Patent attributes
An apparatus for treating fluid in a main reservoir includes an auxiliary reservoir and filter located outside the main reservoir. Ozonated air bubbles are injected by a diffuser into a lift tube containing fluid from the main reservoir. The fluid flows up the lift tube and into the auxiliary reservoir due to the expansion of the ozonated air bubbles as they go up the lift tube. The fluid is caused to pass through the auxiliary reservoir and filter and back into the main reservoir as a result of the flow of ozonated air in the lift tube. A UV germicidal lamp is positioned in the path of fluid flow downstream of said diffuser. In an alternate embodiment, fluid flow to and from the main reservoir is via conduits normally used to connect the main reservoir to a conventional high pressure water pump and filter.
