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: A fluid treatment system for treating a fluid with ultraviolet light. The system includes a detachable light source assembly having a thermally conductive outer wall, an inner wall disposed inside the outer wall and surrounding an inner space within the inner wall that defines a treatment zone, and an ultraviolet light source disposed between the outer wall and the inner wall and configured to emit ultraviolet light toward the treatment zone, and a reactor vessel having an inlet port for receiving a fluid and an outlet port for expelling treated fluid, the reactor vessel configured to receive the light source assembly in an attached state such that a space between a wall of the reactor vessel and the outer wall of the light source assembly defines a cooling zone in which the outer wall is cooled by contacting the fluid.
