Abstract
A system and method is provided for utilizing ultraviolet light to disinfect water. The system includes a plurality of ultraviolet lights with each ultraviolet light including a sheath that is transparent to ultraviolet radiation. Mounted adjacent the ultraviolet lights is a drive that moves back and forth with respect to the ultraviolet lights. Operatively interconnected with the drive is a support structure that includes a plurality of bearing rings. Inserted and held within each bearing ring is a scraping ring that in turn surrounds a respective sheath of an ultraviolet light. Actuation of the drive results in the support structure moving back and forth with respect to the ultraviolet lights and results in the scraping ring scraping and cleaning the respective sheaths.

30. A method of supporting and driving one or more scraping rings around one or more sheaths of ultraviolet lights that form a part of an ultraviolet water disinfection system, comprising:
-
a. supporting one or more scraping rings in a support structure having one or more bearing rings that form a part thereof; b. securing each supporting ring within a respective bearing ring of the support structure; and c. interconnecting the support structure with a drive such that the actuation of the drive causes the support structure to move back and forth and causes the scraping rings supported therein to move back and forth and scrape clean the one or more sheaths. - View Dependent Claims (31, 32, 33)
