Cationic Polyacrylamide
Cationic Polyacrylamide
Overview
Cationic Polyacrylamide (CPAM) is a water-soluble linear flocculant polymer, synthesized through the copolymerization of cationic monomers and acrylamide monomers. It is primarily used for sewage flocculation/sedimentation and sludge dewatering.
Specification
| Appearance | Solid content (%) | Molecular weight (M) | Cationic charge (%) | Dissolution time（min） |
|---|---|---|---|---|
| White powder | ≥88 | 1-10 | 0-95 | 45-90 |
Advantages
Highly economical in use, delivering remarkably effective performance even at very low dosages.
Significantly enhance sludge dewatering efficiency and reduce the moisture content of the filter cake.
Enhances the settling rate of suspended solids during solid-liquid separation in the wastewater treatment process.
Operates effectively over a wide pH range (2-9) and can treat wastewater and sludge under weakly acidic conditions.
Application Fields
Sewage flocculation, sedimentation, and air flotation processes
Sludge dewatering by filter press, suitable for belt filter presses, plate and frame filter presses, centrifuges, etc.
Retention aid and filter aid for papermaking
Construction slurry treatment
River dredging
Minerals selection and sewage disposal
Sand washing
Storage and Precautions
The product is non-toxic, water-soluble, and may cake if moistened.
In case of hands or skin contact, rinse immediately and thoroughly with water.
Store in a dry place at temperatures between 5°C and 40°C.
The prepared liquid polyacrylamide solution should not be stored for extended periods. Storage beyond 24 hours may reduce its efficacy.
It is recommended to use low-hardness water with a neutral pH (6-9) to dissolve polyacrylamide. Using groundwater or reclaimed water will result in reduced product effectiveness.
