PIOx technology utilizes short wave ultraviolet light (185nm) to convert oxygen to ozone.  Ozone reacts with organic material to convert it to carbon dioxide and water.  If the organic material is a bacterium or virus, it is not only killed but also oxidized.

Other components of organic material such as nitrogen are released as gaseous nitrogen.  The exposure of the organic contaminated water occurs within a pipe, which consists of a micro-porous tube contained within an air plenum.  The contaminated water is injected tangentially to the edge of the tube so that the water forms a thin film on the inside surface of the gas porous tube.  The film follows a ribbon type pattern around and down the surface of the tube.  As the water swirls, air is injected through the gas porous tube and becomes entrained in the water forming a froth containing billions of microbubbles.

The UV lamp is located in the core of the tube and emits the short wave photons into the froth.  As the short wave photons radiate the oxygen within the bubbles, the oxygen converts to ozone or nascent oxygen, which then reacts with organic matter converting it to carbon dioxide and water .  As there is a significant centrifugal force field created by the swirling water, the carbon dioxide and nitrogen move to the the core of the tube and then vertically to the exit port located at the top of the chamber.  The treated water exits the tube through the lower end of the tube (opposite of the water entry and electrical connections for the lamp).  This water is collected in a container for subsequent reuse or discharge.
