Apparatus and method of purifying water with ozone
First Claim
Patent Images
1. A method for purifying a flow of water in a water flow line by use of an apparatus comprising(a) means for providing a flow of an ozone-containing gas;
- (b) means for introducing the flow of the ozone-containing gas into the flow of water;
(c) a mixing chamber for turbulent mixing of the ozone-containing gas with the flow of water, located on the water flow line in the vicinity of (d) an outlet for the flow of water; and
(e) electronic control means adapted to control the operation of said apparatus, thereby providing a flow of water which on exiting through the outlet for the water flow is essentially free from residual ozone and from contamination by Legionella bacteria wherein the ozone-containing gas is introduced into the flow of water so as to maintain (i) a concentration of ozone in the water within the mixing chamber of about 0.01-0.5 mg/l; and
(ii) a contact time between the ozone-containing gas and the water that is essentially equal to the time of continuous flow of the water flow from a water inlet of the mixing chamber to the outlet for the water.

Abstract
A method for purifying a flow of water, by eliminating any Legionella bacteria present therein using (a) an ozone generator, (b) an ozone injector for injecting ozone into the flow of water, (c) a mixing chamber for mixing the ozone with the flow of water; (d) an outlet for the flow of water, and (e) an electronic controller for the operation thereof: wherein the mixing chamber is of an inner geometry such as to create turbulence in the flow of water therein.
