Fluoride Remover

Product Introduction and Advantages

Fluoride Remover is our company's solution developed in response to the trends in wastewater treatment technology and current market conditions. It operates on the basic principle of precipitation + flocculation + synergistic agent, primarily applied in the deep fluorine removal from industrial and municipal wastewater. Focused on the treatment of low-concentration fluorine-containing wastewater (≤20mg/L), the effluent is stable and meets various local discharge standards. It offers multiple functions such as fluoride removal, coagulation, and turbidity reduction. The reagent has high purity, low impurities, minimal dosage, and low sludge production, and is free of calcium, preventing scaling and blockages in pipes and valves over long-term use. It boasts high fluoride removal efficiency, unaffected by changes in wastewater quality, and exhibits high operational stability. The low operation cost, simple system design, ease of operation, and the absence of the need for large-scale equipment make it easy to manage and maintain.

Product Features

Deep Fluoride Removal

Focused on low concentration (≤20mg/L) that meets various emission standards globally, offering multiple functions including fluoride removal, coagulation, turbidity reduction, and suspended solids removal. The formed fluoride precipitate does not undergo phase reversal.

Effectiveness ensured:

Rapid reaction time of just 15-20 minutes, with low dosage required. Can be added and treated during the process according to the actual on-site conditions. The cost of chemical addition is more economical than that of calcium salt defluorination agents, aluminum oxide ion exchange adsorption, etc. The effluent is stable and meets various local discharge standards. It offers multiple functions including defluorination, flocculation, turbidity removal, and suspended solids removal. Application Range: Primarily used for deep defluorination of industrial and municipal wastewater at the end of the treatment process, including low-concentration fluoride wastewater from industries such as metal smelting, coal chemical industry, aluminum processing, glass, electronics, electroplating, and pesticides.

Mechanism of Action

SMCF Fluoride Removal Agent is an independently developed product by Shennmei Technology. It works by utilizing the high positive charge density and moderate polymerization degree of its effective components, which facilitate rapid complexation with F- ions in wastewater, forming stable complexes. Simultaneously, the decrease in positive charge density accelerates the aggregation and precipitation of the complexes, converting free fluoride into particulate fluoride. Through the bridging and capturing effects of high molecular weight flocculants, rapid separation of sludge and water is achieved. The aluminum iron composite salts form colloidal particles in water, with a large specific surface area, positive charge, and high Zeta potential. Due to the small radius and strong electronegativity of fluoride ions, the flocs exhibit strong adsorption for fluoride ions, causing a decrease in Zeta potential, instability of the flocs, and subsequent settling, thereby achieving the goal of fluoride removal from wastewater.

Product Advantages

High-Quality: Purity of the reagent is high, with minimal impurities, requiring less dosage, and low sludge content. Free of calcium, it does not cause scaling or blockages in pipelines or valves upon long-term use.

Cost-effective: Can replace resins and adsorbents, with simple processing equipment, immediate effect upon addition, no complex adjustments required, significantly reduces land occupation and investment costs. Compared to other products on the market, less product is needed, with higher treatment efficiency and lower cost per ton of water treated.

Operation Simple: No need to alter the original water treatment process, no need for additional large equipment or stringent reaction conditions, no complex tuning required, simple to operate.

Primary Application

This product is mainly suitable for industrial water treatment: industries include photovoltaic industry, mining, and extraction, etc.

Usage Instructions

Directly pump the defluorination agent; first dissolve the solid in a dissolver to form a solution of approximately 10% concentration (by weight), and then pump it into the reaction tank. For high-concentration fluorine-containing wastewater, combining with calcium salt treatment yields better results. The dosage of the defluorination agent should be adjusted appropriately based on the on-site conditions and small-scale test plans. The equipment for dissolution, storage, and dosing facilities should be made of corrosion-resistant or anti-corrosion materials.
