Chlorine Dioxide

Chlorine Dioxide is a powerful oxidising agent used for the disinfection of potable water, cooling towers, process water and food processing.

What is Chlorine Dioxide?

Chloride Dioxide (ClO2) is used in drinking water treatment as a disinfectant and oxidising agent to prevent the growth of bacteria within the distribution system.  As Chlorine Dioxide is less corrosive than chlorine, it is also often used for the control of Legionella bacteria.

Chlorine Dioxide is approximately 10 times more soluble in water than chlorine. It is not affected by pH, has an excellent residual effect, remains active for hours to days, does not interact with ammonia or ammonium and is effective in cold temperatures.

Chlorine Dioxide monitoring

Monitoring and maintaining ClO2 residual in difficult ‘dirty’ applications, including hospitals or the food industry, is vital.   Continuous monitoring and measurement ensures the effective use of chlorine dioxide for disinfection purposes, along with other applications. Under dosage can be ineffective and over dosage results in excess Chlorite by-product formation. 

ATi provides economical, reliable and reagent-free measurement solutions for water quality monitoring and controlling ClO2 treatment systems.
