  • 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.
  • 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.
  • Can Pam be used as a coagulant aid in high-concentration wastewater treatment?
  • Charge neutralization and adsorption bridging of PAM played a significant role in the dual-coagulation. Therefore PAM can be used as an efficient coagulant aid for PAC to promote floc properties. Results of this study would be beneficial for the application of dual-coagulation in the high-concentration wastewater treatment.
  • Is polyacrylamide a good flocculant?
  • Polyacrylamide (PAM, − CH 2 CHCONH 2−) is a flocculant that is commonly used in the treatment of drinking water. By building bridges between destabilised particles, PAM could create micron-sized aggregates with good settling qualities. Cationic, nonionic and anionic PAM materials have been investigated for their flocculation capabilities.
