Abstract

A cleaning apparatus for a radiation source assembly in a fluid treatment system is described. The cleaning system comprises: a cleaning sleeve comprising a cleaning ring for engagement with a portion of the exterior of the radiation source assembly; a slidable member magnetically coupled to the cleaning sleeve, the slidable member being disposed on and slidable with respect to a rodless cylinder; and motive means to translate the slidable member along the rodless cylinder whereby the 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 as when it becomes fouled.
