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:

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].

What is cationic polyacrylamide?

Cationic Polyacrylamide is white power or granule, the degree of ion is from 5% to 80%, soluble, good water solubility, can be dissolved in water at any percentage and be undissolved in organic solvents. CPAM shows characteristics of high polymer electrolyte, suitable for wastewater treatment with a negative charge and rich organic matter.

Is cationic polyacrylamide soluble in water?

Cationic polyacrylamide (CPAM) is highly soluble in water and can form clear solutions at low concentrations.Due to the positively charged functional groups, Cationic polyacrylamide (CPAM) can attract and bond with negatively charged particles and suspended solids in water, leading to flocculation and sedimentation.

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.

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.
