Chlorine Dioxide In Water Treatment
Chlorine dioxide is an extremely reactive gas, which – because of its instability – cannot be stored, and must only be produced in the required quantities in special generators on the site
where it is to be used. Chlorine dioxide offers a number of advantages for water disinfection compared with other disinfectants such as chlorine.
Advantages of chlorine dioxide versus chlorine
- Disinfection power is independent of pH.
- High residual effect due to long-term stability in the pipeline system, thus microbiological protection for many hours to days
- Reduction of the biofilm in pipelines and tanks, hence reliable protection of entire water systems against legionella contamination.
- No reaction with ammonia or ammonium, thus full disinfection power of chlorine dioxide.
- No formation of chlorophenols and other intense odor compounds, which can be produced in water chlorination.
- No formation of THMs and other chlorinated hydrocarbons, no increase in the AOX value.

Chlorine Dioxide Applications
For every new project, our engineers can draw on the experience that we have continually accumulated since 1976, in the following applications:
