  • Is polyacrylamide a coagulant or flocculant?
  • In oil field applications, polyacrylamide is generally used as a rheology modifier. However, it can serve as a coagulant or flocculant in cleanup operations. In the recovery of oil, it can be used as a friction reducer in hydraulic stimulation, viscosifiers in tertiary oil recovery (chemical EOR), and drilling fluid viscosity modifier.
  • Is polyacrylamide a coagulant or a dispersant?
  • This is very much system-dependent. Most solution polyacrylamides fall into the category of coagulants, dispersants, fixatives, and paper strength resins due to the limits of the chemistry, desired active polymer content, desired charge, molecular weights, and shelf-life.

  • What is polyacrylamide (PAM) used for?
  • npj Clean Water 1, Article number: 17 ( 2018 ) Cite this article High molecular weight (10 6 –3 × 10 7 Da) polyacrylamide (PAM) is commonly used as a flocculant in water and wastewater treatment, as a soil conditioner, and as a viscosity modifier and friction reducer in both enhanced oil recovery and high volume hydraulic fracturing.
