Application of Anionic Flocculant PRAESTOL 2510 DK
PRAESTOL 2510 DK is a high-molecular-weight anionic flocculant based on anionic polyacrylamide technology and is widely used in solid–liquid separation processes across industrial, municipal, and mineral processing sectors. As an anionic flocculant, PRAESTOL 2510 DK mainly works through a polymer-bridging mechanism, in which long polymer chains adsorb onto the surface of fine suspended particles and link them together to form large, strong, and fast-settling flocs. Due to its excellent flocculation efficiency, broad pH adaptability, and reliable performance under high solids conditions, PRAESTOL 2510 DK is regarded as a versatile and cost-effective solution for clarification, thickening, and dewatering applications.
One of the most important applications of PRAESTOL 2510 DK anionic flocculant is in mining and mineral processing, especially for tailings thickening, concentrate clarification, and process water recovery. Crushing, grinding, flotation, and leaching operations generate large quantities of ultra-fine mineral particles that remain suspended for long periods. Without effective flocculation, gravity settling in thickeners and clarifiers is inefficient.
PRAESTOL 2510 DK effectively bridges fine mineral particles, significantly increasing settling rates and producing dense flocs. Its use results in higher underflow solids concentration and clearer overflow water. The clear overflow can be reused as process water, reducing freshwater consumption and supporting sustainable mining operations. In addition, higher underflow density improves tailings transport, stacking, and storage efficiency, helping mining companies reduce operating costs and improve tailings management safety.
PRAESTOL 2510 DK is widely applied in industrial wastewater treatment across industries such as metallurgy, steel production, power plants, chemical manufacturing, mining-related industries, ceramics, and construction materials. Industrial effluents often contain high levels of suspended solids, metal hydroxides, and fine inorganic particles generated during neutralization and chemical precipitation processes.
When used after inorganic coagulants such as ferric chloride, aluminum sulfate, polyaluminum chloride, or lime, PRAESTOL 2510 DK acts as a flocculant aid. It strengthens floc structure, accelerates sedimentation, and improves clarification efficiency. As a result, treated effluent exhibits lower turbidity and reduced suspended solids, helping facilities meet increasingly strict discharge regulations. Improved solid removal also reduces the load on downstream filtration, membrane systems, or biological treatment units.
Another key application of PRAESTOL 2510 DK anionic flocculant is in sludge thickening and mechanical dewatering. Sludge generated from industrial and municipal treatment processes often contains fine particles that bind large amounts of water, making dewatering difficult and expensive.
PRAESTOL 2510 DK forms large, porous, and shear-resistant flocs that release water more easily during thickening and mechanical dewatering. In gravity thickeners, it increases settling speed and produces higher underflow solids concentration. When applied prior to belt filter presses, centrifuges, screw presses, or plate-and-frame filter presses, PRAESTOL 2510 DK improves cake dryness, reduces polymer consumption, and stabilizes dewatering performance. Reduced sludge volume directly lowers transportation, handling, and disposal costs.
In municipal water treatment plants, PRAESTOL 2510 DK is commonly used as a coagulant aid to enhance flocculation and sedimentation after primary coagulation with alum or iron salts. Raw water often contains fine clay particles, colloids, and natural organic matter that are difficult to remove by coagulation alone.
The addition of PRAESTOL 2510 DK increases floc size and density, resulting in faster settling and improved clarifier performance. Lower residual turbidity improves the efficiency of downstream filtration systems, extends filter run times, and reduces backwash frequency. Overall, the use of PRAESTOL 2510 DK contributes to more stable plant operation and lower operating costs.
In municipal wastewater treatment, PRAESTOL 2510 DK is mainly applied for primary sludge thickening and chemically conditioned sludge treatment. Its strong flocculation capability ensures reliable operation 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 and predictable performance of PRAESTOL 2510 DK makes it particularly suitable for large municipal facilities where operational stability and cost control are critical.
PRAESTOL 2510 DK anionic flocculant is also widely used in the pulp and paper industry, especially 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, allowing valuable raw materials to be recovered and reused in the papermaking process.
Improved white water clarity supports higher levels of internal water recycling, reduces freshwater intake, and lowers effluent discharge. For paper mill sludge, PRAESTOL 2510 DK enhances 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 large amounts of fine solids that must be separated 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.
In summary, PRAESTOL 2510 DK is a highly effective anionic flocculant with broad applications in mining and mineral processing, industrial and municipal wastewater treatment, sludge thickening and dewatering, municipal water treatment, pulp and paper production, and construction slurry management. By significantly improving solid–liquid separation efficiency, water recovery, and sludge dewatering performance, PRAESTOL 2510 DK helps industries and municipalities reduce operating costs, achieve regulatory compliance, and support long-term sustainable water and sludge management practices.
