A graphical user interface as a DSS tool for GHG emission estimation from water resource recovery facilities

For most of engineering applications, mathematical models can represent valuable support tools as they provide useful information for the decisional process without the time, cost and risk of an experimental activity. For instance, in the environmental applications, mathematical models can be used to estimate the GHGs emissions from the different sections of a wastewater treatment plant (WWTP). However, in most of the cases mathematical models come in complex form and thus are not accessible to practical users. In this work, four models aimed at quantifying the gas emissions from the aerated tanks, aerobic digesters, secondary clarifiers and anaerobic digesters are englobed in a GUI in order to provide a valid decision support system (DSS) to the practitioners.
