Wastewater treatment plants are used globally to reduce the effects of anthropogenic pollution on aquatic ecosystems. These stations operate on similar principles, but with design differences depending on the needs for which they were built. In order to avoid certain environmental risks and to increase the performance of these stations, automatic control strategies are implemented. Therefore, each wastewater treatment plant presents control strategies that vary from case to case. This paper presents results obtained from the implementation of a dissolved oxygen control strategy, at the level of the bioreactor of a simulated wastewater treatment plant, in order to streamline the nitrification and denitrification processes. The simulations were performed on the BSM2 model (Benchmark Simulation Model No.2).
