Abstract
In a method of removing organic contaminants from a liquid, an oxidizing gas is formed into sub-micron size bubbles which are dispersed into an initially contaminated liquid, after which the treated liquid is recovered. The oxidizing gas is preferably selected from a group including ozone and chlorine dioxide and is utilized immediately upon its manufacture. An oxidizing liquid may be employed in conjunction with the oxidizing gas.
