6.1 Application examples
UV disinfection is a method for inactivating microorganisms in the water and thereby disinfecting the water
without using chemicals and without influencing the odour and taste of the water. It is also a non-selective
disinfection technique where the dose must be adjusted depending on the type of microorganism. As far as
known, there are no UV-resistant microorganisms. Cryptosporidium and Giardia protozoa are known to
have very high chlorine and ozone resistance but only require a low UV dose for inactivation.
UV disinfection can be applied effectively, including applications in:
- Drinking water;
- Waste water;
- Swimming pools (private);
- Soft drink industry;
- Breweries;
- Aqua culture;
- Horticulture;
- Food industry:

- Offshore Industry, injection water;
- Electronics industry;
- Automotive industry;
- Irrigation water;
- Maritime applications;
- Paper industry;
- Petro and chemical industry;
- Snow production machines;
- Mobile applications such as in trains.
Furthermore, with correct dimensioning (higher UV doses than are necessary with disinfection), UV
radiation can also be used for oxidative applications. Due to photolysis properties of UV radiation, UV
systems can be used very effectively in the reduction of bound chlorine (chloramine) that has the so-called
"swimming pool" odour and e.g. cause red eyes in swimmers.
UV radiation can also be used as a catalyst in so-called "Advanced Oxidation Processes" (AOP). The UV
radiation is used to oxidize an oxidizing agent (e.g. H
2
O
2
, O
3
, Cl, etc.) by means of photolysis. This process
releases hydroxyl radicals (
●
OH) that have the second highest oxidation potential (2.80 V) which micro-
contaminants can be broken down in the water.
