What is formed during the second part of chlorination?

During the second part of chlorination, chlorinated byproducts such as chlororganics and chloramines are indeed formed. This process occurs after the initial reaction of chlorine with organic materials and ammonia present in the water.

In chlorination, the first phase primarily involves the reaction of chlorine with water to form hypochlorous acid, along with various free chlorine species. However, as the chlorination process progresses, especially when chlorine reacts with ammonia or organic compounds, chloramines and chlorinated organic compounds emerge as significant byproducts.

Chloramines are formed when chlorine combines with ammonia and can vary based on the concentration of chlorine and the conditions of the water being treated. Additionally, chlorinated organic compounds, or chlororganics, can arise from the reaction of chlorine with organic matter in the water.

Thus, the formation of chlororganics and chloramines during this phase of chlorination highlights the complexity of the chlorination process, elucidating the potential impacts on water quality and the need for careful monitoring and management of these byproducts in water treatment systems.
