Foul odors at wastewater treatment facilities are a nuisance and can be a danger to public health. Odors originate as the organics in the wastewater breakdown, releasing a smell like rotten eggs, decaying vegetation, ammonia and more. Wastewater odors can be detected even at extremely low concentrations.
Evoqua provides odor control solutions that eliminate odor complaints and protect public health

While organic and amine odors can be a nuisance, the primary wastewater odor of concern is hydrogen sulfide gas (H2S).
