  • Can cationic polyacrylamide be used in oilfield wastewater treatment?
  • Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
  • What type of polyacrylamide is used in oil industry?
  • The polyacrylamide use can be anionic, cationic, or nonionic with various ratios of the comonomers used in the case of the anionic and cationic polymers. The anionic polyacrylamides in the oil field industry are designated by the generic name of partially hydrolyzed polyacrylamide (PHPA), although they are in actuality copolymers .
  • How much cationic polyacrylamide should be used for sludge treatment?
  • For sludge treatments, consumption of a cationic polyacrylamide of 5.4 g·kg −1 of total solids is found to be the best economical solution . Several studies were made, following life cycle analyses, to evaluate energy consumption of wastewater treatment (e.g., Tillman et al. , Hospido et al. and Wenzel et al. ).
  • What is an anionic polyacrylamide used for?
  • There is a wide range of uses for anionic polyacrylamides and these include wastewater treatments aids, retention aids, and strength agents in papermaking, hydraulic stimulation, and enhanced oil recovery in oil field applications, mineral processing, and as soil conditioners in agricultural uses.
