In this work, the benefit of using photocatalysis as a pretreatment step for a subsequent olive millwastewater (OMW) treatment process by membranes will be discussed. Membrane processes appear to be suitable to purify aqueous wastewater streams polluted by organicmatter such as OMW, but suffer severe fouling. In order to avoid fouling, the use of operating conditionsbelow the boundary flux is suggested. The problem is that in many cases, boundary flux values areextremely low, making the process economically not feasible. In order to overcome this limitation,pretreatment steps are necessary to increase boundary flux values accordingly. Photocatalysis appears tobe capable to achieve these requirements: on one hand, the process is capable to reduce the organic loadof the feedstock and on the other hand, particle size distributions of the suspended organic matter arechanged. Both principles are known in literature to lead to boundary flux value changes. In this paper the authors report the obtained results of the experimental work concerningphotocatalysis and membrane performances.

The final purification of two-phase olive mill wastewater (OMW-2) by ion exchange (IE) was addressed. This pollutant effluent was previously subjected to Pseudo-Fenton secondary treatment. Consequently,OMW-2 presented high concentrations of chloride, sodium, phenols and iron, which hinder its discharge. Experimental design was used to optimize the IE process. Around 88% removal efficiencies of thesepollutants were achieved when initial pH, temperature and flow rate were 5.1, 26.8 8C and 12.1 L h 1,respectively. Finally, 28 L treated water could be accomplished in continuous mode under optimalconditions, complying with standards for reuse in the olive oil production process.
