    Abstract: There is disclosed an optical radiation sensor system for detecting radia tion from a radiation source. The system comprises: a housing having a dista l portion for receiving radiation from the radiation source and a proximal p ortion; a sensor element in communication with the proximal portion, the sen sor element configured to detect and respond to incident radiation received from the radiation source; and motive means configured to move the housing w ith respect to the sensor element between at least a first position and a se cond position. A radiation pathway is defined between the radiation source a nd the sensor element when the housing is in at least one of the first posit ion and the second position. Movement of the housing with respect to the sen sor element causes a modification of intensity of radiation impinging on the sensor element. In its highly preferred embodiment, the radiation sensor sy stem 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 hav e built-in diagnostics for parameters such as sensor operation, radiation so urce output, fluid (e.g., water) UVT, radiation source fouling (e.g., foulin g of the protective sleeves surrounding the radiation source) and the like. Other advantages of the present radiation sensor system include: incorporati on of an integrated reference sensor, safe and ready reference sensor testin g, UVT measurement capability and/or relatively low cost and ease of manufac ture.

    Abstract: The present invention relates to a fluid treatment system, more particularly an ultraviolet radiation water treatment system, comprising: an inlet (112); an outlet (124); and a fluid treatment zone (120) disposed between the inlet and the outlet. The fluid treatment zone has disposed therein: (i) a first bank (126) of elongate radiation source assemblies having a first longitudinal axis, and (ii) a second bank (128) of elongate radiation source assemblies having a second longitudinal axis. The first longitudinal axis and the second longitudinal axis are non-parallel to each other and oblique 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).

    Abstract: A fluid treatment system (100) for placement in a flanged pipe fluid conveyance system. The fluid treatment system (100) comprises a flanged ductile iron pipe fitting (105). The ductile iron pipe fitting (105) comprises: a first flanged opening (110) and a second flanged opening (120) in substantial alignment to define a flow axis aligned substantially parallel t o a direction of fluid flow (A) through the first opening (110) and the second opening (120); and a third flanged opening (130) comprising a first cover element (155). The first cover element (155) has connected thereto at least one radiation source (150) assembly comprising at least one elongate radiati on source having a longitudinal axis substantially transverse to the flow axis. In its preferred form, the fluid treatment system may be advantageously utilized to treat fluid such as water, e.g., municipal waste water, municipa l drinking water and the like. The fluid treatment system is particularly advantageous since it utilizes a standard ductile iron pipe fitting (105) an d thus, can be readily "spliced" into existing piping systems. This facilitate s installation of the system and also allows for a significant lowering of manufacturing costs of the system.

    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 flow modifier device comprising: an inlet portion for receiving a flow of fluid; an outlet portion for outputting the flow of fluid; and a flow modifier portion disposed between the inlet portion and the outlet portion, the flow modifier portion comprising an outer portion comprising a closed cross-section to the flow of fluid and an inner porous portion configured such that at least a portion of the flow flow received in the inlet portion must pass through the inner porous portion to reach the fluid outlet. The fluid flow modifier device is ideally used to transition fluid flow between an fluid supply line and a fluid treatment zone - for example, a pressure water supply line and an ultraviolet radiation treatment device (e.g., drinking water treatment device).
