What is polyacrylamide (PAM) used for?

In raw water treatment, polyacrylamide (PAM) is used together with activated carbon for the coagulation and clarification of suspended particles in domestic water; in sewage treatment, polyacrylamide (PAM) can be used for sludge dewatering; in industrial water treatment, polyacrylamide (PAM) is primarily used as a formula agent.

Why is polyacrylamide used in water treatment?

With the increasing global water scarcity and escalating environmental pollution, efficient water treatment has become paramount. Polyacrylamide, as a versatile polymer compound, has demonstrated significant achievements in the field of water treatment. PAM is widely used as a coagulant and flocculant in wastewater treatment.

When did polyacrylamide become a drinking water treatment chemical?

Polyacrylamide, acrylic acid polymers and copolymers were endorsed by the NHMRC as drinking water treatment chemicals in 1977 and 1979. The revision undertaken in 2003 did not result in any change to the status of this chemical for the treatment of drinking water.

Can polyacrylamide powder be added to sewage?

Polyacrylamide powder can’t be directly added to sewage. It must be dissolved in water before use, and then use polyacrylamide solution for sewage treatment. Use clean water to dissolve PAM powder. Generally, just use water at room temperature, no need to heat it. However, the dissolution is very slow when the water temperature is lower than 5℃.

Can polyacrylamide powder improve water quality?

In drinking water treatment and industrial wastewater treatment, the use of polyacrylamide powder and other inorganic flocculants can significantly improve water quality. Improve floc strength and settling velocity. The flocs formed by polyacrylamide flocculant have high strength and good settling performance.

How polyacrylamide (PAM) is used in sewage treatment?

In sewage treatment, using polyacrylamide (PAM) can increase the recycling rate of water reuse. In petroleum extraction, polyacrylamide (PAM) is mainly used in drilling mud materials and for enhancing oil recovery, widely applied in drilling, well completion, cementing, fracturing, enhanced recovery, and other oil field extraction operations.
