ABSTRACT:
A sector for a disc-shaped filter. The device includes a substantially sector-shaped element having a pair of opposed sides, a pair of opposing edges converging toward each other and terminating in a neck at one end and diverging toward the other direction to terminate at an arcuate outer edge. An arrangement of flow paths is on each side and positioned to direct fluid filtrate toward the neck. The element is adapted to be interconnected with a plurality of similar sectors to form a disc-shaped filter and is adapted to be interconnected with a source for pressure differential so that when a filter medium is mounted thereon, filtrate collected therethrough will be directed to the neck for removal. The flow paths are in the form of a predetermined arrangement of channels in the outer surface of each side with the channels being of predetermined size to facilitate accommodation of different amounts of filtrate on different portions of the element as the element passes through the material to be filtered and to provide streamline and low turbulence flow through the channels with controlled direction and without significant back-flow between channels.
