Ultraviolet disinfection systems for the swimming pools industry - Water and Wastewater - Swimming Pools

Ultraviolet disinfection is now an established method of water treatment for Swimming Pools, Spas, Hydro Pools, Splash Pads and Water Features, and has become the preferred treatment choice for a number of leading international leisure brands. atg UV`s range of treatment systems are proven to improve the swimming pool environment by improving water quality, air quality and safety, leading to increased customer satisfaction. UV systems not only provide disinfection against the 17 known chlorine resistant micro-organisms, such as Cryptosporidium and Giardia, which have a thick outer membrane making them highly resistant to traditional Chlorine disinfection, UV also destroys chloramines. Chloramines are formed when free chlorine reacts with organics, such as sweat, body fats and urine, brought into the pool environment by bathers.

Trichloramines in particular are powerful irritants, which are responsible for burning red eyes, itchy skin, respiratory complaints and the often over powering chlorine smell associated with indoor pools. Additionally, chloramines are also the cause of corrosive condensation, which leads to the dangerous damage of pool buildings and structures, such as ventilation ducts.

Significant cost savings
The cost of pool water is ever increasing, taking into account water costs, heating, chemicals and actual discharge costs. As UV systems can significantly cut chlorine usage, the requirement for backwashing, dilution and shock treatments is greatly reduced. Even pools with outdated dosing and filtration equipment can reduce their operational costs by implementing a correctly sized UV treatment system.

UV Systems for Swimming Pools
As UV systems become more popular for swimming pool applications, atg UV Technology now offer a number of UV systems with pre selected options tailored to the specific requirements of swimming pool operators. Typical swimming pool UV units should include: 316L stainless steel chambers, UV monitoring, automatic wiper systems, strainer baskets and the option for half to full power for energy savings during periods of no/low use.

Additionally, UV manufactures should always follow best practise when sizing a UV system, ensuring to supply UV equipment capable of providing a 60 mj/cm2 dose (average) at a transmission of 94% and taking pool usage into account e.g. typical bather load, additional disinfection technologies, such as filtration and pool volume turnover.
