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.

What is a high molecular weight anionic polymer flocculant?

High molecular weight anionic polymer flocculant. Accepta 2047 is a superior quality anionic high molecular weight latex emulsion polyacrylamide co-polymer for effluent and wastewater treatment.

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).
