  • 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.
  • 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.).
  • Are polymer-based flocculants effective in treating wastewater from mining industries?
  • However, Sarkar et al., demonstrated the efficacy of naturally abundant polymer-based flocculants/adsorbents for treating wastewater from mining industries [ 102 ].
  • 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
