TECHNICAL DATA SHEET SweetAir-H2S™
Hydrogen Sulfide Odor Control
General Description – SweetAir-H2S is a unique, organic-based solid media composed of a mixture of inorganic
odor reactants. This non-hazardous product is made of 99% natural and re-cycled products to help protect our
environment while providing the best odor control available. Hydrogen sulfide is safely and irreversibly reacted away by
special iron oxide compounds (this is not rust-impregnated wood chips). This media thrives on the wet, humid
environments commonly encountered in odor control operations as well as dry locations. The unique easy-to-handle, high
capacity, lightweight and very low pressure-drop media was specially developed for sewer-type odor control in Odor
Guard® manhole insert odor control units. The media has also proven to be the most cost-effective H2S elimination
media for other odor control applications. The media is capable of removing H2S in concentrations as high as 5,000 ppm
down to almost any desired outlet level, with loading capacities to 70% by weight, depending on system design.
Main Services
When used in the standard 3 cubic foot media basket Odor Guard system, the unit is capable of removal of 99% of up to
5,000 ppm H2S at 35 cfm on new media with a pressure drop of 1-inch W.C. This performance capability of H2S removal
combined with low pressure-drop is unique to the Odor Guard system utilizing this media. Life of the media is difficult to
accurately predict without knowing gas flow rates and H2S levels. Most Odor Guard manhole installations experience
media life of a year or more.
Application -
The media is used as part of the Odor Guard® system designed for the operating conditions common to
wet and dry manhole conditions. The Odor Guard media basket is filled to the top edge of the media basket. Inspect the
installation after about a month to see if additional media is need due to settling caused by street vibrations. Some
condensation of moisture or wetting of the media during its life is not harmful. Four pails of Odor Removal Media are
supplied with a standard 3 cubic foot Odor Guard unit. A quantity of the 4th pail remains after filling to be used later.
Storage and Handling -
This media can be stored in unopened pails for a year or more. Being DOT non-hazardous,
no special storage or inventory is necessary. This unique media has a consistent and low pressure-drop without any
special filling or handling. The lid should be replaced on opened containers for storage and use later. See MSDS for
more information.
