Ultraviolet disinfection is an extremely cost efficient means of killing micro-organisms, which can range from bacteria and viruses to algae and protozoa, within a contained environment. UV disinfection is used in air and water purification, sewage treatment, protection of food and beverages and many other disinfection and sterilization applications.

A major advantage of UV treatment is that it is capable of disinfecting water faster than chlorine without the need for large treatment tanks and use of harmful chemicals.
