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.

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.

Which polyacrylamide is best for water purification?

PAM has good coagulation qualities that make it the best for water purification. Coagulation is all about changing a liquid to a solid or half-solid state by adding a specific chemical or coagulant. Polyacrylamide products also combine with water to produce insoluble hydroxides.

What is the dosage of polyacrylamide?

Typically, the dosage ranges between 1-10 ppm. Adjust the specific dosage based on the wastewater treatment results. (2) Preparation of pre-dissolved solution: Mix polyacrylamide with water to create a pre-dissolved solution with a concentration between 0.1% and 0.5%.

Which ionic polyacrylamide is best for sewage treatment?

Anionic polyacrylamide can be categorized into strong, medium, and weak. This is according to their hydrolysis reaction. Cationic polyacrylamide is widely used for municipal sewage treatment. Its sludge dewatering qualities make it the best for sewage treatment. Cationic polyacrylamide flocculant is grouped depending on its levels of ionicity.
