Abstract: A system and method for concentrating aqueous beverages such as fruit juices, beer, wine, vinegar, tea, coffee, and the like in which a slurry of feed liquid and seed crystals is formed in a scraped surface heat exchanger of a first stage and supplied to a recrystallizer where larger crystals grow, the liquid in the recrystallizer being withdrawn with part recirculated to the heat exchanger of a succeeding stage. The slurry of larger crystals in the recrystallizer of the first stage is also withdrawn and the crystals separated in a wash column. The larger crystals grown in the second stage recrystallizer are supplied to the recrystallizer of the first stage where the seed crystals melt and reform on the larger crystals and the larger crystals from the third stage are similarly supplied to the recrystallizer of the second stage.

Abstract: The present invention utilizes a closed-type vessel comprising a filtering chamber, at least one perforated filter cylinder a portion of which is positioned within the filtering chamber, said filter cylinder being rotatable at any desired speed and having a filtering surface covered with a filter cloth, and a squeezing roll and sealing roll which engage with said filter cylinder through the filter cloth at all times to define a sealing and operating wall. Any sewage to be treated is supplied under pressure to the filtering chamber and filtered through the filter cloth at the filtering surface of the filter cylinder. Filter cake deposited on the filter cloth is continuously transferred to the outer periphery of the squeeze roll and then separated therefrom outside the filtering chamber by any suitable means such as a scraper.

Abstract: An apparatus for the separation of solids and liquids from a suspension has a hollow drum rotatably mounted about a horizontal axis. The drum wall is a screen made of a plurality of wires, preferably wedge-sectioned wires; spaced apart in a parallel arrangement and lying axially along the drum. Inlet means direct the suspension against the inner surface of the wall at an angle less than right angles, and preferably substantially tangentially to the inner surface, in a direction opposing the rotation of the drum. The separated solids remain within the drum and are extracted therefrom by suitable means.

Abstract: An apparatus for filtering raw water comprising a drum composed of disc-shaped end plates, horizontal member or members extended between the peripheries of the end plates, and a water-permeable filter cloth with a long pile stretched round the member or members to form a drum-shaped filter body. A rotating shaft supports the drum and the drum is submerged in a raw water conduit. A discharge pipe communicates with the inside of the drum. A hopper is located immediately below the filter body in the conduit and carries a pair of rolls on its upper edges for contact with the filter body. A drain pipe is connected to the hopper. The arrangement permits efficient removal of minute floating and drifting matter, such as plankton, from raw water, making possible a high rate of filtration with a very small space requirement.

Abstract: Disclosed herein is a filter sector for a vacuum disc slurry filter which is molded from an elastomer such as rubber and which is provided with a grid of reinforcing bands and a grid of ribs superimposed on the supporting bands to provide a supporting surface for the filter bag. The bands and ribs form slots and channels with a minimum surface area contacting the filter bag to provide increased vacuum communication with the filter bag and thus enhance cake build-up for more efficient separation of the liquids and solids. The use of rubber results in a lighter disc sector and minimizes abrasion on the filter bag and increases bag life.

Abstract: A disc filter assembly in which a plurality of filter discs are attached to a common shaft. The common shaft is a fabrication which has a central common mandrel. Saddles are rigidly attached to the common mandrel. Pipe segments are removably attached to the saddles. The pipe segments have at least one aperture which allows passage of filtrate from the filter to the pipe segments. The pipe segments are aligned and connected to form a continuous passage with an end piece which is mounted for rotation above a slurry container. The end piece has apertures therethrough aligned with the pipe segments. The end piece is operably connected to the pipe segments to form a continuous passage therethrough. The filter assembly is used to filter liquids from a taconite or other particulate slurry.
