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).

IPC Classes  ?

• B01D 33/70 - Filters with filtering elements which move during the filtering operation having feed or discharge devices
• B01D 33/048 - Filters with filtering elements which move during the filtering operation with filtering bands or the like supported on cylinders which are pervious for filtering with endless filtering bands
• B01D 33/44 - Regenerating the filter material in the filter
• B01D 33/62 - Handling the filter cake in the filter for purposes other than for regenerating for drying
• G05D 11/02 - Controlling ratio of two or more flows of fluid or fluent material
