The SpheroFilt project aims to develop a patented process for the mechanical filtration of particulate solids from water. The concept is characterized by a fully automated and highly concentrated removal of the filter cake from the separation zone and at the same time an uninterrupted filter operation. On the one hand, the previously unachievable combination of depth filtration and cross-flow principle, on the other hand, an application as a granular surface filter with significantly increased permeate yield is possible. The application, which is based on the use of circulating glass beads, combines the advantages of both flow regimes and filtration principles while avoiding their disadvantages.
