Wastewater Treatment Odor Control

Eliminate odors at wastewater facilities for workers and the community.

In the wastewater treatment industry, the biggest challenge treatment plants face is controlling wastewater odors. Many times these treatment facilities are located within communities that will be severely affected by a lack of odor mitigation. Failure to control bad odors at a facility can result in negative press, regulatory fines, and will negatively impact the lives of plant workers.

Get ahead of the issue and put your workers and community first by creating a proactive plan to mitigate and reduce wastewater odors at the source. With 25+ years of experience in wastewater treatment odor control, Ecosorb understands that each plant has unique problem areas. No matter the issue or source of your odors, our custom solutions will mitigate odors at your facility.

Why do wastewater treatment plants smell?

Many odors can be released from wastewater treatment plants. Commonly they are described as odors resembling rotten eggs, garlic, ammonia, or earthly smells. Odors that come from wastewater treatment plants are caused by the use of chemicals such as:

  • Hydrogen sulfide (H2S)
  • Sulfur dioxide
  • Skatoles
  • Indoles
  • Amines

With so many different chemicals being the possible source of odor, a variety of odor control methods are often needed and recommended for a complete odor removal.

Wastewater Facility Odor Solutions


Headworks and Primary Treatment

Hydrogen sulfide odor can be extremely toxic and flammable. Not to mention the invasive odor it emits to workers and the surrounding community. Attacking this colorless gas at the source is extremely important to the safety of your facility. Vapor or fan systems that are properly installed at the bar screens and digesters will solve any issues. Ecosorb is able to provide custom solutions that will mitigate your hydrogen sulfide odor and can be done in a cost-effective operation.

Wastewater Septage Dumping

Plants that have their industrial emissions under control may still need odor solutions for handling and transportation of raw septage. Fan or nozzle atomization systems installed near the unloading point where haulers bring septage, or downstream from this area, can provide effective odor removal.

Activated Sludge Basins

Basins holding activated sludge and wastewater are typically large, uncovered, and odor producing. Smells from these basins can freely drift with the wind into neighboring communities, leading to negative perception of your plant and potential fines. Ecosorb’s experienced engineers have developed custom wastewater treatment odor solutions focused on neutralizing odors from these basins. Protect your facility and your community and implement a custom Ecosorb solution today.

Food Processing Plants

Wastewater is a natural byproduct of food processing facilities. Not only do facility owners have to be concerned with controlling odors from processed food, but also all the odors that are associated with wastewater. Ecosorb odor control products for wastewater are approved for use outside of food processing plants and are environmentally-friendly. Let Ecosorb be an all-encompassing odor solution at your facility.

How to Use

Whenever possible, we use existing odor control hardware (e.g. scrubbers) to apply Ecosorb odor control solutions. In situations where there is no current system in place to control odors, our team designs system options.

Most facilities opt for vaporization systems, where ducting carries Ecosorb product in submicron form to the source of the odor, neutralizing it on contact. There are no nozzles to plug making this system virtually maintenance free.

Many systems are operated on an “as needed” basis, and switched on when the odor reaches a certain perceived level, while others kick on automatically based on wind direction, when air currents cause odors to travel toward neighboring businesses or residential developments.
