Ultra violet rays emitted at 254 nm generally known as UVc are capable of destroying living micro organisms and notably bacteria, viruses, fungi and algae. UVc rays act directly on organisms' DNA.

• A system that avoids the use of chemical products:
- it is therefore ecological and has no impact on the environment
- it does not create harmful sub-products
- it enables compliance with the European Directives related to the use of biocides

• A physical active agent:
- it does not modify the treated fluid's physico-chemical balance
- there is no risk of excess dosage
- no sub-products are formed

• It may be used in combination with other types of treatment without any constraints:
-filtration
- softening and demineralisation
- inverse osmosis
- biological treatment
- combination of H2O2/UV and ozone/UV.

• Investment and maintenance costs are low:
- easy installation
- maintenance is limited to cleaning and UVc ray lamp replacement

• Drinking water

• Industrial process water:
- foodstuffs
- pharmaceuticals
- cosmetics
- glassmaking

• Water for technical applications:
- cooling water
- swimming pools
- air conditioning and fine spraying
- farm fish

• Maintaining quality of stored water

The UV dose corresponds to the UV energy that a living micro-organism has to absorb in order to be destroyed.
The table below presents the UV doses required to kill 99.9% of micro-organisms. (those are only examples).

• Computer Aided Design and Manufacture
• Laser cutting
• Soldering under a controlled atmosphere
