A Software Emulator for the Modelling and Control of an Activated Sludge Process in a Wastewater Treatment Plant

The design and implementation of a simulator, as a real-time application, for a complex process from the biological treatment stage of a wastewater treatment plant (WWTP), is addressed. More precisely, this emulator was achieved as a software tool that can be later integrated into a more complex SCA...
