  • How effective is polyacrylamide flocculation?
  • Of the many natural and synthetic polymers available today, polyacrylamide (PAM) and its derivatives are among the most important and extensively used flocculants. Separation by flocculation is effective and sufficient when the end objective is reduction in sludge volume and rapid separation of solids from liquids.
  • What is a polymer flocculant?
  • Among the synthetic polymer flocculants, the most important is water-soluble polyacrylamide (PAM)—a non-ionic, amorphous polymer which can be modified to ionic form in the copolymerization process [ 8, 9, 10 ]. The acrylamide monomer can be used for grafting or crosslinking of other type of polymers.
  • Can polyacrylamide flocculants be used in mineral processing?
  • The use of polyacrylamide flocculants in mineral processing has been reviewed in detail (Moody, 1992). In addition to flocculation, polymers have also been used as filtration and dewatering aids with the aim of increasing the filtration rate as well as reducing residual filter cake moisture content.
  • 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.
