Abstract
A control system for an upflow clarification tank comprises a regulator for controlling one or more characteristics of the flow within the tank (such as the power, pressure, velocity, momentum, or velocity head of the flow), a sensor for measuring one or more of the characteristics of the flow, and a linkage that automatically adjusts the regulator to a desired setting based on the sensor measurement. A processor may be used to determine the desired setting for the regulator. The control system may also include structure enabling the operator to manually select between multiple methods for determining the desired setting.
