What are the applications of polyacrylamide (PAM)?

As a result, PAM is widely used in municipal wastewater treatment, oil extraction, pulp and paper production, and other fields. Polyacrylamide is mainly used in the flocculation, sedimentation, and dewatering processes in municipal wastewater treatment.

Why is polyacrylamide important in wastewater treatment?

The correct use of polyacrylamide will contribute to improving municipal wastewater treatment results, protecting water resources, and achieving sustainable development. In the wastewater treatment industry, polyacrylamide has become an indispensable agent.

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.

How does polyacrylamide (PAM) reduce drag?

Polyacrylamide (PAM) can effectively reduce the frictional resistance of fluids, and adding a small amount of polyacrylamide (PAM) to water can reduce drag by 50-80%. Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed.

What is polyacrylamide used for?

Polyacrylamide (PAM) is a collective term for polymers obtained by the homopolymerization or copolymerization of acrylamide monomers under the action of an initiator. It can be used as a coagulant, retention aid, sludge dewatering agent, and flocculant sedimentation agent, among other uses, and has a wide range of applications.

What is the concentration of polyacrylamide solution?

Generally, the concentration of the polyacrylamide solution should be controlled between 0.1% and 0.3%. Then, the solution is added to the wastewater in an appropriate amount, and the mixture is stirred thoroughly to allow the polyacrylamide to fully contact the impurities in the wastewater.
