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 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 be used as a coagulant aid?

Reduce the amount of flocculant. Under the premise of achieving the same water quality, the use of polyacrylamide as a coagulant aid in combination with other flocculants can greatly reduce the amount of flocculant used. Improve water quality.

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.

How do you dissolve polyacrylamide granular flocculant in sewage?

Don’t add PAM powder/granular flocculant to sewage directly. 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.

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.
