What is monochloramine commonly identified as?

• A. Free chlorine
• B. Chemical used to dechlorinate water
• C. Combined chlorine
• D. Chemical used to minimize corrosion

Answer: (C)

Monochloramine is commonly identified as combined chlorine because it is a chemical compound formed when ammonia reacts with chlorine. This process results in the formation of chloramines, which are used in water treatment as a disinfectant. Monochloramine is specifically one of the types of chloramines, along with dichloramine and trichloramine. It is often preferred in water distribution systems because it provides longevity in residual disinfection compared to free chlorine and has less potential to form harmful byproducts. In the context of water treatment, combined chlorine refers to chlorine that has reacted with substances in water, such as ammonia and organic matter, as opposed to free chlorine, which is the chlorine that remains unreacted. The distinction is key in water quality management and disinfection processes.
