Abstract
A cleaning apparatus for a radiation source assembly in a fluid treatment system is described. The cleaning apparatus comprises: a carriage movable with respect to an exterior of the radiation source assembly; at least one cleaning sleeve in sliding engagement with the exterior of the radiation source assembly, the at least one cleaning sleeve being moveable with respect to the carriage; and drive means coupled to the carriage to translate the carriage whereby the at least one cleaning sleeve is translated over the exterior of the radiation source assembly. A radiation source module comprising the cleaning apparatus is also disclosed. The radiation source module is particularly useful for ultraviolet radiation of wastewater while having the advantages of in situ cleaning of the radiation source when it becomes fouled. Radiation source replacement is also facilitated.
