Abstract: There is described a system and a process for optimizing and controlling upstream fluid treatment processes using information on fluid characteristics obtained from response variables of a separation device (such as the belt speed or water level of an RBF). This system and process allow for the upstream or downstream treatment processes to be adjusted and optimized against the instantaneous operating conditions of the separation device such that both the pre-treatment and post-treatment processes and the separation system always run at an optimal efficiency. Additionally, since the information obtained from the response variables of the separation device truly reflect the fluid characteristics at the point where the separation system is installed, the same can be used to control a downstream process (for example, the amount of oxygen required in the biological oxidation stage or the sludge retention time in an side stream sludge treatment process such as fermentation or anaerobic digestion).

Abstract: The is described a process for determining a validated Reduction Equivalent Dose for reducing the concentration of a target contaminant contained in a fluid in a radiation fluid treatment system. In one embodiment, the process comprises the steps of: (a) determining a short wavelength Reduction Equivalent Dose for the target contaminant or a challenge contaminant in a first region of the electromagnetic spectrum having a wavelength of less than or equal to about 240 nm; (b) determining a long wavelength Reduction Equivalent Dose for the target contaminant or a challenge contaminant in a second region of the electromagnetic spectrum having a wavelength of greater than about 240 nm; and (c) summing the short wavelength Reduction Equivalent Dose and the long wavelength Reduction Equivalent Dose to produce the validated Reduction Equivalent Dose for the target contaminant.
