Actually there is no "good" technical solution as F- is very reactive. There fore you have to remove some harmless anions before accessing to F-.
You could consider :
- Alumina Al2O3 filtration : drawbacks: media lifetime, limited efficiency, chemicals (acid+caustic soda) consumption
- , Filtration on Tri-calcic phosphate: drawbacks: single use media, very limited efficiency. (other media can also be assessed for a pilot plant like CAG, Serpentine etc.)
- Ion exchange (resins) : drawbacks: resins lifetime, chemicals consumption, water authority agreement for resins
- RO-electrodialysis : drawbacks : electrical consumption, brine
Good luck

These work. In some places they used bone char for small quantities.
