  • Patent number: 8025801
    Abstract: Simultaneous source-sink flow, or radial counterflow, is driven by a centrifugal pump disposed within a casing. Radially outward source flow of brine goes into a shrouding tank and concentrates while a radially inward sink flow of fresh water flows back over the pump to axial extraction. An axial pump drives sink flow and axial extraction. Convergent sink flow passes under an inductor to an axial exhaust port. Induced viscosity and inductive repulsion hinder the passage of brine in sink flow, so only fresh water can reach the axial exhaust port. Crystallization of scale-forming salts is aided by Joule heating from the inductor. Solvent and gases are continuously axially extracted in sink flow, favoring crystallization. Sodium chloride is cooled and crystallized in the shrouding tank. Brine comprising other salts flows out of the tank to treatment by suitable means. Thus brine is separated into fresh water, crystallized salt, and concentrated brine.

  • Patent number: 7757866
    Abstract: In an embodiment, axially-fed slurry can be continuously separated into clarified liquid, stripped gas, and thickened sludge in radial counterflow between counter-rotating coaxial centrifugal impellers. One impeller comprises an annular crossflow filter through which liquids are extracted. At the periphery of the impellers, where they are narrowly separated, the sludge is shear thickened into an extruded paste. Suspended solids in the feed pass over the surface of the rotating annular crossflow filter by the shear lift effect, and the vortex-wall interaction jets water radially inward from the periphery, dewatering the sludge. Evolved gases, oils, and fractions lighter than water flow radially inward to the impeller axis through radial vortices in a shear layer between the impellers, and are extracted through an axial exhaust conduit. Feed has long residence time so that separation is complete and continuous. Municipal wastewater, produced water, beverages, food, and scrubber sludge are discussed.

    Abstract: An improved method and apparatus for the removal of solid contaminants which utilizes at least one rotating mesh screen container designed to pass the food therethrough while trapping the solid contaminant. The rotation of the cylindrically-shaped mesh screen causes the food to pass through because of the centrifugal force. The addition of a second mesh or membrane-like placed around the first screen but rotated in the opposite direction is also utilized to trap solid contaminants which are large enough to be trapped by the mesh screen when it is not oriented so as to pass through the screens along its length. Different spacings in mesh and different rotation velocities are utilized to change contaminant screen characteristics.

  • Patent number: 5653879
    Abstract: A flattened end portion of flighting is added to the conventional auger flighting at the output end of an auger separator. A plug zone is created in the inner perforated tube between the flattened flighting and pressure end gates, which normally close the inner tube. The auger shaft extends beyond the flattened flighting to the end of the inner tube, forming a stub shaft which centers the auger in the inner tube when the plug zone is filled with material around the stub shaft. The material functions as a bearing to center the auger shaft. The material in the plug zone is pressed against the perforated inner tube, causing the bonded water to be removed. The flattened end portion flighting extends circumferentially approximately to around the auger shaft, adding an axial length of approximately 1/4 to 3/8 inch.

    Abstract: A centrifugal microstrainer includes a closed cylindrical vessel with a cylindrical screen within, both rotating about a hollow shaft forming a common central axis. Liquid-solid admixture introduced through the shaft is flowed radially outward subjected to centrifugal acceleration, and forced back through the screen under pressure with particles too large to pass the screen remaining on its outboard side. The centrifugal force applied by the rotation of the vessel acts on these larger particles pushing them away from the screen thus preventing clogging and permitting substantially continuous operation. The device may be operated as a classifier by providing a plurality of concentric screens of decreasing mesh size spaced outwardly from one another in conjunction with properly sized chokes.
