Which chemical is used for odor control in a sewer system?

Hydrogen peroxide is utilized for odor control in sewer systems primarily due to its strong oxidizing properties. When introduced into the wastewater, hydrogen peroxide reacts with the compounds in the sewage that are responsible for unpleasant odors, effectively breaking them down and neutralizing the smell. This is particularly useful in reducing hydrogen sulfide's presence, a common contributor to foul odors in sewer environments.

Hydrogen peroxide not only controls odors but also aids in enhancing overall water quality by reducing organic materials and aiding in the disinfection process. Its application helps in maintaining more acceptable conditions within the sewer systems, contributing to improved public health and environmental outcomes.
