The drinkable water in the south east of Algeria contains high quantity of fluoride which causes dental fluorosis. To decrease fluoride, we have chosen a sample with the biggest content of fluoride among many sources in order to coagulate it with Al2(SO4)3·18H2O. After that the parameters influencing (concentration, pH, temperature) are studied to choose the best conditions for better reduction yield.
