What is Ultraviolet?
Ultraviolet (UV) light from the sun has long been known for
its ability to deactivate microorganisms. However, it has
only been in recent years that equipment producing UV
light has been manufactured for residential use.
WARNING:
NEVER LOOK DIRECTLY AT A LIGHTED UV LAMP.
ULTRAVIOLET RAYS CAN BE HARMFUL TO EYES.
UV energy is produced by low-pressure mercury vapor
enclosed in a tubular lamp. While a UV lamp resembles a
standard fluorescent lamp, it is similar in appearance only.
Energy produced by the UV lamp has the ability to
destroy microorganisms that can live in water. There are
five major groups of microorganisms that are altered by
a specific spectrum of ultraviolet light: viruses, bacteria,
fungi, algae, and protozoa.
When these microbes are exposed to the proper amount
of UV energy, their DNA structure is scrambled, and they
are unable to reproduce. Since the cell is now sterile or
dead, it is no longer a threat.
PURA Systems
PURA recommends that all UV systems include pre-filters
to process the water before it reaches the UV lamp. This
will ensure that maximum UV exposure is achieved.
PURA Ultraviolet Water Treatment Systems are designed
for indoor use only.
PURA Systems are designed to provide complete water
treatment in a compact, easy-to-use package. Please fol-
low the directions in this Guide exactly when installing your
PURA System to ensure that it operates correctly.
