ABSTRACT:
Rotary disc filtration devices and filtration processes using those devices are disclosed. The devices have one or more fluid filtration gaps into which fluid to be filtered into permeate and retentate is placed. Each fluid filtration gap is defined by a disc and a filter, one of which rotates with respect to the other. The filter is carried on a filter support member. Fresh feed is introduced to each fluid filtration gap near the longitudinal axis of the shaft on which the discs are rotated. Holes through the disc in the active area of the disc, which is the area opposite the filter, counteract the tendency of the disc and filter to move towards one another.
