  • Which flocculants are used in water treatment?
  • The flocculants include: low MW anionic PAM (aPAM1, CD < 5%, Veolia Water Technologies), high MW anionic PAM (aPAM2, CD < 5%, Kemira Water Solutions Canada Inc.), low MW cationic PAM (cPAM1, CD ≈ 7%, Kemira Water Solutions Canada Inc.), low MW cationic PAM (cPAM2, CD ≈ 20%, Kemira Water Solutions Canada Inc.).
  • Can polymer materials be used as water soluble flocculants?
  • Our review indicates that there has been a large body of literature in the recent years focusing on introducing new polymer materials as water soluble flocculants for a variety of applications including wastewater treatment, mineral processing, and oil sands tailings treatment.
  • How is an anionic polyacrylamide flocculant synthesized?
  • In this study, an anionic polyacrylamide flocculant was synthesized by ultrasonic initiated template copolymerization (USTP), using sodium allylsulfonate (SAS) and acrylamide (AM) as monomers, poly diallyl dimethyl ammonium chloride (polyDADMAC) as template, and 2,2′-azobis [2- (2-imidazolin-2-yl) propane] dihydrochloride (VA-044) as initiator.
  • What are flocculants used for?
  • Flocculants, usually composed of PAMs, are widely used in several industrial fields, particularly in minerals extraction, to enhance solid/liquid separation in water containing suspended matter. These polymers can contain residual monomer of acrylamide (AMD), which is known to be a toxic compound.
