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 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.

Are cationic and anionic polyacrylamides effective in flocculation of pulp and paper mill wastewater?

The flocculation performances of nine cationic and anionic polyacrylamides with different molecular weights and different charge densities in the treatment of pulp and paper mill wastewater have been studied.

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.

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.

Can polyacrylamide be used to treat pulp and paper mill wastewater?

SVI values of less than 70 ml g −1 are found for all polyacrylamide at their respective optimum dosage. Based on the cost evaluation, the use of the polyacrylamides is economically feasible to treat the pulp and paper mill wastewaters.
