How to remove H2S gas in wastewater treatment?
Thread Content
How is H2S gas removed in wastewater treatment? How do I convert between ppm and mg/m3? The 5% sodium hydroxide solution used by our unit does not yield good results when used for spraying; are there any better alternatives? Considering only the issue of removal, are there methods that can more effectively eliminate odorous gases from wastewater? If you have any recommendations for better manufacturers or equipment, I would appreciate it. Thank you to all the experts
1PPm = 1000mg/m3 = 1mg/L; after dust removal by a water curtain, activated carbon is used for adsorption.

Hydrogen sulfide gas in wastewater? Consider trying precipitation using an iron sulfate solution; sulfur ions will yield better results. If it is in the form of gas molecules, it is recommended to convert it to an ionic form before attempting precipitation.
It is a gas produced in wastewater, used to eliminate unpleasant odors
An attempt can be made by sealing the sewage tanks and pipes, using fans to draw the waste air in centrally and sending it to an absorption tower, where it comes into countercurrent contact with a mixed solution of NaOH and NaCLO for absorption and decomposition.
Photocatalysis. . . . The actual continuous operation performance is unknown. . . . mg/m3=ppm×（M/22.4）×（273/（273+t））
Thank you. I have already contacted the manufacturer and am waiting for them to conduct the experiment
I would be grateful if you could let me know the experimental results; I’m also interested in knowing the effects. Thank you very much. . . . .
Your problem is easy to solve, and hydrogen sulfide is also easy to handle. Let’s see how you handle it
