Abstract

PURPOSE: To reduce a liquid content ratio in a cake after filtering to a large extent by adding a high gas pressure onto a slurry containing fine solids supplied on a filter material.
CONSTITUTION: In gravity filtering of a slurry containing fine solids with a min. particle size of 0.1mm or above, after a cake is formed from the slurry supplied onto an upper surface of a filtering material or during a time when the cake is formed, a gas pressure 1W3 times of a liquid column pressure corresponding to a liquid top height of a capillary pipe is applied into a filtered cake layer of the fine solids and acted on the slurry therein. Thereby, a liquid filled in a gap of particles in a saturated zone is pressed downwardly to reduce a liquid content ratio of the saturated zone to that of a low liquid zone.
