MAGNAFLOC-155 anionic polyacrylamide is a high-molecular-weight anionic flocculant widely used for solid–liquid separation in municipal water treatment, industrial wastewater management, mining, mineral processing, and sludge handling applications. Designed for efficient flocculation, MAGNAFLOC-155 anionic polyacrylamide promotes rapid formation of large, dense, and shear-resistant flocs, improving settling, thickening, clarification, and dewatering performance. It is typically supplied as a free-flowing powder and prepared as a dilute aqueous solution prior to use.

Flocculation Mechanism

MAGNAFLOC-155 anionic polyacrylamide operates primarily through polymer bridging, in which long polymer chains adsorb onto particle surfaces and link multiple suspended solids together. In aqueous systems, suspended solids such as mineral fines, clay, coal particles, and metal hydroxides often carry low or positive surface charges. The bridging mechanism allows MAGNAFLOC-155 anionic polyacrylamide to form cohesive, dense flocs that settle quickly, enabling efficient solid–liquid separation.

Because MAGNAFLOC-155 anionic polyacrylamide relies mainly on bridging rather than charge neutralization, it performs effectively in high-solids slurries, pre-coagulated suspensions, and inorganic-rich systems. Its performance remains stable across variable pH ranges, salinity levels, and water chemistries, making it suitable for diverse industrial applications.

Application in Municipal Water Treatment

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 before dewatering

The product promotes strong and cohesive floc formation, improving settling efficiency and resulting in clearer overflow and higher sludge solids concentration. Enhanced thickening reduces hydraulic load on downstream filters and increases the stability of plant operations.

Application in Municipal Wastewater Treatment

In municipal wastewater treatment, 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 anionic polyacrylamide enhances the efficiency of gravity thickeners and clarifiers. Improved sludge thickening produces higher cake solids, lower water content, and reduced disposal costs. Additionally, clarified effluent meets stricter discharge requirements, contributing to environmental compliance.

Application in Industrial Wastewater Treatment

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 commonly used following inorganic coagulants such as ferric chloride, aluminum sulfate, or polyaluminum chloride to improve floc density and sedimentation. This leads to clearer effluent, reduced turbidity, and minimal solids carryover.

Application in Mining and Mineral Processing

In mining and mineral processing, MAGNAFLOC-155 anionic polyacrylamide is used for tailings thickening, clarification of recycled process water, and solid–liquid separation in ore beneficiation circuits. In slurries containing fine or ultrafine particles, MAGNAFLOC-155 anionic polyacrylamide promotes rapid floc formation and increases settling velocity. The resulting dense flocs improve thickener throughput, produce high-quality overflow, and increase underflow density. Efficient use of MAGNAFLOC-155 anionic polyacrylamide reduces tailings storage volume and supports water recovery, contributing to sustainable operation.

Application in Coal Washing and Fine Mineral Recovery

In coal preparation and mineral recovery plants, MAGNAFLOC-155 anionic polyacrylamide is applied to clarify wash water and recover fine coal or mineral particles. Its polymer bridging mechanism enables ultrafine particles to aggregate 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, including 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, particularly for inorganic and mineral-rich sludges.

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 effectively separates suspended solids from slurry, enabling water reuse on-site and reducing environmental impact. Strong and stable flocs produced by MAGNAFLOC-155 ensure smooth slurry handling and efficient 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 process conditions. It is usually prepared as a 0.05–0.3% aqueous solution, with adequate hydration time to activate the polymer fully. Proper solution preparation, gentle mixing, and controlled dosing are critical for achieving optimal flocculation and separation performance.

Summary

In summary, MAGNAFLOC-155 anionic polyacrylamide is a versatile, high-performance flocculant 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 stable performance under variable conditions, compatibility with coagulants, and efficiency in high-solids systems make MAGNAFLOC-155 anionic polyacrylamide a reliable choice for diverse industrial and municipal water treatment processes.
