ADVANTAGES OF UV OVER CHLORINE
2. Elimination of “Chlorine Smell”
Chlorine exists in both a “Free state”, and a combined state in pool water. The Free
chlorine is the chlorine that is available to oxidise organics and kill bacteria. The
Combined chlorine is chlorine that is combined, or “locked up”, with nitrogen-
ammonia compounds to allow the formation of Chloramines.
Chloramines are responsible for the chlorine odour that is normally present in a
“chemical only” treated pool. These chloramines exit the pool water in the form of
an off-gas that is not only unpleasant to the smell but has also been shown in tests
to cause skin, eye and respiratory problems, especially to asthmatic persons or
persons with other breathing difficulties.
Thus when Chlorimines are eliminated the “chlorine smell” disappears. UV has the
ability to produce a photo-oxidation effect that destroys chloramines and other
toxic by-products of chlorine. This results in much lower chlorine requirement for
bacterial control and greatly improves water and atmospheric conditions.
3. Hazardous Materials
When you add chlorine to a pool, extreme care must be taken not to overdose the
pool water and cause harm to the bathers. UV has the advantage over Chlorine in
that UV does not add any chemical to the pool water and cannot be overdosed.
4. Reduced Chlorine Levels
A reduced amount of chlorine (70% to 85% reduction on normal usage) is still
necessary to oxidise the organics and for sanitising wetted areas such as in the
pool piping or filter. This level of chlorine is harmless.
5. Immediate Killing of Micro-organisms
While chlorine requires a long retention time of 20-45 minutes to sanitise, UV
sanitises the pool water in 1-3 seconds of exposure. This occurs during all
operation time of the pool circulation system.
6. Algae Control
Chlorine resistant algae, that normally require the addition of algae control
chemicals, are eradicated as they pass through the UV system. The cost savings is
obvious when these chemicals are no longer needed, but more importantly, your
pool begins to approach a more “chemical free” state.
7. Lower Operating Costs
Your pool operating cost is greatly reduced through the installation of the TES UV
system. Using less electricity than a 60 watt bulb, the system is one of the lowest
operating cost method of achieving high water quality.
