ELECTRODIALIZER Russian patent published in 1996 - IPC

FIELD: electrochemical machining of liquids-electrolytes by the method of electrodialysis, in particular, electrodializers of the filter-press type. SUBSTANCE: each spacer has a slot in the form of concentric area interconnected in succession; the length of the transition section makes up 2 to 10% of the arc length. The slot is made in the form of concentric ares so that the section area of each subsequent turn relates to the area of the previous one within 0.9 to 0.5. EFFECT: reduced power consumption and labour content of production of electrodializer, enhanced reliability of apparatus operation. 2 cl, 5 dwg
