Abstract

A typical wastewater pumping plant comprises a screening process and a pumping process. The first process separates coarse material out of wastewater, while the second one boosts the wastewater toward a treatment facility. Appropriate component models for such plants are hardly found in literature. Indeed, there exist standard component models in all-purpose fluid simulation tool libraries; their generality, however, makes those models too complex to be used for wastewater pumping plants. The lack of models forces engineers to test their control scenarios on real implemented systems, which may lead to unexpected delays and painful costs. In this work, easily manageable component-oriented models are derived and applied to the modeling and simulation of a real wastewater pumping system. The model derived here is implemented in the component-oriented Modelica language, and it helps better understand the system dynamics. Thereby, a tool is provided for evaluating the performance of possible control schemes.
