PRAESTOL DW30 DK is a high-performance anionic polyacrylamide flocculant widely used in solid–liquid separation processes across municipal, industrial, and mining sectors.
PRAESTOL DW30 DK is a high-performance anionic polyacrylamide flocculant widely used in solid–liquid separation processes across municipal, industrial, and mining sectors. As a high molecular weight anionic polymer, PRAESTOL DW30 DK is designed to enhance particle aggregation through polymer bridging, improving settling rates, clarification efficiency, and water recovery. Its versatility, efficiency, and cost-effectiveness make it a preferred solution in complex treatment systems where suspended solids removal is critical.
One of the primary applications of PRAESTOL DW30 DK anionic polyacrylamide is in municipal and industrial wastewater treatment plants. It is commonly applied in primary clarification, secondary clarification, and tertiary treatment stages to promote floc formation and accelerate sedimentation. The anionic charge density of PRAESTOL DW30 DK makes it particularly effective for wastewater streams containing inorganic particles, metal hydroxides, and negatively charged colloids after coagulation.
In industrial wastewater treatment, PRAESTOL DW30 DK is extensively used in sectors such as chemical manufacturing, food processing, textiles, pulp and paper, and metallurgy. It helps reduce turbidity, chemical oxygen demand (COD), and total suspended solids (TSS), enabling treated water to meet discharge or reuse standards. When used in combination with inorganic coagulants such as aluminum sulfate or ferric chloride, PRAESTOL DW30 DK significantly improves overall clarification efficiency.
PRAESTOL DW30 DK anionic polyacrylamide plays a vital role in sludge conditioning and dewatering. It is compatible with various mechanical dewatering equipment, including belt filter presses, centrifuges, screw presses, and filter presses. By forming strong, compact flocs, PRAESTOL DW30 DK enhances water release from sludge, resulting in higher cake solids content and reduced sludge volume.
In municipal sewage sludge dewatering, PRAESTOL DW30 DK is particularly effective for waste activated sludge and mixed sludge after appropriate conditioning. In industrial sludge treatment, it is widely used for sludge generated from mining, metal processing, and chemical industries, where fine mineral particles and high solids content are present. Improved dewatering performance leads to lower transportation and disposal costs, contributing to overall operational efficiency.
Another major application area of PRAESTOL DW30 DK anionic polyacrylamide is mining and mineral processing. It is extensively used in tailings thickening, concentrate dewatering, and process water clarification. In mineral beneficiation circuits, PRAESTOL DW30 DK improves settling rates in thickeners, allowing for higher throughput and improved underflow density.
In tailings management systems, PRAESTOL DW30 DK supports efficient solid–liquid separation, enabling rapid water recovery and reducing the environmental footprint of tailings storage facilities. It is suitable for a wide range of ores, including coal, iron ore, copper, gold, phosphate, and bauxite. Its high molecular weight structure allows it to bridge fine mineral particles effectively, even under challenging pH and salinity conditions.
With increasing emphasis on sustainability and water reuse, PRAESTOL DW30 DK anionic polyacrylamide is widely applied in industrial water recycling systems. It helps clarify process water streams, making them suitable for reuse in production operations such as cooling, washing, and slurry transport. By improving water recovery rates, PRAESTOL DW30 DK reduces freshwater consumption and minimizes wastewater discharge.
In industries such as steel manufacturing, power generation, and mineral processing, the use of PRAESTOL DW30 DK contributes to closed-loop water systems, improving resource efficiency and regulatory compliance.
PRAESTOL DW30 DK anionic polyacrylamide is supplied in a dry granular or powder form, offering excellent storage stability and ease of transportation. When properly dissolved and dosed, it exhibits rapid flocculation kinetics and consistent performance. Its compatibility with a wide range of coagulants and treatment systems allows flexible integration into existing processes without major equipment modifications.
From an operational perspective, PRAESTOL DW30 DK provides advantages such as low dosage requirements, reduced chemical consumption, and stable performance across varying water qualities. These benefits make it a reliable choice for both continuous and batch treatment operations.
The application of PRAESTOL DW30 DK anionic polyacrylamide contributes to environmental protection and cost optimization. Improved solid–liquid separation reduces pollutant discharge, enhances water reuse, and supports compliance with environmental regulations. Economically, its high efficiency translates into lower overall treatment costs, reduced sludge handling expenses, and improved process productivity.
