PROBLEM SOLVING #28, Given: a standard leaf filter is being used in filtration. of a sludge. The wash water volume used is 15% of the filtrate volume. The mass of dry cake collected per volume of filtrate collected is 25 kg/m³ The total pressure drop across the filter cake and 15 m² of leaf filter is. 350 kilopascals. The resistances for the cake and the filter medium are 1.85 x 10" m/kg and 10.5 x 1012 per meter viscosity of liquid = 8.937 x 10 The cleaning 4. Pa-s and assembly time takes 30 minutes. Solve for the total filtration time of 1 cycle or batch collecting 5 m³ of filtrate.
