  • Patent number: 10598140
    Abstract: A system for increasing the efficiency of separating two liquids through filtration is disclosed. In a detailed example, water (both free and emulsified) is separated from diesel fuel, along with contaminants. The system has a filter medium attached to a support. The support has a tube structure that positions the filter medium away from the top plate. The filter can be positioned in a canister for removing emulsified water from the liquid. This canister can be used in a system to filter liquid stored in a tank that may contain water (emulsified and free) and/or debris. The system and method disclosed is particularly useful for removing emulsified water from diesel, such as ultra-low sulfur diesel (ULSD), bio-blended diesel, and diesel derivatives.

    Abstract: A well fluid particle screen assembly includes a base pipe having first and second pipe segments. First and second sets of perforations are located in sidewalls of the first and second pipe segments. First and second screens are mounted around the first and second pipe segments. A second pipe segment valve mounted to the second pipe segment has a closed position blocking well fluid flow through the second set of perforations. The second pipe segment valve has a pressure area acted on by a well fluid pressure differential. When reaching a threshold, the pressure differential causes the second pipe segment valve to move from the closed position to an open position. A retainer retains the second pipe segment valve in the closed position until the threshold is reached.

  • Patent number: 10241012
    Abstract: A method for separating plasma in a minute amount of a blood sample diluted with a blood dilution buffer is provided. When a blood dilution buffer is added to a minute amount of blood (about 20 to 100 ?L) so as to assay the biological blood components in the resulting diluted plasma, it is necessary to separately store and transfer the diluted blood cell component and the diluted plasma component. The present inventors found that it is possible to separate diluted plasma from diluted blood cells using a polymer gelling agent for plasma separation by means of putting a polymer gel for plasma separation in the container with a blood dilution buffer. In such case, diluted blood cells are transferred to the lower portion of the polymer gelling agent and dilute plasma is transferred to the upper portion of the same. Assay of the biological blood components using a minute amount of blood can be utilized for early detection of health status, diseases, and presymptomatic states.

    Abstract: The present invention provides a vacuum filter device including a filter body having two holders on opposite sides of a filter. Each holder contains a closed container in a fluid-tight, sealed relationship. The filter is retained by a compression sealing element that resiliently applies sealing pressure to the upper surface of the filter. The sealing element is maintained in place by a compression element formed of a ring that applies a desired compressive force to the sealing element. The compression element is bonded to a portion of the body to hold it, the sealing element and filter in place and under a compression seal. The invention also can provide for an alignment feature on the compression element that ensures the port is in alignment with the vent of the device. The device also includes a vacuum port communicating with the downstream side of the filter, and hence the filtrate container.

    Abstract: A filter system including a vacuum source for generating a vacuum flow and a container. The container includes an inflow port for receiving contaminated liquids and solids, a filter assembly for filtering contaminated solids from the contaminated liquids and an outflow port for delivering filtered liquids from the container. The vacuum flow proceeds through the container so that the filtered liquids are drawn through the filter assembly towards the outflow port. The contaminated solids receive vacuum pressure continuously to complete the filter process above the top filter.

  • Patent number: 8910799
    Abstract: Integrated membrane treatment systems for treatment of an aqueous solution. In embodiments, components, such as an MBR, are integrated with means to recover energy from the system, for example from an RO concentrate, to operate the other components. In embodiments including biological treatment, RO is integrated with other components, such as an MBR with the ROs ability to remove inorganic nitrogen enabling biological treatment to be performed with only partial nitrification and the MBR operated without active pH control. In embodiments, RO is integrated with a chlorine generator to convert chlorides present in the RO concentrate for an in-situ source of oxidizing biocides for disinfection purposes. Chloramines may be generated in-situ from residual ammonia and chlorides in the RO reject. In embodiments, carrier media is employed in a membrane tank to enhance removal of residual organics by the MBR and to also improve effectiveness of membrane scouring.

  • Publication number: 20140353231
    Abstract: The present application presents the development of a method for enhancing filtration capabilities of ceramic elements by chemically binding a hydrophilic compound throughout the porous structure of a ceramic element. An enhanced ceramic filter includes a ceramic element with chemically bound hydrophilic molecules. The enhanced ceramic filter is used in a system for the separation of non-polar compounds from aqueous mixtures. An aqueous mixture is passed through the enhanced ceramic filter, allowing water to permeate, and concentrate to exit the filter.

  • Publication number: 20140291223
    Abstract: The present invention relates to the method for preventing the liquid in the filtering plug-in card form dripping and a plug-in-card type liquid purifying and filtering device. The said liquid purifying and filtering device comprises the water pump, filtering cylinder and filtering plug-in card. In particular, at the top of the said filtering cylinder is equipped with the disassembled filtering plug-in card retainer. When the filtering plug-in card is taken out, such disassembled filtering plug-in card retainer is utilized to place the said filtering plug-in card, thus enabling such filtering plug-in card to leave the liquid level inside the filtering cylinder. In addition, it can set the disassembled top cap retainer for the said filtering cylinder. When the said top cap is disassembled, the disassembled top cap retainer is used to place the said top cap.
