How can ultraviolet light fight water shortage?

Ultraviolet water purification is an effective countermeasure against water shortage. It can help to purify water in situations without a clean water supply.

Biological processes inside of microorganisms enable the ultraviolet water purificator to work. The lack of proper mechanisms of resistance against Ultraviolet light renders them unable to reproduce and cause infections.

Ultraviolet light is electromagnetic radiation of wavelengths just below the spectrum of visible light. It is subdivided into three groups: UV-A, UV-B, and UV-C. Its last region has germicidal properties for disinfection. The sun also emits UV light, but in contrast to the UV-A and -B rays the UV-C fraction is virtually completely absorbed by the atmosphere. This is why microorganisms didn’t develop proper mechanisms of resistance against UV-C.

As a result enzymes responsible for unwinding and copying the DNA during replication are not able to function anymore. This renders the microorganism unable to reproduce and cause infections. That’s why ultraviolet rays penetrate harmful bacteria and viruses in water and destroy illness-causing microorganisms.

The name "Einhackglas" is linked to the German word "Einmachglas" (English: jar). The syllable "mach" refers to the jar's ability to preserve groceries. It is exchanged by "hack".

The collaboration with economics and electrical engineering students resulted in new business models and working prototypes. Thanks for the great teamwork, Denis Jagodic, Jessy Rudorf, Erik Rockoff, Simon Jenewein, and the OpenLicht Team of Infineon.
