Wastewater treatment system and method of control

摘要

A wastewater treatment system for treating a wastewater stream from industrial and municipal sources uses a control system to sequence and supervise the treatment steps in a batch flow mode of operation or a continuous flow mode of operation. In operation, the wastewater treatment system predominantly operates in the batch flow mode. However, the wastewater treatment system operates in a continuous flow mode when the influent wastewater stream exceeds the system's nominal design flow transition point. The control system receives an input signal, relating to the influent flow rate, and switches one or more reactors of the wastewater treatment system from the batch flow mode to a continuous flow mode according to a control algorithm.
