  • 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).
  • Does a high Pam concentration affect flocculation?
  • Application of PAM concentrations higher than 20 g/kg TS is probably less efficient due to the inhibitory properties of the flocculant. Our experiments revealed that pH decrease caused by excessive VFA accumulation did not affect flocculation.
  • Does Pam degradation affect flocculant performance?
  • PAM-based flocculant degradation has been mainly studied for PAMs in aqueous solutions. The degradation of PAMs results in a reduction of the molecular weight of the polymer and can adversely affect the performance of such aqueous solutions in their commercial application as flocculants.
  • Are Pam flocculants toxic?
  • The potential environmental hazard does not concern the PAM itself, which is generally considered as not toxic (Andersen 2005), but the products of PAM degradation and the residual AMD contained in the flocculants due to incomplete polymerization process (Labahn et al. 2010; Young et al. 2007; Caulfield et al. 2002).
