Abstract
A method and apparatus for removing oxidizable contaminants in cooling waters used to extract heat from the condenser coils of cooling towers. The method and apparatus includes means for removing a portion of the recirculating water which passes through the cooling tower to create a slipstream of water to be treated and treating the slipstream water with chemical to provide a hydroxyl free radical into the water to enhance oxidation, inducing cavitation in the slipstream water and irradiating the slipstream water with ultraviolet radiation to thereby cause the oxidizable contaminants to be oxidized and therefore removed before the slipstream water is reintroduced back into the cooling tower.
