Abstract: An apparatus for producing ozonated water including a container defining a chamber and having a first inlet for introducing purified water into the chamber, a second inlet for introducing vaporized ozone into the chamber, and an outlet for venting ozonated water from the chamber is disclosed. A pump siphons ozonated water from the chamber of the container via the outlet of the container. A suitable introducing assembly is also provided for introducing vaporized ozone into the chamber of the container through the second inlet. A sensor measures oxygen reduction potential (ORP) of the ozonated water, and controls the amount of the vaporized ozone introduced into the chamber of the container by the introducing assembly.

Abstract: A method for cleaning an article, such as a used kidney dialyzer, requiring sterilization includes the steps of manually rinsing the article with purified water, inserting the article into an automated reuse apparatus which utilizes ozonated water, and sterilizing the article for a predetermined period of time with ozonated water wherein the ozonated water flows through the article for sterilizing it. The step of inserting the article into the automated reuse apparatus includes the steps of rinsing the article with ozonated water, reversing the flow of ozonated water through the article for backwashing the article, and conducting testing cycles wherein the article is tested for leaks therein and for ensuring it can contain a predetermined quantity of fluid. Preferably, the predetermined period of time of the sterilizing step is approximately thirty minutes. An apparatus for producing ozonated water is further disclosed.
