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 the role of polyaluminum chloride in sewage treatment?

At the same time, polyaluminum chloride can also play a role in assisting coagulation, helping polyacrylamide to accelerate the sedimentation, making the water clear and sludge sinking. This is why need to add PAC first and then PAM in sewage treatment process.

What are the uses of polyaluminum chloride and polyacrylamide?

In the sewage treatment of papermaking, steel, metallurgy, mineral processing, chemical, electroplating, slaughter, urban sewage and other industries, it is often necessary to add polyaluminum chloride and polyacrylamide to accelerate the sedimentation rate of pollutants in the water in the process of flocculation and precipitation.

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 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.

Which chemical process is used for sewage treatment?

Meanwhile, research on chemical process for the sewage treatment using poly aluminium chloride (PAC) and polyacrylamide (PAM) that acted as coagulant and flocculant respectively, in Jar Test method was carried out.
