ELECTRODIALYSIS PLANT Russian patent published in 1997 - IPC

FIELD: equipment for demineralization and concentration of solutions. SUBSTANCE: electrodialysis plant has electrodialyzers with inlet branch pipes and two groups of outlet branch pipes, three collectors made as closed circuits, tank of initial water connected to first collector through pump, chains of first and second groups outlet branch pipes connection to second and third collectors correspondingly. Introduction of gate valves in chains of connection of one of groups outlet branch pipes and connection of all inlet branch pipes of electrodialyzers to first collector allows to exercise concentration or demineralization of solutions till given concentration of mineral salts without their circulation and using only one pump and so allows to increase correspondingly operational reliability of plant. EFFECT: simplified structure of electrodialysis plant and process of its operation, increased reliability of plant. 2 cl, 1 dwg
