Blog: Disinfection with UV light

There are usually many different germs in the air, in water and on surfaces. Some are harmless, while others can pose a serious health risk to humans.

Airborne microorganisms, such as viruses, bacteria, yeasts and moulds, are particularly prevalent in population dense areas such as airports, doctors' offices, hospitals and factories, - endangering the health of people and increasing waste by contamination of raw materials or food.

UV radiation reliably reduces germs and improves hygiene and storage conditions. To reduce the germ level in the long term, the germ-laden air can be disinfected at source in the supply air ducts. Short-wave UV radiation has a particularly strong bactericidal effect. It’s absorbed by the DNA of the microorganisms and destroys their structure, - inactivating the cells.

UV disinfection is used in a wide variety of applications and industries.

This is how UV lamps from Excelitas Noblelight are used for:

•  Drinking water, process water and ballast water treatment
•  Air disinfection and exhaust air purification
•  Sterilization of packaging materials and surfaces

Noblelight has been working with various institutes and research facilities for years. It has been scientifically proven that UV light renders germs harmless in an appropriate dose.

UV medium pressure, UV low pressure and also UV amalgam lamps are suitable for the disinfection of germs. Depending on the requirement criteria, the right lamp can be selected in consultation with a UV expert. Criteria can include:

• the time available to inactivate a germ
• energy consumption
• the required wavelength range
• acquisition costs
• size/compactness of the emitters

When choosing, however, care should be taken to ensure that the radiators do not generate ozone. The mechanism of action of ozone (via hydrocarbons) is completely irrelevant to germs.

Suitable lamps are:
