What is cationic polyacrylamide (CPAM)?

Cationic Polyacrylamide. In general, CPAM is white powder in appearance with an ionic degree ranging from 20% to 55%. It has the characteristics of high polymer electrolyte and is suitable for the treatment of wastewater with negative charge and rich in organic matter.

What is cationic polyacrylamide used for?

Mining industry: Cationic polyacrylamide (CPAM) is used as a flocculant to settle and dewater mineral tailings, reducing the environmental impact of mining activities. CPAM can improve the settling rate and compaction of tailings, leading to reduced water consumption and improved tailings storage capacity.

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.

What are the different types of polyacrylamide water treatment?

Description: According to ionic characteristics, it can be divided into four types, non-ionic polyacrylamide NPAM, anionic polyacrylamide APAM, cationic polyacrylamide CPAM and amphoteric polyacrylamide. At present, the PAM water treatment is generally anionic type.

Which polyacrylamide is used as a pulp dispersant?

Anionic polyacrylamide can be used as a pulp dispersant. Low molecular weight PAM can be used as a paper strengthening agent. Medium molecular weight polyacrylamide PAM is used as a retention and drainage aid. And high molecular weight polyacrylamide is used as a flocculant in the treatment of papermaking wastewater.

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.
