“The reliability of the systems is a key fact behind the mandatory inclusion of UV systems for swimming facilities being considered by a number of states in the US”
minimise the risk of outbreaks and are now hoping more facilities in the UK will learn from Utah’s experience, and invest in ultraviolet protection. The Granta School in Cambridge, has chosen to replace its existing ozone system with an atg system for its on-campus special needs hydrotherapy rehabilitation facility as a way of improving water quality and enhancing disinfection. The school took the decision to replace the ozone system with UV technology due to the high capital running costs, several operational issues and required level of technical expertise associated with its complex operation. In comparison UV treatment is a simple, fully automatic process that cannot be overdosed, is lower in capital costs and performs the same oxidation AND disinfection tasks at a fraction of ozone’s running costs. The project was managed and installed by H20 Servicing Ltd (
www.h2oservicing.co.uk), specialists in swimming pool design, refurbishment, service and maintenance. H20 Servicing purchased and installed a state-of-the- art atg UV Inline ECL dual lamp system, which had been designed and manufactured in Wigan, Greater Manchester to client specifications such as bather load and pool size.
Site Manager Joanna Clarke said: “The UV system has had a tremendous impact on our water quality. We have had many issues relating to the complexity of our previous ozone system, including some safety concerns. What’s most impressive is how easy UV systems are to operate and their low running and maintenance costs.” Siemens Water Technologies believes ultraviolet disinfection is the perfect alternative to chemical addition systems and can be used as a bolt on multi-barrier approach to any disinfection process. The company’s Barrier M UV system provides an operator-friendly solution for low-and-medium flow rate disinfection applications, as well as a chloramines reduction solution for pool water treatment installations. The system consists of a
stainless steel reaction chamber with medium- pressure polychromatic lamps, and a remotely mounted microcontroller for control and monitoring capabilities. All models except M 35 include automatic quartz cleaning.
The system controls pathogens such as bacteria, viruses, and parasites, including cryptosporidium, which can be resistant to conventional chemical disinfection. In addition, the system provides a powerful disinfection solution without forming harmful disinfection by-products.
The Barrier M range is equipped with Wallace & Tiernan medium-pressure lamps. The wide emission spectrum of the lamps attacks the nucleic acid (DNA), cell wall, proteins and enzymes of waterborne pathogens. Such attacks not only inactivate the microorganism by preventing the replication of its DNA, but also destroy its repair mechanisms. The Barrier M reaction chamber is characterised by optimal hydraulics and low pressure loss, ensuring a high efficiency of the UV system. A recent success story for UV systems took place at the Student Recreation Centre at Texas A&M University which has four pools and three spas and was built in 1996. It has always been heavily used throughout the day with a total of 19,000 swimmers using the facilities every month. After 15 years, the university wanted to improve the air quality and upgrade its facility with leading-edge technology. The university already had a working relationship with Siemens as it came to upgrading its facility. The university worked with Siemens Building Technologies to install air conditioning and heating to make its facility more energy efficient. But it was the installation of the UV system which brought about real change. Siemens recommended that the Barrier M Series UV disinfection system would improve the air quality and water treatment.
The UV disinfection systems were also installed to provide a cost-effective, reliable, operator-

friendly chloramines reduction solution for pool water treatment installations. A typical problem for indoor pools is the so-called “pool smell” which is a synonym for a poorly performing water treatment system.
Barrier M systems will also improve the microbiological water quality because UV is also a very effective technology for the inactivation of bacteria and
viruses.The result of the new system was a transformation of air and water quality. “With the number of people that use the swimming facilities on a daily basis, we are very happy with the results we’re getting from the controllers and UV systems,” reported the university. spn
