Patent ID: 7531095

Claim:
An ultraviolet fluid treatment system for treating a fluid containing a contaminant, the system comprising: a fluid inlet, a fluid outlet, and an ultraviolet radiation zone between the fluid inlet and the fluid outlet; an upstream measurement point configured to measure a first set of fluid properties upstream of the radiation zone; a downstream measurement point configured to measure a second set of fluid properties downstream of the radiation zone; a controller configured to cause one or more fluid treatment system parameters to be adjusted; and a programmable logic device programmed with a kinetic calculation model that outputs a conversion value of the contaminant based on the first and second sets of fluid properties, said programmable logic device also programmed with a reactor calculation model that calculates an adjustment to the one or more of the fluid treatment system parameters based on the output conversion value, the programmable logic device outputting the calculated adjustment parameters to the controller, which in response thereto adjusts the one or more fluid treatment system parameters.
