Fluoride Removal - Water and Wastewater Information
Fluoride Removal - Water and Wastewater Information

A pilot-scale ballasted flocculation system was used to remove fluoride from one type of industrial wastewater. The system included the formation of calcium fluoride (CaF2) using calcium hydroxide followed by coagulation sedimentation. Calcium fluoride was recycled as nuclei for enhancing CaF2 precipitation and as a ballasting agent for improving ...

The presence of ,fluoride, anions over 1.5 ppm in drinking water could be harmful [2-4]; therefore, the ,removal, of ,fluoride, ions from industrial ,wastewater, is extremely important. In order to eliminate ,fluoride, from aqueous solutions, various chemical and physical methods were developed [3-4].
