Ultraviolet water purifier

Patent ·
OSTI ID:5760371

An ultraviolet water purifier has a number of ultraviolet lamps mounted in a cover which extends over the purifier and above the water. A parabolic reflector directs the rays of the lamps toward the body of water. The purifier is provided with a water inlet and a baffle adjacent to it having an opening at its base to compel the water entering the purifier to flow downward and then to flow through a filter. Air bubbles are trapped by a second baffle extending 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.
