ClO2 is an oxidizer, so inherently, it is corrosive; however, at our treatment levels (extremely low residual of ClO2) our clients do not experience corrosion issues. A great perspective on this fact is that we have units in hospitals to control legionella in drinking water through copper piping and we do not experience corrosion. If anywhere, we’d see corrosion in copper.
On the Oil and Gas side we have treated water for thousands of hydraulically fractured wells and have never experienced corrosion…in fact, due to the elimination of bacteria and H2S, we see corrosion decrease.
