  • 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.
  • Why is polyacrylamide a problem in water treatment?
  • At the same time, a large amount of sewage containing polyacrylamide (PAM) was produced. This kind of sewage has a high degree of emulsification, high viscosity and serious environmental hazards. It is a difficult problem for water treatment in recent years [ 1, 2 ].
  • What is polyacrylamide used for?
  • Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.
  • Can non-thermal plasma be used to treat polyacrylamide (PAM) wastewater?
  • In this work, non-thermal plasma has been applied to treat polyacrylamide (PAM) wastewater. We have investigated the influence of the rule of PAM wastewater initial pH, solution concentration and discharge time, discharge voltage on chemical oxygen demand (COD) degradation rate.
