[en] Several methods are used In the pollutant removal from Industrial and domestic wastewater. However when the degradation of toxic organic pollutants, mainly the recalcitrant is objectified, the conventional treatments usually do not meet the desirable performance in the elimination or decrease the impact when the effluent are released to the environment what takes to the research of alternative methods that seek the improvement of the efficiency of the wastewater treatment systems jointly employees or separately. This work presents a study of degradation/removal of pollutants organic compounds comparing two methods using radiation from industrial electron beam and granular activated carbon (GAC). The removal efficiency of the pollutants was evaluated and it was verified that the efficiency of adsorption with activated carbon is similar to the radiation method. The obtained results allowed to evaluated the relative costs of these methods. (author)
