Anionic Polyacrylamide (APAM) – Premium Flocculant & Polyelectrolyte
Anionic Polyacrylamide (APAM) is an ultra-high molecular weight, water-soluble linear polymer engineered for high-efficiency solid-liquid separation. It carries a negative ionic charge, allowing it to rapidly bind with positively charged particles in suspension. This chemical is highly effective as a primary flocculant or coagulant aid, bridging fine particles together to form dense, fast-settling flocs.
Optimized for the South African market, Brand Chemical Supplies provides high-purity APAM designed to meet the rigorous demands of mining, mineral processing, municipal water clarification, and heavy industrial wastewater treatment.
Key Applications
-
- Mining & Mineral Processing: Accelerates tailing thickening, facilitates rapid sedimentation, and optimizes wastewater recycling in coal washing, gold processing, platinum extraction, and base metal mining.
- Industrial & Municipal Wastewater: Serves as a primary sediment support chemical after initial precipitation, removing suspended organic solids, heavy metals, and colloidal material.
- Sludge Dewatering: Enhances filtration, thickening, and cake-moisture reduction inside industrial filter presses, belt presses, and centrifuges.
- Agricultural Soil & Runoff Control: Applied to irrigation water or agricultural soil to minimize topsoil erosion, enhance water retention, and reduce nutrient leaching into natural water bodies.
- Pulp & Paper Processing: Works as a highly effective retention aid and drainage accelerator to improve sheet formation, fiber recovery, and process-water clarity.

Features and Benefits
-
- Exceptional Bridging Action: Long polymer chains form robust, large flocs that settle up to several times faster than traditional inorganic coagulants alone.
- Highly Economical Dosage: Delivers optimum separation metrics at exceptionally low parts-per-million (ppm) consumption rates, drastically minimizing overall operational costs.
- Wide pH Adaptability: Maintains highly stable performance metrics across broad pH ranges, cutting down the need for extensive pre-treatment pH adjustments.
- Low Sludge Volume: Produces compact, low-moisture sludge cakes, substantially lowering downstream disposal and transportation expenses.
Solution Preparation & Handling
-
- Preparation: Slowly sprinkle the granular powder into a vortex of clean water while stirring continuously to prevent clumping (often referred to as “fish-eyes”). Keep agitation uniform until completely dissolved.
- Storage: Keep bags sealed tight. Store in a cool, dry, well-ventilated space to protect from moisture, humidity, and direct sunlight.
- Safety PPE: Wear safety goggles, rubber gloves, and a dust mask when handling dry powder to avoid minor skin or respiratory tract irritation.
