Abstract
The present invention provides a method for the continuous regeneration of activated carbon which has become loaded and deactivated subsequent to an aqueous filtration process, wherein organic chemical substances adsorbed on the activated carbon are oxidized and decomposed in the presence of water and oxygen by the action of hydroxide radicals. Hydroxide radicals are produced in the water by means of x-radiation in the range of from about 50 keV to about 800 keV, preferably in the energy range from about 100 keV to about 300 keV. An additional ultrasonic treatment may be employed to improve the effectiveness of the regeneration process. X-ray tube arrangements with tubular anodes are particularly suitable for use with the irradiation regeneration process.
