Water decontaminating device
First Claim
1. A sterilizing apparatus for sterilizing a fluid, said apparatus comprising:
- a) a first chamber having an inlet and outlet, for the containment and circulation of said fluid;
b) a second chamber sealingly isolated from the first chamber and having an inlet and outlet, for the containment of a gas stream;
c) a source of ionizing radiation adapted to expose said first and second chambers to ionizing radiation for the simultaneous production of ozone within said second chamber and an antimicrobial action on said fluid within said first chamber;
d) a gas conduit for conducting an oxygen-containing gas into said second chambers said gas conduit comprising first and second portions, said first portion being positioned within the first chamber, and comprising means for transferring heat from said gas to said fluid so as to cool said gas and condense moisture therefrom onto said conduit, said second portion being positioned within said second chamber adjacent said ionizing radiation source sufficiently close thereto to extract heat therefrom for the lowering of the relative humidity of said gas, said second portion terminating in said inlet into said second chamber.

Abstract
A sterilizing apparatus is provided to simultaneously generate ozone and expose a contaminated fluid to ionizing radiation, such as UV radiation, for the sterilization of water. The device includes an air supply conduit to circulate current of air through an ozonation chamber, with the conduit being routed through a water exposure chamber, wherein the air is cooled by the relatively lower temperature of the water at the same time as the water is being decontaminated by exposure to sterilizing radiation. The conduit continues into the air exposure chamber, where it is positioned adjacent the UV lamp to dry the air by the warmth generated by the lamp. The second part may comprise a metal tube having a helical portion coiled about an end region of a tubular UV lamp, and a straight portion positioned adjacent a middle region of the lamp, in order to accommodate the differential heat output of the lamp at the different regions thereof.
