Typical applications for impregnated carbon

Hydrogen sulfide

Mellifiq offers premium impregnated carbon for hydrogen sulfide applications, for biogas plants or wastewater treatment plants where pungent odor problems may cause serious challenges. Depending on the concentrations, Sulfisorb Plus, Sulfisorb 20 or KAL-3000 may be considered for reliable problem solving.

Hydrogen fluoride

Hydrogen fluoride (HF) is a polar compound that requires impregnation to enhance its removal, using specialized activated carbon such as SORB17

SOx and NOx

NOx and SOx gases are a general term for oxidized nitrogen or sulfur based gas, where a combination of technologies are normally required in order to facilitate complete removal. Impregnated activated carbon is effective in adsorbing NO2, with pre-oxidation as a requirement if NO is present. Special impregnation like potassium carbonate or copper oxide are applicable through for example impregnated coconut shell based carbon COC-CU50. It is also a perfect ozone destructor material suitable for a combination of pre NO ozonation and subsequent NO2 adsorption.

Cyanides

Hydrogen cyanide or cyanide-metal complex are challenging compounds which are present in the mining industry or metal plating industry. Granular activated carbon (GAC) can be used to effectively adsorb cyanide compounds in water phase or gas phase using special impregnation. Mellifiq can facilitate this need with our COC-Cyansorb carbon type.
