Abstract
A system and method for treating a fluid carrying a biological contaminant to which a photoactive material has been bound include a treatment device that defines a flow passage with a gap. The system and method operate to establish a flow of fluid from the inlet end of the gap to the outlet end of the gap. The system and method expose the fluid, as it transits the gap, to a source of radiation that activates the photoactive material bound to the contaminant. The system and method also mix the fluid as it flows within the gap.
