Wastewater odor is a nuisance and can be a danger to public health. Odor originates as the organics in the wastewater breakdown, releasing a smell like rotten eggs, decaying vegetation, ammonia and more. Evoqua provides a broad range of solutions for effective wastewater odor control.
The chart below provides details of the most common odorants found in wastewater. While organic and amine odors can be a nuisance, the primary wastewater odor of concern is hydrogen sulfide gas (H2S). Concentrations of H2S as low as 0.0005 ppm can trigger odor complaints from the surrounding community.
