Wet air oxidation (WAO) of Afyon alcaloide factory wastewater, a typical high strength industrial wastewater, was carried out. The process was performed in a specifically designed titanium bubble reactor at temperatures in the range of 140-160 degrees C. The kinetics of WAO of alcaloide factory wastewater was modeled by assuming two distinct steps. The rates of destruction were measured with respect to reduction in COD. The oxidation reaction was found to be first order with respect to COD concentration and also second order with respect to oxygen concentration in both steps. The values of activation energies were found to be in the range of 4.93 x 10(4)-7.85 x 10(4) kJ/kmol.
