Abstract
In-situ cleaning of the bilgewater processing plates of stacks within the tank chamber of an oil/water separator is performed by an injected chemical cleaning agent while being dispersed by diverted flow of pressurized air introduced into the tank chamber below the plate stacks in the form of air bubbles emerging from plural branches of an air sparging array positioned in underlying alignment with crest formations of the processing plates.
