ABSTRACT:
Apparatus for the separation of suspended solids from a fluid under pressure, by means of a granulate-bed, consisting of granulates of at least two sizes of grain of a material which does not swell during the filtration operation. During the filtration operation, the fluid flows through the granular medium filterbed in one direction and filtrate used for backwashing the separated solids flows in the opposite direction. The granulate-bed is held firmly together during the filtration operation and during the purification by a compression source, that generates such a compression on the granulate-bed, that it keeps the relative position of the granulate-particles with respect to each other in the granulate-bed, both under the action of flow during filtration process as well as during the purification process, in essence permanently in place.
