Abstract: A fluid treatment device comprising a housing for receiving a flow of fluid, the housing comprising a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, and at least one radiation source module disposed in the fluid treatment zone, the at least one radiation source module comprising a radiation source sealably connected to a leg, the leg sealably mounted to the housing, the radiation source being disposed substantially parallel to the flow of fluid. A method of treating a fluid in a housing comprising a fluid inlet, a fluid outlet, a fluid treatment zone disposed between the fluid inlet and the fluid outlet, the fluid treatment zone having at least one radiation source disposed therein is also described. The method comprises the steps of: (i) providing a flow of the fluid to the fluid inlet; (ii) feeding the flow of fluid from the fluid inlet to the fluid treatment zone in a manner substantially parallel to the at least one radiation source; (iii) irradiating the flow of fluid in the fluid treatment zone; and (iv) feeding the flow of fluid to the fluid outlet. During the method, the flow of fluid through the fluid inlet, the fluid outlet and the fluid treatment zone is substantially collinear. The fluid treatment device and method are ideally suited (but not limited) to inactivate microorganisms present in water.

Abstract: The invention relates to a cleaning apparatus for a radiation source assembly in a fluid treatment system. The invention is characterized in that the cleaning apparatus comprises: a cleaning sleeve engaging a portion of the exterior of a radiation source in the radiation source assembly and movable between: (i) a retracted position wherein a portion of the radiation source is exposed to a flow of fluid to be treated, and (ii) an extended position wherein the portion of the radiation source is completely or partially covered by the cleaning sleeve, the cleaning sleeve further comprising a chamber in contact with the portion of the radiation source, the chamber adapted for receiving a cleaning fluid suitable to remove undesired materials from the portion of the radiation source upon movement of the cleaning sleeve.

Abstract: A fluid treatment system includes one or more radiation sources arranged in an irradiation zone within a treatment zone through which fluid to be treated passes and is irradiated. The irradiation zone has a closed cross-section to maintain the fluid within a predefined maximum distance from tree radiation source. Preferably, the irradiation zone comprises a reduced cross-sectional area perpendicular to the direction of fluid flow and thus the fluid flew velocity is increased through the irradiation zone. This allows the fluid to enter the treatment zone at relatively low speed, traverse the irradiation zone at high speed and exit the treatment zone again at relatively law speed to minimize the loss of hydraulic head throughout the system. Fluid entering the treatment zone passes through an inlet transition region wherein the cross-sectional area is reduced prior to entering the irradiation zone and fluid eating the irradiation zone passes through an outlet transition region wherein the cross-sectional area is increased. Each transition region is designed to reduce hydraulic head losses as the fluid flow velocity is increased and decreased. In the irradiation zone, radiation sources are mounted on radiation modules which are arranged to provide improved accessibility for maintenance. The radiation modules may also be provided with cleaning assemblies which are operable to remove materials fouling the radiation sources in situ while the radiation sources are in the irradiation zone.
