What is a high molecular weight polyacrylamide (PAM)?

Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater. At present, anionic PAM is most used in the paper industry.

Which polyacrylamide is used as a pulp dispersant?

Anionic polyacrylamide can be used as a pulp dispersant. Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater.

Is polyacrylamide a water soluble polymer?

Polyacrylamide (PAM) is a water-soluble linear high-molecular polymer formed by the polymerization of acrylamide monomers initiated by free radicals. At the same time, it is also a kind of polymer water treatment flocculant.

How do you dissolve polyacrylamide granules?

Please dissolve it in water before use, and then its aqueous solution is used for sewage treatment. Use clean water to dissolve polyacrylamide granules/powder. Water at room temperature is sufficient, and generally does not need to be heated. It dissolves very slowly when the water temperature is lower than 5℃.

What is the application of polyacrylamide?

Therefore, its main application is in the water and wastewater treatment industry. The use of polyacrylamide in this industry reduces the use of other conventional coagulants, which results in a much lower amount of sludge and makes the process highly economical and cost-effective.

How can polyacrylamide and inorganic flocculants improve water quality?

Improve water quality. In drinking water treatment and industrial wastewater treatment, the combined use of polyacrylamide and inorganic flocculants can significantly improve water quality. Improve the strength and settling speed of flocs.
