Abstract
Methods and apparatus for precisely controlling a light treatment of a treatment system for treating a product. In one implementation, a method for use with a fluid treatment system using light comprises the steps of: estimating a particular velocity of moving particles within a fluid flowing through a treatment chamber of the fluid treatment system using pulses of light as a light treatment, the fluid flowing at a mass flow velocity, the treatment chamber and the fluid being transmissive to at least 1% of light having at least one wavelength within a range of 170 to 2600 nm; and setting a flash rate of the pulses of light based on the particular velocity in order to optimize the light treatment. Furthermore, in preferred implementations, the light treatment is for the deactivation of microorganisms, including viruses, bacteria, fungus and other pathogenic and non-pathogenic microorganisms.
