ABSTRACT:
Water purification apparatus provides an elongate ultraviolet lamp extending into a surrounding hollow tube capable of passing ultraviolet light. The lamp and tube are surrounded by a housing, with water inlet and outlet, which provides an annular flow path around the hollow tube through which water may pass for exposure to ultraviolet light. An ultraviolet reflective surface in the annular flow path reflects ultraviolet rays through the water. A unique seal is provided around an open end of the hollow tube to seal the lamp from water in the housing.
