What is chloramine?
It is created by the reaction of chlorine when it acts as a disinfectant on the organic matter brought by the bathers (sweat, cream, saliva, urine).
“Inorganic chloramines, therefore without organic radicals, are derived from the reaction of chlorine (in the form of hypochlorous acid HOCl) with ammonia (NH3). Examples include monochloramine (NH2Cl), dichloramine (NHCl2) and trichloramine (NCl3). “
Why should we treat them?

- In order to avoid overflows caused by additional water supply.
- In addition, too many chloramines in the water can generate trichloramine in the air and can be a potential health hazard for bathers and employees. The management of trichloramine will also require additional air treatment and thus additional costs. Solutions are available for the measurement of trichloramine in air.
