Frequently Asked Questions

Chlorine dioxide when handled, generated, and applied correctly, is safe to use with the right expertise for its chemistry, safe equipment design, and training support. For more than 70 years, International Dioxide has safely produced chlorine dioxide on-site for thousands of organizations and for a variety of applications.

Chlorine dioxide is usually produced as a gas dissolved in a water solution starting with a sodium chlorite solution and one of the following methods; reaction with chlorine gas, or reaction with sodium hypochlorite and an acid, or reaction with an acid, typically hydrochloric acid. Efficient generation of chlorine dioxide is reliant on proper precursor ratios and mixing for a given method.

Chlorine dioxide is used in a wide variety of food, industrial, oil & gas, and municipal drinking water applications around the world for disinfection and oxidation purposes. It replaces traditional chlorine, bleach, or other biocides — that produce undesirable by-products during the disinfection process — in order to meet stringent regulatory compliance requirements.

Chlorine dioxide is almost exclusively produced on site due to the amount of ClO2 typically required for an application. This is in conjunction with the elevated cost of shipping 99.7% water as a hazardous substance and potential safety issues in the event of a transportation incident.
