Prevent RWIs in Pools & Spraygrounds

Keeping swimmers safe is one of the most important jobs you have in running your aquatic facility. But depending on the type of sanitization system you use, people using your pools and splash play areas could be at risk from recreational water illnesses. Some infectious agents, such as cryptosporidium and giardia have developed resistance to chlorine. But there are measures you can take to prevent people from getting sick at your pool. And they serve an added bonus of eliminating chloramines, which can cause problems for patrons and your facility alike.

Q: What can we do to protect our swimmers from RWIs?

A: The adoption of UV light technology to help disinfect your pool's water can help protect patrons from pathogens. While it shouldn't be seen as a complete replacement for chlorine—and it's certainly no reason to ignore poor pool hygiene practices—a UV system can provide primary disinfection of waterborne pathogens. What's more, UV systems can reduce the amount of chlorine you'll need to keep your pool's water clean and clear.

It works much the same way as strong sunlight to permanently purify your pool's water by inactivating the biological impurities. Powerful lamps designed specifically for use in pools will produce concentrated ultraviolet radiation, which destroys the microorganisms.

Q: Why should we be concerned about chloramines?

A: Combined chlorine, or chloramines, is created when chlorine combines with organic compounds introduced into your pool, such as urine, sweat, hair, suntan oil and more. These compounds react with chlorine to form chloramines, which produce the unpleasant odor some people associate with swimming pools. These chemicals can cause red eyes and skin irritation, and have negative effects on people's health, including an increased risk of asthma. They also have a negative impact on the steel structure of pool buildings, and can cause the water to become cloudy—a dangerous situation.

While air treatment systems can help reduce chloramines, it's better to eliminate them before they are formed. UV systems effectively remove them from the pool entirely.
