Abstract: A method and apparatus for purifying fluids with ozone and ultraviolet radiation. A housing defining an ozone creation chamber having a plurality of ultraviolet radiation sources disposed circumferentially around the inner surface of the housing is provided. Oxygen containing gas, such as ambient air, is directed to flow within the housing. An effluent conduit of ultraviolet radiation permeable material is disposed coaxially within the housing. A venturi is disposed within the effluent conduit. An ozone gas discharge conduit is connected between the ozone creation chamber and the venturi, such that ozonated gas generated within the ozone creation chamber is sucked into the effluent stream flowing within the effluent conduit, thereby purifying the fluid contained therein. The mixture of ozone and fluid passes out the outlet of the effluent conduit and into either a water supply, or is recirculated back through the apparatus for further processing.
