Producing ClO2


A review of Purate® chemistry

For all of the chemists and engineers in the room, back to the periodic table of elements and stoichiometry.

Purate - High Efficiency

Purate ClO2 chemistry highlights the reduction of sodium chlorate with hydrogen peroxide under acidic conditions to produce chlorine dioxide (ClO2). It’s made easy with our pre-blended Purate solution.

Competitors - Low Efficiency

Some chlorite-based generators can achieve 95% efficiency when properly calibrated. However, three-chemical generators (sodium chlorite + hypochlorite + HCl) quickly lose performance and require frequent adjustments and calibrations. As a result, they typically operate with lower efficiency.

One particular chlorite technology (sodium chlorite + HCl) can operate with high efficiency but with a low yield. Inherent in the chemistry is the need to use 5 molecules of sodium chlorite to produce 4 molecules of ClO2, making 80% the maximum possible yield. Because of low yields, this technology is economically limited to small accounts, typically less than 1 kg/hr.
