fluoride removal
http://watermanagementcompany.in/index.php?f=product&pid=40
 Fluoridesorb (FS), a filter media consisting of Fe(O)OH, was investigated for removal of fluoride ion (F) from water. Adsorption was studied in batch experiments at room temperature together with the effect of contact time, pH, initial F concentration, and SO42- and Cl- as interfering anions. Lower pH with higher initial F concentration and longer contact time increased the fluoride removal efficiency.
