1. Overview
-
Name: Fe-type/Bi-type Fluoride and Chloride Removal Reagent.
-
Application: Used for deep fluoride removal in wastewater or products.
-
Composition, Physical and Chemical Properties, and Storage: The main components are Fe- or Bi-containing compounds. The reagent is in powder form, non-toxic and harmless. It is stored in a dry place after being packaged in bags or drums.
2. Key Specifications
-
Fluoride Ion Residual Concentration after Treatment: Less than 0.5 mg/L.
-
pH Range of Fluoride-Containing Wastewater: Effective for wastewater with pH ranging from 2 to 13.
-
Fluoride Removal Efficiency and Economic Indicators: Fluoride removal efficiency is greater than 95% (for example, in wastewater with 100 mg/L fluoride), with a comprehensive treatment cost of less than 10 yuan per ton.
3. Product Advantages
-
High Removal Rate of Fluoride and Chloride, Low Residual Concentration, and Low Cost.
-
Simple Equipment Requirements: The fluoride removal process only requires stirring and filtration equipment, with low operating energy consumption and simple maintenance.
-
Regeneration and Reuse of Fluoride Removal Products: The fluoride removal products can be regenerated and reused as fluoride removal reagents. The fluoride ions are removed in the form of fluorides, with no waste salt or sludge generated and no need for salt separation processes.
4. Application Cases
The reagents and fluoride/chloride removal equipment have been successfully developed and applied in industrial processes such as fluoride removal in the production of battery-grade lithium carbonate from industrial lithium carbonate and fluoride removal in rare earth mineral products.
