Anaerobic digestion of olive-mill wastewater (OMW) was carried out in a continuously fed mode bioreactor. The bioreactor was operated at different hydraulic retention times (HRTs), using OMW, either raw or pre-treated with white-rot fungi. Two different kinds of feed were tested in this process, one which was thermally treated and subjected to sedimentation, in order to remove the solids contained and the other without any physicochemical treatment (raw OMW). Thermally pretreated OMW did not allow a stable operation even at an HRT of 30d. Further pretreatment of the OMW with a white-rot fungus for removal of the contained phenolics, allowed a stable operation at an HRT of 30 d. On the other hand, simple dilution of the raw wastewater, without any solids removal, lead to a stable operation at an HRT of 30d and was accompanied by higher production of biogas. The presence of the solids in the OMW proved to be a determining factor for the stability of the process and could be attributed to a possible adsorption on the solids of hydrophobic compounds, such as long-chain fatty acids that are toxic to methanogens.
