Abstract
The present invention relates to an apparatus for the production of ozone from water comprising at least one cell, consisting of an anode, a cathode and an interposed cation-conducting membrane, wherein the membrane conductively connects the anode and the cathode while forming flow channels for water that are separated from one another as anode and cathode chambers and wherein the flow channels are configured to allow for the recirculation of the water flow within the chambers. The present invention further relates to an electrochemical method and apparatus for producing ozone or dissolved ozone in water in high concentrations by mean of recirculation of water between at least one chamber and at least one water tank.
