  • What are polymer flocculants?
  • Polymer flocculants are water-soluble polymers which can form flocs from individual small particles in a suspension by adsorbing on particles and causing destabilization through bridging or charge neutralization. Polymer flocculants are high molecular weight polymers and have hydrogen-bonding groups and/or ionic groups in the molecule.
  • Is polyacrylamide a comonomer?
  • Polyacrylamide (PAM) is the basis for most commercial polymeric flocculants mentioned in the literature (anionic, cationic, or non-ionic); this polymer is also modifiable with combinations of comonomers.
  • 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.
