  • 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.
  • Why is polyacrylamide a water soluble nonionic flocculant?
  • Nonionic flocculants normally have high molecular weights, which helps them flocculate suspended particles through the bridging mechanism. Polyacrylamide is the most important water soluble nonionic flocculant because its mon-omer, acrylamide, is highly water soluble, cost-effective, and very reactive.
  • What are polysaccharide flocculants based on?
  • The polysaccharides flocculants based on starch, chitosan, cellulose, and their derivatives are listed in Table 1. Polysaccharide flocculants used in water and wastewater treatment.
  • Who bought polyacrylamide flocculant?
  • Commercial flocculant of polyacrylamide (PAM, MW of 2000–14,000 kDa) was bought from Aladdin Industrial Corporation (Shanghai, China). Anhydrous ethanol and acetone were supplied by Zhenqi Chemical Reagent Co., Ltd (Shanghai, China).
