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.

What is polyacrylamide (PAM)?

Polyacrylamide (PAM) is not only a high-performance flocculants, but also because of the high viscosity of aqueous solution, but also a very good thickener. Due to its thickening, flocculation and regulation of rheological properties it can be used as a drilling fluid, fracturing fluid, and polymer flooding in the exploitation of oil extraction.

Which polymers are used in oil fields?

Polymers, such as partially hydrolyzed polyacrylamide (HPAM), are widely used in oil fields to enhance or improve the recovery of crude oil from the reservoirs. It works by increasing the viscosity of the injected water, thus improving its mobility and oil recovery.

What is the use of polyacrylamide in tertiary oil recovery?

2.Polyacrylamide for oil flooding. In the tertiary oil recovery (EOR) with enhanced oil recovery, polyacrylamide can be used to adjust the flowability of injected water, increase the viscosity of the driving fluid, improve the efficiency of water flooding, reduce the permeability of water in the ground, To move forward.

What is organic polymer flocculant cationic polyacrylamide (CPAM)?

The organic polymer flocculant cationic polyacrylamide (CPAM) has the characteristics of a low additive amount, good turbidity removal and water purification effect, and high COD removal efficiency, and it has become the most commonly used polymer flocculant in the oilfield wastewater treatment process [11, 12, 13, 14, 15].

Can cationic polyacrylamide be used in oilfield wastewater treatment?

Author to whom correspondence should be addressed. Cationic polyacrylamide (CPAM) solid particle is one of the most commonly used organic polymer flocculants in oilfield wastewater treatment, but it poses some problems, such as a slow dissolution rate and an easy formation into a “fish-eye” in the process of diluting into aqueous solution.
