What are the applications of cationic polyacrylamide?

Cationic polyacrylamide widely used in sludge and sludge dewatering, municipal sewage and industrial wastewater, waste water treatment and industrial process of solid-liquid separation, greatly improve the sedimentation and clarification, flotation and thickening and dewatering speed, to improve the solid-liquid separation effect.

What are polyacrylamides (Pam)?

Polyacrylamides (PAM) are synthetic polymers available in both powder and liquid (emulsion) form (Needham & Doe, 1987; Chang, 1978; Donaldson et al., 1989). These polymers are manufactured in a variety of ways to yield a wide range of physical and chemical properties that make them candidates for many different oilfield applications.

What is cationic polyacrylamide (CPAM)?

Cationic polyacrylamide (CPAM) is a type of polyacrylamide that has positively charged functional groups on its molecular chains. It is widely used in various industries for its unique properties. Some of the common usages of cationic polyacrylamide are:

Why is cationic polyacrylamide used in oil & gas industry?

Oil and gas industry: Cationic polyacrylamide (CPAM) is used in the enhanced oil recovery process to increase the viscosity of injected water and improve the displacement efficiency of oil. CPAM can reduce the mobility of water and improve the sweep efficiency of oil, leading to increased recovery rates and reduced production costs.

How does polyacrylamide (PAM) work?

Polyacrylamide (PAM) can cause suspended substances to flocculate through electric neutralization and bridging adsorption. It can act as an adhesive through mechanical, physical, and chemical means.

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.
