Fluoride Reduction From Water By Precipitation With Calcium Chloride And Lime

Authors : Atia D. . Hoggui A. .

Abstract

ElOued is known for some diseases caused by fluoride concentration in drinkable water. To reduce it, we have chosen a sample with the highest content of fluoride among many sources in order to precipitate it with Ca(OH)2and CaCl2. In order to get better reduction yield of fluoride, a study has been done on the influencingparameters (concentration, pH, temperature) to choose the best conditions. The remove of fluoride is favorable at low concentration of Ca(OH)2, at room temperature and normal acidity.
