Ultraviolet
(UV) technology is more effective than chemicals in destroying certain
waterborne contaminants without altering the taste of water.
Ultraviolet (UV) light
has been used to disinfect water supplies for more than 75 years.
Municipalities sometimes use UV instead of chlorination for
disinfection to avoid the byproducts that chlorination may produce in
the treated water supply. The primary advantage to UV treatment is that
it disinfects water without the use of chemicals.Treating water
supplies by the use of UV disinfection is not only more effective than
traditional treatments, but it is also an environmental responsible way
of treating water. Plus, UV does not alter water chemistry and its
constituents, such as pH, taste, odor, or color.
INEFFECTIVE AGAINST: It does not kill Giardia Lamblia Cysts or Cryptosporidium Parvum Oocysts,
which must be removed by filtration or distillation. UV is not
recommended if the untreated water has a coliform content exceeding
1,000 total coliforms or 100 fecal coliforms per 100 milliliters.
It is
important to note that, although UV is an effective disinfectant,
disinfection only occurs inside the unit. No disinfection occurs beyond
the treatment unit to kill bacteria that survived or were introduced
after UV treatment. If residual disinfection is necessary, chlorination
may be necessary in addition to or as an alternative to UV.
