What Is Chloramine?

Chloramine is a mixture of chlorine and ammonia, which is added to the water of many cities as a substitute for free chlorine. It is often referred to in the plural, as chloramines, because it can take on a number of forms according to the pH and mineral content of the water. Read more about Chloramines

What Type of Water Filter Removes Chloramines?

The use of monochloramine as a primary disinfectant in a municipal water supply presents specific removal issues due to its low degradation rate. This means that the disinfectant will be persistent and have a long life within a municipal water supply. This has prompted KDF Fluid Treatment, Inc., to investigate the use of its products as a reductant for monochloramine in potable water.

There is a relationship between pH and the various oxidation states of nitrogen compounds. Decreasing the bulk pH of the solution increases the acidity in the vicinity of the mediums surface that can then facilitate monochloramine reduction. The presence of a metal ion that can be precipitated as a hydroxide can have this effect. This is the basis of the KD 85 mechanism by which KDF Process Media reduces monochloramine.

CuZn uses a KDF85 water filter, which breaks the bond between chlorine and ammonia that is used to make chloramines. Once the chloramines are reduced to chlorine and ammonia, they are easily removed.
