The dynamic simulation method proposed by Lu and Hwang (1993) has been extended to determine the relationships of cake porosity and specific filtration resistance versus solid compressive pressure from constant rate filtration data. The simulated results for different compactness materials agreed very well with the corrected compression-permeability cell (C-P cell) test data and dynamic analysis results of constant pressure filtration. Using the results obtained from these dynamic analyses to predict the performance of filtration of various slurries, the results agreed very well with an average deviation of around 4%, while the corrected C-P cell test data result in an average deviation of approximately 5%.
