    Abstract: A water treatment apparatus includes 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.

  • Publication number: 20120055862
    Abstract: A portable, personal apparatus for treating drinking water comprises a generally tubular or cylindrical filter housing containing filtration media and water-permeable screen or mesh or felt or membrane or netting layer at the top and bottom ends of the filter. The design of the apparatus involves the bottle exterior and interior contouring to the filter and enables the efficient and rapid gravity flow of water in through the filter. The apparatus may be configured such that water is first passed through a top reservoir designed to receive water, followed by a porous mesh, followed by granular filtration and antimicrobial media agitated by turbulent motion of influent water, followed by a porous mesh before reaching a durable and reusable water containment vessel.

  • Patent number: 8128820
    Abstract: A liquid storage and dispensing device with a filter for removing minerals and a UV light source for killing pathogens existing in a liquid. A liquid is introduced into the device via the inlet. The liquid passes through the filter into a collector. The filtered liquid flows from the collector through a passage into a UV chamber. The UV light source emits UV rays through a UV transmissive wall into the interior portion of the UV chamber. Exposure to the UV light kills pathogens present in the filtered liquid. Substantially purified liquid can then be dispensed from an outlet.
