There is disclosed a coupling for a radiation source assembly that comprises an elongate radiation source and an elongate radiation transparent protective sleeve for receiving the elongate radiation source. The coupling disengages in two stages when it is desired to remove the elongate radiation source for servicing (or any other purpose). The coupling is disengaged from a first position in which a seal is made between the sleeve bolt element and the lamp plug element. When this action takes place, the lamp plug element is still secure with respect to the sleeve bolt element but since there is no seal between the two, any fluid which has flooded the elongate radiation source (e.g., due to breakage or other damage to the protective sleeve) will emerge from the coupling warning the operator not to fully disengage the lamp plug element from the sleeve bolt element. If no such fluid is seen by operator, the operator may continue to disengage the lamp plug element from the sleeve bolt element to withdraw the elongate radiation source from the elongate radiation transparent protective sleeve.

Radiation source assembly

There is disclosed a cleaning apparatus for a radiation source assembly in a fluid treatment system. The clean apparatus comprises a cleaning sleeve moveable to remove fouling materials from an exterior portion of the radiation source assembly, the cleaning sleeve comprising at least one chamber for receiving a cleaning fluid and a cleaning sleeve inlet in fluid communication with the at least one chamber and a first conduit element for conveying the cleaning fluid to the cleaning sleeve inlet, the first conduit element being configured such that a distal portion of the first conduit element is in fluid communication with the cleaning sleeve inlet and a proximal portion of the first conduit element is disposed outside of fluid being treated in the fluid treatment system.

Cleaning apparatus, radiation source module and fluid treatment system

There is described a radiation source module for use in a fluid treatment system. The radiation source module comprises: a housing having an inlet, an outlet and a fluid treatment zone disposed between. The fluid treatment zone comprises a first wall surface and a second wall surface interconnected by a floor surface. The first wall surface, the second wall surface and the floor surface are configured to receive a flow of fluid through the fluid treatment zone. The radiation source module further comprises at least one radiation source assembly secured with respect to the first wall surface and the second wall surface and a module motive coupling element connected to the housing and configured to be coupled to a module motive element to permit the radiation source module to be installed in and extracted from the fluid treatment system. A fluid treatment system comprising the radiation source module is also described.

Radiation source module and fluid treatment system

There is described In another of its aspects, the present invention provides a radiation source assembly comprising: (i) an elongate radiation source; (ii) a positioning element connected to a proximal portion of the elongate radiation source; and (iii) a connecting portion secured to a proximal portion of the positioning element and configured to engage a support element to maintain a distal portion of the elongate radiation source in a cantilevered position. The present radiation source assembly is configured such that the distal portion of the radiation source is cantilevered with the respect to the distal portion of the protective sleeve in which it is disposed. This feature obviates the need to use spacers, stops, springs and the like in a distal portion of the protective sleeve to maintain correct position of the radiation source within the protective sleeve. Further, the present radiation source assembly is advantageous in that allows for withdrawal of the radiation source from the radiation source assembly without the need to disengage all of the components. Thus, it is possible to replace a single radiation source by removing it from the protective sleeve during operation of the fluid treatment system. This operation can be accomplished quickly without the need to shut down the fluid treatment system or otherwise compensate for the fact that one of the radiation source is being serviced.

In one of its aspects, the present invention relates to a fluid treatment system comprising: an inlet; an outlet; a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone: (i) comprises a first wall surface and a second wall surface opposed to the first wall surface, and (ii) having disposed therein at least one array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis transverse to a direction of fluid flow through the fluid treatment zone and each of the first wall surface and the second wall surface comprises a first fluid deflector element and a second fluid deflector element. The first fluid deflector element projecting into the fluid treatment zone to a greater extent than the second fluid deflector element.

Fluid treatment system

There is described a fluid treatment system. The fluid treatment system comprises: an open channel for receiving a flow of fluid and a fluid treatment zone. The fluid treatment zone comprising a plurality of elongate radiation source assemblies orientated such that: (i) a longitudinal axis of each radiation source assembly is transverse to a direction of fluid flow through the fluid treatment zone, and (ii) an end of each radiation source assembly is disposed above a predetermined maximum height of fluid flow in the open channel. A first baffle plate is disposed upstream of the fluid treatment zone. The first baffle plate is positioned such that a distal end thereof is below the predetermined maximum height of fluid flow in the open channel. In a preferred embodiment, the present fluid treatment system provides for an area in which a cleaning system for the radiation source assemblies can be 'parked' when not in use. In the so-called 'parked' position, the cleaning system may be readily accessed for servicing and the like without affecting the flow of fluid through the fluid treatment zone and a fluid treatment system. This is as significant advantage of the fluid treatment system.

There is disclosed an elongate radiation source cartridge. The cartridge comprises: (i) an elongate radiation source assembly having a proximal portion and distal portion, the distal portion of the elongate radiation source assembly being unsupported, (ii) a housing coupled to the proximal portion of the elongate radiation source assembly, and (iii) a power supply disposed within the housing, the power supply in electrical communication with the elongate radiation source assembly (in certain embodiments the power supply is optional). The elongate radiation source assembly and the housing are in substantial alignment with respect to a longitudinal axis of the elongate radiation source cartridge.

Radiation source cartridge and module containing same

There is described a fluid treatment system comprising an array of independent fluid treatment reactors. The reactors are arranged in a manner whereby a flow of fluid may be passed through the array in a substantially helical direction. The fluid treatment system is capable of treating large volumes of fluid (e.g., water) while requiring a relatively small foot print. In essence, the present fluid treatment system concentrates a relatively large number of radiation sources in a relatively small amount of space resulting in the ability to treat large volumes of fluid (e.g., water).

A fluid treatment device, preferably for the treatment of water, is described. The device comprises a closed housing having a fluid inlet, a fluid outlet and a fluid treatment zone disposed between the fluid inlet and the fluid outlet. The fluid treatment zone comprises a first irradiation zone and a second irradiation zone. At least one fluid mixing element is interposed between the first irradiation zone and the second irradiation zone.

Fluid treatment device

A cleaning apparatus () for a radiation source assembly () in a fluid treatment system is described. The cleaning apparatus comprise cleaning chamber () and a second chamber () independent of the cleaning chamber which defines a fluid (typically water) buffer layer to obviate or mitigate cleaning fluid from the cleaning chamber leaking into the fluid being treated. The fluid treatment system is particularly useful for us in clean water applications in which ultraviolet radiation is used to treat the water while having the advantages of in situ cleaning of the radiation source when it becomes fouled.

Fluid treatment system and cleaning apparatus therefor

A cleaning apparatus for use in a fluid treatment system comprising a radiation source assembly, the cleaning apparatus comprising: at least one cleaning sleeve ( ) in sliding engagement with the exterior of the radiation source assembly ( ); a cleaning chamber ( ) disposed in the at least one cleaning sleeve in contact with a portion of the exterior of the radiation source assembly ( ) and for being supplied with a cleaning solution, the cleaning chamber comprising an opening ( ) to an exterior of the cleaning sleeve; a pressure equalization member ( ) disposed in the opening to provide a seal between the opening and the exterior of the cleaning sleeve, the pressure equalization member being movable in response to a pressure gradient thereacross; and drive means to translate the at least one cleaning sleeve along the exterior of the radiation source assembly.
