Two-chamber electrodialysis cell with anion and cation exchange membrane for use as an anode in alkaline zinc electrolytes and zinc alloy electrolytes for the purpose of deposition of metal in electroplating systems

A two-chamber anodic system which is suitable for utilizing in a galvanic system comprising the two-chamber anode system and a cathode,

• the two-chamber anodic system containing an anodic substrate in combination with an alkaline zinc- or zinc alloy electrolyte for the deposition of zinc- or zinc alloy,
• wherein:
• the anodic substrate is separated from the alkaline zinc- or zinc alloy electrolyte by a cation- and an anion exchange membrane;
• the cation and anion exchange membranes form two separate anolyte chambers which are inner anolyte chamber and outer anolyte chamber;
• the inner anolyte chamber, where the anodic substrate is located, is flowable through by an anolyte;
• wherein the inner anolyte chamber has an inflow device through which the anolyte flow is directed to a foot of the anodic substrate;
• and
• the outer anolyte chamber has openings with inflow- and outflow devices to be filled with the anolyte;
• wherein the outer anolyte chamber surrounds the inner anolyte chamber;
• wherein the inner anolyte chamber and the outer anolyte chamber each has an inflow device and an outflow device;
• and
• wherein the inner anolyte chamber has an outlet flow device through which the ascending anolyte flow is conveyed into an outlet line, which opens into an anolyte reservoir, in a collecting line.
