  • 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 are the product types for polyacrylamides?
  • The product types for polyacrylamides are solutions, liquids (emulsion or dispersion), and dry powders. The forms each have their own set of advantages and disadvantages as will be discussed in the following. 34.2.5.1. Aqueous solution polyacrylamides
  • 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 ].
  • What are the application areas of polyacrylamide?
  • Several of the application areas are discussed briefly in the following. Very high-molecular-weight polyacrylamides (both anionic and cationic) are used extensively in the area of hydraulic fracturing or stimulation for the increased production of natural gas, shale gas, tight gas, tight oil, and coal seam gas.
