Odorous Compounds in Raw Wastewater
- Amines: Emit a fishy aroma, commonly related to the decomposition of organic matter.
- Ammonia: Recognized for its strong ammoniacal odor, often a result of the breakdown of nitrogen-containing compounds.
- Diamines: Produce a smell reminiscent of decayed flesh, often arising from protein degradation.
- Hydrogen sulphide: Characterized by a strong rotten egg scent, typically generated by anaerobic decomposition of organic materials.
-
Mercaptans:
- Methyl and ethyl mercaptans release a decayed cabbage odor, contributing to unpleasant smells in wastewater.
- T-butyl and crotyl mercaptans are associated with a skunk-like scent, highlighting the varied nature of these compounds.
- Organic sulphides: Create a rotten cabbage smell, indicating the presence of sulphur compounds in the wastewater.
- Skatole (C9H9N): Noted for its faecal matter odor, it is a byproduct of protein breakdown in sewage systems.
