Sewage and Wastewater Odor Control

Sewage and industrial plants located near residential areas can be subject to political and legal problems if these facilities produce unpleasant odors. In the case of a sewage plant and the associated collection system, chemicals or enzymes may be added to the liquid phase to prevent the formation of the odors. Mechanical changes to the sewage pump stations may also be made to reduce the odor. When these methods are not sufficient to control the odor, some form of odor control in the vapor phase may need to be applied.
