Method and apparatus for ozone generation and treatment of water
First Claim
1. A method of generating ozone comprising the steps of:
- applying an AC voltage between a pair of electrodes to generate an electric field of the same frequency as the applied voltage;
providing a body of liquid with a free surface disposed opposite one of said electrodes;
spacing said one electrode from said free surface so that the electric field forms a multitude of Taylor cones at the free surface; and
passing of gaseous stream containing oxygen between said one electrode and said free surface to oxidise said oxygen upon corona discharge from said cones.

Abstract
A water treatment apparatus is provided in which the ozone generation and the water treatment may take place simultaneously. The ozone is generated from a continuous supply of air and/or oxygen at the surface of a running water by means of a high voltage electrode placed in the air or in oxygen at some distance above the water surface. The strong electric field between the high voltage electrode and the surface of the electrically grounded water stream generates a multitude of small Taylor cones at the surface of the water. Each Taylor cone goes into corona and in the process it generates the ozone. As the ozone is generated at the water surface, a substantial amount of ozone is immediately dissolved in water and the ozone that diffuses in the air continues to be in contact with the water surface. The undissolved ozone may be percolated through the same water for an additional primary or secondary ozonation.

- 15. An ozone generator comprising a body of liquid having a free surface, pair of electrodes one of which is spaced from and overlying said free surface and an alternating high voltage potential connected between said electrodes to impress an alternating electric field at said free surface, said field generating Taylor cones at said free surface and corona currents from the tips thereof to convert oxygen between said free surface into ozone.
