Ultraviolet Water Purifiers
If you are looking for a system that can
purify your water without using chemicals,
you should consider installing an ultraviolet
water purifier. Ultraviolet light is part
of the light spectrum; ultraviolet light
with wavelengths from 100 to 280 nanometers
is germicidal, meaning that it destroys the
DNA of bacteria, viruses and other pathogens.
By exposing the microbes in water to the
right dose of ultraviolet light for the correct
amount of time, water can be inexpensively
purified in an easy to maintain system.
Ultraviolet light can be used
to purify household
water used for drinking, ice
making, cooking,
bathing, and washing. It is especially
useful
where water supplies depend on
wells or cisterns.
It can be used on aircraft, boats
and recreational
vehicles, for swimming pools
and hot tubs,
and for aquariums. If you are
thinking of
buying an ultraviolet water purifier,
consider
the following:
- Purifiers made from stainless steel will
last longer than those made from plastic,
as the ultraviolet light damages the plastic.
Also look for purifies with processing chambers
that are easy to drain in place.
- Better units have a light that glows to show
that the ultraviolet germicidal
lamp is on.
This lamp must be periodically
replaced.
Look for those that last for
about a year
and that are easy to replace
when necessary.
The easiest systems do not
require any tools,
and replacement of the lamp
can be accomplished
in less than five minutes.
- Ultraviolet light will not remove foreign
particles from the water. For this, you will
need some form of filtering.
Systems that come fully assembled and that
have been pressure tested are the easiest
to install. Check to make sure that the system
meets U.S. Public Health guidelines before
purchasing. |
