FLOPAM AN945 is a high-performance, high-molecular-weight anionic polyacrylamide designed for solid–liquid separation applications where exceptionally fine particles must be aggregated, settled, or dewatered. Known for its long polymer chains, medium-to-high anionic charge density, and fast floc-building capability, FLOPAM AN945 is widely used across mining, industrial wastewater, oilfield operations, and many process industries that depend on reliable flocculation and clarification. Its applications are diverse, but they share a common goal: improving process efficiency, increasing throughput, and ensuring clean water recovery.
The primary application of FLOPAM AN945 is in mineral processing and mining tailings treatment, where large volumes of slurry must be clarified to recover water and manage solids. Many ore processing circuits—such as copper, gold, bauxite, nickel, phosphate, manganese, coal, and rare earth beneficiation—generate ultra-fine tailings that settle extremely slowly without chemical assistance. FLOPAM AN945 accelerates settling by forming large, dense flocs through polymer bridging. These flocs settle quickly under gravity, which reduces thickener residence time, improves overflow clarity, and increases the overall capacity of settling equipment. Mines benefit from reduced water consumption, faster recycling of process water, and improved stability of tailings storage facilities, as the resulting underflow is more compact and easier to manage.
In bauxite refining and alumina production, FLOPAM AN945 is used particularly in red-mud settling and washer circuits. The Bayer process produces a highly alkaline, fine red-mud slurry that is difficult to clarify. AN945 withstands the alkaline environment and effectively flocculates the suspended solids, producing a clear pregnant liquor suitable for downstream precipitation. It also improves mud compaction, reducing the volume of residue requiring disposal and increasing efficiency in the counter-current washing (CCD) stages. Better washing efficiency reduces soda losses, improves process economics, and enhances the environmental performance of residue handling systems.
A second major field of application is industrial wastewater treatment, where AN945 is used as a flocculant for suspended solids removal and sludge dewatering. Wastewater streams from steel plants, coal washing facilities, chemical production, textile dyeing, paper manufacturing, food processing, and metal finishing often contain negatively charged colloids that resist settling. FLOPAM AN945 transforms these dispersed solids into easily separated flocs. It increases sedimentation rates, enhances dissolved air flotation (DAF) performance, and dramatically improves sludge dewatering on centrifuges, filter presses, belt presses, and screw presses. By producing more robust flocs that release water more readily, AN945 reduces sludge disposal volumes and lowers overall treatment costs.
In oilfield and petroleum-related applications, FLOPAM AN945 is used in produced-water clarification, drilling mud treatment, and oil sands tailings separation. Produced water often contains fine clays, scale particles, formation solids, and emulsified oil droplets that must be removed before recycling or disposal. AN945 helps form large, shear-resistant flocs that remove suspended solids efficiently when used alongside coagulants such as alum, PAC, ferric sulfate, or polyamines. In oil sands operations, the polymer plays a key role in tailings settling and consolidation, helping operators accelerate water recovery and reduce the environmental footprint of tailings ponds. Its ability to flocculate fine clays under variable ionic and temperature conditions is critical for operational stability.
Construction and tunneling industries also rely on FLOPAM AN945 for slurry treatment and sediment control. Bored pile construction, tunneling, diaphragm walls, and trenching produce slurries containing bentonite, cement fines, silica, limestone dust, and clay particles. AN945 enables rapid clarification of slurry water, allowing the recovered water to be reused onsite. This contributes to significant cost savings and supports environmental compliance by reducing turbidity before discharge. In aggregate washing, sand washing, and quarry operations, AN945 improves settling of wash fines, increases clarity of recycle water, and helps reduce the footprint of settling ponds.
Another widespread application area is paper and pulp mill wastewater, where the polymer assists in fiber recovery, white-water clarification, and sludge dewatering. Organic solids, fiber fines, kaolin, and fillers respond well to high-molecular-weight anionic polyacrylamides, and AN945 is often selected for its ability to form durable flocs even at lower dosages. This reduces load on downstream biological systems and improves overall plant water balance.
In chemical manufacturing, petrochemicals, and refinery effluent treatment, FLOPAM AN945 is frequently used to remove pigments, inorganic fines, catalyst residues, emulsions, and polymer fines. When paired with suitable coagulants, it enhances aggregation and improves precipitation of contaminants that otherwise remain dispersed.
In the food and beverage industry, wastewater streams from starch plants, sugar mills, dairy operations, slaughterhouses, beer breweries, and vegetable processing often contain organic solids, proteins, and colloidal particles. AN945 helps settle these solids efficiently, improving effluent quality and ensuring compliance with environmental discharge standards. It is also used in primary clarification and flotation steps to support organic load reduction.
One of the key advantages of FLOPAM AN945 is its versatility and stability across different pH levels, temperatures, and ionic strengths. The polymer maintains strong floc strength under moderate hydraulic shear, making it compatible with both high-rate thickeners and dynamic dewatering equipment. In systems where slurry characteristics change frequently, AN945 provides consistent performance, reducing the need for continuous operator intervention.
In summary, the application of anionic polyacrylamide FLOPAM AN945 spans mineral processing, red-mud settling, industrial effluent treatment, sludge dewatering, oilfield water clarification, construction slurry treatment, and numerous other sectors requiring efficient solid–liquid separation. Its high molecular weight, strong bridging capability, and adaptability to challenging suspensions make it a preferred flocculant for improving process performance, enhancing water recovery, and reducing environmental impact across a wide range of industries.
