  • 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 factors affect the flocculation effect of cationic polyacrylamide (CPAM)?
  • Cationic polyacrylamide (CPAM) is a commonly used flocculant for water treatment. Factors that affect the flocculation effect and can be controlled manually include the type and dosage of CPAM, wastewater pH, stirring time and settling time, and their reasonable setting is critical to the flocculation effect of CPAM.
  • Why is polyacrylamide used in water treatment and sludge dewatering?
  • Polyacrylamide and its copolymers are extensively employed in water treatment and sludge dewatering. The efficiency of flocculation is influenced by factors such as the type of flocculant used, its molecular weight, and its concentration in the water suspension.
  • Why are cationic surfactants used in polyacrylamide adsorption?
  • This is due to the addition of cationic surfactants in the suspension, as cationic surfactants can assist the polyacrylamide adsorption of suspended particles in wastewater through electrostatic action, whereby the more negatively charged suspended particles are in wastewater, the more pronounced is this auxiliary flocculation effect [ 36 ].
