An electrolysis device, for producing alkaline water from water, includes an electrolysis vessel, a pair of high porous electrodes arranged in the electrolysis vessel, and a cell unit arranged between the positive and negative electrodes. The pair of high porous electrodes respectively serve as a positive electrode and a negative electrode. The cell unit includes a bipolar membrane element and at least one cation exchangeable membrane. The bipolar membrane element has a cation exchangeable side and an anion exchangeable side. The cation exchangeable side is closer to the negative electrode than the anion exchangeable side. The cation exchangeable membrane is arranged between the anion exchangeable side of the bipolar membrane element and the positive electrode, so as to define an alkalic chamber between the bipolar membrane element and the cation exchangeable membrane.

The present invention relates to an ionic species removal system comprising one or more electrode stack(s), each electrode stack including two electrodes and cation exchange membranes and anion exchange membranes alternately arranged between the two electrodes, wherein at least one electrode of at least one of the electrode stack(s) is an electrode coated with an ion exchange coating. The ionic species removal system mitigates the scaling risk by employing an electrode coated with an ion exchange coating.
