Sažetak
Olive oil production generates large amounts of solid and liquid wastes, particularly in the Mediterranean countries. Treatment of these wastes is obligatory in EU, but treatment methods are not clearly defined due to the complexity of their composition. The olive pomace leachate is one of the generated wastes and this paper examines its simulated production and treatment. Leaching of olive pomace is a fast process due to the high content of soluble compounds and the obtained acidic leachate has very high Chemical oxygen demand (COD) and Biological Oxygen demand (BOD 5 ) values. The treatment with aeration and flocculation decreases COD for 58.41% at the optimal flocculant concentration of 10 mmol/L. The addition of active carbon decreases the COD value down to 495 mg/L, which is a value suitable for the discharge into sewage systems. Aeration and sorption onto active carbon can be recommended as methods for the treatment of the olive pomace leachate.
