A slurry of CaCO3 in water at 258C containing 20% solids by weight is to be filtered in a plate-and-frame filter. The slurry and filter medium are tested in a constant pressure lab filter that has an area of 0.0439 m2 , at a pressure drop of 338 kPa. It is found that 103 m3 of filtrate is collected after 9.5 s, and 5  103 m3 is collected after 107.3 s. The plate and frame filter has 20 frames, with 0.873 m2 of filter medium per frame, and operates at a constant flow rate of 0.00462 m3 of slurry per second. The filter is operated until the pressure drop reaches 500 kPa, at which time it is shut down for cleaning. The downtime is 15 min per cycle. Determine how much filtrate passes through the filter in each 24 hr period of operation (SG of CaCO3 is 1.6).
