  • Patent number: 9428406
    Abstract: An energy efficient membrane based desalination process, which utilizes an osmotically driven energy recovery sub-process. Energy recovery sub-process involves the extraction of water from low salinity first aqueous solution by using a high salinity content, pressurized second aqueous solution to draw the water from first aqueous solution across a semi-permeable membrane. High salinity content, pressurized second solution can be used to generate osmotic pressure on the low salinity content first solution to drive water from first solution to the second solution with respect to chemical potential differences. The process also harvests the Gibbs free energy of mixing in terms of pressure conservation in the second solution, while the volume of second solution is increasing by the drawn water from the first solution.

  • Patent number: 8871062
    Abstract: An apparatus and method are disclosed for controlling the thickness of a flowing, laminar fluid film. The film flow may be gravity-induced or the result of an alternative force. The fluid is deposited on an upper end of a flow surface where a relatively thick layer of the film forms. The film flows over a fluid dispersal region where the surface area is rapidly expanding, which results in rapid thinning of the film thickness. The fluid then flows over an active region where the surface area is designed to control the fluid film thickness. For example, in some applications, it may be desirable to maintain an approximately constant film thickness as the fluid flows over the active region of the surface. The geometry of the flow surface is used to obtain the desired control over the fluid film thickness. The flow surface is the outer surface of a solid with a closed upper end and a lower end that may be open or closed.

The multi-dentate ligand bonds with the cation to form a non-scaling ionic complex; and the aqueous solution with the ionic complex is used in a process that produces substantially pure water from the aqueous composition, where the cation, absent formation of the ionic complex, is subject to scaling. The pH of the aqueous composition (or a brine including components of the aqueous composition) is then reduced to release the cation from the multi-dentate ligand; and the multi-dentate ligand, after the cation is released, is then reused in a predominantly closed loop.

  • Publication number: 20140246388
    Abstract: A method and a plant for the treatment of water or wastewater having impurities by filtration of the water through two granular media filter stages of the moving bed type operated in series. The method includes the steps of feeding the water/wastewater as a first influent to first stage granular media filters; filtration of the first influent in the first stage granular media filters to produce a first effluent; feeding the first effluent as a second influent to second stage granular media filters; and filtration of the second influent in the second stage granular media filters to produce a second effluent. The second stage granular media filters are operated with intermittent washing of the granular filter media.

  • Publication number: 20140238938
    Abstract: An energy efficient membrane based desalination process, which utilizes an osmotically driven energy recovery sub-process. Energy recovery sub-process involves the extraction of water from low salinity first aqueous solution by using a high salinity content, pressurized second aqueous solution to draw the water from first aqueous solution across a semi-permeable membrane. High salinity content, pressurized second solution can be used to generate osmotic pressure on the low salinity content first solution to drive water from first solution to the second solution with respect to chemical potential differences. The process also harvests the Gibbs free energy of mixing in terms of pressure conservation in the second solution, while the volume of second solution is increasing by the drawn water from the first solution.

  • Patent number: 8801928
    Abstract: A fuel supply device (1), particularly for an internal combustion engine (6), is equipped with a particulate filter and a water trap. In order to improve the separation effect, while simultaneously reducing the separation material that is required, it is proposed to configure the water trap (5, 8, 30) as a separate component connected downstream of the fuel filer (4) and to provide it with a first separation stage made of coalescent material and a second separation stage made of hydrophobic material, and to dispose the separation stages such that between them the fuel is diverted.

  • Publication number: 20140209526
    Abstract: The present invention provides, in at least one embodiment, an upflow bioreactor removes trapped gases within the bed that effect water flow and a downflow bioreactor removes carbonaceous compounds and retains the particulate elemental selenium. The system integrates biological selenium reduction with biological filtration (via the downflow bioreactor) and an optional membrane filtration. The membrane filtration removes residual selenium and other particulate matter, which would get into the effluent. In one embodiment, the novelty of the invention is the utilization of an upflow bioreactor followed by a downflow bioreactor applied to selenium removal.

  • Publication number: 20140209525
    Abstract: In a water purifier, a flow system includes a first channel in which liquid is filtrated in at least one of a first filter tank and a second filter tank, a second channel in which the liquid is filtrated in the second filter tank and the first filter tank is washed, and a third channel in which the liquid is filtrated in the first filter tank and the second filter tank is washed. A switching lever actuates valve mechanisms to perform switching among the first, second, and third channels such that the channels are selected cyclically in order of the first channel, the second channel, the first channel, the third channel and the first channel. The valve mechanisms work with operation of the switching lever.

  • 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.

    Abstract: A filtering apparatus that sucks liquid in hollow portions (10) of the filtering elements (1) via suction pipes (3) so that liquid passes the filtering elements and is filtered. Each suction pipe has suction holes (4) connected to the hollow portions. The suction pipes are inserted into through holes (2) of the filtering elements. The filtering elements are arranged side by side and connected to the suction pipes. A ring-shaped packing is interposed between the filtering elements, and water-tightly seals the clearance between the filtering element and the suction pipe.
