Abstract: A housing surrounds an elongated ultraviolet lamp and forms therewith a closed annular space to confine fluid passage means for fluids to be irradiated. The passage means surrounds the ultraviolet lamp and has relatively thin flattened passage runs that either encircle the lamp or extend longitudinally of the lamp. The passage means may provide a plurality of separate paths for sterilization of a plurality of fluid streams to be treated simultaneously and different fluid streams may be treated primarily by different wave lengths. The passage runs may be formed by thin walled resilient plastic tubing which may expand under internal fluid pressure into intimate contact with the lamp. The rays directed outwardly through the thin fluid streams may be reflected back through the thin fluid streams for greater irradiation efficiency.

Abstract: The invention relates to a device for sterilising a fluid flowing therethrough, said device comprising: a container having an inlet for receiving the fluid and having an outlet for discharging the fluid from the container; a body having a surface which is at least in part curved, the body being positioned within the container in such a way that the fluid flowing into the container via the inlet washes over or around at least part of said body at least in the region of its surface that is curved. The device also comprises a plurality of LEDs which are each designed to emit light having wavelengths in the range of UV radiation, preferably UV-C radiation. The LEDs are designed to irradiate the fluid washing over or around the curved surface of the body with the UV radiation of the LEDs.

Abstract: A device for disinfecting a fluid includes a first casing and a second casing. Each casing includes at least one source of UV radiation. A fluid passage is provided between the first casing and the second casing. The UV radiation emitted from the at least one source of UV radiation of the first casing is emitted in a first direction toward the fluid passage. The UV radiation emitted from the at least one source of UV radiation of the second casing is emitted in a second direction toward the fluid passage. The first direction is different than the second direction.

Abstract: A swimming pool water sanitizing unit with an ozone generator and a separate ultraviolet (UV) reactor chamber within the same housing unit. The ozone generator may include a water jacket gap between the ozone generator chamber and the outer casing that passes pool water through the gap for cooling. Either of the ozone generator and the UV reactor chamber may include UV intensity sensors to help predict the life of the UV bulb therein. The UV reactor chamber may include rotating water paddle blades to stir up the water within the chamber for enhanced exposure to the UV light. A diverter valve enables diversion of ozone enriched fluid to the pool pump in addition to the UV reactor chamber.

Abstract: UV apparatus comprises a tube (1) of UV transparent material, at least one UV lamp (5) provided externally of the tube so as to emit UV light towards the tube, and a core (3) extending in an axial direction within the tube and configured to create turbulent flow in a liquid passing through the tube. A photocatalyst is provided on at least one surface of the core and is responsive to UV light emitted by the lamp to generate free radicals in liquid passing through the tube.

Abstract: An apparatus for treating a contaminated fluid has a UV lamp within a tubular housing. A plurality of baffles within the housing create meandering pathways parallel to the lamp for exposing the fluid to the UV light along the entire length of the pathways. A photocatalytic coating on the baffles and inner surfaces of the housing is maintained within a pre-set radial distance, preferably no more than about 75 mm, from the lamp for optimal creation of a photocatalytic reactant. The contaminated fluid flowing through the meandering pathways is maintained in close proximity to the lamp and has adequate time for exposure to the ultraviolet light and photocatalytic reactant for treatment before exiting the housing. The baffles are removably positioned within the housing for convenient maintenance or to alter the length of the pathways, without re-sizing the housing. This apparatus is considered an affordable and compact environmental protection device capable of “redefining pollution control” by potentially mitigating close to 100% of harmful bacteria and toxic compounds.

Abstract: The present disclosure relates generally to systems and methods for determining the absorption coefficient and the optical density of a fluid as they relate to the wavelength of incident radiation. Specifically, ultraviolet light-emitting diodes (UV LEDs) or the like that emit ultraviolet (UV) radiation or the like are used as sources for irradiating the interior of an integrating chamber that is designed to increase the path length of the radiation through the fluid, thus enhancing the detection limits of the absorption coefficient and the optical density according to Beer's Law.
