  • How efficient is a Pam wastewater treatment plant?
  • Using this technique, a PAM wastewater treatment plant with a processing capacity of 600 m 3 ·d −1 was implemented and has been stably operated for nearly 18 months. Compared to the pervious process, the HRT decreased 50% and the COD, NH 4 -N and T-N removal efficiency increased to 93%, 92% and 67–80%, respectively.
  • Can a multistage biofilm reactor treat Pam production wastewater?
  • In this study, a multistage biofilm reactor was able to treat PAM production wastewater. The independent chambers formed a unique bacterial community that could improve the reactor performance and tolerate the substrate shock loads.
  • 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.
  • What are the environmental challenges posed by Pam?
  • These applications of PAM can result in significant environmental challenges, both in water management and in contamination of local water supplies after accidental spills.
