4. Aquatic slurry containing 200 kg solid particles per m of slurry passes through a plate-and-frame filter with 21 plates with dimensions 30 cm x 30 cm. The distance between the plates is 10 cm. Filtration takes place under constant pressure drop equal to 8 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 20% 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/m?, and specific resistance 5 x 109 m/kg. The resistance of the filter medium is 5 x 1010 m 2 (1 bar = 105 kg/(ms)) [Use two digits for the quantities you estimate] Plate and Frame Press Moles forming we continuous channels Ende Central and the Frame Filter cloth or pad Plate Wasis Water Support bar Feed Filtre F3.5 Fler pow.
