Abstract: There is disclosed an optical radiation sensor system for detecting radiation from a radiation source. The system comprises: a housing having a distal portion for receiving radiation from the radiation source and a proximal portion; a sensor element in communication with the proximal portion, the sensor element configured to detect and respond to incident radiation received from the radiation source; and motive means configured to move the housing with respect to the sensor element between at least a first position and a second position. A radiation pathway is defined between the radiation source and the sensor element when the housing is in at least one of the first position and the second position. Movement of the housing with respect to the sensor element causes a modification of intensity of radiation impinging on the sensor element. In its highly preferred embodiment, the radiation sensor system is of a modular design rendering the sensor system appropriate for use with one or more of various radiation sources, fluid thickness layers and/or in UVT conditions. In this highly preferred form, the sensor system may have built-in diagnostics for parameters such as sensor operation, radiation source output, fluid (e.g., water) UVT, radiation source fouling (e.g., fouling of the protective sleeves surrounding the radiation source) and the like. Other advantages of the present radiation sensor system include: incorporation of an integrated reference sensor, safe and ready reference sensor testing, UVT measurement capability and/or relatively low cost and ease of manufacture.

Abstract: The invention relates to an ultraviolet radiation lamp. The lamp comprises a substantially sealed cavity comprising a mercury-containing material; a filament disposed in the sealed cavity; and an electrical control element in contact with the filament, the electrical control element configured to adjust or maintain a temperature of the mercury-containing material with respect to a prescribed temperature. Such a constructions allows the present ultraviolet radiation lamp to be operated at optimal efficiency without the need to use additional components to add heat to and/or remove heat from the mercury-containing material.

Abstract: There is disclosed a fluid filter device. The fluid filter device comprises: a primary filter section having a first porous section; and a secondary filter section having second porous section; wherein: (i) the primary filter section and the secondary filter section are in fluid communication with one another, and (ii) the first porous section has a greater porosity than the second porous section. There is also disclosed a fluid isolation device for isolation an exterior fluid from a surface of an enclosure containing interior fluid. The device comprises a sleeve element movable between: (i) a retracted portion in which exterior fluid contacts the surface of the enclosure, and (ii) an extended position in which exterior fluid is isolated from contacting the surface of the enclosure. A distal portion of the sleeve element is configured to actuate a backwash element configured to backwash the interior fluid from the enclosure when the sleeve element is in the extended position.

Abstract: The present invention relates to a fluid treatment system comprising: an inlet; an outlet; and a fluid treatment zone disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) an. elongate first radiation source assembly having a first longitudinal axis, and (ii) an elongate second radiation source assembly having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and to a direction of fluid flow through the fluid treatment zone. The present fluid treatment system has a number of advantages including: it can treat large volumes of fluid (e.g., wastewater, drinking water or the like); it requires a relatively small "footprint"; it results in a relatively lower coefficient of drag resulting in an improved hydraulic pressure loss/gradient over the length of the fluid treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby obviating or mitigating of breakage of the radiation source and/or protective sleeve (if present). Other advantages are discussed in the specification.

Abstract: There is described a fluid treatment system comprising: (i) a fluid inlet; (ii) a fluid outlet; and (iii) a fluid treatment zone in fluid communication with the fluid inlet and the fluid outlet. The fluid treatment zone comprises a housing within which is disposed a fluid separation section (the separation section may include a single separation device or a combination of two or more similar or disimilar separation devices) and a fluid radiation section in fluid communication with one another. The fluid separation section removes solids in the fluid and the fluid radiation section irradiates the fluid to deactive microorganisms in the fluid. The fluid separation section and the fluid radiation section are configured to have a substantially common fluid flow path which significantly reduces the space or footprint requirement of and/or significantly reduces hydraulic head loss (pressure drops) in the overall fluid treatment system while allowing the two sections to perform their respective functions.

Abstract: There is described a fluid treatment system in which fluid to be treated is impinged under pressure on a radiation emitting surface. The fluid treatment system includes at least one radiation source having a radiation emitting surface and at least one nozzle element having a fluid discharge opening spaced from the radiation emitting surface. The fluid discharge opening is configured to impinge fluid to be treated on to at least a portion of the radiation emitting surface. The fluid treatment system is well suited to treating low transmittance fluid.

Abstract: A fluid treatment system for placement in a flanged pipe fluid conveyance system includes: a first flanged opening and a second flanged opening in substantial alignment to define a flow axis aligned substantially parallel to a direction of fluid flow though the first opening and the second opening; and a third flanged opening comprising a first cover element. The first cover element has connected thereto at least one radiation source assembly comprising at least one elongate radiation source having a longitudinal axis substantially transverse to the flow axis. The fluid treatment system may be advantageously utilized to treat fluid such as water, e.g., municipal waste water, municipal drinking water and the like. The fluid treatment system can be readily "spliced" into existing into existing piping systems. This facilitates installation of the system and also allows for a significant lowering of manufacturing costs of the system.
