How does UV Disinfection work ?
When bacteria, viruses, and other
microorganisms are exposed to
germicidal UV light at a particular
wavelength (253.7 nanometers) their
reproductive capabilities are
destroyed, which means that they are
inactivated and no longer pose a
threat to human health.
Ultraviolet disinfection's systems
channel water past submerged lamps
that emit lethal doses of UV energy,
destroying any pathogens. The
strength of a dose is a product of
the UV light intensity and exposure
time. Not only is it safe and highly
effective, UV does not change the
taste, color, or odor of water. It
simply removes the risk of illness
caused by microbial contamination,
making water safe to drink or use
commercially.
The Advantages of UV Disinfection
» More effective against viruses
than chlorine.
» Environmentally and user friendly,
no dangerous chemicals to handle or
store, no risks of overdosing.
» Low initial capital cost as well
as reduced operating expenses when
compared with similar technologies
such as ozone, chlorine, etc.
» Immediate treatment process, no
need for holding tanks, long
retention times, etc.
» Extremely economical, hundreds of
gallons may be treated for each
penny of operating cost.
» No chemicals added to the water
supply - no byproducts, (i.e.
chlorine + organics =
trihalomethanes).
» No change in taste, odor, pH or
conductivity nor the general
chemistry of the water.
» Automatic operation without
special attention or measurement,
operator friendly.
» Simplicity and ease of
maintenance, periodic cleaning, (if
applicable), and annual lamp
replacement, no moving parts to wear
out.
» No handling of toxic chemicals, no
need for specialized storage
requirements.
» Easy installation, only two water
connections and a power connection.
» Compatible with all other water
processes, (i.e. R.O., filtration,
water conditioning and softening).
