Our UV swimming pool water treatment systems are proven to significantly improve swimming pool water quality by breaking down problem chloramines – the cause of eye and skin irritations – and protect against harmful chlorine-resistant microorganisms such as Cryptosporidium.
For operators wanting bright sparkling water, fresh clean air and residual chlorine levels as low as 0.5ppm, UV technology has become the treatment of choice worldwide for swimming pools, spas and water parks.View Gallery
The problem: Chloramines are the unpleasant chemical compounds which are formed when free chlorine reacts with nitrogenous compounds such as uric acid, urea, ammonia, histidine, and creatine introduced to the pool environment by bathers.
As the cause of itchy skin, eye irritations (red eye), headaches and unpleasant chemical odours, chloramines pose a significant problem for both leisure operators and bathers, with independent research linking chloramines as a cause of asthma in regular swimmers, lifeguards, and instructors.
Additionally, chloramines also damage the structure of aquatic facilities through corrosive condensation, degrading structural steel, roof supports, furniture, poolside equipment and ventilation ducts.
How does UV provide a solution: The polychromatic wavelengths of medium pressure UV systems break the bonds within all three of the chloramine molecules (low-pressure UV is effective only on mono-chloramine):
The results of breaking down and removing the chloramines from the swimming pool environment is crystal clear water, fresh clean air and a significant reduction in skin and eye irritations. In addition, the requirement for ‘shock dosing’, and the use of additional chlorine is significantly reduced, and in most cases, combined chlorine levels are reduced to as little as 0.2 ppm.
Using ultraviolet light for swimming pools is a proven and effective barrier for Cryptosporidium and other emerging chlorine-resistant microorganisms, such as Giardia. It’s important to understand the hidden dangers of Cryptosporidium.
Used extensively in drinking water for over 100 years, many leisure operators are now installing UV systems as standard to ensure their water does not pose a risk to public health and safety.
Due to a thick outer membrane, it takes more than 10 days to destroy Cryptosporidium in a normal pool using traditional chemical methods (25 OC with free chlorine levels of 1 ppm).
Considered the best protection technology available, UV systems are independently proven as an effective barrier to safeguard against Cryptosporidium, Giardia and 15 other chlorine resistant waterborne microorganisms that pose serious risks to bather’s health and safety.
Whilst all UV systems will provide some level of protection against Cryptosporidium, it is important to note that only UV systems that have undergone independent 3rd party validation testing, using bio essay testing with live surrogate microorganisms can be guaranteed and trusted to deliver the required 3-log reduction (99.9%) reduction of Cryptosporidium in a single pass through the UV System that is needed in order to protect public health and keep swimmers safe from infection.

In order to prevent the manipulation of UV disinfection performance by manufacturers regarding by UV Technology, the delivered UV dose and capacity of their equipment, the requirement for independent 3rd party validated performance is now a fundamental requirement.
Using the test protocols developed by the USEPA Ultraviolet Disinfection Guidance Manual, atg UV Technology systems are rigorously biometrically tested using live surrogate microorganisms (MS2) for guaranteed disinfection performance against Cryptosporidium and other microorganisms.
We have more 3rd party validated, NSF-50 certified and Model Aquatic Health Code (MAHC) compliant medium pressure UV systems than any other UV manufacturer. All systems are guaranteed to provide a minimum 3-log reduction (99.9% kill) of Cryptosporidium.
