  • 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.
  • How to optimize wastewater treatment plants in urban China?
  • Undeveloped sewers, inefficient treatment facilities, etc. were responsible for low efficiency of WWTPs. The optimization of WWTP needs to start from the management of facilities and operation, establishment of supervision system. Wastewater treatment plants (WWTPs) in urban China generally face operational difficulties.
  • What coagulants are used in China's municipal sewage treatment plants?
  • In China’s municipal sewage treatment plants, inorganic polymeric coagulants such as polymeric aluminum chloride (PAC) and organic polymeric flocculants such as polyacrylamide (PAM) are generally added to thickened sludge for sludge conditioning prior to dewatering.
