Application of Anionic Polyacrylamide RHEOMAX DR-1050

RHEOMAX DR-1050 is a high-performance anionic polyacrylamide developed for efficient solid–liquid separation in a wide range of industrial and municipal processes. As an anionic polyacrylamide, RHEOMAX DR-1050 is characterized by high molecular weight, strong anionic charge, and excellent water solubility. These properties enable RHEOMAX DR-1050 to act primarily through polymer bridging and floc formation, making it highly effective in clarification, thickening, and dewatering applications. The application of anionic polyacrylamide RHEOMAX DR-1050 is especially important in mining, water treatment, and industrial wastewater management.

1. Mining and Mineral Processing

One of the most important applications of RHEOMAX DR-1050 anionic polyacrylamide is in mining and mineral processing, particularly in tailings thickening and clarification. Mineral beneficiation processes generate large volumes of fine suspended solids that are difficult to settle naturally. RHEOMAX DR-1050 promotes rapid aggregation of mineral fines, significantly increasing settling rates and producing clear overflow water.

In tailings thickeners, RHEOMAX DR-1050 anionic polyacrylamide helps achieve higher underflow solids concentration, which improves tailings handling efficiency and dam stability. Enhanced water recovery is another key benefit, allowing mining operations to reuse process water and reduce freshwater consumption, which is critical in water-scarce regions.

2. Industrial Wastewater Treatment

RHEOMAX DR-1050 anionic polyacrylamide is widely applied in industrial wastewater treatment, including steel mills, power plants, chemical manufacturing, ceramics, and construction material industries. These wastewaters often contain inorganic fines, metal hydroxides, and suspended solids formed during neutralization or precipitation processes.

When used as a flocculant after inorganic coagulants such as ferric salts or lime, RHEOMAX DR-1050 strengthens floc structure and accelerates solid–liquid separation. Improved clarification reduces suspended solids in the treated effluent, helping industries comply with environmental discharge regulations and reduce treatment costs.

3. Municipal Water and Wastewater Treatment

In municipal water treatment, RHEOMAX DR-1050 anionic polyacrylamide is commonly used as a coagulant aid to improve sedimentation and filtration performance. After primary coagulation, RHEOMAX DR-1050 enhances floc size and density, leading to lower turbidity and more stable operation of clarifiers and filters.

In municipal wastewater treatment plants, RHEOMAX DR-1050 is applied in sludge thickening and dewatering, particularly for primary sludge or chemically conditioned sludge. Its strong bridging capability forms large, shear-resistant flocs that release water more easily under mechanical pressure.

4. Sludge Thickening and Dewatering

A key application of RHEOMAX DR-1050 anionic polyacrylamide is in sludge thickening and mechanical dewatering systems, such as belt filter presses, centrifuges, and screw presses. Sludge particles often trap water within their structure, making dewatering inefficient. RHEOMAX DR-1050 improves floc porosity and strength, allowing water to drain freely.

The result is higher cake solids content, reduced sludge volume, and lower transportation and disposal costs. In many cases, the use of RHEOMAX DR-1050 also improves dewatering consistency and reduces overall polymer consumption.

5. Pulp and Paper Industry

In the pulp and paper industry, RHEOMAX DR-1050 anionic polyacrylamide is applied in white water clarification, fiber recovery, and paper mill sludge dewatering. Fine fibers and fillers present in white water can be effectively flocculated, allowing their recovery and reuse. Improved white water clarity supports increased internal water recycling and reduced fresh water demand.

For sludge treatment, RHEOMAX DR-1050 enhances drainage and produces drier sludge cakes, reducing disposal costs and improving mill efficiency.

6. Construction and Civil Engineering

RHEOMAX DR-1050 also finds application in construction and civil engineering, particularly in slurry treatment for tunneling, piling, and concrete operations. It helps separate solids from bentonite or cement slurries, producing clearer water for reuse and reducing environmental impact at construction sites.

7. Operational and Economic Benefits

The application of RHEOMAX DR-1050 anionic polyacrylamide offers multiple advantages, including rapid floc formation, improved settling and dewatering efficiency, high water recovery, and stable performance under varying pH and temperature conditions. Its effectiveness at low dosages makes it a cost-efficient solution for large-scale operations.
