Abstract
For ultraviolet purification or sterilization of fluids, particularly waste water, lamp sections, each composed of opposed pairs of fluid impermeable light unit receiving sockets and lamp units therebetween are provided. Each lamp section consists of an inner, elongate, cylindrical ultraviolet ray emitting lamp and an outer, coaxial and substantially co-extensive cylindrical sleeve, arranged in parallel rows. Due to its immersion capability, the array of rows of lamps can be fluid immersed in either an open or closed system. Moreover, lamp withdrawal, fluid impermeable closure means is provided on at least one of each pair of sockets to facilitate lamp withdrawal in the event of burnout. Each row of lamps can also be modularized to facilitate easy removal of a malfunctioning row of lamps without having to shut down or remove the entire device from its fluid environment.
