This study presents a sizing and economical analysis program of a stand-alone photovoltaic powered electrodialysis plant emphasizing the combination of the electric generation capacity originating from the available solar energy in the Northeast, that is the largest from Brazil, with the electrodialysis desalination process. The eletroctrodialysis process consists basically of transfer of cations and anions through membranes to a concentrate flow or reject. Comparing with a reverse osmosis plant is ratified that the electrodialysis process process presents one of the smallest costs and specific energy consumptions for salts concentrations up to 5,000 ppm, characterizing most of the brackish water wells of the Northeast, and can contribute to attenuate drinking water supply problem.
