Detailed dynamic pumping energy models for optimization and control of wastewater applications

by IWA Publishing  (Sep. 30, 2014)

Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant ‘average’ power consumption) are being used in optimization exercises. A new dynamic model for a more accurate prediction of pumping costs in wastewater treatment has been developed to overcome this ...
