Abstract
Abstract An ozonizer formed of a pair of tubular or plate-shaped carriers having respective electrodes arranged thereon, with the electrodes laying opposite to each other. A non-conductive layer is provided covering one of the electrodes. On the surface of the non-conductive layer facing the other electrode is provided an electrically conductive layer forming separate islands to form a discharge gap extending in the direction of the longitudinal axis of the ozonizer between the other electrode and the conductive layer forming the separate islands. The discharge gap contains a stream of an oxygenic gas or of pure oxygen.
