What is
ultraviolet?
Ultraviolet light is part of the light spectrum, which is classified
into three wavelength ranges:
- UV-C, from 100 nanometers (nm) to 280 nm
- UV-B, from 280 nm to 315 nm
- UV-A, from 315 nm to 400 nm
 |
What is
germicidal ultraviolet?
UV-C light is germicidal - i.e., it deactivates the DNA of bacteria,
viruses and other pathogens and thus destroys their ability to multiply
and cause disease. Specifically, UV-C light causes damage to the
nucleic acid of microorganisms by forming covalent bonds between
certain adjacent bases in the DNA. The formation of such bonds prevent
the DNA from being unzipped for replication, and the organism is unable
to reproduce. In fact, when the organism tries to replicate, it dies.

What are the
beneficial uses of germicidal uv?
Ultraviolet technology is a non-chemical approach to disinfection. In
this method of disinfection, nothing is added which makes this process
simple, inexpensive and requires very low maintenance. Ultraviolet
purifiers utilize germicidal lamps that are designed and calculated to
produce a certain dosage of ultraviolet (usually at least 16,000
microwatt seconds per square centimeter but many units actually have a
much higher dosage.) The principle of design is based on a product of
time and intensity - you must have a certain amount of both for a
successful design.
Here are just a few of the applications...
Drinking Water
- under sink installs & water vending machines
- aircraft, boats & recreational vehicles
- water wells & water cisterns
- swimming pool & hot tubs
- farms, ranches & trailer parks
- schools & hotels

How do
ultraviolet purifiers work?
Atlantic Ultraviolet Corporation's purifier units contain one or more
germicidal ultraviolet lamps. The Ster-L-Ray™
germicidal lamp produced by Atlantic Ultraviolet Corporation is a short
wave low pressure mercury vapor tubes that produces ultraviolet
wavelengths that are lethal to micro-organisms. Approximately 95% of
the ultraviolet energy emitted is at the mercury resonance line of 254
nanometers. This wavelength is in the region of maximum germicidal
effectiveness and is highly lethal to virus, bacteria and mold spores.
Therefore, the water or air that passes through the chamber is exposed
to the germicidal uv light and the genetic material of the
micro-organism is deactivated, which prevents them from reproducing and
renders them harmless.
