Performance of four polyelectrolytes as flocculation aids in the primary treatment of textile effluents
Samples of textile effluents were subjected to physico-chemical treatment using alum, Polyaluminium Chloride (PAC), and different anionic and cationic acrylamide copolymers. Except for alum, all chemicals were tested individually. Combinations of alum and PAC with different anionic and cationic polyelectrolytes were also tested. Results indicated the anionic polyelectrolyte to be the best polymer ...

Home water treatment by direct filtration with natural coagulant
ABSTRACTSeeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml−1, and fecal coliforms 280-500 MPN 100 ml−1), with seeds of S. potatorum or M. oleifera as ...
