What Is the Application of PRAESTOL 2510 Anionic Polyacrylamide

PRAESTOL 2510 anionic polyacrylamide is a high-molecular-weight anionic flocculant widely used for solid–liquid separation in municipal water and wastewater treatment, industrial effluent clarification, mining, mineral processing, and sludge management. As an anionic polyacrylamide, PRAESTOL 2510 operates primarily through polymer bridging, forming strong, dense flocs that improve sedimentation, thickening, dewatering, and water recovery. The product is typically supplied as a free-flowing powder and prepared as a dilute aqueous solution before application.

General Function and Flocculation Mechanism

In many water and sludge systems, suspended solids such as mineral fines, clay particles, metal hydroxides, and inorganic slurries carry low or positive surface charges. PRAESTOL 2510 anionic polyacrylamide adsorbs onto these surfaces and extends long polymer chains into the solution, creating bridges between particles. This mechanism produces large, cohesive, and shear-resistant flocs.

Because PRAESTOL 2510 relies mainly on bridging rather than charge neutralization, it is effective in high-solids suspensions, pre-coagulated slurries, and inorganic-rich systems. Its performance is stable across a wide range of pH and salinity conditions, making it suitable for diverse process environments.

Application in Municipal Water and Wastewater Treatment

One of the primary applications of PRAESTOL 2510 anionic polyacrylamide is in municipal treatment plants for clarification and sludge management. Typical uses include:

• Sludge thickening in gravity thickeners

• Secondary and tertiary clarification

• Conditioning of primary or mixed sludge prior to dewatering

In these applications, PRAESTOL 2510 increases floc size and improves settling rates, resulting in clearer overflow, higher underflow solids, and more efficient thickening. By enhancing the performance of thickeners and clarifiers, PRAESTOL 2510 reduces hydraulic load on downstream dewatering equipment and contributes to lower operating costs.

Application in Industrial Wastewater Treatment

PRAESTOL 2510 anionic polyacrylamide is widely used in industrial effluent treatment, particularly where wastewater contains high levels of suspended solids. Typical industries include:

• Steel and metal processing

• Power generation and cooling water systems

• Chemical, fertilizer, and petrochemical manufacturing

• Construction material production

In these systems, PRAESTOL 2510 aggregates fine solids that would otherwise remain suspended. When applied after inorganic coagulants such as ferric chloride, aluminum sulfate, or polyaluminum chloride, it strengthens floc structure, improves sedimentation, and produces low-turbidity effluent.

Application in Mining and Mineral Processing

Mining and mineral processing represent a major application area for PRAESTOL 2510 anionic polyacrylamide. It is commonly used in:

• Tailings thickening

• Clarification of recycled process water

• Solid–liquid separation in ore beneficiation

In slurries containing fine or ultrafine particles, PRAESTOL 2510 promotes rapid floc formation and higher settling velocities. This improves thickener throughput, produces clearer overflow water, and increases underflow solids concentration. Efficient water recovery and reduced tailings storage make PRAESTOL 2510 critical in sustainable mining operations.

Application in Coal Washing and Fine Particle Recovery

In coal preparation and mineral recovery plants, PRAESTOL 2510 anionic polyacrylamide is applied to wash water clarification and fine particle aggregation. Coal and mineral slurries often have a wide particle size distribution and variable surface charges, making polymer bridging particularly effective.

PRAESTOL 2510 forms strong, shear-resistant flocs that settle rapidly, improving recovery of valuable fines and reducing solids loss. This enhances overall plant efficiency and supports cleaner effluent discharge.

Application in Sludge Thickening and Dewatering

PRAESTOL 2510 anionic polyacrylamide is widely applied in sludge dewatering using belt filter presses, centrifuges, screw presses, and filter presses. Its action improves water release from sludge, increases cake solids content, and produces clearer filtrate or centrate.

Better dewatering performance reduces sludge volume, cutting transportation, handling, and disposal costs. PRAESTOL 2510 is particularly effective for inorganic and mineral-rich sludges.

Application in Construction and Drilling Slurry Treatment

In construction, foundation, and tunneling projects, PRAESTOL 2510 anionic polyacrylamide is used to treat bentonite and drilling slurries. It effectively separates suspended solids from slurry, enabling water reuse on-site and reducing environmental impact.

Compatibility and Integration with Treatment Chemicals

PRAESTOL 2510 anionic polyacrylamide is compatible with inorganic coagulants, lime, pH adjustment agents, and other flocculants. It is typically applied after coagulation to strengthen floc formation and optimize solid–liquid separation.

Dosage and Preparation

Typical dosage levels of PRAESTOL 2510 anionic polyacrylamide range from 0.5 to 10 g/m³, depending on solids concentration, particle size, and process conditions. The product is prepared as a 0.05–0.3% aqueous solution with adequate hydration time to achieve full polymer activation. Proper mixing and controlled dosing are essential to obtain optimal results.

Summary

In conclusion, PRAESTOL 2510 anionic polyacrylamide is a versatile, high-performance flocculant used in municipal and industrial wastewater treatment, mining and mineral processing, coal washing, sludge thickening and dewatering, and construction slurry treatment. Through effective polymer bridging, PRAESTOL 2510 enhances settling, clarification, and water recovery, reduces operating costs, and supports efficient and sustainable solid–liquid separation in diverse industrial and municipal applications.
