  • Is polyacrylamide flocculant biodegradable under anaerobic conditions?
  • The present study is aimed at investigating biodegradability and toxicity of the polyacrylamide flocculant under anaerobic conditions and at testing the possibility of the application of PAM-enforced flocculation for stabilization of anaerobic digestion after excessive VFA accumulation. 2. Materials and Methods 2.1. Substrate and Inoculum
  • Can cationic polyacrylamide flocculant be used for methanogenesis restoration?
  • Existing methods of stabilization of this process are mostly expensive and labor-intensive, often requiring removal of a considerable portion of acidified biomass from the bioreactor. We propose a method for methanogenesis restoration in such soured reactors by the addition of a cationic polyacrylamide flocculant (PAM) at 20 mg/g total solids.
  • Which polyacrylamide cationic flocculant is used for SS thickening?
  • Polyacrylamide flocculants are most often used in wastewater treatment and utilization of sewage sludge to improve the separation of the solid and liquid phases [ 13, 14, 15 ]. In our earlier experiments, different concentrations of the polyacrylamide cationic flocculant Praestol 650 (PAM) were used for SS thickening before batch-mode AD.
  • Can cationic polyacrylamide flocculants be used to treat oily water?
