Why is polyacrylamide used in water treatment?

The anionic polyacrylamide polymers have a high demand for industrial wastewater treatment and municipal sewage treatment as flocculating agents. The increasing impure water discharge from industries, and growing scarcity of potable water, is expected to drive demand for polyacrylamide in water treatment application over the coming years.

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.

What are the different types of polyacrylamide (PAM)?

YASA ET is supplier of three different kinds of PAM: non-ion polyacrylamide (NPAM), cationic polyacrylamide (CPAM), and anionic polyacrylamide (APAM). Click here to learn more. PAM chemical compounds are used to flocculate and coagulate suspended solids in water, wastewater, and soil.

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.

What is ionic polyacrylamide?

The ionic forms of polyacrylamide has found an important role in the potable water treatment industry. Trivalent metal salts, like ferric chloride and aluminium chloride, are bridged by the long polymer chains of polyacrylamide. This results in significant enhancement of the flocculation rate.

How can polyacrylamide be used in waterflooding?

Another common use of polyacrylamide and its derivatives is in subsurface applications such as Enhanced Oil Recovery. High viscosity aqueous solutions can be generated with low concentrations of polyacrylamide polymers, and these can be injected to improve the economics of conventional waterflooding.
