Everything You Need to Know about Lift Station Odor Control Systems in Wastewater Management

Lift station odor control systems play a critical role in the wastewater management process by transporting sewage and waste to the main treatment facility. However, when left unattended, lift stations can produce foul odors that cause significant problems for nearby residents, businesses, and the environment.


Therefore, implementing a lift station odor control system is essential to ensuring a clean and healthy community. In this article, we will delve into the various options available when it comes to lift station odor control systems and how they can benefit your community.


1. Chemicals and Filters

One popular option for lift station odor control systems is the use of chemicals and filters. Chemicals like sodium hypochlorite and potassium permanganate are injected into the sewage to address odor-causing agents.


This method also includes action-driven eyewash systems and activated carbon filters to reduce odor emissions. These chemicals and filters work together to neutralize gases, eliminate odor, and minimize any oxygen depletion that may be hazardous to staff and nearby residents.



2. Biofilters

Biofilters employ natural and organic processes to eliminate odor through microbial activity. They provide an excellent method for wastewater management lift stations, sewage treatment facilities, and industrial plants with high odor emission discharge rates.


Although biofilters require initial investment in setup, it's a practical and environmentally friendly option. This lift station odor control system uses compostable organic media to create a simulated environment for microbes to remove odor-causing agents. Biofilters are known to be low maintenance, easy to operate, and can work for decades when successfully operated.



3. Chemical Injections

Chemical injection systems are similar to filter media systems but put chemicals directly into the lift station tank to break down and eliminate odors. Some commonly used chemicals in this method include hydrogen peroxide, chlorine dioxide, and NaOCl. Although the effectiveness of chemical injections varies, it can be a cost-effective lift station odor control system solution for small lift stations.



4. Carbon Scrubbers

Carbon scrubbers use activated carbon beds that capture and eliminate organic compounds that create foul odors. As air passes through the carbon bed, the organic compounds attach to the activated carbon, leaving the air clean and odorless.


Since all the carbon was used to capture organic compounds, it needs regular replacement. Carbon scrubbers are typical for the industrial sectors, but they can be adapted for lift station odor control systems.



5. Hyper-Concentrated Matrix Deodorization

Innovative companies manufacture hyper-concentrated matrix deodorization systems exclusively for the wastewater management industry. It includes advanced chemistries that change malodor to inactive compounds, without covering the odor.


The effects of malodors removal continue for weeks, which means that the lift station odor control system requires fewer applications at each lift station. This method is effective, cost-effective, long-lasting, and environmentally friendly.



Lift station odor control systems can produce adverse effects on nearby residents' standard of living and decreased environmental quality. That's why it's essential to have a dependable and accurate odor control system.


Selecting the right lift station odor control system ensures the safety of staff, protects the environment, and offers a better living environment and quality of life to the community.


With so many lift station odor control system options available, selecting the appropriate match for your lift station depends on the application, system longevity, convenience, environmental impact, safety, and cost-effectiveness.
