Abstract :
The present work was carried out to test the feasibility of the olive mill wastewater (OMWW) treatment with electrolysis on boron-doped diamond electrode (BDD). The physical-chemical characteristics studies of OMWW show that they are acid, and charged with organic matter. They also contain a large amount of suspended substances, a high concentration of polyphenols and a low degree of biodegradability. In this part, we have studied the influence of the current density and the effect of rotation speed of the electrode on the treatment OMWW. The study shows that, after 30 minutes of an electrolysis treatment, using a current density of 1,29 A/cm2, an OMWW discoloration of approximately 43% occured, with a reduction of the chemical oxygen demand (COD) and of the phenolic compounds, of approximately 60% and 63%, respectively
