A slurry containing 15 wt% solids (SG = 2.7) in water at 20oC is to be filtered in a plate-and- frame filter press. The filter press has 30 frames, with 1.0 m2 area of filtration per frame, and operates at a constant filtration rate of 210 L of filtrate per minute. The filter is operated until the pressure drop reaches 300 kPa, at which time it is shut down for washing and cleaning. Filter cake washing will be undertaken at the same rate as the filtration rate using a volume of wash water equal to one-half of the total filtrate volume collected. Dismantling, cleaning and refitting of the filter takes 17 min. The filter cake produced is compressible with the specific cake resistance () varying with the compressive pressure (Ps) as follows:  0.2789 1 s3.67 10 P , mkg    Pa Page 2 of 3 The filter medium resistance (Rm) is essentially constant with 10 1 mR 6.87 10 m   . If the average voidage of the filter cake produced is 0.4, determine: a. The volume of filtrate collected and thickness of filter cake produced per cycle. b. The filtration cycle time
