Quantification of Energy Savings for Different Pumping Options – A Case Study

Energy modeling and optimization at WWTPs is an area of significant interest and methods to quantify the energy consumption in different unit processes are needed to make better decisions. The paper shows the implementation of pump energy model in GPS-XTM process simulator and its application to quantify energy consumption in a pumping system considering pump and system characteristics curves and flow variability. The model provides a useful tool for system designers to quantify the energy saving potential from different pumping options. The model can also be used for pump selection and pump operation optimization.
