    Abstract: Rotary disc filtration devices and filtration processes using those devices are disclosed. The devices (20) have one or more fluid filtration gaps (40) 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 (34). Fresh feed is introduced to each fluid filtration gap (40) near the longitudinal axis of the shaft (28) on which the discs (36) are rotated. Holes (66) through the disc (36) in the active area of the disc (36), which is the area opposite the filter (42), counter act the tendency of the disc (36) and filter (42) to move towards one another.

    Abstract: Pressure screening apparatus for screening a suspension of paper fiber stock employs a rotor (14, 15, 16) in which a single impulse or foil member (12) is carried or positioned to move along a discrete portion of the screen surface (10). This arrangement improves efficiency of operation of the pressure screen by reducing the rotational effect of the rotor (14, 15, 16) on the stock suspension being screened and by providing a less disturbed screening region through which the single foil (12) operates. Embodiments are shown in which a single foil (12) is combined, in screening apparatus, with multiple foils in accordance with the increase in consistency of the stock as it passes through the screen (10).

    Abstract: A high volume, self-cleaning filter unit (10) includes at least one cage support (18) with a downwardly angled surface having a direct path filter media (12) sealed thereto, with a suction source (14) to extract filtered fluid from the interior of the cage support (18). During operation of the filtering, particulates clog the filter media (12), and a backwashing (16) is effected by either backflushing with air or the fluid being filtered. Extremely high volumes of fluid can be filtered to a high degree, generally on the order of a few microns, in one step with a very economical filter unit (10). The downwardly angled surface holds the filter media (12) in such a position that a small mesh filter cloth is filtering a nominal size of particles out of the fluid. Oil is rejected by the filter unit (10) at a high rate, making this an effective oil/water separator as well.

    Abstract: A screen cylinder or plate with a screening surface (11) for separating accepts from rejects, the surface including a number of parallel macro grooves (22) and a number of parallel micro grooves (24) formed within each macro groove generally transverse to the flow direction. The macro grooves induce shear stress in the reject material preventing it from forming a mat on the screening surface. The micro grooves induce micro turbulence into the pulp at the screening openings (27) improving accepts flow through the openings. Each micro groove within a macro groove is located further away from the accepts surface (12) moving in the flow direction. The contour of each micro groove preferably includes an upstream wall (39), a sloped downstream wall (40), and a depression (41) therebetween. The screening openings are provided in the depression. It is possible to screen with a rejects rate of about 3-10 % at debris removal efficiency of above about 85 %.
