Flocculants - an overview | ScienceDirect Topics

In wastewater treatment, polyacrylamide-based flocculants 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.
