Why is polyacrylamide important in wastewater treatment?

The correct use of polyacrylamide will contribute to improving municipal wastewater treatment results, protecting water resources, and achieving sustainable development. In the wastewater treatment industry, polyacrylamide has become an indispensable agent.

What are the applications of polyacrylamide (PAM)?

As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields. Polyacrylamide is mainly used in the flocculation, sedimentation, and dewatering processes in municipal wastewater treatment.

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.

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 cationic polyacrylamide used for?

(2) Anionic polyacrylamide: Suitable for treating wastewater containing cationic suspended solids, such as mine wastewater and alkaline wastewater. It can bind with cationic suspended solids in the wastewater, forming flocs to promote solid-liquid separation.

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.
