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: There is described an on-line device for controlling a fluid treatment process configured to inactivate a microorganism in a flow of fluid using ultraviolet radiation and a chemical disinfectant. The device includes: a memory for receiving a calculated database of dose response for the ultraviolet radiation and for the chemical disinfectant for a fluid treatment parameter; means to obtain input data about the fluid treatment parameter from the process; means to compare the input data with calculated database; and means to adjust one or more of the amount ultraviolet radiation and the chemical disinfectant added to the flow fluid in response to a difference between the input data and calculated database. There is also described a process for controlling a fluid treatment process configured to inactivate a microorganism in a flow of fluid using ultraviolet radiation and a chemical disinfectant.

Abstract: In one of its aspects, the invention relates to a process to optimize the dose of a treatment agent for the treatment of a fluid comprising a contaminant. In this first aspect the process comprises the steps of: (a) calculating the dose of the treatment agent based on the relationship between concentration of the treatment agent at one or more points and residence time distribution of the treatment system, and (b) contacting the fluid with the treatment agent in the concentration required to meet the dose calculated in step (a). In another one of its aspects, the invention relates to a process to optimize the dose of a treatment agent for reduction of a contaminant in a fluid.
