Abstract: The present invention relates to a point-of-use water treatment system unit (10). The unit (10) includes a filter housing assembly (60) having a filter tank assembly (66) and a closure (64) which utilizes a handle (152) and cammed reciprocating lock blades (146, 150) to secure the closure (64) to the filter tank assembly (66). A UV tank assembly (300) includes a planar baffle plate (322) and a vaned baffle plate (324) to induce plug flow about a UV lamp assembly (280). The UV lamp assembly (280) is used which simultaneously electrically and sealingly mounts to UV tank assembly (300) and electrical cap assembly (290) using a bayonet mount. A bi-planar manifold assembly (40) is used to interconnect components of the WTS unit and to provide an envelope for accommodating a water pipe assembly (34). The bi-planar manifold assembly (40) enhances the compactness of the design of the WTS unit (10).

Abstract: A point of use water purification system for home use is provided comprising a carbon block filter housed in a self-contained disposable pressure vessel for removing particulates and organic contaminants from water. The filter is provided with a pore-size distribution, a binder and a flow path which optimizes filtration performance and enhances microbiological kill rates obtained in a source of radiant energy which is used to kill microorganisms in the filtered water. The source of radiant energy comprises an ultraviolet discharge lamp having an elongate central axis and a diverter for providing a spiral plug flow of water about the discharge lamp. A flow regulator adjusts flow through the system for varying line pressure conditions to ensure adequate exposure of microorganisms to ultraviolet energy. A lamp control circuit conserves power and optimizes ultraviolet output.

Abstract: An apparatus for the treatment of potable water having a substantially cylindrical pressure vessel which houses an ultraviolet light. The pressure vessel is in fluid communication with a filter stage which filters the water before treatment by the ultraviolet light. An ultraviolet lamp assembly sealed within a light permeable sleeve and having a single end cap provided with electrical terminals at one end only is disposed in watertight fashion within the pressure vessel. Downstream from an inlet to the pressure vessel is a deflector/baffle assembly provided to regulate the flow pattern and flow rate of the water within the pressure vessel thereby providing a uniform flow rate to achieve optimum kill rates of bacteria and other living organisms by exposure to the ultraviolet light. The ultraviolet lamp assembly is secured within the pressure vessel by a threaded closure nut which is easily secured or removed by hand.

Abstract: A measuring scoop with molded reusable fit clip is disclosed. The measuring scoop includes a bowl with a scraping lip or shoulder used for more effectively lifting product into the bowl, an elongated handle which is integrally mounted on said bowl and a reusable fit clip on the free end of the handle, which clip is used for sealing closed a bag of product. The design of the handle as well as the design of the reusable fit clip extends the life of the molded friction fit clip by improving the clipping force as well as the clip's resistance to deformation from applied stress.

Abstract: A self-contained, disposable water filter cartridge for a water treatment system for treatment of potable water has one-way ball check valves at the water inlet and water outlet to the cartridge. The generally cylindrical water filter cartridge is generally spherical on one end while substantially planar on the other end and is of a welded plastic construction. Asymmetrical lugs radially disposed about the periphery of the planar end are adapted to mate with an apertured deck of a water treatment system.

Abstract: A pressure vessel of the type used in domestic water purifying systems for the filtering of potable water, wherein an uncompromised, spherically ended cylindrical pressure vessel housing is provided which is manufactured of a very strong high quality resin and comprises two detachable major sections sealed with an O-ring and secured together through provision of a threaded annular collar; quick connect type plumbing fitments are provided at an inlet port and an outlet port of the pressure vessel housing requiring no tools to facilitate the removal and attachment thereof; a decorative plastic shell manufactured of less expensive resin is provided to encase the pressure vessel to provide structural stability and which can be fabricated to also provide aesthetic flexibility with regard to shape and color and may also provide a compartment for incorporating an electric flow meter.
