ABSTRACT:
An ultraviolet processing chamber for treating contaminated waste water and the like. The processing chamber includes a chamber body defining a passageway through which the water under treatment flows. An enclosed volume is defined which contains an array of linear UV lamps and which includes a protective wall formed of a material substantially transparent to UV radiation. The protective wall is disposed with respect to the flow passageway so as to permit UV radiation to pass in substantial amounts into the flow passageway to irradiate the water or other substance under treatment. For ease of maintenance the array of UV lamps is contained in a module which is removable from the remainder of the processing chamber. More specifically, the lamps are mounted on a base portion, which may be secured in position on the chamber, and the plurality of lamps forming the array extend into the enclosed volume separated from the substance under treatment by the protective wall. Another assembly receives the ends of the lamps opposite the base portion. The base portion and the receiving assembly are formed to be in flow communication with the enclosed volume to permit circulation of coolant about the lamps within the enclosed volume to cool the lamps. Disposed within the passageway are a plurality of flow diverters, which direct the water under treatemnt to peripheral regions of the chamber passageway and to regions of the passageway proximate to the enclosed volume of higher UV intensity.
