  • Varying water level solids and tracking control
    Patent number: 11858837
    Abstract: A sequencing batch reactor includes a liquid level sensor configured to measure a level of liquid in the vessel and provide an indication of the level of the liquid to a controller and a sludge detector configured to measure a position of an interface between sludge and solids-lean supernatant in the vessel and to provide an indication of the position of the interface to the controller. The controller is configured to perform a comparison between the level of the liquid and the position of the interface and control an amount of solids-lean supernatant removed from the vessel during the decant stage based on the comparison.
    Type: Grant
    Filed: November 16, 2020
    Date of Patent: January 2, 2024
    Assignee: Evoqua Water Technologies LLC
