Claim Text:
1. An ozone diffusion reactor positionable within a wastewater collection tank having a volume of wastewater contained therein, the reactor comprising an elongate enclosure having a top end and a bottom end with a wall extending there between forming a hollow chamber, wherein the top end of the enclosure is enclosed and the bottom end includes a plurality of openings in the wall positioned about a periphery of the enclosure adjacent the bottom end of the wall of the enclosure, the plurality of openings fluidly communicating with the hollow chamber to allow wastewater to enter the chamber upon submerging the enclosure into a volume of wastewater contained within a wastewater collection tank, the wall of the enclosure having an interior surface and an exterior surface, a liquid-gas mixing device positioned within the chamber and configured to inject ozone into wastewater flowing through the liquid-gas mixing device, the liquid-gas mixing device having an inlet, an outlet and an ozone injection port positioned between the inlet and outlet, a contact volume positioned within the chamber and interconnected to the outlet of the liquid-gas mixing device, wherein the contact volume comprises an elongate length of contact piping extending one or more turns about a perimeter of the chamber along the interior surface of the wall, wherein the contact volume includes a turbulence imparting interior surface to impart turbulence to a mixture of wastewater and ozone gas as the mixture of wastewater and ozone flows through the contact volume, a static mixing chamber coupled to the contact volume and positioned within the chamber, the static mixing chamber configured to impart turbulence to the mixture of wastewater and ozone gas as the mixture of wastewater and ozone flows through the static mixing chamber, and a pump positioned within the chamber and interconnected to the liquid-gas mixing device, when the enclosure is at least partially submerged in a volume of wastewater, the pump being configured to draw wastewater from the volume of wastewater within the chamber external to the liquid-gas mixing device, contact volume and static mixing chamber and entered through the plurality of openings in the wall, and pump the wastewater through liquid gas mixing device, contact volume and static mixing chamber and back into the volume of waste water.
