MAGNAFLOC-1011 is a high-performance cationic polyacrylamide flocculant specifically designed for solid–liquid separation in municipal and industrial wastewater treatment, pulp and paper processing, mining, mineral processing, sludge handling, and other industrial applications. Its high cationic charge density and high molecular weight make it particularly effective in aggregating negatively charged suspended solids, producing large, dense, and shear-resistant flocs. These characteristics result in enhanced settling, clarification, thickening, and dewatering performance. MAGNAFLOC-1011 is supplied as a water-soluble powder or liquid emulsion and is typically prepared as a dilute aqueous solution prior to application.
The primary mechanism of MAGNAFLOC-1011 is electrostatic attraction combined with polymer bridging. Many suspended solids in aqueous systems, such as clay, organic matter, fines, and colloidal particles, carry a negative surface charge. The cationic polymer chains of MAGNAFLOC-1011 adsorb onto these negatively charged particles, neutralizing the surface charges while simultaneously linking multiple particles through long polymer chains. This dual action produces large, dense flocs that settle rapidly and resist shear forces, significantly improving solid–liquid separation efficiency.
MAGNAFLOC-1011 is highly effective in high-solids slurries, low-turbidity effluents, and mixed industrial waters, and its performance remains stable across a wide pH range and varying ionic strengths. Its ability to operate efficiently in complex water chemistries makes MAGNAFLOC-1011 a versatile choice for diverse industrial processes.
In municipal wastewater treatment, MAGNAFLOC-1011 is widely used for:
Sludge thickening in gravity thickeners
Dewatering using belt presses, centrifuges, and filter presses
Tertiary clarification of effluent
MAGNAFLOC-1011 enhances sludge settling by promoting rapid floc formation and increasing floc density. The product improves cake solids in dewatering operations, reduces water content, and lowers sludge disposal costs. Additionally, clarified effluent meets stricter discharge requirements, contributing to environmental compliance.
MAGNAFLOC-1011 is extensively applied in industrial wastewater treatment, particularly in systems with high concentrations of suspended solids. Typical industries include:
Steel and metal processing
Pulp and paper manufacturing
Food and beverage production
Chemical and petrochemical plants
Power generation and cooling water systems
In these applications, MAGNAFLOC-1011 efficiently aggregates negatively charged solids, 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, reduced turbidity, and minimized solids carryover.
In the pulp and paper industry, MAGNAFLOC-1011 is applied for:
Whitewater clarification
Fiber recovery
Paper machine water treatment
Sludge dewatering
Its cationic nature allows MAGNAFLOC-1011 to efficiently bind negatively charged fibers, fillers, and fines, improving water recovery and reducing solids loss. Enhanced flocculation improves filtration efficiency and reduces the environmental impact of effluent discharge.
MAGNAFLOC-1011 plays a critical role in mining and mineral processing operations, where it is used for:
Tailings thickening
Clarification of process water
Solid–liquid separation in mineral slurries
In slurries containing fine and ultrafine particles, MAGNAFLOC-1011 accelerates floc formation, increases settling velocity, and enhances thickener throughput. The formation of dense, stable flocs reduces overflow solids and produces high-quality underflow, supporting water recovery and reducing tailings volume. This contributes to improved operational efficiency and environmental sustainability.
In coal preparation plants, MAGNAFLOC-1011 is used to clarify wash water and recover fine coal particles. The cationic polymer binds negatively charged mineral fines and coal particles, forming shear-resistant flocs that settle rapidly. This enhances recovery of valuable fines, reduces solids loss, and improves overall plant efficiency.
MAGNAFLOC-1011 is widely applied in sludge dewatering processes, 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. Improved dewatering reduces sludge volume, lowering transportation and disposal costs. MAGNAFLOC-1011 is especially effective for sludge with high organic content or mixed inorganic-organic composition.
In construction, tunneling, and drilling operations, MAGNAFLOC-1011 is applied to treat bentonite and drilling slurries. It separates suspended solids effectively, enabling water reuse on-site and minimizing environmental impact. The stable, dense flocs produced by MAGNAFLOC-1011 ensure smooth slurry handling, efficient water management, and reduced operational downtime.
MAGNAFLOC-1011 is compatible with a wide range of coagulants, pH adjustment agents, and other flocculants. It can be applied alone or in combination with anionic or cationic products to optimize flocculation performance. Proper dosing, sequence of addition, and controlled mixing are critical for achieving maximum efficiency in all applications.
Typical dosage levels of MAGNAFLOC-1011 range from 0.5 to 10 g/m³, depending on solids concentration, particle size, and process conditions. The product is usually prepared as a 0.05–0.3% aqueous solution, with adequate hydration time to fully activate the polymer. Proper solution preparation, gentle mixing, and controlled dosing are essential to achieve optimal flocculation and separation performance.
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. By forming dense, shear-resistant flocs through combined electrostatic attraction and polymer bridging, MAGNAFLOC-1011 enhances settling, clarification, thickening, and water recovery while reducing operational costs. Its stable performance under variable conditions, compatibility with coagulants, and efficiency in high-solids systems make MAGNAFLOC-1011 a reliable solution for a wide range of water and slurry treatment processes.
