UV light source.
Increasing density of population gives rise to the spread of germs and viruses. Disinfecting with UV light has proven to be a reliable and environmental friendly process. Unlike conventional mercury discharge lamps, the new form of UV light has a broad range of different wavelengths. The UV-spectrum has been tailored to reach maximal germicidal effect.
In cooperation with a European industrial partner, we have succeeded in developing a novel type of high performance UV light source for the sterilization of water. The UV light in this application is emitted by a plasma, which is stimulated by microwaves.
Advantages:
- Reliable and efficient sterilization of high volume throughput
- Reduced fouling and reduced cleaning expenditure due to elimination of “high peaks”
- No wear because free of electrodes
- Easy to maintain because the active electrotechnical components are located outside those parts of the apparatus which are in contact with the medium
- Free design of shape of light source
