  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
  • What is a non hydrolyzed polyacrylamide (PAM)?
  • Non-hydrolyzed polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) are frequently used in many industrial applications including waste water treatment processes (Guezennec et al. 2015 ), soil conditioning and erosion control (Levy and Warrington 2015 ), and oil and gas operations.
  • Are cationic polyacrylamide copolymers used for sludge dewatering?
  • Environmental Sciences Europe 30, Article number: 16 (2018) Cite this article Cationic polyacrylamide copolymers (PAMs) are used for sludge dewatering in municipal waste water treatment and might enter the environment by spreading of the sludge on agricultural land.
  • Can microbial communities biodegrade Pam & HPAM sludge?
  • Produced waters from hydraulic fracturing operations and waste water sludges are commonly exposed to polymers such as PAM or HPAM at relatively high temperatures (> 50 °C). Thus, we hypothesized that these environments harbour microbial communities able to biodegrade these polymers under thermophilic conditions.
