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.
