Throughout most of the developed
countries in the world, there are standards and regulations governing drinking
water. In America, we rely on the 1974 US
Environmental Protection Agency’s Safe Drinking
Water Act (SDWA), which is a federal law designed to protect public
drinking water supplies throughout the country. Under the SDWA, the EPA sets
standards for drinking water quality, and with help from its partners,
implements various technical and financial programs to safeguard our drinking
water.
While drinking water is essential to
human survival, only 2.5% of the earth’s water is drinkable and only 1% clean
enough to drink. In addition as the world
population increases, so does the demand for clean drinking water. The Centers for Disease Control and
Prevention states that, “Water, sanitation and hygiene has the potential to
prevent at least 9.1% of the global disease burden and 6.3% of all deaths.” They add that the impact of “clean water technologies on public health in the U.S. is
estimated to have had a rate of return of 23 to 1 for investments in water
filtration and chlorination during the first half of the 20th century”.
Today, we also recognize the
importance of providing our communities with safe drinking water that in the
process of purifying it does not further harm the environment. With more than 156,000 municipal drinking
water systems in the U.S. alone that serve 90% of our population, the methods
we use to treat water are critical. This is why germicidal UVC water
purification is quickly becoming an effective alternative to chemical
disinfection.
Unlike traditional chemical treatment,
UVC light disinfection has the advantage of effectively eliminating
cryptosporidium and giardia bacterium. Another
benefit to germicidal UV water purification includes the fact that biological
contaminants cannot build resistance to UV light. Also consumers like the fact that the process
does not alter the taste, odor or pH value of the water.
Germicidal UV water purification requires
only a short radiation time, ease of use and minimal maintenance as well as low
operating costs. Furthermore, while germicidal UVC light does not entirely replace
chemical disinfection for non-point-of-use, it does significantly reduce the
need for chemicals. Once water leaves
the irradiated area, the UVC method has no disinfection residual to protect it
and supplemental chemicals are required to protect water sitting for days in
pipes before it is consumed. See our website to learn more about our line of cost-effective germicidal lamps.

in the U.S. and our strategic partner in Europe, LightTech represent the leading high-tech
designers and manufacturers in the lamp industry today. Our products are used world-wide in a
multitude of applications and industries such as our UV air treatment systems
that provide industries a way to disinfect and improve the quality of air
without the need for toxic chemicals.
