  • Is cationic polyacrylamide emulsion a flocculant for paper mill wastewater treatment?
  • " Cationic polyacrylamide emulsion with ultra-high concentration as a flocculant for paper mill wastewater treatment ," BioRes. 15 (2), 3173-3189. Cationic polyacrylamide emulsions prepared with ultra-high concentration (CPAME-uhc) have the advantages of fast dissolution, convenient operation, and low transportation cost.
  • What is cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is one of the most frequently used flocculants with high intrinsic viscosity and charge density. This flocculant is a water-soluble acrylamide-based polymer having cationic quaternary ammonium groups .
  • How cationic polyacrylamide (PAMC) is prepared?
  • Flocculation and mechanism was discussed based on zeta potential and pH analysis. A novel cationic polyacrylamide (PAMC) with various cationic monomer contents were prepared by copolymerizing acrylamide (AM) and methacryloxyethyl trimethyl ammonium chloride aqueous solution (DMC) through low-pressure ultraviolet (UV) initiation.
  • Can cationic polymer flocculants be developed by photo-polymerization?
  • In this study, we utilized recent developments in the photo-polymerization technique to develop two cationic polymer flocculants by polymerizing two types of monomers for harvesting Chlorella vulgaris ( C. vulgaris) and Porphyridium purpureum ( P. purpureum ), which are freshwater and marine microalgae species, respectively.
