CONCEPT:
Ultraviolet (UV) technology has been used for more than seven decades to eliminate disease-causing microorganisms, primarily in industrial and commercial applications. Ultraviolet water purification lamps produce UV-C or "germicidal UV," radiation of much greater intensity than sunlight. Almost all of a UV lamp's output is concentrated in the 254 nanometers (nm) region in order to take full advantage of the germicidal properties of this wavelength. UV light is capable of killing microorganisms such as bacteria, viruses, molds, algae, yeast, and oocysts like cryptosporidium and giardia. In practice, bacteria and viruses are the cause of most major waterborne pathogenic diseases. Of these enteric viruses, hepatitis virus and Legionella pneumophila have been shown to survive for considerable periods in the presence of chlorine, but are readily eliminated by UV treatment. Nevertheless, it is probably the most cost effective and efficient technology available to homeowners to eliminate a wide range of biological contaminants from their water supply. Recent testing has also shown that UV can be effective at destroying certain VOC's. Most importantly, it does not introduce any chemicals to the water, it produces no bi-products, and it does not alter the taste, pH, or other properties of the water. Accordingly, in addition to producing safe drinking water, it is not harmful to your plumbing and septic system. Further, it is easy and cost-effective to install and maintain without any special training
HOW IT WORKS?
Ultraviolet purification uses a UV light source (lamp) which is enclosed in a protective transparent sleeve (usually quartz). The lamp is mounted such that water passing through a flow chamber is exposed to the UV-C light rays. When harmful microbes are exposed to the UV rays, their nucleic acid absorbs the UV energy, which then scrambles the DNA structure of the organism. The cell is rendered sterile and can no longer reproduce. The cell is now considered dead and is no longer a threat.
APPLICATIONS:
UV treatment is an excellent choice to eliminate biological contamination from home drinking water & for industrial use, whether the feed water is municipal water system or untreated private system (well, lake water, etc.). Its sole purpose is to kill harmful biological contaminants, and therefore should always be combined with other forms of filtration (GAC / carbon block, KDF, or reverse osmosis) for reduction of heavy metals, chlorine, VOC's, and other chemical contaminants.
The germicidal energy of ultraviolet light destroys illness-causing microorganisms by attacking their genetic core (DNA). This powerful dose of UV light (wavelength of 253.7 nanometers) eliminates their ability to reproduce, and the organisms simply die. Disinfecting your water with ultraviolet light is exceptionally simple, effective and environmentally safe: our systems destroy 99.99% of harmful microorganisms without adding chemicals or changing your water's taste or odor. It is well proven, and it is the way of the future for water disinfection.
Many people object to the taste and smell of chlorinated water. But a greater concern is chlorine's ability to react with certain compounds that may be present in the water supply, to create by-products that have been linked to cancer (such as trihalomethanes, or THM's). By comparison, UV light is a natural process and does not produce harmful chemicals in drinking water. It's a safe, effective, and environmentally friendly disinfection method that is widely used for residential and industrial applications around the world.
