UV-C lamp – hot tub disinfection with ultraviolet light
A device that disinfects water using short-wave ultraviolet light, able to destroy viruses, bacteria and also algae. It is not used on its own; a reduced dose of a disinfectant, e.g. chlorine or hydrogen peroxide, is always also added to the water. It can destroy combined chlorine, just like an ozonator. It is a better option for assisting water disinfection than an ozonator. The effectiveness of a UV-C lamp tube gradually decreases; after roughly two years the tube needs to be replaced even if it still lights up. Modern pool-water treatment plants can no longer do without a UV-C lamp and they are installed in all facilities where there is greater contamination of the water.
