Abstract: A fluid disinfection unit comprising a fluid treatment housing, an electrical supply module and electrical connection means connecting the fluid treatment housing and the electrical supply module;the fluid treatment housing comprising a fluid inlet and a fluid outlet in communication with a reaction chamber, an ultraviolet radiation lamp disposed in the reaction chamber and having a first electrical connection receiving means at a first end thereof and a second end thereof being closed, the second end of the ultraviolet radiation lamp being received and held in place by fixture means;the electrical supply module comprising ballast means and a second electrical connection receiving means; andthe electrical connection means comprising lamp receptacle connector means at one end thereof for removable connection to the ultraviolet radiation lamp and electrical connection receiving means for connection to the electrical supply module.

Abstract: A fluid treatment system and process includes structure and steps relating to a gravity fed fluid treatment system. A fluid inlet and a fluid outlet are provided, and an irradiation zone is disposed between the fluid inlet and the fluid outlet. The irradiation zone includes at least one radiation source and has a closed cross-section to confine fluid to be treated within a predefined maximum distance from the at least one radiation source. Cleaning structure is provided to remove undesired materials from an exterior of the radiation source. The cleaning structure comprises a cleaning sleeve surrounding the radiation source and movable with respect thereto. The cleaning solution includes a chamber surrounding and in contact with the exterior of the radiation source, the chamber being supplied with a cleaning solution suitable to remove undesired materials from the exterior of the radiation source.

Abstract: A fluid purification device including an inverted U-shape frame whose legs support a plurality of lamp assemblies each including an ultraviolet lamp received in a protective sleeve. One of the legs is hollow and receives lead wires connected to the lamps through openings spaced along the leg. The protective sleeves at one of their ends are resiliently mounted to the hollow leg at the openings, and seals are provided to prevent fluid from entering into the hollow leg and the protective sleeve. The other ends of the protective sleeves are closed and held in receptacles in the other frame leg which is formed by two plates fixed to each other. "O" rings provided along the other leg receive the protective sleeves to provide flexible seats. An electrical ballast controlling voltage and amperage at the lamps is incorporated in the frame.

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.
