ALCLAR HP-600 is a high–molecular weight anionic polyacrylamide (APAM) specifically designed for efficient solid–liquid separation in industrial and environmental treatment processes. As an anionic flocculant, it mainly works through adsorption and polymer bridging, binding fine suspended particles together to form larger, stronger flocs that settle or dewater more easily. Thanks to its reliable flocculation performance, good solubility, and adaptability to different water chemistries, ALCLAR HP-600 is widely used in mining and mineral processing, alumina refining, industrial and municipal wastewater treatment, sludge thickening and dewatering, paper and pulp production, and industrial water clarification and recycling systems.

1. Mining and Mineral Processing

One of the most important application areas of ALCLAR HP-600 is the mining and mineral processing industry. During crushing, grinding, flotation, and classification, large quantities of fine mineral particles remain suspended in process water. These fines are often slow to settle naturally and can limit plant throughput and water recovery. ALCLAR HP-600 is added to thickeners, clarifiers, and tailings treatment units to promote rapid aggregation of fine solids.

The long polymer chains of ALCLAR HP-600 attach to multiple particles simultaneously, forming large and dense flocs with high settling velocity. This results in clearer thickener overflow, higher underflow solids concentration, and improved recycling of process water. The product is suitable for a wide range of ores, including iron ore, copper, gold, coal, phosphate, and bauxite. By improving tailings dewatering and water reuse, ALCLAR HP-600 helps reduce freshwater consumption, operating costs, and environmental impact.

2. Alumina Refining and Red Mud Treatment

ALCLAR HP-600 is widely applied in alumina refineries operating the Bayer process. In this process, bauxite digestion produces red mud, a highly alkaline residue consisting of extremely fine particles. Efficient separation of red mud from the pregnant liquor is essential to minimize caustic soda losses and ensure stable alumina production.

In primary settlers, mud washers, and secondary clarification stages, ALCLAR HP-600 enhances red mud flocculation and accelerates settling. Its chemical stability under high pH and elevated temperature conditions makes it well suited to harsh Bayer process environments. The use of ALCLAR HP-600 improves overflow clarity, enhances counter-current washing efficiency, reduces soda losses, and supports higher refinery productivity and better process control.

3. Industrial Wastewater Treatment

Another major application of ALCLAR HP-600 is industrial wastewater treatment. Many industries generate wastewater containing suspended solids, inorganic fines, metal hydroxides, and colloidal particles that cannot be effectively removed by physical methods alone. ALCLAR HP-600 is used in primary and secondary clarification systems to aggregate these particles into settleable flocs.

Industries such as metallurgy, power generation, chemical manufacturing, ceramics, mining-related industries, construction materials, and textiles benefit from its strong flocculation performance. When used alone or in combination with inorganic coagulants such as ferric chloride or aluminum sulfate, ALCLAR HP-600 forms robust flocs that settle quickly. This leads to lower turbidity, improved effluent quality, easier compliance with discharge regulations, and reduced sludge volumes.

4. Municipal Wastewater and Sludge Treatment

In municipal wastewater treatment plants, ALCLAR HP-600 is primarily applied in sludge thickening and dewatering rather than direct water clarification. It is used to condition primary sludge, waste activated sludge, or mixed sludge prior to mechanical dewatering.

ALCLAR HP-600 improves floc size and strength, allowing water to be released more easily during dewatering. It is compatible with common dewatering equipment such as belt filter presses, centrifuges, screw presses, and filter presses. Higher cake solids content can be achieved, which reduces sludge volume, transportation frequency, and disposal costs. Its high efficiency also helps plants optimize polymer consumption and overall operating expenses.

5. Paper and Pulp Industry

In the paper and pulp industry, ALCLAR HP-600 is used for white water clarification, fiber and filler recovery, and sludge dewatering. During papermaking, fine fibers, calcium carbonate, kaolin, and other fillers are often lost with process water. ALCLAR HP-600 flocculates these fines, allowing them to be recovered and reused in the production process.

This improves raw material utilization, reduces wastewater load, and stabilizes paper machine operation. In addition, ALCLAR HP-600 is applied in pulp and paper mill effluent treatment plants to clarify wastewater and enhance dewatering of primary and biological sludges, helping mills meet environmental discharge standards and increase internal water recycling.

6. Industrial Water Clarification and Recycling

ALCLAR HP-600 also plays an important role in industrial water clarification and reuse systems. Typical applications include cooling water blowdown treatment, mine water clarification, surface water treatment, and process water recycling. By promoting rapid settling of suspended solids, ALCLAR HP-600 produces clear water suitable for reuse within industrial operations.

This supports sustainable water management practices, reduces freshwater intake, and lowers wastewater discharge volumes, which is increasingly important under strict environmental regulations and water scarcity conditions.

7. Key Performance Advantages

The broad application of ALCLAR HP-600 is driven by several technical advantages. It provides high flocculation efficiency at relatively low dosages, good solubility and handling properties, and reliable performance across a wide pH range. Its anionic nature makes it particularly effective for mineral-rich and metal-containing suspensions and compatible with commonly used inorganic coagulants.

Conclusion

In summary, anionic polyacrylamide ALCLAR HP-600 is a versatile and high-performance flocculant widely used for solid–liquid separation. Its main applications include mining and mineral processing, alumina refining and red mud treatment, industrial and municipal wastewater treatment, sludge thickening and dewatering, paper and pulp operations, and industrial water clarification and recycling. By improving settling efficiency, enhancing water recovery, and reducing operating and disposal costs, ALCLAR HP-600 plays a vital role in modern industrial and environmental treatment systems.
