atg’s ECF UV disinfection system
Ultraviolet (UV) systems have never had a higher profile. More used by pool operators than ever before as they try and improve the swimming experience, this autumn sees the arrival of new products on the market; more focus on low pressure units for domestic pools plus claims that UV’s ability in killing off chloramines is being recorded at almost the 100% mark
WHY HAVE UV SYSTEMS BECOME SUCH A POPULAR OPTION?
• They are very effective against chloramine reduction – scoring as high as 99.9% success
• Their presence significantly improves the environmental air quality of the swimming pool
• They offer long term reduction in water and energy costs
• They are simple to install • Swimmers often report on better water quality when they use a UV pool
• The longer lamp life and low lamp replacement gives improved investment paybacks
Swimming pool cleansing systems have tended to come and go but now there’s a clear long term trend toward UV.

UV is not the cheapest system and there’s still, manufacturers claim, confusion about the link between UV and the use of chlorine. In fact chlorine is still required for residual disinfection, but pools using a UV system require up to 90% less chlorine than pools without UV.
But that aside, UV is now a worldwide phenomenon giving what independent experts believe to be the best results and the best financial return in the search for safe clean swimming water.
Ultraviolet systems now lead the race to

provide bacteria free water and more pleasant swimming conditions.
This autumn sees the introduction of new low pressure UV systems which will come within the range of smaller pools. Such lower pressure systems may not completely eradicate chlorine smells but their effectiveness in killing bacteria will still be very efficient.
UV treatment is known to break down chloramines, resulting in a more pleasant and inviting environment, reducing ‘red eye’, skin irritations and the chlorine smell associated with indoor swimming facilities. The elimination of chloramines also produces clear, sparkling water, and vastly reduces the need for chemical shock treatments and backwashes.
The systems are compact and can usually be installed within existing pipe work. The only regular maintenance is an annual service at which the lamp is changed.
