  • 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.
  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
  • How effective is polymer-assisted flocculation?
  • Most recent studies on polymer-assisted flocculation have reported exponentially decreasing settling profiles, indicating a high flocculant effectiveness. The slope of the initial linear part of the settling profile is called the initial settling rate (ISR), which determines the initial recovery of clean water from a suspension.
  • How effective is flocculant based on emulsion polymerization?
  • As an example, Fig. 3 a displays the dairy effluent and effluent condition at a dose of 53 mg/L (flocculant based on PAM tailored made with inverse emulsion polymerization); clearly, flocculant has been successful in removing “soft particles” from staying suspended in the water.
