IPC: C02F1/52
Filed: 2000-03-06
Abstract: PROBLEM TO BE SOLVED: To provide a fluorine-containing water treatment process which comprises adding a Ca compound to fluorine-containing water to precipitate and separate flourine as CaF2 and removing residual Ca2+ ion in the resulting water by cation-exchange resin and enables reduction in concentration of the residual Ca2+ ion by optimizing the amount of addition of the Ca compound without increasing the F- ion concentration in treated water by this CaF2 formation treatment and also reduction in regeneration frequency of the cation- exchange resin. SOLUTION: In this treatment process, when the equivalent amount of a calcium compound to the amount of ions in fluorine-containing water, which ions can be combined with calcium to form their respective hardly soluble salts, is A mg/L (expressed in terms of Ca), the amount of addition of the Ca compound to the fluorine-containing water is adjusted to A to (A-200) mg/L (expressed in terms of Ca).
