Abstract: An aqueous electrolyte ozone generating system includes on electrolyte tank and liquid-vapor separator tank. Electrolyte tank has a liquid supply port located at its upper part which allows ozone gas-containing liquid (generated at an anode) to be supplied to the liquid vapor separator tank. Water at the bottom part of an separator tank flows back to the anode chamber of the electrolyte tank through a return port, and fresh water is replenished to the system simultaneously while the temperature of the water in the separator tank is controlled. Liquid-vapor separator tank is thin in horizontal width and long in the vertical direction. A heat exchanger wall is installed to and covers most of the surface area of at least one side of the separator tank. A temperature control, capable of providing a cooling effect, is integrally installed to the heat exchanger wall.

Abstract: An apparatus for producing ozone water by accelerated mixing and dissolving of ozone into water due to an enhanced contact efficiency of ozone gas and water with controlled temperature includes a circulation line for circulating ozone water and employs a jet nozzle (4) in a conduit (4) which returns the ozone water from the circulation line into a primary container. This causes negative pressure about the outlet of the nozzle, whereby the ozone gas is sucked into the water which is jetted. Thus, the ozone gas is rapidly mixed and dissolved into the water. Efficiency of stirring of the ozone water is also enhanced. A secondary container is provided in the circulation line, which specially facilitates cooling of the ozone water as well as prevention of freezing.
