The drinkable water in Souf region at the south east of Algeria contains high quantity of fluoride which causes dental fluorosis. To reduce fluoride, we have chosen a sample with the biggest content of fluoride among many sources in order to coagulate it with Fe2(SO4)3·H2O. After that the parameters influencing (concentration, pH, temperature) are studied to choose the best conditions for better reduction.
