UV disinfection how does it works?

r2d2 UV disinfection

Since 1877, scientists know the microorganisms can be eliminated by UV rays. Nearly 50 years later, however, they discovered the specific type of frequency that was the most damaging.

In the 1950s, researchers knew that UV rays penetrate cells and damage the nucleic acids or deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). This led to the commercial development of multiple UV disinfection devices, primarily with mercury vapor, which produces UV having the most effective frequency for the destruction of microorganisms. Today, UV disinfection devices use xenon UV rays.

UV disinfection is used in many hospitals

UV disinfection devices are used in hospitals such the ones in Vancouver and Hamilton. It is the natural evolution of the UV disinfection, to which are added the cleaning and disinfecting surface and a good dose of prevention.

Combined with touchless systems for bathrooms and public spaces, hospitals are able to reduce the number of surfaces to be disinfected to prevent nosocomial infections.

In any case, these robots do not replace the housekeeping staff but add a small sector futuristic air … don’t you see a family resemblance with this R2-D2 designed by Agent-Spiff?

A Brief History of Bleach

Bleach has been studied for the first time by a French chemist named Claude Louis Berthollet in 1775. His factory was based in Paris in the district of… Javel! That is why the French are calling it: Eau de Javel (Javel Water).

At first, bleach was used for laundry and as a fade. From 1820, a pharmacist named Antoine Germain Labarraque studied more deeply its disinfecting properties . In the XIX Century, it was commonly used as a disinfectant and water treatment. The NASA used bleach during the Apollo program to disinfect the Apollo XI rocket after its return, in order to avoid contaminating Earth with potential dangerous viruses!

What is Bleach?

Bleach is composed of sodium hypochlorite (NaClO). For chemistry fans, its chemical formula is as follows:

Cl2 + 2 NaOH → NaCl + NaClO + H2O.

For those who don’t like chemistry, well… the formula is the same!

What’s new?

Nowadays, bleach is still used as a disinfectant. Stabilized formulas enable to combine the disinfecting ability of chlorine together with the cleaning ability of surfactants.
