Optimising municipal wastewater processes

Achieving significant energy savings with a model-aided design approach

ETC Sustainable Solutions needed to optimise treatment processes in existing municipal wastewater treatment plants (WWTPs). In order to find the optimal solution for revamping the WWTPs, they initiated two studies to examine the potential benefits of a model-based design approach for the installation of their OSCAR® controller. For these studies, they used our MIKE Powered by DHI WEST modelling software under dynamic conditions. By using a model-based design approach, they were able to successfully develop and evaluate control strategies and achieve energy savings in bioprocesses of up to 60%.
