The aim of this experiment is to determine and to optimize the complex process inside a large-scale industrial water treatment plant developed by the German SME akvola. Those plants deploy a flotation-filtration-process, in which akvola’s MicroBubble Generator induces fine gas bubbles using very little energy and very little space. This approach allows Akvola to achieve outstandingly high separation efficiency in even harsh environment conditions. With the current development approach, akvola’s new plants are designed based on experience and extrapolation and are then validated through prototyping and experimental testing. This is, however, extremely difficult and costly, because of the large dimensions of the plants and the high costs of the individual components. The approach to plant design in this project is using a completely CAE based workflow instead, which will be developed by NAVASTO.
There, limiting the computational effort required for the simulation of the water treatment process is essential for maximizing the business benefit for the end-user akvola. To achieve this benefit, the computational domain needs to be decomposed along the lines of phase compositions and variable porosities, treated isolated and then coupled back together through the workflow in the form of inlet and outlet conditions to the adjacent domains. The project is conducted primarily to the end of investigating the viability of using a purely CAE based design and optimization process to eliminate the need for prototyping and experimental testing, which is expected to reduce the design costs by several 100k€ per individual plant development. The secondary objective for the project is for NAVASTO – supported by Arctur – to integrate a NAVASTO developed optimization toolbox into the Fortissimo 2 marketplace and to commercialize the software through it.
