New Design MSDF is a development moving away from conventional cross flow filtration towards spin filtration. The advantages of spin disk  filtration lies  in the improved cleaning  effect on the filter surface at a reduced energy cost.

Process Operation
Prerequisite for a continuous filtration method is how to avoid filter media blocking by  preventing the formation of a secondary resistive  layer on the filter media surface (filter cake). This always requires continuous cleaning of the filter surface during the process. Conventionally this is being done with tangential or cross flow technologies with high velocity flows. The shear forces that occurred this way prevented the formation of a filter cake.

In order to achieve this cross flow effect, it used to be necessary to move high liquid volumes with powerful pumps. The excellent filtration capacities were offset by high energy costs.

Dynamic cross flow methods work with much less energy consumption. The relative motion between the medium to be filtered and the filter is not generated by pumps but instead by the rotation of the filter elements  or a rotation of flow disrupters.

MSDF membrane systems  operate using  membrane disks of different  MOC  that are configured  in modular stack mode on a rotating shaft.  That separation technology purely relies on the differences in physical sizes in the MF range and in the molecular weight (size) of the individual components when processing in the MF and UF range.  The membrane pore is a safe barrier for any insoluble matter (i.e. protein complexes if any,  triglycerides, fats, oils, bacteria, colloidal matter, fibres etc) irrespective of the incoming concentrations. The selection of the right membrane or filter media is more from experience of working in similar applications.
