OPTIMUM AEROBIC VOLUME CONTROL BASED ON CONTINUOUS IN-LINE OXYGEN UPTAKE MONITORING

The optimum aerobic volume control concept (OAV-control concept) is a control strategy based on continuous in-line oxygen uptake monitoring. This concept provides a dynamic adaptation of the aerobic volume required for complete nitrification and therefore maximises the denitrification performance and minimises energy consumption. The OAV-control concept is installed at the WWTP Linz-Asten (1 Mio PE) and shows very good results.
