<p>A desalination system comprises an electrical separation device configured to receive and ionize a first stream for desalination and a crystallization device. The crystallization device is configured to provide a second stream to the electrical separation device to carry away ions from the first stream, and defining a crystallization zone for facilitating precipitation of the ions and a solid-liquid separation zone in fluid communication with the crystallization zone for separation of the precipitate. A desalination method is also presented.</p>
