FIELD: separation of chemical compositions. SUBSTANCE: electric dialyzer has base formed as parallelepiped with protrusions and recesses disposed in alternation on its surface, two side covers with electrodes, two slabs with working medium supply and discharge channels and packs located in base recesses and having frames, curved ion-selective membrane of first type, made continuous within one pack, and flat membranes of second type arranged in alternation with first-type membranes. Feeders are formed as depressions in frames and ridges of base having trapezium-shaped. Tubes are disposed in fan-shaped arrangement in depressions and covered by plates, which completely overlap depressions and are positioned in flush with frame and ridge surfaces. Electric dialyzer provides simplified assembling and maintenance, because it has minimum number of parts, simple and adaptable to manufacture. Assembling of dialyzer is effectuated] by inserting packs with membranes into base recesses. Chambers are pressurized by applying slight tightening force. EFFECT: simplified constructions, easy maintenance and replacement of membrane, which is contaminated or out of service. 4 dwg
