LUMINOR UV Commercial/Industrial Application Education - Swimming Pools
The use of ultraviolet disinfection has been successfully used in the European markets for decades and is growing in popularity in the North American markets at a steady pace.
Swimming pool water must undergo treatment in order to remain clear and clean, free from harmful substances, bacteria, viruses, algae and other pathogens and suitable for use by swimmers. To accomplish this, traditional disinfectants such as chlorination have been used to control these microorganisms. Problems however due arise when using chlorine, specifically the formation of chloramines in the water caused by the reaction of free chlorine residuals with organic materials, such as bacteria brought into the environment by the users.
Issues of intense chlorine smell, eye, nose and throat irritation as well as red and itchy skin create a negative atmosphere for the pool's managers and an unpleasant swimming experience for the users. Additionally, these chloramines, and their related forms, can also cause corrosive condensation, which leads to the damage of pool buildings
UV is an excellent choice to supplement the pools existing disinfection system as the use of UV will greatly reduce the quantity of chlorine used in the pool, without the creation of any potentially harmful disinfection by-products (such as chloramines). Additionally, UV is extremely effective at eradicating Cryptosporidium in the water while also addressing the bacteria, viruses, algae and other pathogens that may exist. As an added benefit, a properly designed UV system can also address any of the chloramines or chlorinated organic compounds issues caused by the chlorine. The use of UV as a disinfectant also has the benefit for bathers that are especially sensitive to traditional swimming pool disinfectants or have allergies to chlorine.
Although not intended to act as a stand-alone disinfectant for swimming pools, the use of UV has significant benefits that many swimming pool operators have long since known about. Operational costs are reduced, both water and air quality inside of buildings is increased and the requirement for backwashing, dilution and shock treatments is greatly reduced. Couple this with satisfied swimmers and one can easily see how UV and pools is a winning combination!
