    • Adsorption / Active Carbon Lenntech

      Activated carbon adsorption. Adsorption is a process where a solid is used for removing a soluble substance from the water. In this process active carbon is the solid. Activated carbon is produced specifically so as to achieve a very big internal surface (between 500 1500 m 2 /g). This big internal surface makes active carbon ideal for
