The most common method now used for disinfecting pools is chlorination. It is an inexpensive and efficient system but, unfortunately, there are often some problems associated with it, such as the unpleasant smell, the decline in the quality of air, and the irritation bathers experience to their airways, skin and eyes.

In fact, a number of studies have shown that the prolonged exposure to chlorinated products – a common phenomenon among people who play water sports such as swimming and water polo – is linked to the development of bronchial swelling and hyperresponsiveness.

To overcome this problem, the Fluidra group has developed Freepool, a system for treating public pools based on neolysis technology, which combines salt chlorination and UV radiation, as well as correcting pH levels by using carbon dioxide (CO2).

A widespread complaint of pool maintenance staff is the lack of reliable information about alternatives to chlorine. In the case of Freepool, research teams from Hospital Clínic de Barcelona and Universitat Autònoma de Barcelona have conducted two studies that compare the effects that chlorine and CO2 have on bathers’ organisms and on pool environments in general.

The studies concluded that carbon dioxide reduces water’s conductivity and, as a consequence, prevent the formation of salts and other solutes that are detrimental to the well-being of pool users. Freepool prevents lesions to the respiratory tracts, reduces symptoms experienced in the eyes, nose and skin, eliminates the smell of chlorine and improves environmental quality with a 75% reduction of oxidants in the air.

In addition, with Freepool there is no need to renew pool water, which reduces the number of products required to treat it and results in major power and money savings.
