Abstract:
A method of using ozone for purification of water flowing through a vessel from an inlet nozzle to an outlet nozzle wherein the inlet nozzle is at a first elevation, comprising the steps of:a) injecting ozone into a stream of water to produce a first ozone concentration of ozonated water within the stream of water;b) introducing the stream of water into the vessel at a second elevation in the vessel between the inlet nozzle and the outlet nozzle to produce a second ozone concentration of ozonated water within the vessel, wherein the first ozone concentration is greater than the second ozone concentration; andc) supplying the stream of water using ozonated water which is extracted directly from the vessel at an elevation higher than either the first or second elevations and has an ozone concentration greater than the ozone concentration of the water entering the vessel through the inlet nozzle.
