Counterflow oxidation was developed and evaluated for treatment of organics that adsorbed in/on granular activated carbon(GAC). This reaction is a method that destructs and removes organics adsorbed, at the same time, regenerates waste carbon, uti lizing a self-sustained flame which propagates itself ina direction counter to the oxygen flow. The results showed that the mass loss of carbon and flam temperature were strongly dependent on the flow rate of oxyen, adsorptive capability of regenerated carbon completely was recovered, as well as destrution and removal efficiency of thermally stable PCBs was achieved with the value of better than 99.99%.
