Abstract

Electrodialysis is a multistage unit with anode, cathode and a number of bipolar electrodes between them. The bipolar electrodes are preferably and are e.g. of graphite, and stages are connected by low impedance ionic bridges. The concn. of OH ions in unit is minimised, preventing precipitation of solids during process.
