  • Patent number: 9022225
    Abstract: Provided is a filtration filer with which a stable opening size during filtration is obtained, and which can be easily regenerated when clogged and used repeatedly. The filtration filter (10) comprises: a substrate stack wherein substrates (11) that have a through hole that penetrates from front to back are stacked; stoppers (15) that define the spacing between the substrates (11); and pillars (16) with a larger thermal expansion coefficient than the stoppers (15). The spacing between the substrates (11) at normal temperature is defined at least by the stoppers (15), and the spacing when heated is defined by the thermally expanded pillars (16). The gaps between the substrates (11) form the filtration surface that traps contaminants contained in the liquid that is being treated A.

  • Patent number: 8877048
    Abstract: A series of cascading basins is excavated along a sloped floodway typically established between adjoining agricultural fields. These basins address problems of stormwater runoff from agricultural lands and certain urban areas where runoff carries sediment, nitrogen, phosphorous and other pollutants into nearby streams, rivers and tidal waters, The cascading basin series begins with basin placement at a higher topographical elevation, followed by basin positioning downwardly along a natural or excavated floodway slope simulating a terraced effect. As upper basins are filled they spill over into basins therebelow. Angular features of basin exit grade and stormwater escape slopes retard egress of stormwater. A lowermost terminal basin includes sand berm, boulders, rip rap and other barriers to retain the polluted runoff. Basins may include vegetation, slag stone layers, and other pollutant treatment elements.

    Abstract: A solvent filtration and recovery system for filtration and recovery of a solvent-based liquid used in dry cleaning includes filtration tank having filter chamber with motor-driven spin filters which are selectively operated. A valve and conduit arrangement allows the liquid from dry cleaning to enter the filter chamber for filtering and flows out as filtered liquid while the spin filters are not rotating. The arrangement allows initial at least partial draining of the solvent-based liquid in the filter chamber after such filtration procedure. A recovery tank is in communication with the filtration tank through a main drain. A motor drives the spin filters during a recovery procedure, in which centrifugal force caused by the rotating spin filters for a predetermined amount of time removes by-product from the spin filters, which is drained off from the filtration tank. A reservoir stores the solvent-based liquid and receives the liquid from both the recovery tank and the filtration tank.

    Abstract: A device is disclosed for filtering a particle to be detected from a fluid. In at least one embodiment, the device includes a substrate and, applied above it, a protective layer, a channel being disposed between them for the purpose of receiving a fluid containing different particles. In at least one embodiment, the channel extends at least partially in a spiral shape between its inlet and outlet and on its internal wall contains a coating for attracting a particle type to be filtered, which coating is applied at least on the radially outside subsection of the internal wall of the channel. Owing to the laminar longitudinal movement of the fluid inside the channel a radially outward directed centrifugal force acts on the particles, with the result that per time unit more particles come into contact with the radially outside subsection of the internal wall of the channel than the radially inside subsection of the internal wall of the channel. The filter effect is reinforced as a result.

  • Publication number: 20100270217
    Abstract: A drainless reverse osmosis (RO) water purification system provides relatively pure water for on-demand dispensing, while recycling brine to a domestic hot water system. The drainless purification system includes a pre-filter catalyst cartridge for removing chlorine-based contaminants from a tap water supply upstream from an RO membrane. The catalyst is regularly refreshed by a high through-flow of water to a conventional cold water dispense faucet, thereby significantly prolonging the service life of the RO membrane. The RO membrane is incorporated into a multi-cartridge unit adapted for facilitated slide-out removal and replacement as needed. A control valve recycles brine from the RO membrane to the hot water system during pure water production, and recirculates tap water through the RO membrane when a pure water reservoir is substantially filled. The multi-cartridge unit may further include an air filtration system for providing a flow of filtered air.

The separation unit further comprises a third wall which constitutes a separation wall extending from the first end-wall towards the second end-wall and divides the inner chamber into a first and a second sub-chamber. An inlet is defined at the first side-wall and the first end-wall and a first outlet is defined at the second side-wall and the first end-wall. A passage is defined at the third wall and the second end-wall and a fluid path from the inlet which passes through the first sub-chamber and the passage and the second sub-chamber to the first outlet.

  • Publication number: 20090321362
    Abstract: The device (1) serves for the generation of a discrete liquid phase in a continuous liquid phase with a first or a second liquid. The two liquids coexist as separate phases, have different densities and permit a desired exchange of material. Provision is made to arrange the device in a container (9) which contains the second liquid forming the continuous phase. The device includes a distribution member (2), in particular a cylindrical tube, and a collection passage (3) for the first liquid in a horizontal longitudinal extent. The collection passage has an outlet side (4), a collection side (5) and at least one side wall (6) connecting the outlet side and the collection side. The side wall establishes a connection between the outlet side and a horizontal drip edge (7). This side wall has a shape and an inclination which enables the formation of a liquid film of the discrete liquid phase. For enhancing the stability of the Film, the side wall (6) can have a good wettability for the first liquid.

The primary and secondary filters are fluidly isolated from each other. The primary filter is configured for radial flow, and the secondary filter is configured for axial flow. The filter arrangement can be a top load arrangement or, in another embodiment, a bottom load arrangement. This combination is useable in any system that has a filter upstream of a pump (44) and a filter downstream of a pump (14). The example described is a fuel system. Methods of servicing include simultaneously removing the housing cover along with both the primary and secondary filters.
