Water display system with germicidal light source

An odor-reducing water display system includes a reservoir, a pump for removing water from the reservoir, a conduit in fluid communication with the pump for returning the removed water into the reservoir, and a germicidal light source positioned for directing radiant energy toward the water to consequently decrease microbes and their accompanying odor that might be present in the water.

This invention relates to water screen methods for supplying a nice visual or perceptible encounter to observers, and more especially to a water screen system using a germicidal light source of removing contaminants or scents fromwater or other fluids which might be circulated through the water screen system.

Water screen systems, like water fountains, waterfalls or so on, have been used in gardens and similar outdoor locations, as well as in indoor locations on a typically much smaller scale. As revealed in FIG. 1, a conventional waterdisplay system 2 includes a reservoir 4 to holding a quantity of water 6, a pump 8 located within the reservoir in fluid communication with the water 6, and also a conduit 10 having an inlet end 12 in fluid communication with the pump 8 and a socket end 14that is placed over an upper surface 16 of the water 6 in the reservoir. In use, the pump 8 draws in water 6 from the reservoir 4, compels it up throughout the conduit 12 and out through the socket end 14 in which it falls back into the reservoir 4, asrepresented by arrows 18, to be recycled again through the pump and conduit. More complex versions of fountains can circulate the reservoir water through many pools or terraces located at different heights to create both visually and audiblypleasing consequences. During flow of the water, but it may be aerated and thus come in contact with airborne contaminants, such as mold spores, bacteria, viruses and/or other germs. Over time, these microbes may influence the water qualityand/or produce unpleasant odors. Even though these microbes may be controlled through application of chemicals to the water from the reservoir, like chlorine or alternative anti-microbial solutions, the compounds themselves may create unpleasant odors.

Accordingly, it might be desirable to offer a system and way of improving the water quality in water display systems, while reducing or eliminating the need for chemicals and their consequent odor generation.
