Polyelectrolytes are regarded as polymer chains with an electrolyte group on every repeat unit. When dissolved in a polar solvent, these polymers are charged due to dissociation of small counter ions that leave behind a charged macro ion. Polyelectrolytes include biologically important molecules such as polypeptides and DNA. These are referred to as polymers that are generally used for water purification. These are highly noted for their beneficiary nature of handling problems of slow settling of flocs in water at low temperature, treating soft colored water where they increase toughness of the flocs and enhance its settlement ability. Polyelectrolytes are formulated in a way so as to be used as coagulants and flocculants as well as a sludge dewatering agent in the waste water treatment plants. P olyelectrolyte , thereby, plays an indispensable part in the sludge conditioner formulation. Generally flocculation occurs owing to charges present on the particles. Generally, Pol...

Polyelectrolyte is a long chain of repeating monomers (electrolyte). They are available in white powder . Polyelectrolytes when dissolved in water get charged due to the presence of the electrolyte group, and hence they help in neutralization of the suspended colloids or the small flocs produced after coagulation. The high molecular weight of polyelectrolytes aid in fast settling of the flocs.    There are 4 types of polyelectrolyte used in water treatment industries. ·          Anionic Polyelectrolyte –   Negatively charged. ·          Cationic Polyelectrolyte – Positively charged. ·          Nonionic Polyelectrolyte – No charge. ·          Amphoteric Polyelectrolyte– Contains both positively and negatively charged groups. Dosage : The amount of chemical required to perform depends on ...
