Defluoridation of Moroccan groundwater by electrodialysis: continuous operation

Studies have been performed on removal of fluoride from Moroccan groundwater by electrodialysis in continuous operation using a pilot plant. The performances of two anion exchange membranes were compared. An optimisation of electrodialysis operation was carried out for various experimental conditions including, amongst others, the fluoride content in the raw water. The water quality and other parameters were followed to show the optimum operating conditions.
