MULTI-SECTION ELECTRODIALYZER Russian patent published in 1999 - IPC

FIELD: electrochemical cleaning of water, mainly in radio engineering, electronic, food-processing industries and medicine; electrodialysis-type devices for deep desalinization of water. SUBSTANCE: cation selective and anion selective diaphragms and gaskets located between electrodes in multi-section electrodialyzer form closed system with even number of electrodes connected in turn to different poles of power supply source. Construction provides for gathering unlike ions of salts in different concentration chambers, thus excluding formation of insoluble salts and sedimentation of such salts on diaphragms. EFFECT: enhanced operational reliability at any amount of salts in initial water; ease in service. 5 cl, 3 dwg
