First Claim
1. An ozone/water mixing apparatus comprising:
- a separating vessel structured to contain and degas an ozone/aqueous mixture, the separating vessel includingan off-gas outlet placed and structured to vent undissolved ozone gas from the separating vessel, andan ozonated water outlet placed and structured to pass the ozone/aqueous mixture from the separating vessel to an application for use; and
a mixing tower, extending into the separating vessel, the mixing tower includingan inlet portion structured to receive an ozone/aqueous stream, the inlet portion including a first inlet structured to receive an aqueous stream and a second inlet structured to receive a gaseous stream containing ozone, and an ozone injector connected to the first inlet and the second inlet, andan outlet portion structured to pass the ozone/aqueous mixture into the separating vessel.

Abstract
An apparatus and system for mixing and separating ozonated water is provided. The apparatus is especially useful as a component of a system for cycling sanitizing ozonated water to a body of water such as a pool, spa or pond. The apparatus generally includes a separating vessel including a mixing tower, preferably located substantially entirely within the separating vessel and including a diffuser element for enhancing mixing of ozonated water without increasing turbulence in the separating vessel. Preferably, the apparatus includes a seal mechanism that substantially prevents liquid water from escaping the separating vessel with vented off-gas. The invention further provides an ozone destruct assembly including a condensate collection portion, and may also include a return line for passing a treated off-gas into the body of water.
