Product Overview
Cationic Polyacrylamide (CPAM) is a highly efficient wastewater treatment flocculant and polymer flocculant. It is widely used in municipal wastewater treatment, industrial wastewater treatment, sludge dewatering, papermaking (as a retention and drainage aid), oilfield oily wastewater treatment, as well as in industries such as textiles, sugar production, and mining. It offers significant advantages including low dosage, fast flocculation, reduced sludge generation, and stable treatment performance.
Products Description
ECOLINK's Cationic Polyacrylamide is produced using an optimized polymerization process. By precisely controlling reaction conditions, the product achieves stable performance in terms of molecular structure, solubility, and flocculation efficiency. Compared with traditional production methods, it features higher purity and lower residual content, resulting in more stable performance during use. These process advantages not only improve treatment effectiveness but also reduce issues caused by product variability.
It is a water-soluble high-molecular polymer synthesized through the copolymerization of acrylamide and cationic monomers, with positively charged functional groups along the molecular chain. The product appears as white granules or powder, is easily soluble in water, non-toxic, and non-corrosive. As a solid-liquid separation agent, it effectively flocculates negatively charged organic colloids and suspended solids through charge neutralization and adsorption-bridging mechanisms.

Mechanism of Action
Charge Neutralization:
As a solid-liquid separation agent, the CPAM molecular chain carries positive charges that neutralize negatively charged suspended particles, destabilizing them.
Adsorption Bridging:
The high molecular chains can adsorb multiple particles simultaneously, forming larger flocs and accelerating sedimentation, enhancing its performance as a polymer flocculant.
Net Capture and Sweep Flocculation:
At higher concentrations, a network structure is formed that physically captures suspended solids, further demonstrating its effectiveness as a solid-liquid separation agent.

With strict quality control, consistency is maintained across different batches, ensuring reliable performance in real use conditions.
This not only guarantees stable production but also delivers better performance during application.
Customer Benefits: Reduced frequency of on-site adjustments, less operation time, and improved overall efficiency.
Frequently Asked Questions (FAQ)
Q: 1. How to select the appropriate molecular weight and ionic degree?
A: Selection should be based on water characteristics. For low-concentration wastewater, choose high molecular weight (above 12 million); for high-concentration organic wastewater, select high ionic degree (40%–60%); for municipal sludge dewatering, a medium to high ionic degree (30%–50%) is recommended.
Q: 2. What is the recommended dosage?
A: The typical dosage is 0.1–10 ppm. The exact dosage should be determined through jar testing. When used with inorganic coagulants, the CPAM dosage can be reduced.
Q: 3. What precautions should be taken during use?
A: Fully dissolve before use; avoid direct addition of dry powder. Add slowly and evenly during dissolution to prevent clumping. Water temperature should not exceed 50°C. Store in a cool, dry place to prevent moisture absorption and caking.
Q: 4. What is the shelf life of the product?
A: When stored in a cool and dry environment, the shelf life is 2 years.
Q: 5. How to evaluate product quality?
A: High-quality CPAM appears white with good flowability, dissolves without "fish eyes," provides fast flocculation, forms dense flocs, and produces clear filtrate.
