  • 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.
  • Are LCST polymers soluble?
  • LCST polymers are soluble at low temperatures but become insoluble at higher temperatures. After the discovery of the LCST behavior of poly ( N- isopropylacrylamide) (PNIPAm) in aqueous solutions by Heskins et al. in 1968, the molecular design and applications of LCST polymers have invoked long-lasting attention from researchers.

  • Is polyacrylamide used in water treatment manufacturers of South Africa?
  • polyacrylamide use in water treatment manufacturers of South Africa. SNF is the world’s largest producer of polyacrylamide (PAM), a water-soluble polymer specifically designed to improve the quality and conservation of water. PAM has a broad variety of industrial and commercial uses as a flocculant, which.,Our Products | OsheChem WATER TREATMENT.
  • 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 ].
