- 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 is high molecular weight polyacrylamide (PAM)?
- Provided by the Springer Nature SharedIt content-sharing initiative High molecular weight (106–3 × 107 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.
- Is Pam a soil conditioner?
- PAM is currently used as a soil conditioner on ~800,000 ha 33 of irrigation land in the U.S., corresponding to 900–18,000 tons of PAM per year. PAM binds with soil particles through electrostatic interactions forming aggregates that prevent irrigation-induced erosion and increase the hydraulic conductivity of the soil.
- Can high molecular weight Pam be used for degradation?
- This paper provides a short review of current applications of high molecular weight PAM, including the potential for PAM degradation by chemical, mechanical, thermal, photolytic, and biological processes.
