![]() ![]() The saturation level is determined by the concentration found in the air. The saturation level is normally expressed in g/kg of activated carbon. If the company regenerates the activated carbon itself, then this is referred to as regenerative adsorption. If replaced, the saturated activated carbon is normally returned to the supplier, who disposes of it as (chemical) waste or regenerates it. Once the activated carbon’s saturation level has been reached, it is replaced or regenerated. The gas stream is passed through the activated carbon, where the to-be-removed components bond with the activated carbon via adsorption, until it is saturated. Via specific treatments one creates a particular pore structure which determines the adsorption capacity and adsorption properties of the activated carbon. Activated carbon is made from materials containing amorphous carbon, such as wood, coal, peat, coconut shells… It is formed via a thermal process, where volatile components are removed from the carbon-laden material (raw material) in the presence of oxygen. The internal surface is ideal for adsorption. H 2S, NH 3, metals, odour,… with specific carbon typesĪctivated carbon is a microporous inert carbon matrix with a very large internal surface (700 to 1 500 m²/g).Synonyms, abbreviations and/or process names ![]()
