A rotary vacuum filter for the separation of solids-liquid mixtures has a rotatably supported filter drum having a stationary hollow conduit extending through the interior of the drum which is attached to a vacuum pump. The drum is rotated in a tank containing a mixture to be separated, so that the vacuum action draws the mixture through a filter disposed on the surface of the drum into the interior thereof, where an interior pump removes the filtered liquid and discharges same through the hollow conduit. At no time during the filtration process is air mixed with the filtered liquid, so that subsequent processing to remove air from the liquid is not required. |
