Bacteria
The World Health
Organization says as much as 80% of all diseases are water borne. Organisms such
as: Bacteria, Mold Spores, Legionella, Algae, Protozoans and Viruses can all be
eliminated with Ultraviolet Light.
For many years, the
water treatment industry has used ultraviolet light to disinfect filtered
water. With the growing concerns of chlorine, ultraviolet light is an
attractive alternative for the following reasons:
*
You
can not over treat water with an ultraviolet light
*
There
are no harmful residuals added to the water
*
UV
light does not change the water's physical or chemical properties such as:
odor, pH, color or temperature.
*
UV
treatment is considerably less expensive to install and maintain
*
UV
treatment can be put on virtually any water supply.
How does UV
destroy microorganisms
 Ultraviolet
energy is germicidal. It kills germs or micro-organisms with high-energy light
which penetrates the organism's cytoplasmic or protective membrane. It shifts
electrons and attacks the DNA structure, preventing the microorganisms from
reproducing, rendering the cell lifeless. When bacteria and viruses are exposed
to the proper dose of UV energy, these organisms are harmless.
How
much UV energy is sufficient for disinfection
To destroy most bacteria, virus and
yeast, 10,000 microwatt-seconds per square centimeter (uw-sec/cm2) or less is
required. Germicidal Disinfection units are rated for a minimum dosage of 30,000
microwatt seconds per square centimeter.
According to the Department of
Health, Education and Welfare, the recommended minimum dosage for ultraviolet
equipment used in the disinfection process of filtered water is 16,000 uw-sec/cm2.
It should be noted, however, that UV
will not kill cryptosporidium or giardia.
