Sewer Odor Control in Wastewater Plants

Every water reclamation plant should do its part to be a good neighbor and properly manage sewer odor control. Through taking proactive steps and being aware of what's needed to maintain sewer odor control, keeping things in order is very achievable.

When regularly monitoring existing treatment facilities, the pipeline network, and pumps stations, sewer odor control can be properly maintained. As part of a proactive approach to addressing odor problems through sewer odor control, it's important that odor control design is implemented into new and existing sewer systems. Just a few some of the technologies and methods that can be used to reduce and/or neutralize unpleasant odors.



Sewer Odor Control In Wastewater

The problem with foul odors emanating from wastewater treatment plants is a common one. There are many causes that sewer odor control issues might arise, but the solutions can be complicated. Some communities blame private industries like food processing plants and industrial farms, while others might blame the municipal system. No matter the source, communities of every size battle against complex and undesired chemical reactions.



What Causes Required Maintenance for Sewer Odor Control?

Many people compare the odors produced by wastewater treatment plants to rotten eggs, ammonia, and other organic substances. These smells are usually caused by the anaerobic degradation of organic materials. Most people associate these facilities with a strong smell, which is caused by hydrogen sulfide (a by-product from decomposition), and the biggest signifier that sewer odor control needs immediate maintenance.


Other compounds that can cause odors are amines, mercaptans, and other compounds rich in sulfur. These smells can only be worsened if preventive measures for sewer odor control is not taken. The problem can be exacerbated by weather conditions such as high winds, heat, humidity, and high temperatures.


Most complaints are received by wastewater plants during summer, but it is important to maintain sewer odor control within the plant throughout the course of the year.



How Can Wastewater Plants Provide Sewer Odor Control?

It is important to quickly investigate serious odor problems. Although the initial task is to find the source of the problem, odors can be released at multiple stages in the water treatment process. After identifying the source, the best sewer odor control measures are determined based on several factors.


Deodorizing mists are often used by wastewater plants to solve the problem. However, it can mask the true problem. Although adding chemicals or biological agents to the water during treatment can help neutralize odors in some cases, sometimes simple modifications to the process are the best way to get rid of them and maintain sewer odor control.


Sealing tanks with a cover is likely the best way to prevent bad odors from entering the air. This can lead to worker complaints. Another option is to capture the airborne pollutants and treat it with liquid redox technology, a bio-filter, carbon filter or wet air scrub, which can be a really effective form of sewer odor control.
