  • Can hydrolyzed polyacrylamide be biodegraded?
  • Partially hydrolyzed polyacrylamide (HPAM) in production water after polymer flooding in oil filed causes environmental problems, such as increases the difficulty in oil–water separation, degrades naturally to produce toxic acrylamide and endanger local ecosystem. Biodegradation of HPAM may be an efficient way to solve these problems.
  • Does partially hydrolyzed polyacrylamide (HPAM) cause problems in production water?
  • However, partially hydrolyzed polyacrylamide (HPAM) present in production water causes some problems. For example, after polymer flooding, HPAM will remain in the produced water generated by oilfields, increasing the difficulty in oil–water separation.
  • Can hydrolyzed polyacrylamide improve oil recovery?
  • Introduction Water-soluble, anionic polyacrylamides have recently been widely used to enhance oil recovery in the east oilfields of China. However, partially hydrolyzed polyacrylamide (HPAM) present in production water causes some problems.
  • Is polyacrylamide biodegradable?
  • Study on HPAM biodegradation is not often seen in previous work, but polyacrylamide (PAM) biodegradation have been studied for a long period. However these studies provided seemingly contradictory results. Suzuki et al. observed that PAM was only slightly biodegradable under aerobic conditions.
