  • Pressure-less ozonated di-water (DIO) recirculation reclaim system
    Patent number: 9796603
    Abstract: The invention provides, in one aspect, a system for recirculating ozonated liquid. The system includes a contactor including at least two inlets and at least two outlets. The contactor is in fluid communication with a first liquid source at a first contactor inlet and a second liquid source at a second contactor inlet, and the second contactor inlet receives gas that purges at least a portion of gas from liquid received at the first contactor inlet. The purged gas exits the contactor at a first contactor outlet. The contactor is in fluid communication with the second liquid source at a second contactor outlet, and the contactor drains at least a portion of the liquid in the contactor, the drained liquid exiting the contactor at the second contactor outlet. The contactor includes a third inlet in fluid communication with the first liquid source, the third inlet allowing the first liquid source to release liquid at an ambient pressure.
