Odor generated from wastewater systems is from hydrogen sulfide (H2S), which is released in the form of a gas.  In addition, hydrogen sulfide can lead to corrosion in collection systems and wastewater plants, leading to dangerous leaks. Several emission sources need odor control equipment, e.g. such as pump stations, wet wells, sludge dewatering, manholes, air valve chambers etc. Sewage and Effluent odor consists of mainly hydrogen sulphide & H2S is dangerous to be released to the environment. Hydrogen sulphide,  the gas,  also contains organic sulphur components  (mercaptans,  hydrocarbons)  and ammonia.

Odorous compounds such as VOCs (Volatile Organic Compounds), H2S and Volatile Fatty Acids (VFAs), can be found in kitchen ventilation and a wide array of different industries. Although the odors do not necessarily impose physical health problems, malodors disturb the surrounding, resulting in complaints towards the source.

Odorous VOCs can originate from microbial or thermal decomposition of organic matter, which is a common process in breweries, wastewater treatment plants, cooking and food industries.

The sources of H2S emission are similar to the ones of VOCs, with the main difference of the presence of sulfur compounds in the source substrate. For example, the organic material in food industries and wastewater treatment plants contains a significant concentration of sulfur compounds, leading to H2S emissions. H2S is also common in breweries, biogas production plants, due to the anaerobic reduction of sulfur compounds in the bioreactors or digesters.
