Abstract: The present invention is directed to a replaceable lamp assembly for a point-of-use water treatment system (WTS). The lamp assembly includes first and second ends with respective sealed inlet and outlet openings associated with the ends. One or more conduits extend between the openings. A bulb assembly is positioned adjacent the conduit to irradiate liquid transferred in the conduit. A reflector assembly in the lamp assembly focuses radiation on the conduit. An enclosure surrounds the bulb and reflector assemblies such that lamp assembly becomes a generally closed pressure vessel.

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: The present invention is directed to a point-of-use water treatment system (WTS) unit (20) for filtering and treating contaminants in water. WTS unit (20) may include a first primary coil (74) located in a base unit (22) which inductively power a secondary treatment device such as a UV lamp assembly (24). A filter assembly (26) is used which has a filter block (90) and an inner sleeve (92) which extends inside filter block (90). Inner sleeve (92) defines a chamber in which the secondary treatment device (24) may be disposed. First and second valves and seals may be interposed between the filter assembly (26), secondary treatment device (24) and base unit (22) to allow the filter assembly (26) and secondary treatment device (24) to be independently replaceable. Secondary treatment device (24) may be a lamp assembly (24) which includes a condensing element (84) to condense mercury in a bulb in the arc path between filaments (444).
