Ozone contact chamber

A method for contacting ozone and water, said method comprising:

• providing a contacting chamber for contacting ozone and water, said chamber having a central vertical axis and defining an enclosed space and having a top, a bottom, and at least one side wall, and further having an inlet and an outlet, wherein said inlet is within the top quarter of said enclosed space, said outlet is within 2 inches of said bottom,
• injecting an ozone and water mixture into said enclosed space through said inlet and tangential to said central axis to impart turbulence and a swirling motion that continuously agitates and churns said ozone and water contained within said enclosed space, and withdrawing a highly mixed ozone and water mixture via said outlet, wherein said ozone generally forms a laminar stratification within said enclosed space, with larger bubbles forming upper strata and progressively finer bubbles forming progressively lower layers, and wherein said inlet is elbowed after passing through the chamber top to provide a horizontal and tangential outlet into said contacting chamber to impart said turbulence and swirling motion.
