Control for UV water disinfection

摘要

A UV light source water disinfection system includes a UV light source that is driven or controlled by a ballast. Improved start-up scenarios are provided by use of a separate heating wire around the lamp or employing an inductive-coupled system to provide initial high power requirements. The UV lamp is discontinuously operated in order to extend the life of the system, save energy, and periodically dose standing water to prevent regeneration of undesired microorganisms.
