  • Publication number: 20140346104
    Abstract: The invention relates to a ceramic filter element (22) for removal of liquid from solids containing material in a capillary suction dryer. The filter element comprises a ceramic substrate covered by a sintered ceramic microporous layer (31). The sintered microporous membrane layer is provided with coarse solid particles (71) of a particle size larger than a pore size of the membrane material layer (31) so as to form a textured surface (50) which prevents a filter cake from sliding off the surface of the filter element prior to the intended cake discharge.

  • Patent number: 8894847
    Abstract: A liquid reclamation assembly is provided for processing a lubricant or other liquid. The assembly includes a housing interior for receiving a filter subassembly. A manifold is in fluid communication with a discharge region of the filter subassembly, the manifold comprising a primary manifold passage for passage of source fluid and a series of draw ports. The cross sectional area of the primary manifold passage is greater than the total cross sectional area of the series of draw ports to create a venturi effect to draw fluid through the assembly. The filter subassembly includes a series of target filtration segment, each segment being designed for a specific reclamation process. An entry manifold governs and distributes the fluid to each of the target filtration segments. Results of an analysis of the fluid can be used to determine which target filtration segments are desired for processing the fluid. Valves within the entry manifold can direct the flow accordingly.

  • Publication number: 20140339142
    Abstract: A standalone aquarium filter with a filter cage having a hinged or detachable top cover and a filter bag. The filter bag is adapted to be filled with a filtering medium. The filter cage has sides with openings sized to allow water to flow substantially transversely through the at least one filter cage and through the at least one filter bag. The filter cage is adapted to stand alone on the bottom of an aquarium tank while the filled filter bag remains substantially vertical within the at least one filter cage. A bottom portion of the filter cage further includes a ballast to stabilize the position of the at least one filter cage. The plastic material is selected to be strong enough to prevent most aquarium fish from accessing the filter media bag and scattering filter media throughout the tank.

  • Patent number: 8877057
    Abstract: A filter for use with bulk filtration includes filters arranged in parallel flow and a manifold arrangement. The manifold arrangement has a first pipe within a second pipe. An inlet channel conveys unfiltered fluid to the filters, and an outlet channel conveys filtered fluid from the filters. The inlet channel is an interior volume between an outside surface of the first pipe and an inside surface of the second pipe. The outlet channel is an interior volume of the first pipe. Methods of servicing and filtering are provided.

  • Patent number: 8858789
    Abstract: A system for cleaning up an oil spill and recovering the spilled oil includes frames supporting superhydrophobic oil-absorbing nanowires. A first container supports the frames with the nanowires. A mixture of oil and water is pumped into the first container where the oil from the mixture is absorbed by the nanowires as water is separated from the mixture and deposited in the first container where it is then pumped therefrom. A second container supports the frames with the oil so-absorbed by the nanowires. The frames with the oil so-absorbed by the nanowires are heated whereby the oil so-absorbed separates from the nanowires and is deposited in the second container. The oil so-deposited in the second container is then pumped therefrom.

  • Patent number: 8858795
    Abstract: A fluid filter apparatus includes a first surrounding sidewall having inlet and outlet apertures, with first and second end portions, a cover attached to the second end portion and a domed end attached to the first end portion. Also included is a second surrounding sidewall with primary and secondary end portions, being co-axially disposed within the first surrounding sidewall, with a first environment interior disposed therebetween, a second environmental interior disposed within the second surrounding sidewall, and a third environmental interior disposed within said first surrounding sidewall. Further included is a primary strainer disposed between the first and second environments, a vane forming a helical channel within the first environmental adding a centrifugal velocity to the fluid to separate heavier fluids and particulates. Also, a secondary strainer is between the second and third environments, and a filter media is in a third environment.
