Wastewater treatment plants are complex operating facilities that are currently planned and dimensioned using steady-state design approaches. In the case of special process requirements, the tool of dynamic simulation is applied to model all process-related functions of the machinery and the detailed automation system. For the planning and building phase, but also for subsequent operation, a large number of specialist disciplines must therefore be efficiently and effectively interlinked. Only in this way is it possible to ensure a safe, sustainable and energy-optimised operation. With Building Information Modelling (BIM), this interdisciplinary cooperation can be standardised and realised, however, a coupling to the dynamic wastewater treatment plant simulation is currently not possible due to the lack of a software foundation.
The objective of the DynaBIM project is to integrate wastewater treatment plant simulation into the BIM methodology in order to achieve dynamisation for the first time. This will enable any potential user (e.g. software developers, engineering companies, research) to access data and information of each phase of the life cycle of a wastewater treatment plant transparently. Specifically, DynaBIM aims at the prototypical development of a virtual 3D wastewater treatment plant that imports detailed structural information from a subject-specific openBIM model and links it with dynamic material flow information from a wastewater treatment plant simulator, and this within the framework of a Virtual (VR), Mixed (MR) and Augmented Reality (AR) environment. The virtual 3D wastewater treatment plant can be used for training and educational purposes as well as in daily wastewater treatment plant operations.
Figure: Graphical summary of the envisaged objectives in DynaBIM. While building geometries and object data of wastewater treatment plants can be modelled within openBIM to a limited extent, wastewater qualities can be used to create digital twins of wastewater treatment plant simulators without restrictions. A direct data link between openBIM and digital twin does not exist and will be developed within the framework of DynaBIM in order to develop a virtual 3D wastewater treatment plant as an example application form of this newly developed software foundation (dashed line).
