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 adsorption.

Thermal Regeneration of Activated Carbon EPA

Currently, high temper- ature regeneration of activated carbon is employed and temperatures ranging from about 200 to 1800F are used to achieve 95 to 100 percent regeneration (31). The high temperature regeneration process requires either a multiple hearth furnace or rotary kiln equipment.
