MAGNAFLOC-155 anionic polyacrylamide is a high-molecular-weight anionic flocculant widely employed in solid–liquid separation processes across municipal water treatment, industrial wastewater management, mining, mineral processing, and sludge handling operations. Designed for high-efficiency flocculation, MAGNAFLOC-155 anionic polyacrylamide promotes rapid formation of dense, cohesive, and shear-resistant flocs, enhancing settling, thickening, clarification, and dewatering performance. The product is typically supplied as a free-flowing powder and is prepared as a dilute aqueous solution before use.

Flocculation Mechanism

The primary mechanism of MAGNAFLOC-155 anionic polyacrylamide is polymer bridging, where long polymer chains adsorb onto suspended particles and link multiple solids together. In aqueous systems, particles such as mineral fines, clay, coal, or metal hydroxides often carry low or positive surface charges. MAGNAFLOC-155 anionic polyacrylamide binds these particles, forming large, dense flocs that settle rapidly, facilitating efficient solid–liquid separation.

Because the product relies on bridging rather than charge neutralization, it performs effectively in high-solids slurries, pre-coagulated suspensions, and inorganic-rich systems. Its performance remains consistent across a wide pH range, high salinity, and variable water chemistry, making MAGNAFLOC-155 anionic polyacrylamide suitable for diverse industrial applications.

Municipal Water Treatment Applications

MAGNAFLOC-155 anionic polyacrylamide is widely used in municipal water treatment for:

• Clarification of raw water

• Sedimentation in primary and secondary clarifiers

• Conditioning of sludge prior to dewatering

By promoting strong and cohesive floc formation, MAGNAFLOC-155 anionic polyacrylamide enhances settling efficiency, resulting in clearer overflow and higher sludge solids concentration. This improved thickening reduces hydraulic load on downstream filters and enhances overall plant stability.

Municipal Wastewater Treatment Applications

In municipal wastewater treatment plants, MAGNAFLOC-155 anionic polyacrylamide is applied for:

• Sludge thickening

• Dewatering using belt presses, centrifuges, or filter presses

• Tertiary clarification of treated effluent

By increasing floc size and strength, MAGNAFLOC-155 improves the performance of gravity thickeners and clarifiers. Enhanced sludge thickening produces higher cake solids, lower water content, and reduced disposal costs. Additionally, clarified effluent meets stricter discharge standards, supporting environmental compliance.

Industrial Wastewater Treatment Applications

MAGNAFLOC-155 anionic polyacrylamide is extensively applied in industrial wastewater treatment where effluents contain high levels of suspended solids. Typical industries include:

• Steel and metal processing

• Chemical and petrochemical production

• Fertilizer manufacturing

• Power generation and cooling water systems

• Construction materials and ceramics

In these systems, MAGNAFLOC-155 anionic polyacrylamide aggregates fine particles that are otherwise difficult to settle. It is often used following inorganic coagulants such as ferric chloride, aluminum sulfate, or polyaluminum chloride to enhance floc density and sedimentation. This results in clearer effluent, reduced turbidity, and minimal solids carryover.

Mining and Mineral Processing Applications

Mining and mineral processing represent significant application areas for MAGNAFLOC-155 anionic polyacrylamide. Key applications include:

• Tailings thickening

• Clarification of recycled process water

• Solid–liquid separation in ore beneficiation

In slurries containing fine or ultrafine particles, MAGNAFLOC-155 anionic polyacrylamide promotes rapid floc formation, increases settling velocity, and improves thickener throughput. Dense flocs reduce overflow solids and produce high-quality underflow. Efficient use of MAGNAFLOC-155 reduces tailings storage volume and supports water recovery, contributing to more sustainable operations.

Coal Washing and Fine Particle Recovery

In coal preparation plants, MAGNAFLOC-155 anionic polyacrylamide is applied to clarify wash water and recover fine coal or mineral particles. Its polymer bridging mechanism aggregates ultrafine particles into strong, shear-resistant flocs, improving recovery, reducing solids loss, and enhancing overall plant efficiency.

Sludge Thickening and Dewatering

MAGNAFLOC-155 anionic polyacrylamide is widely used in sludge thickening and dewatering equipment such as belt filter presses, centrifuges, screw presses, and filter presses. By enhancing water release from sludge, it increases cake solids content and produces clearer filtrate or centrate. Improved dewatering reduces sludge volume, lowering transportation and disposal costs. MAGNAFLOC-155 is particularly effective for inorganic and mineral-rich sludges generated in municipal, industrial, and mining operations.

Construction and Drilling Slurry Treatment

In civil engineering, tunneling, and drilling applications, MAGNAFLOC-155 anionic polyacrylamide is used to treat bentonite and drilling slurries. It separates suspended solids efficiently, enabling water reuse on-site and reducing environmental impact. The strong and stable flocs produced by MAGNAFLOC-155 ensure smooth slurry handling and improved water management.

Dosage and Preparation

Typical dosage of MAGNAFLOC-155 anionic polyacrylamide ranges from 0.5 to 10 g/m³, depending on solids concentration, particle size, and system conditions. It is prepared as a 0.05–0.3% aqueous solution with sufficient hydration time to fully activate the polymer. Proper solution preparation, gentle mixing, and controlled dosing are essential to achieve optimal flocculation and separation performance.

Summary

In summary, MAGNAFLOC-155 anionic polyacrylamide is a versatile, high-performance flocculant widely used across municipal and industrial wastewater treatment, mining and mineral processing, coal washing, sludge thickening and dewatering, and construction slurry treatment. By forming large, dense, and shear-resistant flocs through polymer bridging, MAGNAFLOC-155 improves settling, clarification, and water recovery while reducing operational costs. Its stability under variable conditions, compatibility with coagulants, and effectiveness in high-solids systems make MAGNAFLOC-155 anionic polyacrylamide a reliable choice for a broad range of water and slurry treatment applications.
