HOW ULTRAVIOLET DISINFECTION WORKS
Diagram is for Model 1000 on right >>
Just below the smallest wavelength of visible
light is a band called the Ultraviolet Spectrum. The "Germicidal Band" (UVc) of
the Ultraviolet Spectrum is 100 - 280 nanometers. Light at this wavelength destroys
microorganisms including bacteria and viruses. The WaterFixer operates at 253.7
nanometers, which is the most effective wavelength for germicidal action. Microorganisms
are destroyed by UV light on contact--this means that UV light must strike the organism
to be effective. Since UV light will not penetrate anything but a clear liquid, to
maintain clarity of your water the WaterFixer comes with two prefilters.
The first prefilter screens out larger size substances; the second filter screens out
remaining fine sediment plus chlorine and other chemicals while eliminating any existing
odors or unpleasant tastes in your water. It also filters parasites such as Giardia and
Cryptosporidium cysts. Inside the 304 stainless steel disinfection chamber, the
ultraviolet bulb is housed in a special quartz sleeve (tube) that allows the bulb to emit energy
at the 253.7 nanometers wavelength. The sterilizing power of the unit is defined by how
many microwatts can be applied to the water per second. At a flow rate of 4 gallons per
minute, the WaterFixer radiates significantly greater energy than the 16,000 microwatt
seconds per square centimeter required by the U.S. Public Health Service for UV
disinfection equipment. To ensure effectiveness of the ultraviolet component,
prefiltration is mandatory. Only approved filters should be used.
GREAT FOR BOATS & RVs
In the Great Outdoors, some of the
potential dangers of drinking
unsterilized water are: Chemical
Pollutants, Protozoa & Larger Parasites,
Bacteria and Viruses.
Boats and RVs may need to fill their
water storage tanks from questionable
sources. Holding tanks without
inhibitors may grow bacteria and impart
unpleasant tastes and odors while
endangering your health with unseen
viruses. The WaterFixer sterilizes your
water as it flows into your glass or
WE CARRY ALL Filters and
Other WaterFixer uses include farm and rural residents
who draw water from wells that may contain bacteria
from animal waste and surface contaminants; lake homes
that draw water directly from a reservoir, lake,
cistern, or well system; city residents who often find
their water distasteful (in some cases even dangerous)
due to strong chemical additives.
