Optimal control strategies for SBR's

The objective of the control system developed in Narbonne was to design an algorithm able to drive any initial condition to a final target in a minimal time. More specifically, it is related with the development of a time optimal control strategy for the control of a batch reactor working in two modes: aerobic and anoxic. The challenge was to find the switching instants of a predefined control sequence {aerobic-anoxic-aerobic} and maintain a high nitrification and carbon removal activities.

The control strategies provided tools to minimize the reaction time and ensure high purification performances. In a second step, it allowed to increase the wastewater volume treated within a time interval. The increase of the loading rate was taken into account as constraint in order to maintain good biological activities for nutriment removal and a good settling capacity for the sludge. This last point is important in order to guarantee an optimal separation of the purified water and the biomass.
