  • 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 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.
  • 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).
  • Is flocculant a linear non-crosslinking polymer?
  • This flocculant is a linear non-crosslinking polymer. The hydroxyl groups on biopolymers can be oxidized to aldehyde groups. In addition, the aldehyde groups can be further transformed into other functional groups by modification.
