• Batchwise centrifugal filtration and constant-pressure filtration are compared from the viewpoint of cake structure. To correlate the filtration resistance with a pressure as a unique function, it is essential to account for the sedimentation behavior and to use the average compressive pressure. By using the average compressive pressure as a parameter, convenient and approximate calculating methods are proposed to predict a centrifugal filtration process from the data of constant-pressure filtration. If the procedures of compression permeability tests and theoretical calculations are considered to be tedious, the predicted results can stand comparison with the experimental or precisely calculated results from the compression permeability data. An example of predicted centrifugal filtration process is shown for a practical centrifuge.
