Which process helps mitigate odors emitted from wastewater treatment facilities?

The process that specifically addresses the mitigation of odors emitted from wastewater treatment facilities is odor control measures. These measures are designed to capture, neutralize, or eliminate unpleasant smells that can result from the breakdown of organic materials and other processes occurring in treatment facilities.

While the activated sludge process, flotation treatment, and disinfection treatment are essential components in the overall treatment of wastewater, they do not primarily focus on odor control. The activated sludge process relies on microorganisms to break down organic matter, which can sometimes produce odors as a byproduct. Similarly, flotation treatment is designed to remove solids and grease but does not specifically aim to manage odors. Disinfection treatment, which typically involves using chemicals or processes to kill pathogens, also does not address odor management directly.

Odor control measures, on the other hand, can include various strategies such as using biofilters, chemical scrubbers, and other technologies aimed specifically at reducing the impact of odorous compounds in the environment, making them the most relevant choice for mitigating odors in wastewater treatment facilities.
