Your plant’s reputation in the community could hinge on odor control efforts.

Q: What makes wastewater treatment plants stink?

Any wastewater treatment process has the potential to generate and release nuisance odors to the surrounding area — especially when tanks and lagoons are left uncovered. These odors can negatively affect your reputation and relationship with the community, as well as the everyday job satisfaction of plant workers.

Foul odors within raw wastewater typically originate from the anaerobic decomposition of organic compounds. A natural byproduct of anaerobic digestion is hydrogen sulfide (H2S), which gives off a strong rotten-egg smell. Due to its low solubility in the wastewater, it is released into the atmosphere, producing an offensive odor.

Q: How can foul odor be controlled?

Geomembrane Technologies Inc. (GTI) is often asked to provide recommendations on how best to control these nuisance odors. There are many odor control technologies in the marketplace, and no one reigning solution exists. We recommend a simple approach: Seal your wastewater treatment tanks/lagoons with a gastight cover solution. Covering these tanks will reliably prevent diffusion of odor vapors. Escaping odor vapors can be contained and evacuated for further treatment.
