  • Acrylamide Uses and Production

    2018-5-29 · Polyacrylamide can be manufactured as cationic, non-ionic, or anionic polymer. Both cationic and anionic polyacrylamides are produced by the process of copolymerisation of acrylamide. Cationic polyacrylamides are useful for flocculation of sewage sludge and various industrial wastes, as well as retention aids in the paper industry (Barvenik, 1994).

    Cationic polyelectrolytes are now considered as the most effective flocculants for the recovery of microalgae (Uduman et al., 2010). Recently found cationic polyelectrolytes are more effective at flocculating freshwater microalgae than metal salts, achieving a high biomass concentration (concentration factor up to 35 times) at lower dosage rates of 2–25 mg L − 1 ( Granados et al., 2012 ).
