It is desired to filter a cell broth at a rate or 2,000 L/h on a rotary vacuum at a vacuum pressure of 70 kPa. The cycle time for the drum is 60 s and the cake formation time is 15 seconds. The broth to be filtered has a viscosity of 2.0 cp and a cake solids (dry basis) per volume of filtrate of 10 g/L. From laboratory tests, the specific cake resistance has been determined to be 9x1010 cm/g. Determine the area of the filter that is required. The resistance of the filter medium can be neglected.
