Darco H2S is a unique product that is manufactured without the use of chemical impregnation to the surface of the carbon. It is specially developed for the removal of hydrogen sulfide, also known as H2S (the main source of sewer and septic gas odors) and other compounds commonly found in municipal odor control applications. With Darco H2S, hydrogen sulphide is removed catalytically rather than by chemical adsorption. Because of its catalytic properties, Darco H2S gives you the high loading rates of impregnated carbons without the thermal risks associated with chemically treated carbons (caustic impregnated carbons). This makes Darco H2S the perfect choice for use in sewage treatment plants and pumping stations where these compounds are typically found. While catalytic carbons cost more than standard or impregnated activated carbons, the end result is that it has the adsorbing capabilities of activated carbon without the shorter life.

Darco H2S is an non-impregnated, bituminous coal-based catalytic activated carbon which has been specially developed for removing hydrogen sulfide and sulfur compounds from air streams. It is well suited for use in sewage treatment plants and pumping stations where these compounds are typically found. Darco H2S gives you the high loading rates of impregnated carbons without the thermal risks associated with some chemically treated carbons.

H2S capacity is measured using ASTM standard method D6646-01. Testing requires passing a moist air stream containing 1% by volume H2S though an appropriately sized column (per ASTM requirements) packed with activated carbon and monitoring to a 50 ppmv H2S breakthrough. Results are reported as grams of H2S adsorbed per gram of activated carbon.

*Note: Washing Darco H2S is not recommended in most cases due to the high potential sulfur contents, which can be washed off the carbon. Proper clothing and respirator must be utilized when regenerating carbon with water.
