Chlorine Dioxide for industrial water systems 1

[Sweetpea]

I am looking at replacing our present Bromine dosing system with something more efficient and E friendly. UV is not suitable I'm told due to the flow rate (up to 540 m3/hr) and ClO2 has been suggested.
Questions; Will this corrode galvanised steel pipes? Will the gas escape into the factory atmosphere at normal temperatures? What water purity standard will I get with this system?

Here is website that will give you a good start on ClO2 water treatment. The site is in China but gives a pretty good assessment of the efficiency of ClO2. We had no problems with corrosion of CS with the system.
