Abstract:
     The invention relates to an approach using ion to desalt seawater step by step. It is composed by tank and electrode. It follows nether steps: setting a tank with position difference (width: h), setting outfall every 5-50h and anode and cathode at the both sides of tank, sending direct current, setting position difference as 5-100V/M, inpouring seawater into tank to make velocity of flow reach 0.01-0.5 meter per second, discharging high chroma seawater from outfalls step by step. Then desalted water can be obtained. With a simple technics, low investment and operation cost, it can desalt seawater in a large scale, and especially it adapts to vast littoral.
