ELECTRODIALYTIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide an electrodialytic apparatus suppressed in the lowering of seal pressure under high temperature operation and stable over a long period time. SOLUTION: In the electrodialytic apparatus wherein ion exchange membranes are arranged between electrodes through chamber frames and clamping frames are arranged to both ends of the ion exchange membranes to clamp them to alternately form desalting chambers and concentration chambers, coned disc springs 4 are interposed between clamping frames 3 to clamp the clamping frames 3 by bolts l and ruts 2.
