This work aims to develop and test data-driven nitrous oxide (N2O) control strategies for a full-scale wastewater treatment plant carrying out the activated sludge process in alternating aerobic/anoxic mode. To this end, full-scale real-time data were systematically collected and analysed to infer the underlying mechanisms responsible for N2O emissions during both aerobic and anoxic phases. Based on these findings, potential control strategies were proposed and then tested at full scale to explore their feasibility of mitigating N2O emissions.
