Application of PRAESTOL 2510 DK Anionic Flocculant
PRAESTOL 2510 DK is a high-molecular-weight anionic flocculant based on anionic polyacrylamide chemistry, designed for efficient solid–liquid separation in a wide variety of industrial, municipal, and mineral processing applications. As an anionic flocculant, PRAESTOL 2510 DK works primarily through a polymer-bridging mechanism, in which long polymer chains adsorb onto the surface of suspended particles and connect multiple particles together to form large, dense, and fast-settling flocs. Owing to its strong flocculation efficiency, good solubility, and stable performance under different operating conditions, PRAESTOL 2510 DK is widely used in clarification, thickening, and dewatering processes where high performance and reliability are required.
One of the most important applications of PRAESTOL 2510 DK anionic flocculant is in mining and mineral processing, especially in tailings thickening, concentrate clarification, and process water recovery. During crushing, grinding, flotation, and leaching operations, large volumes of fine mineral particles are generated. These particles often remain suspended for long periods due to their small size and surface charge, making gravity settling inefficient without chemical assistance.
PRAESTOL 2510 DK effectively bridges fine mineral particles, significantly increasing settling rates in thickeners and clarifiers. Its use results in higher underflow solids concentration and clearer overflow water. Clear overflow water can be recycled back into the plant as process water, reducing freshwater consumption and operating costs. At the same time, higher underflow density improves tailings handling, transport, and storage efficiency, contributing to safer and more sustainable tailings management.
PRAESTOL 2510 DK anionic flocculant is widely applied in industrial wastewater treatment across industries such as metallurgy, steel production, power generation, chemical manufacturing, mining-related industries, ceramics, and construction materials. Industrial effluents from these sectors often contain high concentrations of suspended solids, metal hydroxides, fine inorganic particles, and precipitates formed during neutralization and chemical treatment.
When used after inorganic coagulants such as ferric chloride, aluminum sulfate, polyaluminum chloride, or lime, PRAESTOL 2510 DK acts as an effective flocculant aid. It strengthens floc structure, accelerates sedimentation, and improves overall clarification efficiency. As a result, treated effluent shows lower turbidity and reduced suspended solids, helping facilities comply with increasingly strict environmental discharge standards. Improved solids removal also reduces the load on downstream filtration, membrane systems, or biological treatment units, enhancing overall system stability.
Another major application of PRAESTOL 2510 DK is in sludge thickening and mechanical dewatering. Sludge produced from industrial and municipal wastewater treatment processes often contains fine particles with high water retention, making dewatering difficult and costly. PRAESTOL 2510 DK anionic flocculant forms large, porous, and shear-resistant flocs that release water more easily during thickening and dewatering.
In gravity thickeners, PRAESTOL 2510 DK increases settling speed and produces higher underflow solids concentration. When applied before belt filter presses, centrifuges, screw presses, or plate-and-frame filter presses, it improves cake dryness, reduces polymer consumption, and stabilizes dewatering performance. Reduced sludge volume directly lowers transportation, handling, and disposal costs, providing significant economic benefits for treatment plants.
In municipal water treatment plants, PRAESTOL 2510 DK anionic flocculant is commonly used as a coagulant aid to enhance flocculation and sedimentation after primary coagulation with alum or iron salts. Natural organic matter, clay particles, and fine colloids present in raw water can be effectively aggregated into larger flocs, resulting in faster settling and improved clarifier performance.
The use of PRAESTOL 2510 DK leads to lower residual turbidity, improved settled water quality, and more stable plant operation. Improved clarification also benefits downstream filtration by extending filter run times, reducing backwash frequency, and lowering overall operating costs.
In municipal wastewater treatment, PRAESTOL 2510 DK is mainly applied for primary sludge thickening and chemically conditioned sludge treatment. Its strong flocculation performance ensures reliable operation even under fluctuating flow rates and solids loading. By improving thickening efficiency, PRAESTOL 2510 DK helps wastewater treatment plants reduce sludge volume and optimize downstream dewatering processes.
The consistent performance of PRAESTOL 2510 DK makes it suitable for large-scale municipal facilities where process stability and cost control are critical.
PRAESTOL 2510 DK anionic flocculant also finds important application in the pulp and paper industry, particularly for white water clarification, fiber and filler recovery, and paper mill sludge dewatering. Fine fibers, fillers, and coating pigments suspended in white water can be efficiently flocculated using PRAESTOL 2510 DK, allowing valuable raw materials to be recovered and reused in the papermaking process.
Clearer white water supports higher levels of internal water recycling, reduces freshwater intake, and lowers effluent discharge. For paper mill sludge, PRAESTOL 2510 DK improves drainage characteristics and increases solids content in the dewatered cake, reducing disposal costs and improving overall mill efficiency.
In construction and civil engineering projects, PRAESTOL 2510 DK is used for slurry treatment in tunneling, piling, diaphragm wall construction, and foundation works. Bentonite and cement slurries often contain fine solids that must be removed before water reuse or discharge. PRAESTOL 2510 DK promotes rapid flocculation and clarification, producing clear water suitable for recycling on site and minimizing environmental impact.
The application of PRAESTOL 2510 DK anionic flocculant offers numerous operational advantages, including rapid floc formation, strong and stable floc structure, excellent settling performance, and effective operation at relatively low dosages. It performs well across a wide pH range and under high solids conditions, making it adaptable to diverse water chemistries and process requirements. Its reliable performance helps reduce overall chemical consumption and operating costs.
