Abstract: Methods of operating a system for treating a fluid flowing through a reactor with ultraviolet (UV) light emitted from a light source assembly. One method includes detecting, with a flow sensor, a flow rate of fluid through the reactor; and controlling, with a processor, electric power supplied to the light source assembly so that a low average amount of electric power is supplied when the flow rate is below a threshold. In another method, an intensity of the UV light may be controlled by the processor based on a detected temperature in the light source assembly. Yet another method includes determining that the flow sensor is defective based on the detected temperature in the light source assembly and the detected flow rate. A further method includes determining that an intensity sensor is defective based on a detected intensity and the detected temperature in the light source assembly.

Abstract: There is described a novel fluid treatment device that can induce Dean Vortices in the flowing fluid, and then induce a new set of Dean Vortices at an angle to those in the first set. Each subsequent curved section can induce vortices at an angle to those in the last curved section. This reactor has the effect of repeatedly twisting and splitting the fluid flow, resulting in targeted mixing similar to that of static mixers without the necessity of utilizing physical mixers. This is also an improvement over helical tubing configurations that generate only a single set of vortices and do not split and mix the flow.
