Application
MV’s SulfAxTM Systems are for use in treating biogas streams from landfills to anaerobic digesters at farms, wastewater treatment facilities and food & beverage processing operations. When evaluating the best system for your project – an MV Engineer will run the Capex vs. Opex cost difference of both a SulfAx system vs. H2SPlus system to identify the most cost-efficient solution to deliver against your project requirements.
Design & Technology
The
SulfAx System is designed to optimize high capacity granular media. MV Technologies uses high-performance AxTrap granular media for its superior attributes and ease of removal. The granular media is installed in fiber-reinforced plastic (FRP), stainless steel or carbon vessels through a manway. Gas flows through the vessel (top down) and the iron oxide reacts with and eliminates the H
2S and light mercaptans from the gas. The spent media is removed through a bottom side manway on the vessel, typically with a vacuum truck. Vessels are sized for a certain gas velocity and desired bed life, depending on inlet H
2S concentration and outlet H
2S requirements. By utilizing up to a ~20 ft. bed depth, media life can be adjusted, depending on available pressure drop. Additional vessel designs for the media are available and range from drums to roll-off style vacuum boxes.
- Different formulations of the media are available based on application and the presence of varied constituents in the gas such as non-methane VOC's and siloxanes.
- Effectively removes H2S with or without O2 in the gas – and based on the amount of O2 in the gas – removal efficiency of up to 20 lbs. of H2S per cubic foot of media.
Performance & Benefits
Performance & BenefitsThe SulfAx System is superior to the other leading granular media based systems in the following ways:
- Lower pressure drop.
- The spent media can be vacuum removed even if O2 is present and without the need for water. This makes changeouts safer, quicker and easier.
- The unique iron-oxide matrix of the AxTrapTM media avoids the excessive heating and combustion commonly found with other spent iron-oxide media (both on combustible and non-combustible substrates).
- Injection of small amounts of air may improve efficiency by as much as 50% or greater.
- Not affected by free liquids.
- Does not contain crystalline silica, commonly known as “quartz” that is known to cause cancer (a carcinogen) which is OSHA hazardous when present above a level of 0.2% by weight.

SulfAX Systems FAQ
What is the Primary Purpose of the SulfAx™ System?
The SulfAx™ System is designed to remove H2S, or hydrogen sulfide, as efficiently as possible from landfills, biogas streams, wastewater treatment plants, food and beverage processing pans, and various industrial environments. SulfAx™ System's role is to ensure that all biogas encountered is purified to meet industrial, environmental, local, state, and federal standards and regulations while reducing maintenance costs and protecting the investment you've made into your SulfAx™ System.
What are Common Applications Associated With the SulfAx™ System?
SulfAx™ Systems are used in several industries, ranging from food and beverage processing to agriculture, wastewater treatment plants, and even landfills. The system is developed to reduce biogas and ensure a clean and healthy surrounding environment while maintaining environmental compliance.
How is the SulfAx™ System Different From Alternative Solutions on the Market?
SulfAx™ System was designed to be as highly effective as possible around high-capacity granular media, offering easier media exchange, lower pressure drop, and improved efficiency. The SulfAx™ System works flawlessly even when in the presence of free liquids and oxygen. The unique iron oxide formulation reduces the risk of your system heating, which is common with traditional media removal solutions.
How is Oxygen in the Biogas Stream Handled With SulfAx™ Systems?
The SulfAx™ System is effective and efficient whether oxygen is present in the gas stream you're treating or not. Adding small amounts of oxygen to the SulfAx™ System can actually increase the efficiency of H2S removal by up to 50%. This allows for even further improvements to your system's performance without negatively affecting existing media.
What Vessels Are Used in SulfAx™ Systems?
SulfAx™ System uses vessels made from several materials, including carbon, stainless steel, FRP, or fiber-reinforced plastic, depending on your specific requirements and application. Your environment's gas composition and needs will help determine which materials are ideal for your SulfAx™ System solution.
How Does the AxTrap™ Media Work to Remove H2S?
The SulfAx™ System uses AxTrap™ media to aid in the process of removing H2S from the targeted biogas stream. Using AxTrap™ is highly effective. With the use of high-quality AxTrap™, it's possible to remove up to 20 pounds of H2S per cubic foot of media (this will also vary based on the oxygen content found in the gas stream itself).
Can the SulfAx™ System Handle Different H2S Concentration Levels?
Yes. The SulfAx™ System was developed with a wide range of H2S concentration levels in mind. The media bed depth and vessel can be freely adjusted to suit the inlet H2S concentration and desired outlet levels. Adaptability and flexibility make the SulfAx™ System an ideal choice for locations in which H2S levels typically fluctuate or change unpredictably.
Is the AxTrap™ Media Safe and Environmentally Friendly, Even During the Disposal Process?
Yes, the AxTrap™ media is designed to be safe to handle and dispose of, regardless of your surrounding environment or the industry you're working in. AxTrap™ does not contain known carcinogens such as crystalline silica, which is found in many alternative media sources available today.
How is AxTrap™ Media More Efficient?
AxTrap™ media is developed with a unique chemical structure, including iron oxide, that prevents combustion and excessive heating (that may occur with alternative iron oxide-based products). The use of AxTrap™ media is a way to maintain peace of mind, knowing that your environment is safe whether combustible or non-combustible substrates are present.
