  • Patent number: 8518250
    Abstract: An apparatus for separating liquids during agitation includes a support and a honeycomb cellular structure supported by the support. The cellular structure has a top and a bottom. It is formed from a plurality of enclosed cells, which limit and re-direct liquid movement in all directions so that agitation of the support has a negligible co-mingling effect enabling a liquid separation interface to be established within the cellular structure. Each cell has an inlet and an outlet, which are out of register creating a non-linear migration path from the bottom to the top of the cellular structure. A capture assembly is provided to capture less dense liquids after separation has occurred.

  • Patent number: 8475664
    Abstract: The overflow and underflow effluents of a conventional hydrocyclone are discharged into enclosed vessels, so that the operating pressure may be manipulated for each effluent independently of other operating parameters. Each of the effluent vessels is equipped with a source of pressurized gas to form a gas blanket over the effluent at a controllable pressure. Such variable pressures in each vessel, in combination with the pressure of the incoming feed stream, provide the necessary parameters to implement pressure-differential-ratio control, thereby improving the efficiency of separation.

  • Patent number: 8440087
    Abstract: A thickening tank has a peripheral overflow launder and a centrally disposed feed well. Feedstock slurry is fed to a mixing box which also receives supernatant liquid and is supplemented by flocculated material flowing into the interior of the feed well onto a distributor baffle plate. The supernatant liquid is delivered at a controlled rate from a receiving vessel formed by an upright cylinder provided at its lower end with an impeller of a lift pump which is operated by a controller positioned at the upper end of a vertical drive shaft extending axially through the receiving vessel. The feed well is surrounded by a second launder which is closed at its base and formed with a cup. The lower end of the receiving vessel is spaced from the floor of the cup to draw supernatant liquid exclusively from the second launder rather than from the thickener tank.

  • Publication number: 20130087514
    Abstract: First and second liquids are separated from mixtures thereof in a holding tank that holds quantities of the two liquids after they have been separated and a quantity of the mixture that has not been separated. A first transfer conduit receives a pressurized mixture of the first and second liquids which is discharged into the holding tank. A venturi passageway is located in the first transfer conduit. A liquid conductor has an entry opening positioned so that at least a portion of the entry opening is located within the quantity of the mixture that is held in the holding tank and an exit opening that is in fluid communication with the venturi passageway. The increase in the velocity of the pressurized mixture flowing through the venturi passageway and the accompanying reduced pressure causes the mixture held in the holding tank to flow through the liquid conductor into the venturi passageway.

  • Patent number: 8397921
    Abstract: A spraying means is arranged on the scum-flowing wall surface side of wall surfaces forming a scum inlet of a scum discharging mechanism. The spraying means sprays pressured water upward along the wall surface on the scum-flowing side from when a part of the scum inlet is submerged in water until the scum begins to flow into the scum inlet. As a result, even large lumps of scum exceeding 10 cm in thickness (diameter) may be lead smoothly into a pipe by the pressured water, and the amount of discharged water accompanying scum discharge may be reduced to 1/20 to 1/30 than by a conventional scum removing apparatus.
