Can anionic polyacrylamide be used in water treatment?

What's more, the authors discussed the application status of anionic polyacrylamide in water treatment. Based on these reviews, future research perspectives relating to its synthesis and application were proposed. This review summarizes the synthesis methods for anionic polyacrylamide.

What are the different types of anionic polyacrylamide synthesis technologies?

The paper lists six different kinds of anionic polyacrylamide synthesis technologies, including homopolymerization posthydrolysis process, homopolymerization cohydrolysis process, copolymerization approach, inverse emulsion polymerization, precipitation polymerization and radiation polymerization.

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 polyacrylamide used for?

1. Introduction Polyacrylamide (PAM) is widely used in various industries, such as wastewater treatment; oil-displacing; paper making; textile printing and dyeing; dredging; and cosmetics . It is mainly polymerized by acrylamide (AM) and the molecular weight can reach 1.5 million to 20 million.

Does nonionic polyacrylamide affect the flocculation process of removing clay?

The presence of nonionic polyacrylamide has slight effect on the flocculation process efficiency of removing clay from industrial wastewater. On the other hand, usin g o f prepared flocculent, it was found that the presence of soap in water in large concentrations has a negative effect on flocculation process.

Does biological filtration improve polyacrylamide biodegradation?

Freedman, D. E. et al. Biologically active filtration for fracturing flowback and produced water treatment. J. Water Process Eng. 18, 29–40 (2017). Dai, X. et al. Waste-activated sludge fermentation for polyacrylamide biodegradation improved by anaerobic hydrolysis and key microorganisms involved in biological polyacrylamide removal.
