Abstract: A mathematical model for constant pressure filtration is established. The distribution of
hydraulic pressure within the cake and the medium resistance are measured. The medium
resistance Rm is calculated from the suppositional filtration time θm. It is demonstrated
that Rm is nearly a constant for a given filter cloth.

Key words: filtration, medium resistance, mathematical model
