The drum is supported for rotation so that a portion thereof is immersed into the substance to be filtered. The pressure within the drum is reduced by a vacuum pump so that the liquid component of the substance is drawn into the drum through the portion thereof is immersed into the substance while the solid component of the substance is accumulated on the filter cloth of the rotating drum and is held as a cake thereon.
