Premium CPAM Polymer Powder Wastewater Clarification Mining Papermaking Solutions

Cationic polyacrylamide (CPAM) is a water-soluble synthetic polymer derived from acrylamide monomers, modified with cationic functional groups (e.g., quaternary ammonium groups). It belongs to the family of polyelectrolytes and is characterized by its high molecular weight (typically 5–20 million Daltons) and strong positive charge density.

The cationic nature of CPAM enables it to interact effectively with negatively charged particles, colloids, and organic matter in aqueous systems. This makes it a versatile flocculant and coagulant aid widely used in industries such as water treatment, papermaking, and oil recovery.

High Cationic Charge Density: Efficiently neutralizes negatively charged particles, enabling rapid flocculation even at low dosages.

Adjustable Molecular Weight: Tailored for specific applications (e.g., low MW for filtration aids, high MW for sludge dewatering).

Broad pH Compatibility: Effective in pH ranges of 4–10, suitable for diverse industrial environments.

Low Toxicity: Degrades into non-harmful byproducts under natural conditions, meeting environmental regulations.

Versatility: Compatible with inorganic coagulants (e.g., PAC, alum) for synergistic effects.

Cost-Effectiveness: Reduces operational costs by minimizing sludge volume and energy consumption.

CPAM is widely applied in various industries thanks to its outstanding binding and bridging capabilities:

A. Water and Wastewater Treatment
- Drinking Water Purification: Removes suspended solids, organic matter, and pathogens by neutralizing colloidal charges and forming large, settleable flocs.
- Municipal/Industrial Wastewater Treatment: Enhances sludge dewatering efficiency, reduces sludge volume, and clarifies effluent.
- Mining Wastewater: Aggregates fine particles (e.g., clay, coal slurry) for easier separation.

B. Paper and Pulp Industry
- Retention and Drainage Aid: Improves retention of fine fibers and fillers (e.g., calcium carbonate) in paper sheets, reducing raw material costs.
- Waste Paper Recycling: Strengthens recycled fibers and removes ink residues.

C. Oil and Gas Industry
- Drilling Fluid Additive: Stabilizes boreholes and reduces fluid loss.
- Enhanced Oil Recovery (EOR): Adjusts water viscosity and improves oil displacement efficiency.

D. Textile and Dyeing
- Treats dye-containing wastewater by adsorbing and precipitating colorants.

E. Agriculture
- Soil conditioner to reduce erosion and improve water retention.
