Meanwhile, fluoride-containing wastewater generated by industries such as semiconductors, glass, and electroplating also faces stringent discharge standards. Among numerous defluorination technologies, activated alumina has become one of the most widely used solutions due to its high efficiency, reliability, and cost-effectiveness.
Core Application Areas:
1. Drinking Water Defluoridation:
Centralized Water Plants: Provides core filtration media for large water plants in high-fluoride areas, ensuring safe drinking water for community residents.
Small-scale Community/Township Water Purification Stations: Provides clean drinking water for small to medium-sized populations as an economical and practical solution.
Household and Commercial Water Purifiers: Installed at the end of RO reverse osmosis or ultrafiltration water purifiers as a dedicated defluoridation filter for deep treatment, ensuring pure and safe drinking water.
2. Industrial Wastewater Deep Treatment:
For industrial sectors with strict emission requirements, activated alumina can effectively reduce the fluoride concentration in wastewater to within emission standards.
Semiconductor and Electronics Industry: Treats fluoride-containing wastewater generated during chip etching and cleaning processes.
Glass and Ceramic Industry: Treats fluoride-containing waste gas and wastewater from production processes.
Phosphorus Chemicals and Metal Smelting: Solves the problem of inherently high-fluoride wastewater in processes.
3. Other Applications:
In addition, it can be used as a highly efficient desiccant for gas and liquid drying, and is widely used as a catalyst carrier in petrochemical and other fields.
Why Choose Activated Alumina?
High Defluoridation Efficiency: It exhibits excellent fluoride removal rates, consistently maintaining effluent fluoride levels below the internationally recognized standard of 1.0 mg/L.
High Mechanical Strength: The particles are wear-resistant, do not easily pulverize, have a long service life, and can withstand repeated rinsing and regeneration.
Regenerable and Low-Cost: After adsorption saturation, most of the adsorption capacity can be restored through proper processes, significantly reducing long-term operating costs.
Mature and Reliable Technology: Decades of practical experience have proven the process's stability, clear operating parameters, and controllable risks.
