The drinkable water in oasis region 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 FeSO4·H2O. After that the parameters influencing (concentration, pH, temperature) are studied to choose the best conditions for better reduction.
