Effect of pretreatment by catalytic wet air oxidation on the production of methane by anaerobic digestion from olive mill wastewaters
The production of olive oil in Mediterranean countries generates annually a great volume of olive mill wastewaters (OMW), about 30 millions of m3 1, which content high concentration in organic compounds and have antibacterial and phytotoxic properties. Catalytic wet air oxidation (CWAO) of p-hydroxybenzoic acid as model compound and real OMWs was studied in the presence of supported ruthenium and platinum catalysts at 140-190℃ and 5070 bar total air pressure. These catalysts showed high efficiency for the reduction of total organic carbon (TOC) and phenolic content. Treated OMW showed higher methane accumulation in comparison with untreated OMW in the same experimental conditions of the anaerobic digestion.
