Cationic Polyacrylamide

Overview Specification Advantages Application Fields Storage and Precautions

Overview

Cationic Polyacrylamide (CPAM) is a linear high molecular polymer copolymerized from cationic monomers and acrylamide. Its mechanism of action mainly relies on charge neutralization and adsorption bridging, which can effectively flocculate negatively charged colloidal particles to form large and compact flocs, achieving efficient solid-liquid separation. CPAM is extensively applied in wastewater treatment and sludge dewatering for municipal sewage, printing and dyeing, papermaking, food and other industries, with remarkable advantages such as low dosage, fast flocculation and excellent decolorization performance.

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.
