Cross Flow Filtration

Dynamic Cross-Flow Filtration – Simulations in Process Engineering

One problem in filtration is the blocking of the filter by particles that deposit on the membrane (membrane fouling). This leads to a decrease in performance of the filter. To prevent the formation of a fouling layer, a flow tangential to the membrane is induced in cross-flow filtration. This can be achieved by a rotor. In a project at KIT this dynamic cross-flow device has been tested for the purification of proteins, since a high disperse phase fraction can be achieved.
