Coagulation and Flocculation - Wastewater Treatment
Coagulation and Flocculation - Wastewater Treatment

In environmental engineering, particularly a wastewater treatment field, flocculation refers specifically to, destabilization, of colloidal particles by forming aggregates of colloids with added water-soluble polymers (polymer bridges); coagulation is caused by destabilization of colloids through compression of electrical double layers of the particles.

In wastewater treatment, polyacrylamide-based, flo,cc,ulants, are commonly used. Because they can contain potentially toxic acrylamide residues, flocculants based on natural biopolymers are preferred over synthetic polymers. An effective biopolymer flocculant for harvesting microalgae is chitosan, which is prepared by deacetylation of chitin.
