Degassing / Vacuum 1

[ozfish]

Is it possible to remove Hydrogen Sulphide and or CO2 dissolved in groundwater (pH 5.4) by passing the water through a vacuum?

Sure, you can take the CO2 out. However, CO2 comes out before H2S. As the CO2 comes out, the water pH will rise and prevent the H2S from coming out.

Thanks for your reply.
Will the rise in pH prevent the H2S removal or just slow it down. What is the normal practice for removing both?

It is not possible to say how much H2S will come out. You probably would have to confirm that with a experiment.

THe only thing that can be said is that carbon dioxide comes out much more easily than the more soluble hydrogen sulfide.


You need to have the water analysis (H2S included) and flow before making any type of conclusion on the best treatment approach. The most common technique is to use aeration or degasification, and or chlorination.
