1. Product Introduction and Advantages

The SMCF series defluoridation agent is an independently developed national invention product. Our company is based on the development trend of sewage treatment technology and market status. It uses precipitation + flocculation + synergist as the basic principle, and is mainly used for deep defluoridation of industrial wastewater terminals and municipal sewage. field. Focusing on the treatment of low-concentration fluoride-containing wastewater (≤20mg/L), the effluent is stable and can meet the required discharge standards in various places. It has multiple functions such as fluoride removal, coagulation, and turbidity removal. The agent has high purity, few impurities, low dosage, low sludge volume, and does not contain calcium. Long-term use will not cause scaling or blockage of pipelines and valve bodies. It has high fluoride removal efficiency and is not affected by changes in wastewater quality. It has high operational stability, low operating costs, simple system, easy operation, no need to add large equipment, and easy management and maintenance.

3. Product features

Our company independently develops products, based on the principle of precipitation + flocculation + synergist, with multiple synergistic effects of multi-core agents, and with deep fluoride removal at the end of municipal and industrial wastewater as the application field.
Deep defluoridation:

Focusing on low concentrations (≤20mg/L), it can meet emission standards in various places and has multiple functions such as fluoride removal, coagulation, turbidity removal, and suspended solids removal. The fluoride precipitate formed does not reverse phase.
Effective:

The reaction is fast, only 15-20 minutes, and the dosage is small. It can be added during the process according to the actual situation on site. The cost of adding chemicals is more economical than calcium salt defluoridation agent, alumina ion exchange adsorption, etc. The effluent is stable and can meet the emission standards required by various places. It has the functions of defluoridation, coagulation, and turbidity removal. , remove suspended solids and other multiple functions. Scope of application: Mainly used for deep fluoride removal at the end of industrial and municipal wastewater, medium and low concentration fluorine-containing wastewater from metal smelting, coal chemicals, aluminum processing, glass, electronics, electroplating, pesticides and other industries.

Mechanism of action

SMCF defluoridation agent is a product independently developed by Shenmei Technology. Its principle of action utilizes the characteristics of the effective components such as high positive charge density and medium degree of polymerization to promote its hydroxyl site to quickly complex with F- in the wastewater to form a stable complex; at the same time Due to the reduction of positive charge density, the aggregation and precipitation of complexes are accelerated, and the conversion of free fluorine into particulate fluorine is realized. Through the bridging and capturing functions of polymer flocculants, mud and water are quickly separated. The aluminum-iron composite salt forms colloidal particles in the water, which has It has a large specific surface area, a positive charge, and a high Zeta potential, while the fluorine ion has a small radius and strong electronegativity. The floc has a strong adsorption effect on fluoride ions, which reduces the Zeta potential and makes the floc unstable and settles, thereby achieving the purpose of fluoride removal from wastewater.

4. Product advantages

Excellent quality: The agent has high purity, few impurities, low dosage, low sludge volume, does not contain calcium, and long-term use will not cause scaling or blockage of pipes and valve bodies.
Low cost: It can replace resins and adsorbents. The processing equipment is simple and effective immediately after adding it. No complicated debugging is required. It can greatly reduce the floor space and investment costs. Compared with other products on the market, it uses less product and has high processing efficiency. Low cost per ton of water treatment. Simple operation: no need to change the raw water treatment process, no need to add large equipment and harsh reaction conditions, no need for complex debugging, and simple operation.

5. Main uses

This product is mainly suitable for industrial water treatment: the industries involved are photovoltaic industry, mine mining industry, etc.

6. How to use

The slurry defluoridation agent is directly pumped and added. The solid is first added to the dissolving tank to prepare a solution with a concentration of about 10% (mass ratio), and then added to the reaction tank by pump. For high-concentration fluoride-containing wastewater, the treatment effect is better when combined with calcium salt. The dosage of high-efficiency fluoride removal agent should be appropriately adjusted according to the on-site conditions and small-scale test plan. Dissolution, storage equipment and dosing facilities should be made of corrosion-resistant or anti-corrosion materials.
