| Water-disinfection ist the elimination or deactivation of organisms that cause contagious diseases. Degermination is the elimination and seperation of microorganisms – especially bacteria – through physical or chemical procedures. |
| Usual degermination processes are water-treatment with ozone, chlorine dioxide, chloric gas or dechlorinated chemicals as well as UV-radiation as a physical preparation procedure. |
| Which procedure is chosen is depended on water-quality, amount and additional preparation methods. |
| There is a variety of techniques to disinfect water. Every technique has its specific advantages and its own application area. The chart shown below contains advantages and disadvantages of various techniques: |
