  • Where is Pam used in water treatment & sludge dewatering?
  • PAM used as a flocculant in water treatment or sludge dewatering is disposed in high-solid biogas digestors or landfills. 94 Although PAM is typically considered to be relatively recalcitrant to organic decomposition, 95 it can be degraded during anaerobic digestion.
  • What flocculants are used in water treatment?
  • Aluminium-based Flocculants: Aluminium sulphate (alum) is the most common aluminium-based flocculant used in water treatment. Its effectiveness is attributed to its ability to neutralise the electrical charges on colloidal particles, promoting their aggregation and subsequent sedimentation.
  • 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.
  • Is cationic Pam effective in flocculation?
  • The success of anionic and cationic PAM in flocculation can be related to particle charges that allow for particle flocculation with polymers. Non-ionic PAM was shown to be ineffective at flocculating tailing particles. The ionicity of the polymer appears to be highly relevant here, based on the results.
