Understanding Hydrogen Sulfide (H₂S): What It Is and How to Eliminate It

Hydrogen sulfide (H₂S) is one of the most common and most dangerous gases in wastewater treatment. It smells like rotten eggs, corrodes infrastructure, and creates serious health risks. Let’s break down what it is , and how IronOx helps eliminate it.

Where Does H₂S Come From?

H₂S forms naturally in anaerobic (low oxygen) environments, especially where organic waste is present. In wastewater systems, that includes:

• Lift stations

• Manholes

• Sewer force mains

• Wet wells and pump stations

• Septic tanks

• Sludge digesters

  
  

Why It’s Dangerous

• Odor Nuisance: Even at low levels, H₂S causes strong, unpleasant odors that trigger complaints.

• Corrosion: H₂S reacts with water and oxygen to create sulfuric acid, which eats away at concrete, rebar, and electrical components.

• Health Risk: At higher concentrations, it can cause eye irritation, dizziness, and respiratory problems. At very high levels, it can be fatal.

  
  

How IronOx Stops It

The IronOx system filters vented air through Brimstone™ Media. As H₂S passes through, it’s chemically transformed into non-toxic, odorless compounds. This process happens instantly and without power.

Benefits of IronOx:

• No fans or electricity required

• Works passively 24/7

• Easy to replace media every 6-8 months

  
  

H₂S might be invisible, but its impact is obvious. IronOx helps stop the problem at the source.
