| 摘要 |
The invention relates to an electrodialysis process, especially for seawater desalination, in which a liquid to be dialysed, especially seawater, is taken to an electrodialysis device (5) of an electrodialysis plant (1) and exposed therein to a d.c. voltage applied between an anode (27) and a cathode (28). In order to obtain a continuous process in which no hardening salts are deposited in the electrodialysis device (5), no metal coating forms on the cathode and the exchange diaphragms are not attacked by halogen gases, according to the invention a separate stream of liquid, especially a partial stream of the process, passes through the anode (27) and/or the cathode (28) and the electrodes are separated from the liquid by a diaphragm unit. |
