ABSTRACT:
An ultraviolet water purifier having a plurality of ultraviolet lamps mounted in a cover extending over the purifier and above the water in the purifier with a parabolic reflector directing the rays of the lamps toward the body of water. The purifier is provided with a water inlet and a baffle adjacent thereto having an opening at its base to compel the water entering the purifier to flow directly downwardly and then to flow through a plurality of filter. Air bubbles are trapped by a second baffle extending downwardly from the cover to below the water level. Before the water is discharged from the purifier, a third baffle which is positioned in approximately the center of the purifier and of lower height than the body of water compels the water to flow to the surface and over the third baffle to be discharged at the end of the purifier opposite that of the inlet thereby exposing the water to the rays of the ultraviolet lamps for a maximum period and at the position at which the rays are most effective as a germicide.
