ADVANTAGES OF UV OVER CHLORINE
The use of chlorine, in one form or another, has been the common method of
swimming pool water disinfection for many years. While not perfect, it has done a
reasonable job however various shortcomings of chlorine use have been, for the
most part, accepted as normal by the pool owning public.
We all know that water, if left untreated, will stagnate and a variety of micro-
organisms will flourish and cause health hazards. The same holds true if water is
not properly treated or under dosed with a sanitising agent. Therefore, in our pools,
we all strive for the best environment possible.
Are private pool owners successful in maintaining good quality pool water?
In general the answer has to be “no”, however our UV systems offer excellent
disinfection and protection. When one sees algae in pool water that is not clear and
sparkling, etched or green plaster, or the smell of chlorine is present in the pool, it
is easy to see that manual addition of chlorine is not necessarily the solution to a
safe pool water environment.
Automatic feeders, which constantly add small doses of chemical are not the
solution since fluctuations in bather loading, temperature changes, sunshine
(which dissipates chlorine) etc. are not taken into consideration.
So how does one ensure the health of those using the pool, without having specific
knowledge of chemistry or constantly tending to the pool water?
The answer is “Ultraviolet (UV) Sanitation”. This is the same technology used
worldwide in public swimming pools which see far higher bathing loads than the
typical residential pool. The TES range of UV units now make this technology
available at affordable prices for residential pools.
The units are easy to install, indoors or outdoors, and require only periodic thimble
cleaning and a once per year lamp replacement.
What are the advantages of using UV for pool sanitation over chlorine.
1. Consistent Sanitation Level
The TES UV system is ON and doing its job whenever the pool circulation is
operating. Thus, 100% of the pool water entering the UV reactor is sanitised before
returning to the pool
By contrast, chlorine is dosed into the pool at various times, for example, once or
twice a week. Thus, the pool is charged (when the chlorine is added) with a large
dose of chemical which then dissipates until the next dose. As a result, there is no
consistent level of chlorine. This can cause severe problems when the chemical
level in the pool is either too high or too low.
