In this study, investigated the removal of fluoride in the Juklim springs, high concentration of Fluoride. The results of this study were summarized as follow. According to the result analysis in water quality standard of drinking water, It was appeared that high pH 9.4. Concentration of Fluoride was 15.5mg/L. It is over the ten-times more than standard. After fixing Hot spring possibility at pH 4, In under circumstances Alum 10g/L inlet over 50mL, Fluoride concentration is 1.2mg/L. And In this case Alum 10g/L put into the Alum 90mL, Fluoride concentration is 0.6mg/L. Bringing hot spring water into contact with Ion-exchange at various HRT, pH was stabilized in range of 6.7~7.8 at 1min HRT, Fluoride concentration was more and more decreased as the HRT increased and 15minute, Fluoride concentration was removal under the water quality standard of drinking water. After 30min, Fluoride concentration was almost removed under 0.05mg/L.
