FhG CBP – Mechanical separations

At Fraunhofer CBP a screw press with a capacity of 800 L per hour is used for pulp separation. Filter, drum filter, chamber filter and membrane filter presses are available partly with ATEX admission. For example, the membrane filter press is used for separation of precipitated lignin from ethanol containing black liquor. It can hold a volume of up to 90 L and can filter particles down to the diameter size of 0.5 μm. Continuous cross flow membrane filtration systems are available for ultra- and microfiltration partly with ATEX admission. The skid filter area is up to 20/17 m² (MF/UF) and the cut-off is 0.2 µm for MF and 10 kDa for UF.
