  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 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.
  • What is a hydrolyzed Pam?
  • Furthermore, the hydrolyzed form of PAM (HPAMs), are copolymer made of AM and AA. Non-ionic (NPAMs), cationic (CPAMs) and anionic PAM (APAMs) can be utilized as flocculants or coagulants for wastewater treatment in various industries.
  • How is partially hydrolyzed polyacrylamide wastewater treated?
  • Yongrui, P., et al. Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes. Chem. Eng. J. 273, 1–6 (2015).
  • What is hydrolyzed polyacrylamide (HPAM)?
  • Hydrolyzed polyacrylamide (HPAM), a derivative resulting from the hydrolysis of PAM, demonstrates significant thickening capabilities in freshwater and at relatively lower temperatures (<75 °C) due to strong intra- and inter-chain electrostatic repulsion of carboxylate groups 14.
