Although many marine aquarists use activated carbon few know what is being removed or how carbon is beneficial to the marine aquarium. Then the manufacturing processes will ... The marine aquarist cannot reactivate carbon at home. Reactivation requires very high heat in a controlled environment to restore the sorption sites.

REACTIVATED CARBON: (PDF File)
Siemens Water Technologies can reactivate carbons that are classified as hazardous, on the Federal level as well as CA state hazardous level, at one of our regional reactivation plants located across the US. Each spent carbon is different and prior to accepting for transfer a profile must be completed.

To reactivate carbon bed 20, valves 40 and 42 are closed, and valve 46 is opened to permit drainage of water from tank 12. When the water level in tank 12 has drained down to a height of approximately one inch above level 22 of carbon bed 20, valve 46 is closed preventing further drainage of water from tank 12.

and how to better thermally reactivate activated carbon. He is also exploring various means of regenerating spent activated carbon, including thermal, and quasi-thermal processes. Dr. Cannon has also conducted extensive study of the nature of natural organic matter that passes through various water treatment unit processes.

Reactivated carbon is used carbon, processed under specific conditions to remove the contaminants that were absorbed in prior use. As some of the physical structure is lost during the process, the carbon loses a percentage of its original pore structure, thereby reducing its overall efficiency.
