摘要 |
<p>In electrodialysis for desalting or concentrating an electrolyte solution in desalting chambers and concentrating chambers constituted by alternately juxtaposing a plurality of anion and cation exchange membranes between at least a pair of electrodes by supplying the electrolyte solution into the desalting and concentrating chambers while introducing a gas in a bubble state into the electrolyte solution between the ion exchange membranes, the electrolyte solution is made to contact the gas in the bubble state while providing a temperature difference between the gas and the electrolyte solution. The scale deposition onto the ion exchange membranes is prevented with an increase in electrodialysis efficiency.</p> |
