Ultraviolet light is the sun’s way of controlling airborne microorganisms
The Earth’s ozone layer allows just enough UV light from the sun through the atmosphere to keep the air from being overly contaminated with bacteria and viruses. Since realizing this, people have harnessed the power of UV light to control biogrowth anywhere it is harmful. UV is used widely in the medical, pharmaceutical as well as the food and beverage industries to sterilize instruments, equipment, and especially water.
Ultraviolet (UV) light occurs just below visible light in the electromagnetic spectrum, is a component of sunlight, and is categorized into three sections, A, B and C. The “C” band of ultraviolet light (UV-C) is a natural disinfectant. Its use for sterilization is a proven technology, and has been used to control microorganisms since the 1930’s in medical and pharmaceutical applications, in the food and beverage industries, and in water treatment in homes, businesses and industry.
