Unlike PAM (polyacrylamide), biopolymer is made from a renewable resource. • The biopolymer was a less effective flocculating and soil stabilizing agent than PAM. • Biopolymer more effectively controlled seepage loss than PAM (at 500 mg/L AI). • Biopolymer may be an alternative to PAM for controlling seepage but not erosion.

Polyacrylamide and Chitosan Biopolymer for Flocculation

Recent studies have shown that turbidity in construction site runoff can be greatly reduced by chemical turbidity control. This study evaluated the performance of chitosan-based biopolymer (dual polymer system, DPS) vs. anionic polyacrylamide (PAM) for turbidity reduction and characteristics of flocculated sediments using two soils from North Carolina, USA.
