SulfAxTM Systems
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 H2S 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 H2S concentration and outlet H2S 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
The 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.
