<\/div><\/div><\/div><\/div><\/div><\/div>Application<\/strong><\/h2>\n25m Public swimming pool<\/strong>
\nA 25m public swimming pool was struggling to implement consistent reductions in chloramine (combined chlorine) levels \u2013 especially during peak swimming periods.<\/p>\nIn addition, enrolments at their Learn<\/em> to Swim<\/em> classes had failed to increase for the past 2 years due to parental concerns about allergic reactions to chloramines such as trichloramines.<\/p>\nThe Challenge<\/strong><\/h2>\nHigh chloramine levels<\/strong>
\nMaintaining water quality is challenging at public swimming pools because of the large numbers of people using the pool each day. Chlorine treatments are the most common way to control harmful pathogens and keep the water clean. The problem is, when free chlorine is mixed with perspiration, urine and oils (e.g. sunscreen and deodorant) chloramines are formed.<\/p>\nIt\u2019s the chloramines that cause the nasty \u201cchlorine\u201d smell in swimming pools. They are also responsible for sore eyes, skin irritations, asthma attacks and the rapid corrosion of swimming pool equipment.<\/p>\n
Public swimming pool operators are required to maintain low levels of combined chlorine due to the associated health risks for swimmers, in addition to regulations that need to be met.<\/p>\n
UV Requirements<\/strong><\/h2>\nFor this 25m public swimming pool, the UV treatment system needed to:<\/p>\n
\n- Decrease combined chlorine levels to less than 1ppm (parts per million)<\/li>\n
- Lower chlorine usage to improve swimmer comfort and reduce allergic reactions<\/li>\n
- Handle flow rates of 54m3<\/sup><\/li>\n
- Support easy installation into existing infrastructure<\/li>\n<\/ul>\n

UV-Guard\u2019s Solution<\/strong><\/h2>\nThe product specified: UVG X3-245<\/strong><\/p>\nThe UVG X3-245<\/a> system utilises three, 240W low pressure high output amalgam UV lamps to achieve a minimum UV dose of 60 mJ\/cm2<\/sup> at the required flow rate.<\/p>\nLow pressure UV lamps are not conventionally used for large scale swimming pool treatment. Instead, medium pressure UV systems have been the industry\u2019s preferred choice.<\/p>\n
While medium pressure UV disinfection systems have their place, research conducted in Australia and overseas is re-writing conventional thinking. There is growing evidence that low pressure UV disinfection systems are delivering similar results while providing greater energy efficiencies.<\/p>\n
Benefits of the low pressure UVG X3-245 over an equivalent medium pressure UV system:<\/p>\n
\n- Three times more efficiency \u2013 less power required to achieve an equal UV dose<\/li>\n
- Twice the lamp life \u2013 fewer replacements reduces disposal and maintenance costs<\/li>\n
- Less risk of overheating during intermittent flow \u2013 reduces the risk of premature lamp failure<\/li>\n<\/ul>\n
Due to the compact size and customised inlet and outlet connections, the UVG X3-245 was easily retrofitted into the existing plumbing infrastructure and plant room. UV intensity monitoring was provided and is displayed on the user friendly digital display. This allows the swimming pool operations staff to perform quick checks on the UV output, water quality and potential quartz tube fouling.<\/p>\n
The Results<\/strong><\/h2>\n![\"\"](\"https:\/\/uvguard.com\/uk\/wp-content\/uploads\/sites\/2\/2022\/06\/chlorine-levels-table.jpg\")
As with all public swimming pools, operators must complete daily on-site water quality testing to ensure the water consistently achieves a suitable standard. Below is a graph of two 7-day periods showing combined chlorine levels both before UV implementation and after.<\/p>\n
The UVG X3-245 consistently reduces combined chlorine levels to less than the required 1ppm, with average concentrations of less than 0.5ppm. Approx. 90% combined chlorine reduction has been recorded since the installation of the low pressure UV system, reducing the amount of chemicals in the water.<\/p>\n
Both pool users and the swimming pool operators have noticed a vast improvement in water and air quality.<\/p>\n
