Removal of DO from Brine Solution
Removal of DO from Brine Solution
(OP)
I'm reviewing options for removing dissolved oxygen from a brine waste stream (25% solids) to prevent possible downstream corrossion or bio issues.
What would be the best chemical for this application? I've seen reference to sulphide.
Any help on a balance equation for commention DO removal would be appreciated.

RE: Removal of DO from Brine Solution
You are referencing a chemical called sodium sulfite that is commonly used as a oxygen scavenger in boilers. That chemical is only used after a vacuum deaerator is used to remove the bulk of the oxygen. It would probably be expensive except for small quantity usage.

If you are concerned regarding corrosion, the cheapest approach is generally an acid such as sulfuric to raise the pH. For bio issues, the common treatment for control is chlorination.
