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). |
