What Is Chloramine and Why Is It Important?
Understanding Chloramine
Chloramine (NH₂Cl) is a powerful disinfectant formed by combining chlorine and ammonia in a controlled reaction. Unlike free chlorine, chloramine offers a longer residual time, stability, persistence, and reduced reactivity with organic matter. This makes it less corrosive, making it an ideal secondary disinfectant for public water systems and extensive building water networks.
How Chloramine Works
Chloramine, specifically Monochloramine is introduced into water systems to maintain a disinfectant residual throughout distribution networks. Its unique properties allow it to:
-
Penetrate biofilms: Effectively disrupt and prevent the formation of biofilms, which harbor pathogens like Legionella and Pseudomonas.
-
Maintain long-lasting residual: Stay active throughout the entire water system, including remote or low-flow areas (“dead legs”).
-
Reduce harmful byproducts: Produce fewer regulated disinfection byproducts such as trihalomethanes (THMs) and haloacetic acids (HAAs).
Chloramine vs. Free Chlorine
While free chlorine is an effective primary disinfectant, it dissipates quickly and reacts with organic matter to form potentially harmful byproducts. Chloramine, in contrast, offers:
-
Greater stability and persistence
-
Lower risk of taste and odor issues
-
Reduced corrosion of plumbing infrastructure
-
Superior control of waterborne pathogens over long distances

Why Choose Chloramine for Your Facility?
Superior Microbial Control
Chloramine’s stability and ability to penetrate biofilms make it highly effective against persistent waterborne pathogens, including:
-
Legionella pneumophila: The cause of Legionnaires’ disease, a serious and sometimes fatal pneumonia.
-
Pseudomonas aeruginosa: A common cause of hospital-acquired infections.
-
Other opportunistic pathogens: Including nontuberculous mycobacteria.
For more on the health risks of Legionella, visit the CDC’s Legionella resource page.
Lower Disinfection Byproducts (DBPs)
Regulatory agencies such as the EPA and World Health Organization have set strict limits on DBPs like THMs and HAAs due to their potential health risks. Monochloramine generates significantly fewer DBPs, helping your facility meet or exceed these standards.
Infrastructure Protection
Unlike free chlorine, which can be aggressive toward metal pipes and fixtures, monochloramine is less corrosive. This translates to:
-
Longer infrastructure lifespan
-
Reduced maintenance costs
-
Fewer leaks and failures
Consistent Residual and Coverage
Monochloramine’s persistent residual ensures that even the most remote sections of your water system receive effective disinfection, reducing the risk of microbial growth in low-flow or stagnant areas.
