Abstract
The filtration data obtained from pressure filtration experiments with a gradual pressure increase have been interpreted by a data evaluatio n program, which takes into consideration the pressure drop in the fil ter medium and the sedimentation of the slurry. The structures of the filter cakes were surveyed by additional particle size measurements. T he results showed that the specific filtration resistance and its pres sure dependence can be obtained in a single filtration test with a gra dual increase in pressure, compared with several tests at different co nstant pressures.
