Polyelectrolytes are water soluble polymers composed of a long polymer chain, combined with an ionic charge. Depending on the nature of the ionic charge, the polyelectrolyte can be classified as Cationic, Anionic or Non-Ionic. Polyelectrolytes are available as various grades on basis of molecular weights, charge densities, and hydrolysis values.
Polyelectrolytes are capable of promoting flocculation by neutralising the electric charges of suspending particles in the water and unstabilizing the particles. The particles are subsequently absorbed by the activated functional group in the polymer chain.
Polyelectrolytes find application in industrial waste water treatment, drinking water treatment, sewage treatment and various process industries like sugar, paper, mining, etc.
