What is polyacrylamide used for?

Polyacrylamide and its co-polymers are used as flocculants or coagulants in industrial wastewater treatment .Homo-polymer is used in this application and can be either nonionic, cationic or anionic depending on the types of wastewater needs to be treated. Also polyacrylamide can be prepared either as linear or as cross-linked.

Why do water treatment plants use polyacrylamide?

This allows water treatment plants to greatly improve the removal of total organic content (TOC) from raw water. Another common use of polyacrylamide and its derivatives is in subsurface applications such as Enhanced Oil Recovery.

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.

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 anionic polyacrylamide used for?

Anionic polyacrylamide can pick up positively charged particles (clay, sand), much like a magnet picks up nails and other metal objects. APAM can be widely used in waste water treatment of chemical industry, municipal sewage treatment, such as coal washing, mineral processing, metallurgy, iron and steel industry and electronic 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.
