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.

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 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.

What is polyacrylamide used for?

Polyacrylamide (PAM) is a high molecular weight polymer that comes in three types: cationic, anionic, and non-ionic. Its molecular chain contains a large number of covalent bonds, giving it excellent adsorption properties. As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields.

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 anionic polyacrylamide used for?

Anionic polyacrylamide can pick up positively charged particles (clay, sand), much like a magnet picks up nails and other metal objects. APAM can be widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic industry.
