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.

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.

Does polyacrylamide thicken?

Polyacrylamide (PAM) has thickening effects under both neutral and acidic conditions, and when the pH value is above 10, polyacrylamide (PAM) is easily hydrolyzed. When presenting a semi-network structure, thickening becomes more apparent.

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.
