3. A slurry of CaCO3 in H₂O is to be filtered in a press having a total area of 8 m² and operated at a constant pressure drop of 2 atm. The mass fraction of solids in the feed to the press was 0.139. The frames are 36 mm thick, establishing the maximum cake thickness. Assume that the filter medium resistance in the large press is 5 x 10¹⁰ m²¹, and that the permeability of the cake is 1.2 x 10-¹4 m². Use a cake density of 1120 kg/m³ and neglect water retained in the cake. Calculate the filtration time required and the volume of filtrate obtained in one cycle of operation. 3.
