4. Aquatic slurry containing 40.3 kg solid particles per m² of slurry passes through a plate-and-frame filter with 21 plates with dimensions 60 cm x 60 cm. The distance between the plates is 10 cm. Filtration takes place under constant pressure drop equal to 5 bar and it is stopped when 1/2 of the volume of the frames are filled with cake. Then, the cake is washed with water volume equal to 5% of the filtrate volume. Find: a. the total volume of filtrate per filtration cycle, b. the filtration time. Given: density of slurry = 1200 kg/m?, viscosity of slurry and water = 1 CP (1 CP = 103 kg/(ms)). The cake is incompressible, contains 20% moisture, it has density 1400 kg/m3, and specific resistance 5 x 10°m/kg. The resistance of the filter medium is 3 x 108m? (1 bar = 105 kg/(ms?))
