Abstract

Abstract A method of disinfecting waste water wherein ultraviolet light producing lamps are positioned in lamp modules and contained within quartz lamps jackets and wherein the modules are positioned within a flow of water including removing particulates and films for the lamp jackets wherein one or more of the modules from the flow are removed, transported and inserted into a tank containing a lamp jacket cleaning agent. The invention further includes a cleaning system for removing particulates and films from lamp jackets consisting of a channel through which waste water to be cleaned passes, one or more modules positioned in the channel, the modules containing one or more ultraviolet light producing lamps, each lamp sealed from direct contact with the water by surrounding quartz jackets, the lamps being spaced apart to permit the water to flow there between to expose the water and ultraviolet light rays. The system further includes channel sealing walls positionable inside the channel to isolate the modules from the water and a cleaning agent positionable inside the isolated portion of the channel to clean the modules.
