What is partially hydrolyzed polyacrylamide (HPAM)?

Partially hydrolyzed polyacrylamide (HPAM) is one of the most popular polymer used owing to strong thickening effect and good solubility ( Gao, 2013; Samanta et al., 2013 ). It was reported the content of HPAM in the produced wastewater ranged in 200–630 mg/L ( Li et al., 2021).

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.

How is partially hydrolyzed polyacrylamide wastewater treated?

Yongrui, P., et al. Treatment of partially hydrolyzed polyacrylamide wastewater by combined Fenton oxidation and anaerobic biological processes. Chem. Eng. J. 273, 1–6 (2015).

What is biodegradation of partially hydrolyzed polyacrylamide?

Biodegradation of partially hydrolyzed polyacrylamide by bacteria isolated from production water after polymer flooding in an oil field Critical perspective on advanced treatment processes for water and wastewater: AOPs, ARPs, and AORPs

What is Pam used for in water treatment?

PAM is also widely used as a flocculant in drinking water treatment (at concentrations <1 mg/L). 37 PAM can create bridges between destabilized particles, forming micron-size aggregates with good settling properties. 38 Cationic, nonionic, and anionic PAM have all been studied for flocculation.

What is thermal stability of water soluble polyacrylamide (PAM) and partially hydrolyzed polymers?

Thermal stability of water-soluble polyacrylamide (PAM) and partially hydrolyzed polyacrylamide (HPAM) polymers under various solution conditions have been studied utilizing Quantum Mechanics Density Functional Theory (DFT) computational modeling method.
