  • Is grafted flocculant effective compared to commercial cationic polyacrylamide?
  • The grafted flocculant was found to be effective compared to commercial cationic polyacrylamide.
  • Does anionic polyacrylamide improve coagulation-flocculation process?
  • Aguilar, M. I. et al. Improvement of coagulation-flocculation process using anionic polyacrylamide as coagulant aid. Chemosphere 58, 47–56 (2005). Muller, G., Fenyo, J. C. & Selegny, E. High molecular weight hydrolyzed polyacrylamides.
  • What are flocculants made of?
  • In most cases, flocculants are polymers composed of polyacrylamide (PAM) (Taylor et al. 2002). PAM is a polymer with high molecular weight, synthetized from acrylamide (AMD) and acrylic acid/acrylate (AA) (Scott et al. 1996; Caulfield et al. 2002).
  • 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
