Abstract: An ozone purification system for wastewater comprising an ozone diffusion reactor installable in or in fluid communication with wastewater collection tanks of septic or other wastewater systems. The reactor includes a pump that circulates wastewater through a gas-liquid mixing device, a contact volume, and a static mixer. The contact volume comprises an elongate length of contact piping and the static mixing chamber is configured to impart turbulence into the flow of the circulated wastewater and ozone gas.

Abstract: A distributed ozone disinfection system has a central ozone generation system, and ozone and water mixing systems. Each of the ozone and water mixing systems is positionable in a water supply piping at a water supply inlet for a sink faucets or water outlets. The distributed ozone disinfection system has vacuum switches, separate from vacuum switches positionable downstream which are in turn separate from the ozone and water mixing systems, and a plurality of oxidation reduction potential (ORPs) meters. The ORP meters are positionable downstream and separate from the ozone and water mixing systems. Optionally, the ozone and water mixing system includes a vacuum switch coupled with a gas injection venturi device.
