Swimming in pool water should be a healthy and pleasant exercise. A clear, safe, sparkling swimming pool with no unpleasant smell is the right of every swimmer and the objective of every pool manager.

The physical, chemical and microbiological states are constantly changing in a busy swimming pool. Swimmers, sweat, urine, pool toys and other factors introduce pollution almost continuously into indoor pool water.

Vigilant filtration, dosing and disinfecting are necessary to maintain a water quality that is ideal in indoor pools.

For disinfection, chlorine is obligatory in public pools. When chlorine reacts with sweat, urine, fats or other components, it produces chloramines (combined chlorine). These chloramines produce the typical “chlorine smell” and “red eyes”.

The most important component causing this effect is trichloramine (TCA), nitrogen trichloride. Trichloramine is the most irritating of all chloramines. Scientific reports indicate that trichloramine may cause childhood asthma and allergic diseases. In pool water treatment, reducing TCA is a critical goal.

Besides the effects of TCA on humans, their highly corrosive properties can also be harmful to the structure of the pool building.

Ultraviolet (UV) light is simple and proven technique to remove chloramines, and most importantly trichloramine (TCA). UV light contains the energy (wavelengths) to break down chloramines. Short wavelengths below 240nm can break down TCA. For mono- and dichloramines resp. 245 and 300 nm are effective.

The broad spectrum of bestUV’s medium-pressure (MP) UV lamps contains all the wavelengths needed to break down all chloramines found in pool water.

A bestUV system can ensure a more pleasant and healthy environment and less corrosion in the pool building.
