    Abstract: The present invention discloses a method and apparatus for separating particles and dissolved matter from a produced water fluid stream. Specifically, the present invention includes a first pressure source which transports untreated produced water or contaminated aqueous fluid into a separator annulus with a filter element disposed therein. The untreated fluid is placed under appropriate pressure sufficient to produce turbulent flow, increased particle kinetics and/or cavitation allowing the desired fluid to penetrate and pass into and through the, filter media. The treated fluid is then transported to a collection tank. The contaminant matter retained by the filter media may be removed by the nearly instantaneous reverse pressurization of the separator annulus by a second pressure source thereby removing the contaminant particles away from contact with the filter media, and which may then be transported to a waste collection tank or a separator for further treatment.

    Abstract: A system using membranes for separating a desired component from a liquid or gas mixture to obtain a high-concentration organic solvent, such as in a plant for fermenting a biomass feedstock (e.g., corn or sugarcane) to produce ethanol. A module for removing water from the ethanol/water mixture comprises multiple vessels or elements connected together in series and supported by a frame. Each element includes a number of flow tubes concentrically enclosing a tubular membrane leaving an annular space between the membrane's outer wall and the flow tube's inner wall. The preferred membrane is a hollow ceramic (e.g., zeolite) tube. An ethanol/water vapor is passed through the space between the tube walls, and a vacuum is pulled on the membrane's hollow core. Water molecules selectively move through the membrane. Multiple passes through a series of elements having the concentric tubes and membranes gradually reduces the water content of the ethanol.

The discharge valve discharges a high-concentration salt water according to a third control signal. The control module performs first, second, and third flow rate control with reference to the flow rate Q1, Q2 and Q3 and the pressure P1.

  • Patent number: 8834727
    Abstract: Devices, processes, systems, and articles of manufacture adapted to treat contaminated fluid, such as organic wastewater, are described. These are described to include lifting contaminated fluids, treating contaminated fluids, or both, through gas application. In certain designs, gas, such as pressurized air, may be used to lift contaminated fluids, such as organic wastewater (i.e., water having contaminating organics of some kind, e.g. residential septic wastewater). In certain designs, gas, such as pressurized air, may also be used to treat fluids interfacing with the gas.

  • Patent number: 8808552
    Abstract: An apparatus and method to perform multiple filtration steps with a modular filtration apparatus and single cycle. A stackable modular filter cup has features to allow stacked cups to be separated without the need for substantial effort yet without diminishing the effect of vacuum assisted filtration. Each cup is formed with a slip seal segment and/or a series of substantially vertical channels or ridges on an inner or outer wall to reduce surface contact between nested filter cups.

  • Patent number: 8784668
    Abstract: In a regenerative dialysis system, in a method for controlling a regenerative dialysis system, and in a controller for a regenerative dialysis system, an embodiment of the system comprises an input pump that pumps fresh dialysate fluid into a dialyzer at an input rate. An output pump pumps used dialysate fluid from the dialyzer at an output rate. An ultrafiltration rate of the system is related to the output rate relative to the input rate. A sorbent cartridge filters the used dialysate fluid to generate the fresh dialysate fluid. A controller controls the ultrafiltration rate of the system in response to a flow rate of the dialysate fluid through the sorbent cartridge.
