Influence Of Anode Material On The Electrochemical Treatment Of Olive Oil Mill Watewaters

Bensalah Nasr, Bedoui Ahmed, Gadri Abdellatif

In this, the electrochemical treatment of olive oil mill wastewater OMW using different anode materials: iron, stainless steel, boron doped diamond and SnO2 is investigated. Total discoloration of OMW solution is obtained by electro-coagulation using both iron and stainless steel anodes but only 65 % of chemical oxygen demand (COD) content is removed. However, electrochemical oxidation on boron doped diamond leads to the total mineralization of OMW solution. SnO2 anodic oxidation achieves only 40% of COD because of the deactivation of the electrode.
