Patent number: 9533060Abstract: 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.Type: GrantFiled: June 30, 2010Date of Patent: January 3, 2017Assignee: Trojan Technologies Inc.Inventors: Douglas Penhale, Joseph Elku

Patent number: 9115009Abstract: 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.Type: GrantFiled: May 11, 2010Date of Patent: August 25, 2015Assignee: Trojan Technologies Inc.Inventor: Jim Fraser

Patent number: 8859989Abstract: A fluid treatment system having an inlet, an outlet, and a fluid treatment zone therebetween. The zone has an array of rows of radiation source assemblies. Each radiation source assembly has a longitudinal axis disposed at an oblique angle with respect to a direction of fluid flow. Each row has a plurality of radiation source assemblies in spaced relation in a direction transverse to the direction of fluid flow, to define a gap through which fluid may flow between an adjacent pair of assemblies. Preferably, all rows in the array are staggered with respect to one another in a direction orthogonal to the direction of fluid flow, such that the gap between an adjacent pair of radiation source assemblies in an upstream row of assemblies is partially or completely obstructed in the direction of fluid flow by a serially disposed radiation source assembly in at least one downstream row.Type: GrantFiled: June 18, 2013Date of Patent: October 14, 2014Assignee: Trojan Technologies Inc.Inventors: Wes From, Boyko M. Tchavdarov, Mike Marcu, Richard Gratton, David Olson, Jim Fraser, Dusko A. Kezele

Patent number: 8507874Abstract: A fluid treatment system having: an inlet; an outlet; and a fluid treatment zone disposed therebetween. The fluid treatment zone has: (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 and second longitudinal axes are non-parallel to each other and to a direction of fluid flow through the treatment zone. The present fluid treatment system 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 treatment system; and it results in relatively lower (or no) forced oscillation of the radiation sources thereby mitigating breakage of the radiation source and/or protective sleeve (if present).Type: GrantFiled: April 2, 2012Date of Patent: August 13, 2013Assignee: Trojan Technologies Inc.Inventors: Wes From, Boyko M. Tchavdarov, Mike Marcu, Richard Gratton, David Olson, Jim Fraser, Dusko A. Kezele

Patent number: 8246839Abstract: The object of the invention is a double-walled chamber for the UV disinfection of liquids, preferably drinking water and/or waste water. It realizes a rectangular and/or square cross-sectional shape of the UV radiation chamber even at higher pressures, whereby the radiation chamber can moreover be provided with a thin-walled configuration and allows an optimal and close arrangement of UV radiators as compared with a round chamber. By applying the inventive idea, the known dead zones at the entrance are completely eliminated and an entrance turbulence is produced which runs simultaneously with the piston flow in the chamber.Type: GrantFiled: April 1, 2010Date of Patent: August 21, 2012Assignee: Trojan Technologies Inc.Inventor: Peter Ueberall

Publication number: 20110240880Abstract: There is described a fluid treatment system which may which may be used with radiation sources that do not require a protective sleeve—e.g., excimer radiation sources. An advantage of the present fluid system treatment is that the radiation sources may be removed from the fluid treatment zone without necessarily having to shut down the fluid treatment system, remove the fluid, break the seals which retain fluid tightness, replace/service radiation source and than reverse the steps. Instead, the present fluid treatment system allows for service/replacement of the radiation sources in the fluid treatment zone during operation of the fluid treatment system.Type: ApplicationFiled: June 15, 2011Publication date: October 6, 2011Applicant: TROJAN TECHNOLOGIES INC.Inventors: JIM FRASER, Michael Sasges
