Abstract: An ozone generation cell operating by corona discharge in an annular passage with regions of corona discharge alternating with corona-free regions where cooling takes place is improved by the incorporation of corrugated, deformable heat transfer walls in the corona-free regions. These corrugated walls impart flexibility to the structure, and thereby relieve the strain on the structural components. This permits the heat transfer wall, which is the outer of the two cylinders defining the annular passage, to center the inner of the two cylinders inside it and thus achieve a more uniform gap width in the corona regions. This is of value since the inner cylinder is preferably made of a ceramic material and not perfectly straight. The corrugations also promote turbulent flow in both the coolant medium and the gas mixture in which the ozone is generated.

Abstract: Ozone is added to captured water by a method and apparatus which involves corona discharge into an oxygen-containing gas in regions in a generator which alternate with regions where the newly formed ozone is cooled. The alternating corona and cooling regions permit the ozone to form without being thermally decomposed as soon as it is formed. Also disclosed is an overall system and method of controlling the level of dissolved ozone in a body of captured water which modulates the output of an ozone generator in accordance with readings of oxidation-reduction potential in the water.
