Fluoride-Containing
Defluoridation: calcium salt treatment bottoms out at 15–30; achieving the standards of 8 and 2 requires a different mechanism.
Multi-industry projects across China (photovoltaics and semiconductors, display
Pilot to full-scale engineering (3,800 to 45,000 m³/d; influent fluoride 4 to 93
The same "fluoride" has five sets of limits in discharge standards, only one form in solution that can precipitate, and a portion in the laboratory that cannot be measured. This article examines four aspects of the issue: why primary calcium salt precipit
