How does a
Ultraviolet Water Puification System Work?
water purification lamps produce UV-C of much greater intensity than
sunlight. Almost all of a UV lamp's output is concentrated in the 254
nanometers (nm) region. The lamps are mounted such that water, passing
through a flow chamber, is exposed to the UV-C light rays. UV light
works by attaching the genetic core (DNA/RNA) of bacteria and viruses,
destroying their ability to function and reproduce.
process is simple but effective, destroying 99.99 percent of harmful
microorganisms without adding chemicals to the water. The cell is
rendered sterile, can no longer reproduce, is considered dead and is no
longer a threat.
Its sole purpose is to kill harmful biological
contaminants, and therefore should always be combined with other forms
of filtration (GAC / carbon block, KDF, or reverse osmosis) for
reduction of heavy metals, chlorine, VOC's, and other chemical
For a UV
to work effectively
the water must be pre-filtered to exclude any particles larger than 5
microns (nominal) in size. This assures that particles large enough to
block the UV light do not pass through the system. If they do they can
act as a shield between the microorganism and the UV light – protecting
the microorganism and allowing it to pass into the product water
unharmed and alive.
for Ultraviolet Water Purification Systems
19 million American households and cottages rely on private wells. Tens
of thousands more rely on lakes, streams and other surface water
sources. Unfortunately, not all of them have a UV purification system
protecting thier families from harmful microorganisms.
nation-wide study exists, but some smaller scale studies have found
40% of wells in any given region suffer from E. coli and/or coliform
bacteria at any given time not to mention the countless other
microorganisms that may be in a water supply.
