In terms of water treatment, what are dissolved gases like Ammonia and Hydrogen Sulfide associated with?

Dissolved gases such as Ammonia and Hydrogen Sulfide are primarily associated with chlorination during the water treatment process. Chlorination is a critical step used to disinfect water, where chlorine is introduced to reduce or eliminate harmful microorganisms. When chlorine interacts with ammonia present in the water, it forms chloramines, which are less effective disinfectants compared to free chlorine but can persist in the water for a longer duration.

Furthermore, both Ammonia and Hydrogen Sulfide can contribute to odors and taste issues in water supplies. Chlorination helps in controlling these odors and improving overall water quality. While other treatment processes like biodegradation, coagulation, and filtration may play important roles in overall water treatment, they are not as directly related to the handling of these specific dissolved gases as chlorination is. Understanding the interaction of these gases during chlorination informs water operators on how to best manage and treat water efficiently.
