Which operational change can help in mitigating odor from a treatment process?

Implementing better cover systems is an effective operational change for mitigating odor from a treatment process. Covered systems help to contain and capture volatiles and odorous gases produced during wastewater treatment. By enclosing specific areas, such as tanks or lagoons, covers can significantly reduce the escape of odorous compounds into the atmosphere, thus minimizing the odor that can be perceived off-site.

In addition, effective cover designs can facilitate the collection and treatment of odorous emissions through odor control systems, such as scrubbers or biofilters, which can further reduce odors. This approach directly addresses the source of odors, making it a practical solution in both reducing nuisance odors and improving overall air quality around wastewater facilities.
