Water Parks

As water features, wave machines, flumes and splash pads raise the fun factor in swimming pools, traditional methods of disinfecting water, using chlorine, are causing problems for operators and customers alike. Higher water temperatures and increased turbulence in leisure pools requires increased dosages of chlorine, leading to pool users complaining of burning eyes, red or itchy skin and an over powering chlorine smell throughout the facility. In some extreme cases the fabric of the building has also been attacked through corrosive condensation.

The main reason for these problems is the production of chloramines in the water caused by the reaction of free chlorine residuals with organic materials, such as bacteria brought in to the environment by pool users. Whilst Ozone can be successful at reducing chloramine levels, both the installation and operation is extremely expensive and requires skilled personnel to operate the plant, again driving up operating costs.

The swimming pool industry has therefore sought alternative ways of disinfecting water and reducing the organic loading of water. Ultraviolet treatment provides the perfect answer. UV wavelengths between 240 and 280 nanometres deactivate all micro-organisms, particularly Pseudomonas (SP) and Ecoli. Manufacturers such as atg UV can incorporate UV systems into existing control strategies to protect against micro-organisms, including Chlorine resistant pathogens, such as cryptosporidium

Additionally, a correctly sized UV treatment system reduces chloramines, the compound responsible for skin irritations, red eye and the often overpowering chlorine smell. The result is safe, glacier clear sparkling water, fresh air and happy customers. Operators worldwide have reported a significant drop in combined chlorine levels, chlorine smell and a large reduction in the need for taxing back washing and shock treatments following a UV installation.
