What is the combination of chloramine?

Chloramines, also known as combined chlorine, are formed when free chlorine reacts with ammonia like compounds called amines. “Free Chlorine” is measured by the use of DPD#1 tablets .

How do you make chloramine?

In dilute aqueous solution, chloramine is prepared by the reaction of ammonia with sodium hypochlorite: NH3 + NaOCl → NH2Cl + NaOH. ), which do not react further. The chloramine solution can be concentrated by vacuum distillation and by passing the vapor through potassium carbonate which absorbs the water.

How is chloramine measured?

An FAS-DPD test kit is the most accurate way to measure chloramines, using a titration method. When the level of chloramines is 0.3 ppm or higher, the standard practice is to effectively shock the pool to a a high enough level of free chlorine, 10-20x the amount of chloramines – to break apart the chloramine bonds.

What is chloramine in pool water?

Chloramines are a type of combined chlorine that form in water and then off gas into the air above the water. Using air handling 1,2 systems to limit the amount of fresh air brought into the swimming area and limit the amount of air polluted with chloramines exhausted out of the swimming area.
