Odors emitted from a wastewater treatment plant naturally occur due to the anaerobic treatment of the sewage waste. The most common odor is caused by hydrogen sulfide although other chemicals in smaller concentrations are also present. All of these odor-causing chemicals have very low thresholds of detection; in the parts per billion range. These odors are emitted at multiple points in the wastewater treatment process.

When a wastewater treatment plant is located near urban and residential areas odor control systems are often employed. Various methods of odor control processes can be utilized.

Wet Scrubber Treatment

To ensure complete capture of all odors, wastewater treatment facilities will put covers over the various sources where odor can be emitted; this includes such areas as the holding tanks, aeration basins, clarifiers, and sludge thickeners. The collected odorous air is then treated in various methods with the most common being wet scrubbers or activated carbon adsorbers. Sage Prime insertion flow meters are the perfect choice to make sure that the correct amount of air is being drawn from the various sources. Also, since multiple scrubbers or adsorbers are used, insertion thermal flow meters are used to balance the flow into the various units.

Odor Neutralization

Various chemicals can be used for neutralizing any odors. These chemicals can be vaporized into an air stream to disperse and then injected into the desired location. Thermal flowmeters have an important role to ensure that the proper amount of air is being used and that the air flow is evenly divided if there are multiple injection points.
