Abstract: A separator particularly useful in freeze concentration systems and apparatus, particularly multi-stage countercurrent systems for concentrating aqueous feed liquid, but useful for other kinds of separators as well. The slurry to be separated enters a vessel in which is mounted and rotated a cylindrical filter. The liquid passes through the filter to one outlet while the solids accumulate on the filter and are removed and directed to another outlet by a fixed scraper.

Abstract: An easily removable tubular filter assembly, such as from a cylindrical array of parallel filter tubes arranged between two spaced parallel circular plates, which array is immersible in a liquid to be filtered. Each filter tube comprises a central open-ended perforated rigid tube with flanged tubular bushings for each end, and a fabric tubular sock which surrounds the perforated tube and tucks in the ends of the tube around the outer flanges of said bushings. A flanged tubular ferrule snugly fits in the bushing at one end of the fabric-covered tube to hold the tucked-in sock in place and seal its flange into an aperture in a wall of a suction chamber which may comprise one of the parallel circular plates of the array assembly. The other end of each filter tube is closed by a plug which snugly fits into the other end bushing and holds the other tucked-in end of the sock in place, as well as supports that end of the filter tube in an aperture in the other spaced circular plate, identical with that plate forming the wall of the suction chamber. The outer end of this plug provides a seat for a compression spring which is compressed by a removable plate bolted to the adjacent apertured plate, which compressed spring urges all the filter tubes into sealing contact with the apertures in the suction chamber. Thus, by removing the outer bolted plate, which may cover, preferably not more than half of the apertures and filter tube ends, enables easy axial removal of its associated filter tubes from the array for replacement without further disassembly of the array.

Abstract: A rotary screen separator is described for separating liquids and solids from a slurry. The rotary screen separator includes a cylindrical straining screen rotatably mounted for rotation about a substantially horizontal axis. The separator has a drive for rotating the straining screen at a constant low speed. The separator has a slurry feed means mounted within the interior of the straining screen for spreading the slurry into a thin curtain and directing the curtain downward against a downward moving portion of the straining screen to direct the slurry against the inner surface to enable liquid to pass through the screen to the outer surface and to push the solid materials forward along the inside surface to clean the inside surface. A compression roller is freely mounted within the straining screen for rolling with the moving screen to compress the solid material against the inner surface to remove additional liquid. An auger is mounted axially within the straining screen to engage the solid material and move the material axially to one end of the separator for disposal.

Abstract: A water intake for example for taking cooling water for industrial installations from a river, a lake or the sea, has a sieve with a filter element and a recovery channel associated with the filter element for collecting and saving elements of the biomass which become stuck to the filter element. Electrodes are associated with the recovery channel 25 and are designed to induce an electrical field, at right angles to the recovery channel in the water to be tapped, so as to compel fish either to swim by themselves in the direction of this recovery channel or to allow themselves to be carried towards the recovery channel by a reverse water current induced at right angles thereto.

Abstract: Apparatus is disclosed for steam drying a cake of filtered solids formed on a disc filter element of a rotary disc vacuum filter where the disc filter element is mounted on a rotating means for rotation in a container, the lower portion of which includes a slurry tank and the upper portion of which includes a steam hood. The steam hood encloses a portion of the disc filter element in a steam chamber and includes a pair of sidewalls and a spine wall which joins the pair of sidewalls. A linear seal means is mounted to the pair of sidewalls of the hood to define a steam-retaining exit for the steam chamber through which the disc filter element rotatably moves, and includes two elongated flexible flaps which extend in a straight line from the spine wall into the slurry tank.
