Patent number: 7691343Abstract: 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: May 9, 2003Date of Patent: April 6, 2010Assignee: Trojan Technologies Inc.Inventor: Peter Ueberall

Patent number: 7683339Abstract: An optical radiation sensor system having: 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 structure 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.Type: GrantFiled: September 20, 2007Date of Patent: March 23, 2010Assignee: Trojan TechnologiesInventors: Jennifer Gerardi-Fraser, Jim Fraser, Joel Helin

Publication number: 20090294689Abstract: 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: December 21, 2006Publication date: December 3, 2009Applicant: Trojan Technologies Inc.Inventors: Jim Fraser, Michael Sasges

Patent number: 7531095Abstract: An ultraviolet fluid treatment system having feedback control using a kinetic model and a reactor model that interact with one another. The kinetic model uses readily measured fluid properties upstream and downstream of a radiation zone to calculate the conversion of a target contaminant as it passes through the fluid treatment system. This obviates the need to measure the contaminant concentration directly, which generally is too slow to permit real-time control. A reactor model relates system operating cost to system operating parameters, such as electrical power consumption and/or rate of oxidant addition, where applicable. The reactor model is linked to the kinetic model and is used to optimize operating cost by adjusting system operating parameters based on a comparison between the conversion obtained from the kinetic model and the overall treatment objectives. A control center, an ultraviolet fluid treatment apparatus, and a method of treating a fluid are also disclosed.Type: GrantFiled: March 10, 2005Date of Patent: May 12, 2009Assignee: Trojan Technologies Inc.Inventors: Christian Williamson, Alan Royce, Mihaela I.

Patent number: 7442312Abstract: A process for treating a fluid which comprises the step of exposing the fluid to ultraviolet radiation and high-energy ionizing radiation. It has been discovered that combining ultraviolet radiation with high-energy ionizing radiation in the treatment of a fluid results in synergistic performances of the treatment process—e.g., improvement in the inactivation or killing of microorganisms in the fluid, in destruction of organic contaminants and the like. More specifically, fluid treatment performance is improved to a level typically not possible when using ultraviolet radiation and high-energy ionizing radiation separately.Type: GrantFiled: August 19, 2002Date of Patent: October 28, 2008Assignee: Trojan Technologies Inc.Inventor: Fariborz Taghipour
