Example 10.1 Evaluation of Filtration Constants for Constant-Pressure Filtration.
Data for the laboratory filtration of CaCO3 slurry in water at 298.2 K (25 °C) are reported as
follows at a constant pressure ( − ΔP ) of 338 kN/m2 (7,060 lbf/ft2) (R1, R2, M1). The filter area
of the plate-and-frame press was A = 0.0439 m2 (0.473 ft2) and the slurry concentration was
S C = 23.47 kg/m3 (1.465 lbm/ft3). Calculate the constants α and m R from the experimental
data given, where t is time in s and V is filtrate volume collected in m3.
