Development of an ultrasound-based Fouling-Monitoring-Solution for in-situ detection and prediction of scalings and biofilms in geothermal power plants and open cooling circuits

The output of geothermal power plants is significantly compromised by fouling occurring in process water piping and heat exchangers. The aim of this project is to develop a monitoring solution, which allows counteractive measures to be implemented via an early warning system. To this end, an innovative, temperature-stable ultrasound sensor network will be devised in order to characterize fouling. In cooperation with the project partners, a software will be created which is able to predict when a critical degree of fouling will be reached, based on the ultrasound data. Thus, preventive and cleaning measures can be taken in a targeted manner at an early stage.
