Cationic Polyacrylamide CPAM

Cationic Polyacrylamides flocculants are polymers of repetition of unite of cationic monomers of cationic acryl amide which involves NH4+ in each unite. According to its unit polymers Creates positive charge properties in water and can absorb to surface of negative charge containments and polymers and forms flocs

Cationic Polyacrylamide (CPAM) with different length and molecular weight causes versatile applications can achieve as main chemical in water treatment as many fields need. by its ability to accelerate the sedimentation of particles in suspension, promote filtration, and enhance the clarification of solutions by forming large flocs through charge neutralization.

Main application of CPAM is water plant high-efficiency flocculant, paper strengthening agent, domestic sewage and organic wastewater treatment, municipal, textile, and oil field chemical additives

The efficiency of CPAM adsorption capacity and performance influenced by many factors such as molecular size, and chain extension and dosage.


the uses cpam in municipal waste water treatment

Cationic Polyacrylamide (CPAM) is used in municipal wastewater treatment extensively for various purposes.

  • Removal containment: CPAM  flocculation abilities uses in municipal wastewater treatment plants to remove of suspended solids and impurities from sewage. It starts the aggregation of particles and make them easier and so much faster to separate from the water.
  • Water Quality improvement: CPAM contributes to the clarification and purification of wastewater, leading to improved water quality before discharge.
  • Make Danse Sludge: CPAM reduces the amount of sludge produced during the sludge treatment process, leading process cost-effective.
  • Versatile Applications: CPAM finds applications in various stages of municipal wastewater treatment, playing a dual-purpose role in decontamination processes and improving the overall treatment efficiency.




Cationic Polyacrylamide plays is main propose of in sludge dewatering processes due to its fantastic characteristics.

Some factors influence on dewatering process efficiency such as pH, dosage, molecular weight

  1. Dosage: overdose deteriorate sludge in dewatering process and increase costs.
  2. Molecular weight: obviously MW and charge density are crucial parameters that directly impact efficiency in sludge dewatering. So high MW can improve efficiency in neutralizing the negative charge on sludge surfaces and adsorption the flocculation.
  3. Structure: CPAM ability to form a uniform and porous structure which enhance electric transport, which promotes the destruction of extracellular polymeric substances (EPS)
  4. collision probability: CPAM enhances the collision probability between flocculants and sludge particles, facilitating bridging action for colloidal particles.
  5. Impact of pH: The pH level significantly effects on dewatering efficiency by formation influencing influence the formation of flocs and the performance

CPAM application in food industries waste water treatment

Cationic Polyacrylamide (CPAM) is utilized in food industry wastewater treatment for various purposes,

contributing to the effective management of waste streams. Some key uses of CPAM in food industry wastewater treatment include:

  1. Solid Removal: CPAM acts as a flocculant in food industry wastewater treatment, it can use as aid in the aggregation of suspended solids and other containments. It unsure the clarification of wastewater before discharge.
  2. Sludge Dewatering : CPAM has versatile application in sludge dewatering agent in food industries by assisting in dehydration of sludge which produced during the treatment process. It can make high density sludge and enhances efficiency of the treatment process
  3. Pollutant removal: removing of pollution such as solid matter, oil, protein, starch, colloids, sugars, acids, alkalis, salts, and other impurities facilized by CPAM polymer in food industries.
  4. BOD , COD reduction: Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD).are often as big problem which should make solutions to be encounter . CAPM as main solution which reduce BOD and COD, by decreasing in the organic content of the wastewater and minimizing product loss to the waste stream.
  5. environmental issue: CPAM act as eutrophication Prevention in water bodies is reduced which is big issue in fish mortality and water quality deterioration
