  • 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.
  • What are some examples of anionic polymer flocculants?
  • Representative anionic polymer flocculants are as follows: (1) partially hydrolyzed polyacrylamides, (2) copolymers of acrylamide and acryl acid soda, (3) copolymers of acrylamide and acrylamide-2-methyl-propan sulfonic soda (AMPS), and (4) poly (sodium acrylate).
  • 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.
  • Which polymer is used to flocculate coal mine wastewater?
  • Sodium polyacrylate was used as the template and improved the reactivity ratio of DMD, which increased the DMD segments in polymer chains. TPDA was used to flocculate coal mine wastewater, showing good performance and producing large, stable, and compact aggregates. 63 Table 2 summarizes the recently developed synthetic polymer flocculants.
