Hydrogen Sulfide (H₂S) Treatment: Stopping the Rotten-Egg Smell at the Source

Hydrogen sulfide is produced when sulfate-reducing bacteria break down organic matter in oxygen-poor environments — ejector pits, lift stations, sewer force mains, grease interceptors. It is responsible for the rotten-egg smell, eats through concrete and metal at the pipe crown, and is hazardous to workers above a few ppm.

Why venting doesn't solve it Venting moves the problem. The bacteria keep producing H₂S, and the building keeps paying for corrosion repairs on manhole covers, pump impellers, and stack vents.

Source treatment Continuous dosing of biological or chemical sulfide scavengers calibrated to the system's load. The treatment binds sulfide before it volatilizes, protecting both air quality and infrastructure.

What gets measured H₂S meters at the discharge point, pump runtime, and corrosion rate on sacrificial coupons. Buildings on a documented program have the data to defend their compliance posture.
