  • What factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
  • Why is anionic polyacrylamide chosen?
  • Anionic polyacrylamide is chosen because the intramolecular electrostatic repulsion between polymer segments forces the polymer chains to adopt a more extended conformation, increasing the efficiency of bridging flocculation.
  • Which cationic water soluble polymer is best flocculant for kaolin suspension?
  • Five cationic water-soluble polymers with different molecular weights and charge densities were obtained and then applied as flocculant for kaolin suspension. It was found that the best flocculation properties showed polymer with highest charge density and molecular weight.
  • Which cationic polymers are used as flocculants for silica aggregates?
  • An example is work by Zhou and Framks [ 31 ], where three cationic polymers (homopolymer of diallyldimehylammonium chloride and its two copolymers with acrylamide) of different molecular weights (1.1–3.0 × 10 5 g/mol) and charge density (CD) (10%, 40%, and 100%) were used as flocculants for silica aggregates.
