High Charge Density Cationic PAM Flocculant for Sludge Dewatering
Cationic PAM | Sludge Dewatering
High-performance Cationic Polyacrylamide designed for efficient sludge dewatering and solid–liquid separation in organic-rich wastewater treatment systems.
What Is Cationic Polyacrylamide (CPAM)?
Cationic Polyacrylamide (CPAM) is a water-soluble, high-molecular-weight polymer flocculant with positively charged functional groups along the molecular chain.
As a professional CPAM manufacturer and supplier, we provide CPAM products specifically designed for sludge dewatering and solid–liquid separation.
CPAM effectively neutralizes negatively charged organic colloids, activated sludge, and biological solids through charge neutralization and polymer bridging, forming dense flocs with excellent dewatering performance.
It is widely used in municipal sewage treatment plants, industrial organic wastewater systems, papermaking, food processing, textile dyeing, and sludge dewatering equipment.
- Strong Cationic Charge Neutralization
Effectively destabilizes negatively charged sludge particles and organic colloids.
- High Molecular Weight Structure
Forms dense, compact flocs with excellent water release performance.
- Low Dosage, High Efficiency
Achieves optimal dewatering results with minimal polymer consumption.
- Wide Cationic Degree Range
Customized grades available for different sludge types and equipment.
- Easy Dissolution & Safe Handling
Granular form dissolves completely and is non-toxic and non-corrosive.

Main Applications of Cationic Polyacrylamide

CPAM is primarily used in sludge conditioning and mechanical dewatering processes, significantly improving sludge cake dryness and filtration efficiency.

Applied to primary sludge, secondary sludge, and biological sludge in municipal sewage treatment plants.

Effective for food processing, beverage, brewery, textile dyeing, and chemical wastewater with high organic content.

Used as a retention and drainage aid, improving fiber retention and reducing sludge volume.

Enhances color removal and sludge settling in dye wastewater treatment systems.

Efficiently treats grease-, protein-, and COD-rich wastewater and sludge.

Recommended Dosage & Usage of CPAM
CPAM must be fully pre-dissolved before dosing.
Recommended solution concentration: 0.1–0.3%
Typical dosage: 0.05–5 mg/L, depending on sludge characteristics
Add granules slowly into stirred water to avoid agglomeration
Optimal water temperature: 20–40 °C
Jar testing and on-site trials are strongly recommended to determine the optimal CPAM grade and dosage.
