Use of alumina and boric acid for removal of fluoride from drinking water

Please let us know if activated alumina doped with boric acid can form a complex to remove fluoride from drinking water with a long life cycle without regenerating alumina.

Activated alumina will remove fluorides. Boric acid is also removed on activated alumina and will form borofluoride complexes that will also be adsorbed by activated alumina.

That being said, sooner or later the capacity of the activated alumina will be exhausted and if the media is not regenerated, it will stop removing fluorides.
