FIELD: chemistry.
SUBSTANCE: invention relates to a method and an installation for removing ionised impurities from an electrolyte solution in an electromembrane device. The installation for treating an initial stream containing ionised substances comprises an electromembrane device with apparatus for supplying an initial stream to the device and a treated stream from the device, an anode, a cathode, electrolyte solution and apparatus for moving at least one stream of this electrolyte solution between the cathode and the anode, which are made with possibility of applying electrical current so as to initiate electro-deionisation in the electromembrane device to remove ionised substances from the initial stream into a concentrate; the said installation further includes apparatus for moving extracted ions from the electrolyte solution to the concentrate stream with application of such current.
EFFECT: invention enables removal of ionic impurities from an electrolyte without significant modification of existing equipment.
