Abstract

An electrolysis device for the electrolytic treatment of liquids has an anode chamber and a cathode chamber which are separated from one another via an ion exchange membrane. The chambers are provided with an inlet opening and an outlet opening for the flowing electrolyte, each with one electrode. The inner space of the anode chamber and/or of the cathode chamber are/is subdivided by webs or ribs extending transversely with respect to the electrodes. The webs or ribs are provided at least regionally with holes or cut outs. The webs or ribs include at least one lower region free of holes or cut outs. The electrolysis device provides sufficient mixing in the upper foam phase in the longitudinal direction and also at the same time the airlift pump effect is maintained by way of ascending gas bubbles in the lower region.
