Mar 01, 2018· Hydrogen Sulfide (H2S) is a byproduct gas evolved during the treatment of sanitary wastewater. Due to its low odor threshold, in the part- per -billion range, the odor produced by wastewater treatment facilities offends neighboring residents. H2S may be removed from the effluent gas stream by wet, chemical scrubbing.
