Web28 dec. 2000 · Hydrogen sulfide (H2S) gas typically is formed in wastewater collection systems that are conducive to creating septic conditions. Collection systems in warm climates that have a flat grade or do not have the flow-through velocities (minimum two feet per second) to prevent the stagnation of fluid, allow the septic conditions to occur. Web1 jan. 2024 · SRB produce hydrogen sulfide that reacts with the cationic metals and generate highly insoluble sulfides of metal [107]. Even uranium can be reduced in a process of dissimilatory metal reduction by some SRB species [108]. Colorless aromatic amines are formed by the ability of hydrogen sulfide to degrade the N≡N bond.
