H2S Removal by aeration

[Nena04]

I am trying to calculate how much air I should feed to remove hydrogen sulfide. Will air alone, without mixed liquor, work to release the H2S? How do I calculate the amount of air required?
I appreciate any help!

Your post mentions mixed liquor. That is a term normally associated with wastewater treatment.

Thank you, bimr!

This is for wastewater treatment. I figure I am in the wrong activity.

Thank you!

As to wastewater, the normal amount of air that is used for mixing the mixed liquor will provide adequate aeration.

I did some work at a tannery that uses sodium sulfide as part of the tanning process. The sulfide is instantly oxidized to sulfate in the activated sludge process. The activated sludge process has an inherently large capcity to make the conversion to sulfate.

This can be proven by measurement of the sulfide in the effluent.
