MAGNAFLOC-1011 is a high-performance cationic polyacrylamide flocculant widely used for solid–liquid separation in municipal and industrial wastewater treatment, pulp and paper production, mining, mineral processing, sludge dewatering, and other industrial applications. Its high cationic charge density and high molecular weight make it highly effective in aggregating negatively charged suspended solids, forming large, dense, and shear-resistant flocs. These properties improve settling, clarification, thickening, and dewatering performance. MAGNAFLOC-1011 is available as a water-soluble powder or liquid emulsion and is prepared as a dilute aqueous solution prior to use.

Flocculation Mechanism

The primary mechanism of MAGNAFLOC-1011 is electrostatic attraction combined with polymer bridging. Negatively charged suspended solids, such as clay, organic matter, mineral fines, and colloidal particles, attract the cationic polymer chains of MAGNAFLOC-1011. These chains adsorb onto particle surfaces, neutralize negative charges, and link multiple particles together, producing large, cohesive flocs that settle rapidly. The resulting flocs are resistant to shear forces, which enhances the overall efficiency of solid–liquid separation.

MAGNAFLOC-1011 is effective in high-solids slurries, low-turbidity waters, and mixed industrial effluents. Its performance remains stable across a wide pH range, varying salinity, and diverse water chemistries, making it versatile for multiple industrial applications.

Municipal Wastewater Treatment Applications

In municipal wastewater treatment, MAGNAFLOC-1011 is widely applied for:

• Sludge thickening in gravity thickeners

• Dewatering using belt presses, centrifuges, and filter presses

• Tertiary clarification of effluent

MAGNAFLOC-1011 accelerates floc formation, increasing floc density and improving settling. It enhances dewatering performance, producing higher cake solids and reducing water content, which lowers sludge disposal costs. Additionally, clarified effluent meets stringent discharge standards, supporting environmental compliance.

Industrial Wastewater Treatment Applications

MAGNAFLOC-1011 is extensively used in industrial wastewater treatment systems containing high levels of suspended solids. Typical industries include:

• Steel and metal processing

• Pulp and paper manufacturing

• Chemical and petrochemical production

• Food and beverage processing

• Power generation and cooling water systems

In these systems, MAGNAFLOC-1011 efficiently aggregates negatively charged particles, facilitating their removal by sedimentation or filtration. It is often used in combination with inorganic coagulants such as ferric chloride, aluminum sulfate, or polyaluminum chloride to increase floc density and improve overall clarification performance. The result is clearer effluent with reduced turbidity and minimal solids carryover.

Pulp and Paper Applications

In pulp and paper operations, MAGNAFLOC-1011 is applied for:

• Whitewater clarification

• Fiber recovery

• Paper machine water treatment

• Sludge dewatering

Its cationic nature enables MAGNAFLOC-1011 to bind negatively charged fibers, fillers, and fines effectively. This improves water recovery, reduces solids loss, and enhances filtration efficiency, leading to optimized mill operation and lower environmental impact.

Mining and Mineral Processing Applications

MAGNAFLOC-1011 is used in mining and mineral processing for:

• Tailings thickening

• Clarification of process water

• Solid–liquid separation in mineral slurries

In slurries containing fine or ultrafine particles, MAGNAFLOC-1011 promotes rapid floc formation, increases settling velocity, and enhances thickener throughput. Dense, stable flocs reduce overflow solids, produce high-quality underflow, and support water recovery, reducing tailings volume and improving operational efficiency.

Coal Preparation and Fine Particle Recovery

In coal preparation plants, MAGNAFLOC-1011 clarifies wash water and facilitates recovery of fine coal particles. Its cationic polymer chains aggregate negatively charged mineral fines and coal particles into shear-resistant flocs that settle rapidly. This enhances recovery of valuable fines, reduces solids loss, and increases overall plant efficiency.

Sludge Dewatering Applications

MAGNAFLOC-1011 is widely used in sludge dewatering equipment such as belt filter presses, centrifuges, screw presses, and filter presses. By promoting 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-1011 is especially effective for sludges with high organic content or mixed inorganic-organic composition.

Construction and Drilling Slurry Treatment

In construction, tunneling, and drilling operations, MAGNAFLOC-1011 treats bentonite and drilling slurries. It effectively separates suspended solids, allowing water reuse on-site and minimizing environmental impact. The dense, stable flocs produced ensure smooth slurry handling, efficient water management, and reduced operational downtime.

Compatibility and Chemical Integration

MAGNAFLOC-1011 is compatible with a wide range of coagulants, pH adjustment agents, and other flocculants. It can be used alone or in combination with anionic or cationic products to optimize flocculation performance. Proper dosing, controlled mixing, and correct sequence of addition are critical for achieving maximum separation efficiency.

Dosage and Preparation Guidelines

Typical dosage of MAGNAFLOC-1011 ranges from 0.5 to 10 g/m³, depending on solids concentration, particle size, and process conditions. The product is generally prepared as a 0.05–0.3% aqueous solution, with adequate hydration time to activate the polymer fully. Correct solution preparation, gentle mixing, and controlled dosing are essential to achieve optimal flocculation and separation performance.

Summary

In summary, MAGNAFLOC-1011 is a versatile, high-performance cationic polyacrylamide flocculant used across municipal and industrial wastewater treatment, pulp and paper processing, mining and mineral processing, coal preparation, sludge dewatering, and construction slurry treatment. Through combined electrostatic attraction and polymer bridging, MAGNAFLOC-1011 forms dense, shear-resistant flocs, improving settling, clarification, thickening, and water recovery while reducing operational costs. Its stable performance under variable conditions and compatibility with other coagulants make MAGNAFLOC-1011 a reliable and efficient solution for a wide range of water and slurry treatment applications.
