Abstract
An ultraviolet wastewater or water treatment system is described and comprises a plurality of ultraviolet lamps where each lamp includes a protective cladding and where the ultraviolet lamps are disposed in vertical modules that form a bank of ultraviolet lamps. A series of beams are disposed over the ultraviolet lamps with each beam supporting a carriage thereon. Each carriage supports a scraper that extends downwardly therefrom for engaging and cleaning a module of ultraviolet lamps. A common drive source is operatively connected to the respective carriages for driving the carriages back and forth on the respective beams such that as the common drive source drives the carriages back and forth, the respective scrapers move back and forth cleaning the protective cladding extending around the respective ultraviolet lamps.
