| Abstract | In the context of the Circular Economy concept, nowadays widely accepted as vital for present and future sustainable production, olive oil industry must be ready to evolve into a whole environmentally respectful process, and this irretrievable includes an adequate and tailored treatment of the effluents that are generated in olive mills, such as current two-phase olive-oil washing wastewater (OOWW). The treatment together with antioxidant fraction recovery by microfiltration (MF) is proposed in this research. In particular, the key operating input factors of MF for the treatment and valorization of OOWW were analyzed and modelled by the boundary flux theory. This permitted to achieve the prediction, maximization and control of the steady-state permeate flux of the membrane, critical for successful scale up of the process, reaching up to 10,596.5 L/h m(2) under appropriate operating conditions comprising pressure of 8.5 bar, tangential velocity of 4.2 L/min, raw pH0 equal to 5.13 and ambient temperature of 25?. These results highlight a reduction in energy consumption by running the MF process under ambient temperature and raw pH of the effluent, and this is the key to allow the cost-effectiveness of the proposed MF process at industrial scale in the olive mills. |
