The above pictures show damage to a ductile iron force main due to hydrogen sulfide (H2S). The hidden issue for this Utility was that the line was untreated but no odor issues were present. Because no odor complaints were received due to the line’s remote location, no indicator was known regarding the damage from corrosion.
Where Does Hydrogen Sulfide Exist?
The formation of hydrogen sulfide is a result of the breakdown of organic matter by bacteria, typically in an oxygen deprived environment. These locations include:
- Municipal collection systems
- Wastewater treatment plant headworks
- Paper mills
- Rendering plants
- Food and beverage processing
- Industrial manufacturing
How Do You Treat Hydrogen Sulfide?
Preventive Chemistry
Nitra-Nox is a naturally proven solution used to prevent the production of H2S in wastewater. H2S is produced when the anaerobic bacteria feeds on sulfates. Nitra-Nox is an alternative oxygen source, preventing future production of H2S.
Features And Benefits:
- Non-hazardous
- Prevents corrosion to wastewater collection system and equipment
- Does not affect pH of wastewater
- Reduces BOD
Next Gen Corrosion Control Chemistry
Sul-Fight FX works in difficult treatment environments where H2S and sulfates exist. Its application ensures no ill effect on the wastewater treatment process.
Feed locations:
- Municipal manholes
- Collection system lift stations
- Sludge holding tanks
- Belt filter press
- Air scrubbers
- Collection headworks
