Fluoride Ion Removal from Liquid Media by Precipitation

precipitation of fluoride can practically reduce the residual fluoride concentration to 10 15 mg183;L 1 or even lower but not below the 5 mg183;L 1 legal limit stipulated by the Romanian legislation. The lime based fluoride removal can be improved by using an improved variant of ion flotation, part of the adsorptive bubble separation methods.
