摘要： A universal filter insert apparatus 10 for a water purifier includes a container insert 12 having substantially cylindrical or conical side walls 11 and an annular lip 17 at an upper portion thereof. A plurality of resilient sealing members 36 are stacked about the upper portion of the container. Each of the resilient sealing members includes (i) an internal sealing diameter 50 adapted to engage the container annular lip and (ii) a uniquely-shaped annular sealing flange 38 for engaging a filter receiving aperture 54 of a particular water purifier 52. At least one guide slot 22 extends along a portion of the bottom of the container insert. A granular filter medium is placed within the container insert and sealed therein with a container lid 30. The container lid has a plurality of apertures 34 sized to let water pass through and also includes a raised handle 32 for ease of insertion and removal of the universal filter insert. The annular sealing flanges are of various sizes and shapes in order to provide sealing engagement with apertures within a wide variety of water purifier housings.

摘要： The present invention involves a plate-shaped filter holder for use with a sterilizing container. The filter holder comprises a peripheral outer pressure rim, a central pressure region, a mounting device for fixing the filter holder on the sterilizing container and including webs between the outer pressure rim and the central pressure region which leave open breakthroughs therebetween. In order to prevent undesirable deformations in the filter holder, the webs extend at least partially in a direction which comprises a component in the peripheral direction.

摘要： A water treatment unit is disclosed which can be mounted directly on the faucet or tap of the user's sink and which contains one or more water treatment media and an operating valve which permits the selection of several operating modes including service, spray and stream modes. In the service mode the water is treated by at least one if not all of the various water treatment media contained in the unit housing after which the water is discharged from the valve of the unit for service use, and the service discharge may be adjusted to direct the treated water as desired by the user. The valve of the treatment unit includes a housing, a stationary member, a slide member and a rotatable switch member unit and may also be operated in a backflush mode in which water may be directed in the reverse direction through at least one of the water treatment media to regenerate that media. The volume of flow through the unit may also be sensed to measure the life of the treatment media to signal when they should be replaced.

摘要： A water treatment apparatus including a housing comprising multiple housing portions and a plurality of treatment sections disposed within the housing, each treatment section comprising at least one distinct particulate layer. The apparatus is designed so that no water pressure need be applied to force the water through the apparatus, as gravity pulls the water down through the filtering layers. Water may also be force fed through the treatment apparatus; when the water is force fed, the housing portions need not be vertically stacked, but may be configured in any suitable arrangement. The treatment sections are distributed through the various housing portions in logical groups to perform various kinds of filtering. The housing portions are detachable and sealably stackable in multiple configurations, thus passing water through more or fewer treatment layers, depending on the quality of the incoming water.

摘要： A septic system filter apparatus for filtering waste water as it travels from a septic tank to a septic field. The septic system filter apparatus includes a filtering system for filtering water from a septic tank for receiving waste material. A filtering apparatus comprises a first housing having a bottom wall and a top wall. The top wall is a removable lid. The first housing has a first inlet port and an exit port. The bottom wall has at least two supports thereon extending upward from an inner surface of the bottom wall. A second housing for holding filtering material has a removable lid thereon. The second housing has dimensions smaller than the first housing to fit into the first housing. A space is defined between the first housing and the second housing. The second housing rests on the supports above the inner surface of the bottom wall. The second housing has a second inlet port located generally adjacent to the first inlet port. The second housing has an upper chamber and lower chamber. A grill separates the upper and lower chambers. Filtering material covers the grill. An inlet pipe delivers fluid from the septic tank to the second housing. The inlet pipe extends through the first and the second inlet ports. An outlet pipe delivers fluid to a septic field from the interior of the first housing. The outlet pipe is fluidly connected to the outlet port in the first housing.
