Anionic Polyacrylamide PAM: Advanced Flocculant for Mining Wastewater & Industrial Effluent Treatment

Anionic Polyacrylamide (PAM/APAM) is a water-soluble high-molecular-weight polymer that has become an indispensable tool in modern industrial wastewater treatment. With its exceptional flocculating activity and friction-reducing properties, anionic PAM delivers reliable solid-liquid separation across a wide range of challenging effluents—particularly in the mining, oil-field, and heavy industrial sectors where suspended solids loads are high and water clarity targets are stringent.

Our anionic polyacrylamide is manufactured as a white fine-sand shaped powder or colorless transparent colloid, engineered for rapid dissolution and consistent performance. Key technical parameters are summarized below:

The product is available with ionicity levels of 10, 20, 30, or 40, allowing precise matching to specific wastewater characteristics. Custom formulations can also be produced upon special request to meet unique process requirements.

Anionic polyacrylamide functions primarily through a bridging flocculation mechanism. Its ultra-high molecular weight (15–20 million) provides exceptionally long polymer chains that can simultaneously adsorb onto multiple suspended particles, forming large, dense flocs that settle rapidly under gravity. In mining wastewater—which typically contains fine mineral tailings, clay particles, and metal hydroxide precipitates—this bridging action is particularly effective because the negatively charged polymer chains interact favorably with the predominantly positively charged mineral surfaces.

Beyond flocculation, anionic PAM also acts as a friction reducer in liquid systems, making it valuable in drilling mud formulations where reducing pump energy requirements and minimizing equipment wear are critical operational priorities.

1. Mining Wastewater Treatment: Primary application for tailings pond clarification, coal washing effluent, and mineral processing water recycling. Achieves high-rate settling of fine ore particles and reduces turbidity to discharge-compliant levels.
2. Industrial Wastewater: Effective across steel, electroplating, chemical processing, and textile effluents where suspended solids and heavy metal precipitates require rapid separation.
3. Oil-Field & Geological Drilling: Serves as a critical additive in drilling mud systems, improving rheological properties, reducing fluid loss, and stabilizing borehole walls during well boring and geological exploration.

• Ultra-High Molecular Weight: At 15–20 million, delivers superior bridging capacity compared to standard-grade PAM products, enabling lower dosage rates for equivalent treatment outcomes.
• Tunable Ionicity: The availability of four ionicity grades (10–40) ensures optimal charge matching with target wastewater, maximizing flocculation efficiency and minimizing polymer waste.
• High Purity & Certified Quality: With ≥90% solid content and SGS/BV/CPAM certification, the product meets international procurement standards for large-scale industrial operations.
• Friction Reduction: The polymer’s ability to reduce inter-liquid friction translates to energy savings in pumping and mixing operations—a tangible operational cost benefit beyond treatment performance.

We understand that no two wastewater streams are identical. Our anionic PAM products are manufactured under strict quality control protocols, with every batch tested to confirm solid content, molecular weight distribution, and dissolution rate. The SGS and BV certifications provide third-party validation of product consistency and safety, giving international buyers confidence in every shipment. In addition to standard specifications, we welcome custom manufacturing requests to meet specialized process conditions, ensuring that each customer receives the optimal polymer grade for their unique application.
