User-activated ultra-violet water treatment unit

摘要

A time delay in de-energizing the electronic ballast and its associated UV lamp subsequent to cessation of water discharge from a user-activated water treatment unit ensures irradiation of the water prior to a subsequent user-activated water discharge and reduces the likelihood of any live microorganisms being present in the water subsequently discharged. A soft start of the UV lamp upon actuation of the water treatment unit reduces the mechanical stresses imposed upon the filaments of the UV lamp and the life span of the UV lamp is enhanced.
