| 20130341286 | OZONE-ASSISTED FLUID TREATMENT METHOD - The invention is a method for treating fluid in a main fluid reservoir, e.g., a pool, spa, or water tank, etc., using ozonated air. A fluid filter is placed in an auxiliary fluid reservoir located in or next to the main fluid reservoir. An ozone generator pumps a combination of ozone and air into the auxiliary reservoir. Fluid in the auxiliary reservoir passes through a filter and back into the main reservoir without the use of any fluid pump. More specifically, a vertical lift tube is placed beneath the auxiliary fluid reservoir so that the open top of the lift tube is within the auxiliary reservoir. Fluid from the main reservoir is fed to the bottom of the lift tube. Ozone and air from the ozone generator is also piped into the lift tube near its bottom. The fluid flows through the filter due to the effect of ozone and air bubbles released by a diffuser at the bottom of the lift tube. The diffuser releases thousands of tiny bubbles into the lift tube, which cause the fluid in the tube to rise and mix with fluid already in the auxiliary fluid reservoir. This rising fluid also causes fluid to flow through the filter. The ozone treated fluid output from the filter is piped back into the main fluid reservoir. | 12-26-2013 |
