  • Is acrylamide a cationic flocculant?
  • The copolymer of acrylamide (AM) and DMC is used as an effective cationic flocculant in wastewater treatment. A series of copolymers of AM and DMC (PAMC) were synthesized using different approaches. In earlier studies, γ-ray irradiation with inverse emulsion polymerization was employed to copolymerize AM and DMC .
  • What type of polymer is a flocculant?
  • Most flocculants are acrylamide-based polymers and may be available in anionic, cationic, nonionic, or amphoteric forms 18. The copolymer adsorption on the surface of montmorillonite particles generally depends on the functional group of monomers and charge distribution 19, 20, 21.
  • Why do polymer flocculants fail in water based drilling fluid?
  • Some polymer flocculants exhibit notable sensitivity to the salinity of the fluid 12, 13. Various water soluble polymers have been used in the water-based drilling fluid to prevent fluid loss. The high temperature causes the failure of drilling fluid treatment agent 14.
  • Can acrylamide based flocculants be used in oil sands extraction?
  • A representative example comes from the effluents (tailings) of oil sands extraction process that contain high solids organic-contaminated fine clays, where the use of conventional acrylamide-based flocculants does not meet the dewatering criteria needed by this industry. 3
