Abstract

Abstract This study investigated phenolic compounds (PC), chemical oxygen demand (COD) and total carbon organic total (TOC) removal from olive mill wastewater OMW via activated persulfate oxidation. Persulfate (PS, S 2 O 8 2 −

${\mathrm{S}}_{2}{\mathrm{O}}_{8}^{2-}$

) was activated by thermal and transition metal to form sulfate radical ( S O 4 · −

$\mathrm{S}{\mathrm{O}}_{4}^{{\cdot}-}$

). A mathematical model was developed, and the process variables, namely oxidant dose (0.05 and 0.1 g L−1), type of catalyst (Fe2+, Cu2+), time of treatment (5 and 20 min) and temperature (25 and 45 °C) and their interaction were examined using a full factorial design methodology 24. The results indicated that activation methods are efficient for reduction of PC and COD in OMW. Under conditions maximizing responses, there was a considerable increase in PC, COD and TOC removal (44.73 %, 62.39 % and 95.13 % respectively). The correlation coefficient values of the polynomial model were found to be 90 % (CP removal) and 86 % (COD removal). The predicted values obtained using the response functions agreed well with the experimental data.
