Chlorine Dioxide - OVERVIEW
Chlorine dioxide is an effective method of disinfection as an alternative for chlorination. It is a very good oxidant & it addresses some of the concerns with disinfection by-products. With the continuous tightening of regulations surrounding trihalomethanes (THM'S), chlorine dioxide is growing in popularity. There are some key advantages in favour of chlorine dioxide:
  • Disinfection power is pH independant
  • Long residual effect
  • No reaction with ammonia or ammonium
  • No formation of chorophenols and other intense odour compounds which can be produced in water chlorination.
  • No formation of THMs and other chlorinated hydrocarbons

Chlorine Dioxide is a very reactive gas that cannot be stored and must be generated onsite. The gas is generated onsite by combining sodium chlorite and hydrochloric acid. Metcon can provide a complete solution for chlorine dioxide generation, feed and control.
