The basin level control system in an existing wastewater treatment plant is designed for two different operation modes: compliant level control for smooth pump flow, and stiff level control. Both a model-based predictive controller (MPC) and a standard PI controller are implemented, and tested both on a dynamic simulator and on the real plant. The simulator, the MPC and the PI controller tuning are based on a mathematical process model derived from a material balance of the wastewater in the inlet basin.
