UltraViolet Systems

UltraViolet water filters disinfect your water supply. UltraViolet filtration kills bacteria, viruses, molds, algae and other microorganisms.

What is UltraViolet Water Filtration?

Ultraviolet light is a spectrum of light just below the range visible to the human eye. Ultraviolet light, at the germicidal wavelength of 253.7 nanometers, alters the genetic (DNA) material in cells so that bacteria, viruses, molds, algae and other microorganisms can no longer reproduce. The microorganisms are considered dead, and the risk of disease from them is eliminated.

Ultraviolet (UV) filtration is used as a pretreatment and/or post treatment step to kill or inhibit growth of microorganisms, remove ozone, chlorine and trace organics and reduce total organic carbon (TOC). During UV sterilization, the water is exposed at a controlled rate to ultraviolet light waves. The bacteria absorb the UV radiation energy, which destroys or inactivates their DNA, thus preventing the bacteria from reproducing. UV systems may reduce 99% of bacteria in the water.


How does UltraViolet Water Filtration work?

Ultraviolet (UV) disinfection uses a UV light source, which is enclosed in a transparent protective sleeve. It is mounted so that water can pass through a flow chamber, and UV rays are admitted and absorbed into the stream. The UV-C spectrum (200 to 280 nanometers) is the most lethal range of wavelengths for microorganisms. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses, the genetic material (DNA/RNA) is rearranged and they can no longer reproduce. They are therefore considered dead and the risk of disease has been eliminated.


What are the benefits of UltraViolet Water Filters?

It is proven scientifically that 85% of child sickness and 65% of adult diseases are produced by water-borne viruses, bacteria and intestinal protozoa such as Cryptosporidium and Giardia. Inappropriate water treatment can lead to heath problems - hepatitis B, tuberculosis, meningitis, typhoid fever, tricomoniasis, and cholera, glaucoma, gastrointestinal pain, salmonella, poliovirus, and diarrhea. In North America, E.coli O157:H7, an extremely dangerous strain of E.coli bacteria, infects more than 80,000 people annually. Fortunately, E.coli O157:H7 is easily inactivated by UV light.

Disinfecting your drinking water with ultraviolet light (UV) makes good sense. It's environmentally safe, it's well proven, and it's the way of the future for water disinfection requirements around the globe. UV water filtration can be applied to almost any water system, it adds no chemicals to the water, it wastes no water, UV is particularly effective with viruses, and is inexpensive to maintain.

UV disinfects water without adding chemicals, and therefore possesses some of the same benefits as distillation. It does not create new chemical complexes, nor does it change the taste or odor of the water, and does not remove any beneficial minerals in the water.

Ultraviolet light is a natural, cost effective, environmentally friendly disinfection process for use in homes where healthy water is a concern.
