What is ultraviolet disinfection and how does it work?
Ultraviolet light treatment uses ultraviolet light to disinfect water or reduce the amount of heterotrophic (non-harmful) bacteria. This method uses no chemicals, and produces no taste or odour. It takes only a few seconds of exposure to disinfect the water, is easy to install and relatively inexpensive. However, it is effective in ensuring only the microbiological safety of the water, and further treatment is needed to remove any parasites and other contaminants. The device is installed so that water passes around the UV light which is illuminated only when the water is flowing through the system. A high intensity light disinfects the water as it passes around the light source. If the water is not clear, the turbidity or dissolved solids in the water may form on the surface of the UV light source, slowly diminishing the effectiveness of the process. Again, modern devices have a fail safe, shut off switch which prevents water from flowing through a non-functioning device. The advantage
