Cationic Polyacrylamide Uses

Cationic polyacrylamide (CPAM) is utilized across various industries for its unique properties, primarily its positively charged molecular structure. Here are the main applications:

Water Treatment:

  • Sludge Dewatering: CPAM is extensively used in water treatment plants for sludge dewatering. Its positive charge neutralizes the negative charge on sludge particles, promoting aggregation and facilitating the separation of water from the sludge.

  • Clarification and Filtration: In water clarification processes, CPAM aids in the removal of suspended solids by neutralizing their negative charge, facilitating their aggregation for easy filtration.


In the papermaking industry, CPAM can be utilized as a dry strength agent, retention aid, and filtration aid, enhancing the strength and toughness of paper, significantly improving paper quality, saving costs, and increasing the production capacity of paper mills.

Textile Industry:

Cationic Polyacrylamide (CPAM) finds various applications in the textile industry, involving not only wastewater treatment processes such as solid-liquid separation and sludge dewatering but also fiber processing. Here are specific fiber processing application areas:

  • Dye Fixation: CPAM serves as a dye-fixing agent, enhancing dye adherence and reducing dye dispersion on fibers.

  • Antistatic Treatment: As an antistatic agent, CPAM improves fiber's antistatic performance, enhancing fabric comfort and appearance.

  • Finishing Agent: CPAM acts as a finishing agent, improving the feel, appearance, and texture of fibers to meet market demands.

  • Oil Additive: CPAM serves as an oil additive in textile processes, enhancing fiber wetting and oil dispersion.

Mining and Mineral Processing:

CPAM is applied in mining operations for solid-liquid separation processes, aiding in the settling and dewatering of tailings and slurry.

Oil and Gas Industry:

In the oil and gas sector, cationic polyacrylamide is used for:

  • Wastewater Treatment: Facilitating flocculation in wastewater treatment processes.

  • Drilling Mud: Assisting in solid-liquid separation in drilling mud application.

  • Clay stabilizer: Can be employed as a clay stabilizer in oilfields. It prevents the expansion of clay, maintains the stability of the wellbore, and reduces the risk of wellbore collapse.

  • Thickening agent for acidizing in oilfields: Help enhancing the effectiveness of the acid solution in the oil well, increase the permeability of the oil reservoir, and facilitate oil extraction.


CPAM is utilized in agriculture for:

  • Soil Conditioning: Improving soil structure and stability.

  • Erosion Control: Stabilizing soil to prevent erosion.
