Patent number: 7077965Abstract: There is described a fluid treatment system comprising an array of independent fluid treatment reactors. The reactors are arranged in a manner whereby a flow of fluid may be passed through the array in a substantially helical direction. The fluid treatment system is capable of treating large volumes of fluid (e.g., water) while requiring a relatively small foot print. In essence, the present fluid treatment system concentrates a relatively large number of radiation sources in a relatively small amount of space resulting in the ability to treat large volumes of fluid (e.g., water).Type: GrantFiled: September 20, 2002Date of Patent: July 18, 2006Assignee: Trojan Technologies Inc.Inventors: Christian Williamson, Douglas Penhale, Scott Roger

Patent number: 6803586Abstract: It is often desirable to operate ultraviolet (UV) water treatment systems at high fluid velocities; such as, when low UV doses are required, the UV transmittance of the water being treated is high, or when a high intensity radiation source is used. The operation of an open channel UV fluid treatment system at high fluid velocity causes a disproportionate amount of water to pass through the relatively low intensity region above the top lamp. This results in non-uniform UV dose delivery and poor reactor performance. In one embodiment of the invention, by elevating the inlet to the irradiation zone of the fluid treatment system with respect to the outlet, the amount of water that passes above the top lamp can be minimized, improving overall system performance. The means of elevation can consist of a step or slope in the channel, or a combination of both. Depending on the magnitude of elevation, an increase in maximum velocity of approximately two times can be obtained.Type: GrantFiled: May 8, 2000Date of Patent: October 12, 2004Assignee: Trojan Technologies Inc.Inventors: Robert A.
