Name a common method for odor control in wastewater facilities.

The use of activated carbon filters is a common method for controlling odors in wastewater facilities due to their ability to adsorb a wide range of volatile organic compounds and other odorous substances present in wastewater. Activated carbon has a large surface area and porous structure, allowing it to capture and retain odor-causing molecules effectively. This method is often employed in treatment processes to reduce the impact of unpleasant smells during the handling and processing of wastewater.

While other methods like ozone generators can be effective, they typically require careful handling and monitoring, as ozone can be hazardous. The use of sprays may help to mask odors temporarily, but they do not eliminate the source of the odors. Changing aeration techniques can influence the development of odors by promoting aerobic digestion, but it is not specifically a standardized odor control method. Therefore, activated carbon filters stand out as a reliable and widely used solution for odor management in wastewater treatment settings.
