Treatment of Olive Mill Effluent Wastewater Using Some Advanced Processes and Reuse of the Treated Wastewater

Abstract

DT Sponza and Y Biyik

In this study it was aimed to treat the Olive mill effluent wastewater using different sequential treatment processes namely anaerobic and aerobic biological processes, sonication and photo degradation with Nano SiO2 under sun ligth power. The maximum total COD yields were 60 % and 66 % in the anaerobic and aerobic reactor, respectively, while the total COD yield in the sequential biologic reactor was 86 %.The maximum COD yields in the sonicator was 53 % after 45 min retention time. No removal of COD was observed via photolysis and adsorption. The maximum photo catalytic removal of COD was 40 % at a nano SO2 concentration of 0,5 mg/l after 10-60 min. After RO the COD yield was approximately 100% while to yields of total phenol, TN, TP, dissolved COD and DSS were 96.6%, 99.3%, 99.98%, and 99.97%, respectively. The cost to treat 1 m3 of OMW was 1.033 €. The effluent of RO can be used as irrigation water.
