effectiveness of natural polyelectrolytes in water treatment

Effectiveness of Natural Polyelectrolytes in Water Treatment

Synthetic polyelectrolytes are widely used in the United States because of their effectiveness as a coagulant or coagulant aid. Synthetic polyelectrolytes produce a lower volume of sludge compared with alum flocculation, and their effectiveness is not much affected by the pH level of water.

polyelectrolyte

Polyelectrolyte

Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions, making the polymers charged. Polyelectrolyte properties are thus similar to both electrolytes and polymers and are sometimes called polysalts. Like salts, their solutions are electrically conductive. Like polymers, their solutions are often viscous. Charged molecular chains, commonly present in soft matter systems, play a fu
