Can cationic polyacrylamide be used in oilfield wastewater treatment?

Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.

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.

Can polyacrylamide bind with cationic suspended solids?

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

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 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.
