  • What are cationic polymer flocculants?
  • Representative cationic polymer flocculants include (1) copolymers of acrylamide and acryloyloxyethyl trimethylammonium chloride, (2) poly (methacryloxyethyl trimethylammonium chloride), and (3) polyamidine. Their molecular weight ranges from several million to less than 20 million.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • Does polyacrylamide structure affect flocculation of bentonite clay?
  • Shaikh and coworkers studied the effect of polyacrylamide structure on the flocculation of bentonite clay. 208 Using turbidity as a powerful measure, they compared flocculations using cationic, anionic, and amphoteric polyacrylamides of varying molecular weights.
  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
