What are chloramines?

Chloramines are specifically formed when ammonia reacts with chlorine in water, resulting in a group of chemical compounds that include monochloramine, dichloramine, and trichloramine. This process can occur when chlorine is added to water that contains ammonia, whether introduced intentionally or as a natural part of the water source.

The use of chloramines as a disinfectant is beneficial because they provide a longer-lasting residual effect in the distribution system compared to free chlorine. This makes them particularly useful in maintaining water quality as the water moves through pipelines. Additionally, chloramines are less reactive with organic materials than chlorine, leading to the formation of fewer byproducts that could potentially lead to health risks. Hence, understanding chloramines and how they form is crucial for water treatment processes and ensuring safe drinking water.
