UV Disinfection

Bacteria and viruses (germs) travel through the air, causing and worsening diseases. When someone sneezes, coughs or speaks, tiny mucous droplets or aerosols filled with viruses or bacteria scatter in the air or end up in the hands where they spread on surfaces like doorknobs. Inhaling these viruses or bacteria can spread coughs, colds, influenza, tuberculosis and coronavirus. This is especially concerning in enclosed indoor areas where large groups of people gather for extended period.

Germicidal ultraviolet (GUV) is proven and has been used for decades in the disinfection of air, water and surfaces. Not all ultraviolet are GUV however, only UV-C is shown to be effective in killing germs (UV-C is short-wavelength ultraviolet from 200 to 280 nanometers).

 

Effective and safe disinfection

BSL partners with the industry leader Purion to provide effective and safe disinfection of air, surface and water. Its effectiveness and safety are tested and certified by established laboratories. Purion advanced UV products are made in Germany in accordance with the highest standards and regulations.

Air Disinfection​

Air disinfection kills off airborne microorganisms such as viruses, bacteria, yeasts and fungi, countering diseases that are spread through air. Since no chemicals are used, it is a reliable and environmentally friendly method.

What is Ultraviolet (UV) Disinfection?

UV belongs to the category of electro-magnetic radiations. Other types in the category include X-ray, light, radio and television radiation. The difference between these electro-magnetic radiations is the length of the radio waves. The shortest wavelengths belong to the cosmic radiation. Very long wavelengths are associated with alternating current. Optic radiation is a subset of electro-magnetic radiations. UV, Visible Light and infrared radiations are all part of optic radiation.

Ultraviolet is that part of electro-magnetic radiation bounded by the lower wavelength extreme of the visible spectrum and the upper end of the X-ray radiation band. The spectral range of ultraviolet radiation is, between 100nm and 400 nm (1nm=10-9m) and is invisible to human eyes.

Using the CIE classification the UV spectrum is subdivided into three bands:

UVA (long wave radiation) from 315 nm to 400 nm

UVB (medium wave radiation) from 280 nm to 315 nm

UVC (short wave radiation) from 100 nm to 280 nm

A strong germicidal effect is provided by the radiation in the short wave UVC band. The UV radiation emitted by a source is expressed in watts (W) and the irradiation density is expressed in watts per square metre (W/m²). For germicidal action dose is important. The dose is the irradiation density multiplied by the time (t) in seconds and expressed in joules per square metre (J/m²). 1 joule is 1 watt-second.

Microorganisms effective resistance to UV radiation varies considerably.
