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.

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 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?

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 (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.
