  • What is the degradation rate of polyacrylamide in soil & water?
  • Polyacrylamide degradation in soil and water PAM degradation rates in soil are estimated to be approximately 10% year −1 ( Barvenik, 1994 ). Degradation of the acryamide monomer (AMD) is fairly rapid ( Kay-Shoemake et al., 1998a, Shanker et al., 1990, Lande et al., 1979 ).
  • 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.
  • Is polyacrylamide effective for erosion control and water quality protection?
  • Since the early 1990s use of polyacrylamide (PAM) has been shown to be an effective strategy for erosion control and water quality protection ( Lentz and Sojka, 1994 ).
  • What is high molecular weight polyacrylamide (PAM)?
  • Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
