  • Do cationic and anionic Pam improve particle flocculation characteristics?
  • The results revealed that when the ionic strength and MW were low, anionic flocculation characteristics improved, but cationic flocculants performed better when the cationic strength and MW were high. The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers.
  • 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).
  • Is Pac-am-DMC a novel organic-inorganic hybrid flocculant?
  • The poly aluminium chloride-acrylamide-methacryloxyethyltrimethyl ammonium chloride (PAC-AM-DMC) flocculant was found to be a novel organic-inorganic hybrid flocculant in this study due to having a good yield at low applied dosage; therefore, leaving less chemical residue in waters after flocculation.
  • What is a Common anionic Pam?
  • Common anionic PAMs are usually produced by copolymerization of AMD and AA or one of its salts (see Fig. 1). Their molecular weights vary between 3.10 6 and 2.10 7 Da. The most polyvalent anionic PAM contains around 30 % of acrylate (mol). Synthesis pathway of anionic PAMs
