  • Patent number: 8945394
    Abstract: Disclosed herein are systems and methods for removing fine particulate matter from a fluid, comprising a separator that separates an inflow fluid stream into an overflow fluid path and an underflow fluid path, where the underflow fluid path is treated with a tethering material that attaches to the coarse particulate matter to form tether-bearing anchor particles and where the overflow fluid path is treated with an activating material so that the activating material interacts with the fine particulate matter to form activated particles. After these treatments, the underflow fluid path containing the tether-bearing anchor particles is commingled with the overflow fluid path containing the activated particles, so that a removable complex is produced that can be removed in a settling facility, thereby removing the fine particulate matter from the fluid.

  • Publication number: 20140305883
    Abstract: A system to permit separation of liquid and solid refuse in a single trash bin receptacle to facilitate the reliable sanitary disposal of such mixed items is provided. The overall system includes a trash receptacle device for deposit and separation of liquid and solid refuse including a reservoir for separated liquids as well as an easy-to-use and -operate liquid removal component, and a removable thermoplastic, flexible collection bag with appropriately located openings that allow for fluid transfer via gravitational forces and yet still retains suitable dimensional stability to collect and retain substantially all deposited solid refuse during further transport. Such a new system is particularly useful in retail settings wherein quick clean-up of patrons' refuse is necessary without the requirement for inefficient separation of liquid and solid items by hand. Such a viable, reliable and effective liquid/solid separation bag as well as the method of use thereof is encompassed herein.

  • Patent number: 8851296
    Abstract: This invention relates to a blood processing filter including a band-shaped first seal part that seals an inlet-side flexible container of the blood processing filter and a filter element of the blood processing filter so as to surround an inlet port, and an annular second seal part that seals at least the inlet-side flexible container and an outlet-side flexible container and is formed surrounding the first seal part at a position that is closer to an outer edge than the first seal part. A valley part corresponding to the first seal part is provided on an outlet side of the filter element. An outlet opening that communicates with an inside of the outlet-side flexible container is formed in the outlet port. At least one portion of the outlet opening is arranged so as to overlap with the valley part.

  • Patent number: 8852443
    Abstract: Various “no filter, no run” fuel filtration designs are described that include a variable restriction orifice (VRO) designed to vary the amount of fluid, for example fuel, that reaches a fluid outlet. The VRO has a fully open position at which a maximum non-zero fluid flow is permitted, and a fully closed position at which a limited amount of fluid can flow to the outlet. In the case of diesel fuel, the amount of fuel flow permitted at the fully closed position provides lubrication of downstream fuel system components, for example the fuel pump, but is insufficient to permit engine operation.

  • Patent number: 8852440
    Abstract: A filter unit comprising an inlet (12) and an outlet (13) for a flow medium to be filtered, a first filter cartridge (14) having a first filter element, a second filter cartridge (15) having a second filter element, and a switching device (16) which allows alternating filter operation of the first or the second filter cartridge (14, 15). It is proposed that the first filter cartridge be a main cartridge (14) with a fine first filter element and the second filter cartridge be an auxiliary cartridge (15) with a coarse second filter element. The pressure loss in the auxiliary cartridge (15) is set to the same threshold value as a contaminated main cartridge (14), at which the differential pressure switch triggers an alarm such that during changing of the main filter, the alarm continuously sounds and is only switched off after changing the filtering back to a fine filtering operation.

  • Publication number: 20140287156
    Abstract: Membranes of the invention comprise a hybrid silica film on a organic polymer support. The silica comprises organic bridging groups bound to two or more silicon atoms, in particular at least 1 of said organic bridging groups per 10 silicon atoms. The membranes can be produced by dry chemistry processes, in particular plasma-enhanced vapour deposition of bridged silane precursors, or by wet chemistry involving hydrolysis of the bridged silane precursors. The membranes are inexpensive and efficient for separation of small molecules and filtration processes.

    Abstract: The present invention includes a gravity filter assembly which includes at least one filter media positioned about at least one water inlet pathway. The gravity filter assembly also includes a base. The base has an engagement mechanism which is configured to releasably engage a filter media facing side of a liquid impermeable shroud when a liquid impermeable shroud is positioned over the filter media. The base is sized to fit within an outer perimeter defined by at least one perimeter side wall of the liquid impermeable shroud. Moreover the base includes a top cap section having an outer surface and a filter media facing surface. The filter media facing surface receives the top surface of the filter media. The filter media, base, and top cap section are configured to be removed and replaced without the use of tools.

  • Publication number: 20140263085
    Abstract: A continuously-operable flow stream processing system and method has two or more fluid processing media arranged in a fluid conduit network to provide alternate flow paths for a flow stream to be processed (e.g. filtered). Valves and other flow control devices, e.g. controller module and sensors, are used to redirect the flow stream from one or more service-needed fluid processing media to service-ready fluid processing media without taking the system offline to remove, repair, replace, clean in situ, or otherwise service the service-needed fluid processing media, so that the system may operate continuously to process the flow stream without stoppage. Redirection into alternative flow paths and media may be automatically implemented based on a predetermined threshold or trigger condition, such as may be detected by sensors directly or indirectly monitoring media condition.
