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 the demand for polyacrylamide in water treatment applications?

Polyacrylamide demand in water treatment applications dominated the market with a revenue share of more than 38.0% in 2022. The rising demand for polyacrylamide to treat municipal sewage, industrial wastewater, and drinking water purification plants is expected to propel demand.

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 polyacrylamide used for?

Flocculate or coagulate solids in a liquid may be one of the largest uses for polyacrylamide which applies to wastewater treatment, and processes like paper making and screen printing. Polyacrylamide (PAM) can be supplied in a powder or liquid form, with the liquid form being subcategorized as solution and emulsion polymer.

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.

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.
