Water is essential to life.
Demand for clean water is growing the world over.
Contaminated water can be treated with energetic UV radiation without adding chemicals such as chlorine or ozone.
Special UV lamps not only destroy microorganisms such as bacteria, viruses, parasites and fungi but can also decompose chemicals that are detrimental to health. Giardia and cryptosporidium can likewise be inactivated with UV light.

Advantages of Heraeus UV light:
- No influence on taste and smell

- No environmental damage
- Short irradiation time
- Effective against chlorine-resistant pathogens
- Easy handling
- Low-maintenance procedure
- Very low operating costs

Drinking water: A hygienic and safe supply of drinking water for the population is a key factor in the preservation of health and the prevention of epidemics. Drinking water can be disinfected and treated with UV light without adding chemicals.
Neither taste nor smell or PH value of the water are affected. The special added benefit: pathogens cannot become resistant to UV light.

Sewage: Municipal sewage needs to be treated and disinfected before it is returned to the hydrological cycle. Only this enables protection of rivers, lakes, groundwater and public health.

Drinking water systems for private households:
Decentralised drinking water treatment is becoming ever more important, especially in regions that are difficult to access. For example, UV light inactivates legionellae in private and public hot water supply systems e.g. for swimming pools.
Grey water: Slightly soiled waste water such as shower water can be recycled in hotels and sports complexes and used for tasks that do not require high quality, such as irrigation. In many other applications, water can be treated with UV technology, e.g. in zoos, aquariums, fish ponds and swimming pools.
