Variations of porosity and specific local filtration resistance in cake filtration were studied in a filter cell. Samples used were slurries of CaCO₃, Talc(I) and Talc(II) and diatomite filter aids, which were used by body feeding and precoating. From the experimental result, the porosity of filter cake decreased and the specific local filtration resistance increased with increasing pressure. The addition of filteraids increased the porosity of filter cake and it resulted in decreasing the specific local filtration resistance.
