  • 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).
  • How does flocculation improve water quality in water supply plants?
  • Flocculation is a common method to improve filtration efficiency and purify water quality in water supply plants where the commonly used flocculant is cationic polyacrylamide (CPAM) (Vandamme et al. 2010; Teh et al. 2016). For sludge dewatering, CPAM shows superior conditioning performance and obtained more and more attention.
  • How much PAM based flocculants are consumed in France?
  • In France, for instance, the consumption of PAM-based flocculants is about 15 kt year −1. In particular, the aggregate production uses about 900 t year −1 of PAM-based flocculants (i.e., 6 % of the total consumption) as clarification aid (UNPG 2013).
