The energy consumption of wastewater treatment plants for the purification of wastewater depends on the aggregates used. In order to make wastewater treatment as efficient and space-saving as possible, the use of a low-maintenance filter system (textile curved sieve) was tested in the project. A textile with a pile structure developed by the Institut für Bodensysteme at RWTH Aachen e.V. (TFI) was used as the filter medium. This was installed in place of the rigid screen surface of a curved sieve and was used to separate liquids from solids. In addition to the filtration of the developed textile curved sieve, the cleaning of the textile was also investigated.

The final report can be obtained from the research institutions.
