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 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.

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%.

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.

What is the concentration of polyacrylamide solution?

Generally, the concentration of the polyacrylamide solution should be controlled between 0.1% and 0.3%. Then, the solution is added to the wastewater in an appropriate amount, and the mixture is stirred thoroughly to allow the polyacrylamide to fully contact the impurities in the wastewater.
