For disinfection, chlorine is obligatory in public outdoor pools. When chlorine reacts with sweat, urine, fats or other components, it produces disinfection by-products, such as chloramines (combined chlorine).
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.

Ultraviolet (UV) light is simple and proven technique for removing chloramines and, most importantly, trichloramine (TCA). UV light contains the energy (wavelengths) to break down chloramines via photolysis. Breaking down TCAs requires short wavelengths below 240 nm emitted by medium-pressure (MP) UV lamps.
Safe and sparkling pool water is the result of using Welgo systems in outdoor pool water.
