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.

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.

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.

What is anionic polyacrylamide used for?

Polyacrylamide finds applications in pulp and paper production, agriculture, food processing, mining, and as a flocculant in wastewater treatment. Anionic polyacrylamide is suitable for high concentrations of positively charged inorganic suspensions, as well as coarse suspended particles (0.01-1mm), with a Ph value of neutral or alkaline solution.

Can polyacrylamide flocculant improve water purification capacity?

Using organic polyacrylamide flocculant instead of inorganic flocculant, even don’t modify the sedimentation tank, it can increase water purification capacity by more than 20%. In sewage treatment, the use of PAM flocculant can increase the utilization rate of water recycling and can also be used for sludge dewatering.

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.
