UV dose investigation for imersed lamp purifier for electronic ballast UV lamps design

This paper presents a methodology of an electronic ballasts design for UV lamps filtering system, providing adjustable UV dose in order to ensure the inactivation of microorganisms´ reproduction that are harmful to human health and can be present in drinking water. The project methodology is based on a so called MSSS model, used for defining the ultraviolet radiation applied to penstock purifiers, using immersed lamps on a water slide enclosure, which in combination with the hydraulic behavior, provide a good perspective of the microorganisms UV absorption along the entire purifier ducts structure. In addition, a water purifier was designed using CAD model, where hydrostatic simulations were applied to ensure compliance with the NSF/ANSI Standard 55, which provides drinking water directions for commercial and residential environments.
