polymer based flocculants review of water purification
in detail, the authors of ref [147] created anionic polymer flocculants (co- and terpolymers) that they used to treat dairy-effluent wastewater via flocculation. the results showed that polyelectrolytes with higher anionic contents performed better in the treatment process and that chemical modification increased hydrophobicity, especially when
polyelectrolyte polymers—types, forms, and function,the water obtained for the dewatering process can be discharged or recycled back into the process stream, thus reducing the demand for fresh water. anionic, cationic, and nonionic polyacrylamide are used as coagulants and flocculants for the solid-liquid separations and enrichment of various minerals depending on the situation or application.
types of polyelectrolytes used as flocculation agents
cationic, anionic, and nonionic polyelectrolyte are available for use as flocculants, and all three are extensively used in wastewater treatment [2,9, [19][21].
