  • Can cationic polyacrylamides be used to purify industrial waste water?
  • The use of anionic, cationic as well as non-ionic polyacrylamides in purification of industrial waste waters have been reported ( Lee et al., 2014 ). In the papermaking industry, anionic and cationic polyacrylamides are used as aids for improving the retention of fillers, sizing agents and fine particles.
  • Is polyacrylamide a cationic or inorganic salt?
  • ABSTRACT Cationic polymers (e.g. polyacrylamide) having a high molecular weight require a much lower dose than inorganic metal salts (e.g. AlCl3, FeCl3, or Al2 (SO4)3) to produce dense compact flocs… Polyacrylamide (PAM) is generally employed in wastewater treatment processes such as sludge dewatering and therefore exists in the sludge.
  • Is polyacrylamide released during biodegradation under aerobic conditions?
  • In any case, no evidence has been found that free acrylamide monomers of polyacrylamide would be released during biodegradation under aerobic conditions, ruling out unzipping reactions of the polymer ( Caulfield et al., 2002 ). An aerobic reaction pathway, similar to α-oxidation of fatty acids, has been hypothesized for polyacrylamide.
  • Is polyacrylate more recalcitrant to biodegradation than amide?
  • The carbon backbone, polyacrylate, is more recalcitrant to biodegradation than the amide moieties. There are nevertheless reports on microbial growth with polyacrylamide and polyacrylate as the carbon sources.
