The increasing scarcity of quality drinking water along with rapid population increase in urban areas gives reason for concern as well as the need for sustainable water management practices. Wastewater and industrial effluent treatment require removal of suspended solids for purification and re-usage. The removal can be accomplished by flocculation and coagulation with cationic polymers made from acrylamide and cationic methacrylate monomers, such as VISIOMER® TMAEMC and MAPTAC. The charge intensity of the polyelectrolyte can be customized by tweaking the amount of quaternized monomers incorporated into the polymer.
