Overview
Wastewater plants, pumping stations, and many industrial sites release foul-smelling gases, mostly hydrogen sulfide and organic sulfur compounds. Air from these areas is passed through vessels of activated carbon before it is released.
How it works
- Foul air is collected from covered tanks and wet wells.
- Fans push it through deep beds of carbon.
- Hydrogen sulfide is adsorbed and converted on the carbon surface, and other odor compounds are adsorbed.
- Clean air is vented and the carbon is replaced when exhausted.
Why coconut shell
The small, reactive molecules behind most odors are well matched to its micropore structure.
This page describes activated carbon in general. Suitability for a specific use depends on the activated carbon grade and the system it is used in.
