What are chloramines?

Chloramines are chemical compounds that form in pools and spas when chlorine reacts with organic matter such as sweat, oils, and urine. These compounds are also known as combined chlorine and give off an unpleasant odor and can cause skin and eye irritation to swimmers. Unlike free chlorine, which is effective in killing bacteria, viruses, and other harmful pathogens, chloramines are not effective and can actually reduce the effectiveness of chlorine as a sanitizer.

There are three types of chloramines: monochloramine, dichloramine, and trichloramine. Monochloramine is the most common form of chloramine in swimming pools and is formed when chlorine reacts with nitrogen-containing compounds. Dichloramine and trichloramine are formed when chlorine reacts with organic matter and ammonia compounds in the water.

Chloramines can be detected through a strong, chlorine-like odor in the water, and they can also cause eye irritation and respiratory problems for swimmers. In addition to their unpleasant effects on swimmers, chloramines can also cause damage to pool surfaces, plumbing, and equipment, so it’s important to prevent their formation and reduce their levels in pool water.

The chemistry behind chloramines in pools

Chloramines are formed when chlorine reacts with ammonia and nitrogen-containing compounds from swimmer’s sweat, urine, and other bodily fluids. Chloramines are the byproducts of the disinfection process and are known as combined chlorine.

The presence of chloramines in the pool can be a problem as they produce a strong, unpleasant odor, irritate eyes, and cause respiratory problems. Chloramines can also reduce the effectiveness of chlorine in killing harmful microorganisms.

When the level of chloramines in the pool exceeds a certain threshold, it is necessary to shock the pool with high levels of chlorine to break down the chloramines and restore water quality. Regular monitoring of chloramine levels is essential to prevent their buildup and maintain a healthy swimming environment.

Sources of chloramines in pools

Chloramines are a byproduct of the chemical reaction between chlorine and organic substances in the water. Sweat, urine, and other bodily fluids, as well as cosmetics and lotions, can contribute to the formation of chloramines. In addition, some types of algae can release compounds that react with chlorine to form chloramines.

Another common source of chloramines is the introduction of contaminated water into the pool. This can occur when filling the pool with water from a source that has not been properly treated with chlorine or when adding water to the pool that has been used to clean pool equipment or accessories.

Finally, poor maintenance practices can also contribute to the buildup of chloramines. For example, not regularly testing and adjusting the chlorine levels or not properly cleaning pool filters can lead to the accumulation of organic matter in the water, which can then react with chlorine to form chloramines.
