OPTIMIZATION OF PHENOLIC COMPOUNDS ABATEMENT IN OLIVE MILL WASTEWATER BY FENTON'S LIKE TREATMENT WITH H2O2/Cu2+ UNDER MICROWAVE USING EXPERIMENTAL DESIGN

Abstract : This work describes the application of Fenton's like system (H2O2/Cu2+) assisted by microwaves to the removal of phenolic compounds from olive mill wastewater (OMWs). The effect of various operating conditions, namely copper ion concentrations (X-1), hydrogen peroxide (X-2.), time of irradiation (X-3) and microwave power (X-4) were evaluated by factorial design of experiments. Results showed that X-1, X-2, X-3 and X-4 had significant effects on the response followed by the interactions X1X2, X1X3, X2X4 and X1X2X3. The highest degradation of phenolic compounds was found for 500 mg/L copper dose, a power of 340 W, 12 M H2O2 and 8 min irradiation time. FTIR analysis confirmed that microwave degradation of polyphenols by means of the Fenton-like system Cu(II)/H2O2 could be an efficient solution for the treatment of olive mill wastewater.
