Anionic Polyacrylamide for Mining Water and Solid-Liquid Separation
Anionic polyacrylamide is a water-soluble polymer flocculant for wastewater streams with high suspended solids. This APAM grade, identified as CAS 9003-05-8, provides ≥88% solid content for clarification, sedimentation, and dewatering applications.
Vanchor produces APAM through the copolymerization of acrylamide and acrylate salts. This process creates long molecular chains with strong adsorption and bridging ability. As a result, fine particles gather into larger flocs and settle faster in treatment systems.
Ultra-High Molecular Weight APAM for Fast Particle Settling
This product can reach molecular weights above 30 million. Because of this structure, it performs well in mining water, sand washing wastewater, industrial effluent, and other separation processes. The long polymer chains connect dispersed particles and improve floc strength during settling or filtration.
In practice, anionic grades often suit wastewater that contains mineral particles, clay, sand, coal fines, or other negatively responsive solids. Operators can use APAM to improve water clarity, reduce suspended solids, and support downstream sludge handling.
At the same time, different projects may require different molecular weight ranges and charge densities. Vanchor offers selectable specifications to match water quality, dosing conditions, equipment type, and treatment targets. This flexibility helps treatment teams adjust product selection before large-scale use.
Beyond mining and sand washing, APAM also serves municipal wastewater, paper production, chemical processing, and sludge dewatering systems. In addition, its strong flocculation behavior supports processes that need faster settling and clearer supernatant.
For procurement planning, CAS 9003-05-8 and ≥88% solid content help confirm product identity and specification consistency. Vanchor supports stable Anionic Polyacrylamide supply with controlled production, quality checks, and export experience for long-term industrial treatment programs.
Preparation & Usage Guidelines
To achieve the best flocculation performance, follow these professional usage recommendations.
1. Conduct a Jar Test
Before large-scale application, perform a jar test to determine the optimal molecular weight and dosage for your specific water conditions.
2. Prepare Polymer Solution
Dilute APAM with clean water to create a 0.1%–0.3% aqueous solution.
3. Use Suitable Water Quality
For best results, use salt-free water with neutral pH during the dissolution process.
4. Proper Mixing Method
Slowly sprinkle the powder into agitated water to avoid clumping and ensure uniform dissolution.Avoid adding large quantities at once, which may form “fish-eyes” (undissolved gel particles).
