An economic study was conducted to evaluate the costs of fluoride removal by electrodialysis on the basis of industrial and economic data. The investment and operating costs were estimated for an industrial plant with a capacity of 2200 m3/d water consumption for 50,000 per capita according to Moroc

Nitrate content has increased in Morocco, especially in underground water of agrarian areas. Several processes including degradation processes and separation processes can remove nitrate from water. Two separating processes were studied to remove nitrate from brackish underground water: adsorption o

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 condition

Studies have been conduced on a groundwater containing 850–1100 mg/l of total dissolved solids (TDS) and 80 mg/l of nitrate to remove nitrate by coupling electrodialysis and bioreactor. The performances of the pilot plant during the period of the tests (more than one year) were proved. The optimisat
