Chemtex Speciality Limited manufactures Polyelectrolyte which is a strong polymerbased coagulant which is specifically designed for partial or complete settling of organics water soluble matters and suspended solids in the effluent or waste water through electro neutralization and bridging absorption Bridging absorption occurs when long chain polymers get absorbed on the particles in a pattern such that it forms loops and tails extending some way in the solution At this stage particles are said to be restabilized Absorbed amount must be optimum otherwise enough bridging contacts couldnt form This consideration results in the necessity for an optimum dosage of the product for formation of bridging flocculation
