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.

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.

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.

What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

What type of polyacrylamide is Apam?

Amphoteric Polyacrylamide. APAM is formed by hydrolysis and copolymerization of vinyl amide and vinyl cationic monomer acrylamide monomer. It is an irregular zwitterionic polymer with both positive and negative charges on the molecular chain. Non-ionic Polyacrylamide.

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.
