UV SYSTEMS
Ultraviolet And Ultra Effective
When it comes to the effective treatment of water in pools and other wet leisure environments, UV Systems are now an established choice, particularly in \ commercial settings. Their success is no real surprise when you consider UV’s many benefits, but their big selling point is a large reduction in the use of chlorine as a sanitiser. As more pools make the switch to UV, there’s plenty of product choices to consider we take a look at the options By Jon Wadeson

ltraviolet light, or UV light as it’s most commonly shortened to, is an extremely effective disinfectant – and why wouldn’t it be, it’s effectively a form of radiation – but so too is the light from the sun, so it’s not time to panic just yet! UV’s power lay in its ability to inactivate bacteria, viruses and other pathogens that can exist in various wet leisure settings, including the Cryptosporidium and Giardia variants which are able to survive in water despite the presence of a variety of sanitisers (and that includes our reliable friend chlorine). In addition to its biocide action, UV has a powerful oxidising effect which successfully removes organic pollution from swimming pool and spa water, so when UV is used in conjunction with chlorine, the chloramines that cause eye and skin irritation are turned into easily removed by-products. Although effective, UV is still a secondary disinfection process that is used alongside, treatments such as chlorine as the principal disinfectant in pools and spas. The reason for this is that UV only treats water as it passes through the lamp, therefore a sanitiser such as chlorine is needed to provide a constant defence throughout the rest of the water system. Through the use of UV, it is possible to drastically reduce sanitiser levels by as much as 80% and down to as little as 0.5ppm. In addition to requiring less chemicals, water treated with a UV system will also require less backwashing and heating costs will be improved too – and that could be an extremely important factor now energy costs are spiralling! So in summary, the water within a UV treated pool or spa uses less chemicals, requires less backwashing and both water and heating costs are reduced, however chlorine use, whilst minimised, still plays an essential role in providing the safest possible water. With numerous benefits, it’s no wonder that UV has become a popular choice and

there are plenty of options available to choose from for both commercial, and increasing residential sectors too. In this latest issue, we shine a light on just some of the ultra effective options that are making water safer through the power of UV.
MAKE LIGHT WORK OF WATER DISINFECTION WITH BIO-UV If a more natural disinfection system sounds appealing for your commercial or domestic pool, Golden Coast offers a range of UV water treatment systems. Adam Clark, Sales Director at Golden Coast explained: “Though effective, chemicalbased water disinfection systems such as chlorine can cause skin and eye irritation due to by-products remaining in the air, UV creates a much more pleasant pool environment for swimmers, allowing for a reduced reliance on chemical processes while still ensuring the water is safe and clean. “Instead of adding anything to the water, UV systems treat the water directly during filtration. In Easy to install and maintain, the BIO-UV from Golden Coast features five models to suit different pool sizes
this stage, the cell DNA of microorganisms such as viruses, algae and bacteria is broken down by state-of-the-art UV-C lamps emitting a specific wavelength of light at a high intensity.” BIO-UV is one such system available from Golden Coast. Easy to install and maintain, and the range features five models to suit different pool sizes, each designed for long service with lamps lasting up to 13,000 hours. The BIO-UV Delta UV system is constructed from E series-special 8” PVC plastic material for use in both indoor and outdoor environments, and includes a high output, low pressure UV lamp. BIO-UV MP (medium pressure) is an ideal solution for commercial pool setups. The system can reduce combined chlorine levels by up to 80% for an average level of 0.1 to 0.3 ppm, and is capable of destroying monochloramine, dichloramine and trichloramine. Units are available with either a digital screen or touch screen for displaying different reactor parameters to enable more efficient management and maintenance.
