Chloordioxide in waterbehandeling

Chloordioxide in waterbehandeling

ProMinent 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 plants on the site where it is to be used. Chlorine dioxide offers a number of advantages for water disinfection compared with chlorine, the disinfectant mainly used

Chlordioxidanlage

Advantages of chlorine dioxide, particularly compared to chlorine

  • Disinfection power is independent of pH.
  • High residual effect thanks 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 chorophenols and other intense odour compounds which can be produced in water chlorination.
  • No formation of THMs and other chlorinated hydrocarbons, no increase in the AOX value.
