Pilot module for electrodialysis - metathesis protected against shunt currents
Original language description
Electrodialysis – metathesis is electromembrane process working with two diluting and two concentrating streams. Cations from the first diluate combine with anions from the second diluate and form the first concentrate stream, and, vice versa, cations from the second diluate combine with anions from the first diluate and form the second concentrate stream. It is desirable to produce salts with as high concentration as possible. Large concentration differences between streams and diluate conductivity lower than conductivity of ion-exchange membranes are main causes of shunt current appearance in electrodialysis. Shunt currents decrease current efficiency and may lead to module damage usually called “module burning”. In pilot module for electrodialysis – metathesis, a part of ion exchange membrane around distribution channels was replaced by electrically non conductive insert. Moreover, spacers were covered by thin plastic film in order to completely insulate distribution system of liquid from membranes.
