Flocculants Polyelectrolyte is used for solids removal, water clarifying, lime softening, sludge thickening, and solids dewatering. This is a branched or linear polymer that carries an ionic charge along its chain. As a result, it is classed as a cationic, anionic, or non-ionic polymer. It is a water-soluble organic polymer that is utilized as a principal coagulant or coagulant aids in the clarifying process. It uses physical or chemical forces to bind particles together and neutralize surface charges on cells.
