Chlorine Dioxide

Chloride Dioxide (ClO2) is used in drinking water treatment as a disinfectant and oxidizing 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.

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.
