A sludge forming a uniform non-compressible cake is filtered through a filter press out of which one frame is kept under study. At a constant pressure difference of 2.8 kg/cm², a 10 cm cake is formed in one hour with a filtrate volume of 6000 liters. Three minutes are needed to drain liquor from filter. Two minutes are needed to fill the filter with water. Washing proceeds exactly as filtration using 1200 liters. Opening dumpling and closing take 6 minutes. Assume the filtrate has the same properties of wash water and neglect the resistance offered by cloth and flow lines. How many liters of filtrate are produced in 24 hours on the average?
