  • Should polyacrylamides be used in drinking water?
  • For health concerns, the use of polyacrylamides in drinking water has been subjected to closer evaluation during the last decade. Currently, dosage standards are indirectly based on the maximum concentration of acrylamide that would result from using a commercial formulation of known acrylamide content.
  • What is a polyacrylamide soluble polymer?
  • Polyacrylamide: This is a water-soluble polymer formed from acrylamide (a compound with a molecular formula C 3 H 5 NO) subunits. PAMs is most often used to increase the viscosity of water (creating a thicker solution) or to encourage the flocculation of particles present in water.
  • What is polyacrylamide used for?
  • Polyacrylamides, particularly polyelectrolytes, are widely used for water treatment as flocculants/coagulants and in tertiary oil recovery, as well as in various other applications such as sewer grouts.
  • Does biological filtration improve polyacrylamide biodegradation?
  • Freedman, D. E. et al. Biologically active filtration for fracturing flowback and produced water treatment. J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
