Fluoride Wastewater Treatment Project: 15,000 TPD Capacity Reducing Fluoride from 7 ppm to Below 1 ppm
August 24, 2026
Project Background
A large mining operation faced a critical water treatment challenge: its process water and mine drainage contained elevated levels of fluoride, making direct discharge impossible under increasingly strict environmental standards. The company needed a robust, high-throughput treatment system capable of handling its enormous daily water volume while meeting stringent effluent quality requirements.
Project Challenges
The fluoride-containing wastewater posed several technical hurdles:
- Massive daily flow requiring a treatment capacity of 15,000 tons per day
- Incoming fluoride concentration of 7 ppm, above regulatory discharge limits
- Variations in water quality and suspended solids typical of mining operations
- Demand for reliable, continuous operation with minimal downtime
Conventional single-stage precipitation methods often struggle to achieve ultra-low fluoride levels consistently, especially at such a large scale. A more advanced, multi-stage treatment approach was required.
Our Solution
We designed and delivered a complete defluorination system combining chemical precipitation, coagulation-flocculation, and advanced clarification stages. The system was engineered for high-volume continuous operation and automatic chemical dosing control to maintain stable effluent quality.
Key features of the system include:
- Two-stage reaction tanks with precise pH and dosing control
- High-efficiency clarification and sludge separation units
- Automated monitoring and control for stable operation
- Scalable modular design sized for 15,000 tons per day throughput
Technical Parameters
| Parameter | Value |
|---|---|
| Treatment capacity | 15,000 tons/day |
| Influent fluoride concentration | 7 ppm |
| Effluent fluoride requirement | < 1 ppm |
| Treatment process | Chemical precipitation + coagulation + clarification |
Results & Benefits
After commissioning, the treatment plant consistently delivered effluent fluoride concentrations below 1 ppm, achieving a removal rate of over 85% and fully meeting discharge requirements:
- Fluoride reduced from 7 ppm to below 1 ppm with stable, reliable performance
- Continuous treatment of 15,000 tons of wastewater per day without interruption
- Fully automated operation reducing labor and chemical consumption costs
- Compliance with environmental discharge regulations, avoiding penalties and shutdown risks
- Minimal footprint with optimized sludge handling and disposal
