What is the use of anionic polyacrylamide in water and wastewater treatment?

The main use of anionic polyacrylamides in water and wastewater treatment is as coagulant aid to bridge the coagulated particles formed when an inorganic coagulants such as alum has been used as the primary coagulant. Fig. 2. Hydrolysis of polyacrylamide

What is anionic polyacrylamide polymer (PAAM)?

Anionic polyacrylamide polymer (PAAM) is a commonly used synthetic polymer in the coagulation-flocculation treatment process for industrial wastewater .

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.

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 Polyacrylamides are used in the thickening process of colliery effluent treatment?

1. INTRODUCTION Polyacrylamides are used in the "thickening" process of colliery effluent treatment. The wastewater contains mainly clay particles, in suspension, which are flocculated using non-ionic and anionic polyacrylamides, which have molar masses in the range of 7-15 million g/mol.

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.
