Lavender essential oil is one of the most common essentials oils and contributes significantly to the global market as it is used in many fields. Accordingly, the production of it in Turkey has shown remarkable improvement in recent years. Lavender essential oil production is carried out by steam distillation and generates high-strength wastewater. Since the discharge to natural environments without treatment causes various problems, the treatment of this wastewater using various treatment technologies is mandatory. In the present study, the treatability of lavender essential oil production wastewater (LOPW) by Fenton process was investigated. For this purpose, laboratory scale experimental studies were conducted to examine the effects of various basic operational parameters on the performance of Fenton oxidation. Under the optimal conditions (pH = 4.0, H2 O2 = 88 mM, Fe2+ = 54 mM and H2 O2 /Fe2+ molar ratio = 1.62), a chemical oxygen demand (COD) removal efficiency as high as 81% was achieved. Under the same conditions, the highest color removal efficiencies were found to be 92% for Pt-Co, 94% for spectral absorption coefficient. The results suggest that Fenton process can be applied as a pretreatment process to improve COD and color removal from LOPW.
