Application of MAGNAFLOC-355 SSK

MAGNAFLOC-355 SSK is a high-performance anionic polyacrylamide flocculant designed for demanding solid–liquid separation processes. With its high molecular weight and optimized anionic charge density, MAGNAFLOC-355 SSK provides strong polymer-bridging capability, enabling the rapid aggregation of fine suspended particles into large, stable flocs. This makes MAGNAFLOC-355 SSK particularly suitable for applications involving mineral suspensions, inorganic fines, and high-solids slurries in mining, industrial wastewater treatment, and sludge management systems.

Mining and Mineral Processing

One of the most important applications of MAGNAFLOC-355 SSK is in mining and mineral processing. Ore beneficiation processes such as crushing, grinding, flotation, and washing generate large volumes of tailings slurry containing ultra-fine mineral particles. These fine particles are difficult to settle naturally and can severely limit thickener performance if not properly flocculated.

When MAGNAFLOC-355 SSK is applied in thickeners and clarifiers, its long polymer chains adsorb onto particle surfaces and form bridges between particles. This results in the formation of large, dense flocs that settle rapidly. The application of MAGNAFLOC-355 SSK significantly increases settling rates, improves thickener throughput, and produces higher underflow solids concentration. Clear overflow water can be recycled back into the plant as process water, reducing freshwater consumption and supporting sustainable mining operations.

Tailings Thickening and Water Recovery

MAGNAFLOC-355 SSK is widely used in tailings thickening systems, including conventional, high-rate, and high-density thickeners. Effective flocculation is essential in these systems to ensure stable bed formation and consistent operation under varying feed conditions.

MAGNAFLOC-355 SSK forms strong, shear-resistant flocs that maintain integrity even under high hydraulic and mechanical stress. This stability ensures reliable thickening performance and excellent overflow clarity. Improved water recovery reduces the demand for makeup water and minimizes water losses to tailings storage facilities. At the same time, higher underflow density reduces the volume of tailings slurry, improving transport efficiency and tailings storage management.

Industrial Wastewater Treatment

Another major application of MAGNAFLOC-355 SSK is in industrial wastewater treatment. Industries such as metallurgy, steel production, power generation, chemical manufacturing, ceramics, stone processing, and construction materials generate wastewater containing high levels of suspended solids, metal hydroxides, and inorganic fines.

In these systems, MAGNAFLOC-355 SSK is typically used after inorganic coagulants such as ferric chloride, aluminum sulfate, polyaluminum chloride, or lime. While the coagulants destabilize colloidal particles, MAGNAFLOC-355 SSK enhances floc growth and strength, accelerating sedimentation and clarification. The result is low-turbidity effluent suitable for discharge or reuse. Improved clarification also reduces the load on downstream filtration, membrane, or biological treatment processes, improving overall plant efficiency and reducing operating costs.

Sludge Thickening and Dewatering

MAGNAFLOC-355 SSK plays a key role in sludge thickening and mechanical dewatering. Sludges generated from mining operations and industrial wastewater treatment plants often contain fine particles that retain large amounts of water, making dewatering difficult and expensive.

The application of MAGNAFLOC-355 SSK improves sludge conditioning by forming large, porous flocs that release free water more easily. In gravity thickeners, it increases settling speed and underflow solids concentration. When applied prior to belt filter presses, centrifuges, screw presses, or filter presses, MAGNAFLOC-355 SSK improves cake dryness and filtrate clarity. Reduced sludge volume leads to lower transportation, handling, and disposal costs, while more stable dewatering performance improves plant reliability.

Municipal Water and Wastewater Treatment

In municipal water treatment, MAGNAFLOC-355 SSK is often used as a coagulant aid to enhance flocculation following primary coagulation with aluminum or iron salts. Raw water typically contains fine clay, silt, and colloidal particles that are difficult to remove by coagulation alone. MAGNAFLOC-355 SSK increases floc size and density, improving sedimentation efficiency and clarifier performance. Better turbidity removal enhances downstream filtration efficiency and helps maintain consistent treated water quality.

In municipal wastewater treatment, MAGNAFLOC-355 SSK is mainly applied for sludge thickening and chemically assisted clarification. Its stable performance under fluctuating flow rates and solids loading makes it suitable for large treatment plants that require reliable and predictable operation.

Pulp and Paper Industry

MAGNAFLOC-355 SSK is also used in the pulp and paper industry, particularly for white water clarification, fiber and filler recovery, and paper mill sludge dewatering. Fine fibers, fillers, and pigments suspended in white water are effectively flocculated, allowing valuable raw materials to be recovered and reused. Improved white water clarity supports higher internal water recycling rates, reduced freshwater consumption, and lower effluent discharge.

Environmental and Economic Benefits

The application of MAGNAFLOC-355 SSK delivers significant environmental and economic benefits. Enhanced solid–liquid separation improves water recovery, reduces sludge generation, and supports compliance with strict environmental regulations. Improved dewatering efficiency lowers energy consumption and chemical usage, resulting in reduced operating costs. The ability to recycle process water and reduce waste volumes contributes to more sustainable and cost-effective operations.
