Automatic control represents a promising technology, which can further improve current effluent quality, process robustness and operational cost. Designing a successful controller requires detailed know-how about the entire system: (1) the process to be controlled; (2) the instrumentation and actuators; and (3) the automation and control system. Despite the increasing level of detail in wastewater treatment process models, oversimplified energy consumption models (i.e. constant “average” power consumption) are frequently being used in optimization exercises. This paper deals with the validation of a newly developed dynamic model for a more accurate calculation of pumping energy (applied to centrifugal AC motor driven pumps), function of desired pumped flow rates. This paves the way towards new, improved control strategies for energy optimization of WWTPs.
