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.

Which is better cationic or anionic polyacrylamide?

Cationic PAM is especially suitable for treating negatively charged organic substances such as high-concentration colloids and suspended solids in wastewater treatment. Due to its complex production process and superior performance, cationic PAM is usually priced higher than anionic polyacrylamide.

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.

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 is anionic polyacrylamide used for?

Additionally, anionic polyacrylamide can also be used as a clarifying agent in the tap water industry to remove suspended solids and colloidal impurities from water, thereby improving water quality. Petroleum Industry: In oil extraction and drilling mud treatment, anionic polyacrylamide can be used as a drag reducer to enhance oil recovery.

How cationic polyacrylamide is used in sludge dewatering?

Cationic polyacrylamide can effectively remove these contaminants through charge neutralization and bridging effects. Additionally, cationic polyacrylamide is widely used in the sludge dewatering process to improve dewatering efficiency and reduce the water content of the filter cake.
