What is one advantage of using chloramines instead of chlorine for disinfection?

Using chloramines for disinfection offers the significant advantage of producing fewer disinfection byproducts compared to chlorine. Disinfection byproducts, such as trihalomethanes (THMs) and haloacetic acids (HAAs), are formed when chlorine reacts with organic matter in the water. These byproducts can pose health risks and lead to regulatory challenges.

By utilizing chloramines, water treatment facilities can minimize the formation of these harmful byproducts. This reduction is particularly beneficial for drinking water systems aiming to comply with health regulations and maintain water quality. Additionally, chloramines possess a longer-lasting residual effect in the distribution system, which also contributes positively to maintaining overall water quality throughout the system.

While other options present different attributes of chloramines, they do not specifically highlight this critical advantage related to health and regulatory considerations in water treatment.
