  • What is polyacrylamide (PAM)?
  • Polyacrylamide (PAM) possesses unique characteristics, including high water solubility, elevated viscosity and effective flocculation capabilities. These properties make it valuable in various sectors like agriculture, wastewater treatment, enhanced oil recovery, and mineral processing industries, contributing to a continually expanding market.
  • What are the different types of polyacrylamide?
  • Polyacrylamides can be classified into nonionic, anionic, and cationic ones [4, 5]. Each of these types due to their properties is used in many industries, mainly in water treatment, mineral processing, or soil conditioning . Application areas of abovementioned polyacrylamide types depend on the specific function of the polymer needed.
  • Can polyacrylamide contribute to residual polymer formation?
  • Common methods for treating PAM are membrane filtration 25, thermal distillation 24, oxidation treatment 26, and biological treatments 27. However, addressing the challenge posed by PAM remains a pressing issue within the industry. Fig. 1: Polyacrylamide and its fragments may contribute to residual polymer formation.
  • What is polyacrylamide used for?
  • One of the largest uses for polyacrylamide is to flocculate solids in a liquid. This process applies to water treatment, and processes like paper making and screen printing. Polyacrylamide can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.
