H2S Odor Control Systems

OdorFilterTM Systems

MV Technologies OdorFilterTM Systems are designed to optimize the performance of dry scrubber technologies to neutralize malodorous sulfur bearing compounds and H2S vapors while ensuring the most cost-effective solutions based on unique system parameters.


The result is that the odors produced by H2S are often eliminated to the point that they are no longer noticeable to the average person.


These scrubbers can help reduce customer complaints and ensure compliance with local regulations for businesses and many industrial operations. In many cases, installation of these types of systems is required by federal, state, and/or local laws.


How do H2S Scrubber Systems Work?


The odor control system works by exposing the H2S to a catalytic converter, which breaks down the gas into harmless sulfur dioxide (SO2) and water vapor. 

MV Technologies offers both enhanced iron sponge-based (OdorFilterTM) and granular-based (OdorFilterTM-G) odor control systems to manage mercaptans and most sulfur-based compounds. Our systems are engineered to optimize a single media or combination of media for maximum efficiency, safety and results.

OdorFilter Systems can be applied to virtually any process that emits hazardous gases like H2S, mercaptans or carbonyl sulfides. We offer SOLUTIONS including but not limited to the following applications:

  • Asphalt and Petroleum Transport and Processing
  • Agricultural Processes
  • Food & Beverage Production & Processing
  • Landfill Gas
  • Pulp and Paper Mill Processing
  • Tanneries
  • Wastewater Treatment Facilities


What Are the Key Components of an H2S Scrubber System?


An H2S scrubber system consists of several key components. These include an inlet, a scrubber, a blower, a venturi, a scrubbing media, and an outlet. While it isn't necessary to understand exactly how the system works in order to have it installed in your operation, a basic understanding of the essential parts helps a lot when communicating with our engineers.


The system starts at the inlet or the point at which the contaminated media enters the system. From here, the media travels to the scrubber, where the chemical absorbent material is housed. Then, the blower helps to draw the media into the scrubber and create a vacuum. The venturi helps mix this media and the absorbent scrubbing material, which can be either dry or liquid. Finally, the outlet is the point at which the clean media is released into the environment or back into a commercial or industrial processing system.


Choosing an H2S Odor Control System


When selecting an H2S odor control system, it is important to consider the size and scope of the area that needs to be treated. If the area is large, a more powerful system may be needed. Additionally, it is important to consider the type of H2S present in the material that is being scrubbed. Different systems are designed to treat different types of H2S.


Configurations vary, based on application and can be skid or trailer-mounted or as simple as a single overpack drum. MV can design and supply dedicated blowers or work with existing vapor recovery systems. OdorFilter™ Systems are stable, high-impact solutions that are far superior to using activated carbon alone, in cost performance for the removal of H2S, mercaptan-based odors and visible blue/grey smoke.

  • Eliminates odors from H2S
  • Reduces operating costs and increases time between service cycles
  • Landfill ‘friendly’ or completely biodegradable


Fortunately, the design and installation experts at MV Technologies have years of experience in identifying the type of H2S present in a system and selecting the right type and size system to deal with it. If you're unsure of your system needs, give us a call.


Installing and Maintaining an H2S Odor Control System


Installing an H2S odor control system is relatively simple. The system will need to be connected to the existing ventilation system, and the catalytic converter will need to be placed in the air stream. Additionally, the system will need to be maintained, which may involve replacing the catalytic converter periodically.


Maintaining an H2S odor control system is important for ensuring it continues working effectively. The catalytic converter should be replaced periodically, and the system should be inspected regularly to make sure it is functioning properly. The system should also be checked for leaks or blockages, and the air filter should be replaced regularly. Regular maintenance will help to ensure that the system continues to reduce the amount of H2S in the air.

MV Technologies Preferred Media:

  • BAMTM enhanced iron sponge media MV modifies commercially available iron sponge and markets it as B.A.M. (bio-active media). MV purchases standard-grade iron sponge products from a commodity supplier, and enhances that material with biological agents to produce a more reactive and effective media.
  • AxTrapTM high capacity granular media MV Technologies is a distributor of AxTrapTM media products. AxTrapTM media is the exclusive product of Axens with USA and foreign patents granted and applied for. AxTrap is a trademark of Axens, all rights reserved.
