Principle of Fluoride Removal Agent by Henan Dingxin Metallurgical Technology Co., Ltd.

　　Addressing the challenge of high fluoride water exceeding standards in industries such as coal chemical, single crystal silicon, etc., based on cutting-edge research results from the Academy of Sciences. A composite chelation-adsorption fluoride removal agent has been developed based on the characteristics of wastewater quality and treatment processes in typical industries. The study found that the conversion of free fluoride to complexed fluoride and the generation of fluoride ligands are key steps in achieving fluoride removal. PH value, fluoride form conversion, and dosage of the agent are core factors affecting the fluoride removal effect. The design introduces organic chelating agents with strong chelation ability to convert free fluoride into complexed fluoride, and then through a mixture of iron-aluminum-manganese complexes with different degrees of polymerization, hydroxyl numbers, and charge amounts, based on aluminum-fluoride coordination and hydroxyl exchange, a new fluoride removal agent mechanism of chelation-coagulation-adsorption has been created, establishing a new fluoride removal agent that synergizes coordination complexation, co-precipitation, and hydroxyl adsorption.

      Characteristics
    1. Efficiency: Can quickly reduce the concentration of fluoride ions in water, with a high effective removal rate.
    2. Targeted: Mainly aimed at treating fluoride-containing wastewater, reducing the harm of fluoride to human health and the environment.
    Applicable Scope
   1. Industrial wastewater treatment: Industries such as electroplating, electronics, and chemicals generate fluoride-containing wastewater, and the fluoride removal agent can ensure the wastewater meets discharge standards before being released.
   2. Drinking water treatment: Some groundwater or surface water has excessive fluoride content, and the fluoride removal agent can ensure the hygiene of drinking water, making the fluoride content comply with drinking water standards.

　　Product Characteristics

　　CSD Chelation-Coagulation-Adsorption Fluoride Removal Agent

　　Agent Advantages

　　◆ Rich Mechanism of Action

　　The fluoride removal agent synergizes processes such as co-precipitation, coordination complexation, and hydroxyl adsorption to achieve an ideal fluoride removal effect.

　　◆ Low Waste Generation, Low Overall Cost

　　Compared to traditional fluoride removal agents or materials, it does not produce strongly alkaline regeneration waste liquid, and the yield of fluoride sludge is reduced by more than 30%, lowering the overall treatment cost by more than 30%.

　　◆ Wide Applicability

　　Can adjust different processes to suit different fluoride concentrations and scales of drinking water, industrial wastewater, and industrial waste liquid treatment.

　　◆ High Microbial Activity

　　The fluoride removal agent significantly reduces microbial toxicity and negative impacts through the combination of chelating agent components, allowing for long-term use in biochemical systems without reducing microbial activity.

　　◆ Convenient to Use

　　The fluoride removal agent is a liquid agent, easy to add, reducing the handling, dissolving, and other steps during the use of the agent.

　　◆ Significant Auxiliary Effects

　　After the agent is added, it has auxiliary effects such as reducing non-dissolved organic matter in water, lowering water hardness, and reducing suspended solids in water.

　　Application Scenarios

　　Photovoltaic fluoride removal, glass processing fluoride removal, coal chemical fluoride removal, chemical fluoride removal, smelting fluoride removal.
