Purate^® - No Chlorine Gas Used or Made

Purate^® technology does not use chlorine gas as a feed chemical and does not produce chlorine as a byproduct. Avoiding the use of chlorine gas eliminates the concerns and expense associated with its use.

Competitors - Chlorine Gas Process

The chlorite + Cl₂ (gas) process uses an excess of chlorine to the reactor. So not only is the handling of chlorine gas required, but the product ClO₂ solution contains chlorine, too.

The chlorite + HCl + Hypo process obviously does not use chlorine gas as a feed, but the HCl and Hypo are used to make chlorine for reacting with the chlorite. Excess Hypo and HCl are fed to the reactor resulting in excess chlorine which ends up in the product ClO₂ solution.
