Filter media that are made of metal fiber fleece have been qualified as a very suitable method to clean engine oils from fine particles in large diesel application. However, regeneration by backflushing of these densely packed depth filtration media is a great challenge. In experimental studies, the principles of successful hydrodynamic backflushing could be identified. Furthermore, the auxiliary effects of medium‐ and high‐power ultrasound on this process were investigated and could be qualified. Ideal process parameters for the general aim of freeing filter media from clogging particle fractions whilst using minimized amounts of flushing medium can be derived. This generates input parameters for an optimized apparatus design in real‐scale application.
