Abstract

PURPOSE: To prevent yield reduction due to concn. penetration, in an electrodialytic apparatus having plural concentrating chambers and desalting chambers, by passing water to be treated through the concentrating chambers in a specific order to reduce the difference of concn. between the concentrating chambers and the desalting chambers.
CONSTITUTION: An electrodialytic apparatus is constituted by opposedly arranging a concentrating chamber 10 and a desalting chamber 20 so as to interpose an ion exchange film 1 therebetween. The concentrating chamber 10 is divided into small chambers 11W16 and, on the other hand, the desalting chamber 20 is divided into small chambers 21W26. In the desalting chamber 20, sea water is supplied to the small chamber 21 to be successively passed through small chambers 22W26 in series and, on the other hand, in the concentrating chamber 10, sea water is supplied to the small chamber 13 to be successively passed through small chambers 14W16 and thereafter through small chambers 11, 12. By carrying out the aforesaid operation, the difference of the concn. A of the concentrating chamber and the concn. B of the desalting chamber can be reduced extremely compared to a conventional example C.
