  • Patent number: 9856153
    Abstract: 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.

  • Patent number: 9658102
    Abstract: There is described a method of determining the UV fluence received by a fluid. The method comprises the steps of: (a) irradiating the fluid at an unknown UV fluence; (b) measuring the fluorescence of a test sample of the fluid after irradiation in Step (a) to produce a test signal proportional to the concentration of a prescribed fluorescent composition of matter comprised in the test sample; and (c) determining the value of the unknown UV fluence by comparing the test signal to a calibration curve of a control signal proportional to concentration of the prescribed fluorescent composition of matter in the fluid as a function of applied UV fluence. There is also described a system for determining the UV fluence received by a fluid being treated in UV fluid treatment system comprising at least one UV source.

  • Patent number: 9115009
    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 dissimilar 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.
