descon® Aktivkornkohle SBK814 is a highly active granular carbon that is very suitable for all areas of water treatment due to its excellent mechanical properties and very high adsorption capacity. Granular activated carbon is produced from selected coconut shells and thermally activated with steam under strictly defined conditions. Activated carbons based on coconut shells are characterized by a high purity of the end product, an exceptionally high hardness and a high activity. Granulation: 1.4 - 2.5 mm
