or maximum level for ozone in swimming pool water because of the multiple variables
involved such as air temperature, water temperature, humidity and bather load. Pool
owners who have been using chlorine of bromine for a few season know how much sanitizer
they use in a season or year. Installing an ozone generator in these pools has resulted in
a significant reduction in the amount of chemical sanitizer used. The longer the ozone
operates each day, the greater the reduction in chemical sanitizers. Pool owners have
had reductions in sanitizer use of 50-90%. Your savings may vary based on pool usage
factors. Ozone is not sold on the basis of being less expensive than other sanitizers such
as chlorine and bromine are. Its value is in smoothness and sparkles to the pool water,
elimination of the dry, itchy skin that chemicals can produce burning red eyes and bleached
bathing suits. Other important advantages include reduced pool maintenance and reduced
exposure to toxic chemicals in storing, handling and swimming.
Will my ozone generator help the ozone layer?
Ozone from a swimming pool ozone system will not add anything to the atmosphere or the
ozone layer. When injected into the water properly, no ozone escapes into the atmosphere.
Even if it does get into our atmosphere, it is like a drop in the ocean. Also, the ozone would
have to be transported 9 to 18 miles up. The ozone results almost entirely from oxygen
(O2) splitting apart into two atoms of oxygen (O2) by solar ultraviolet radiation (the sun’s
UV rays) and then combining with molecular oxygen (O2) to form ozone (O3). Atmospheric
ozone plays a critical role for the Earth by absorbing the ultraviolet radiation from the sun
with a wavelength of between 240 and 320 nanometers (nm), which would otherwise be
transmitted to the Earth’s surface. This radiation is responsible for sunburn to human
skin. In addition, the incidence of skin cancer has been statistically correlated with UV light
intensities of 290 to 320 nm.
