In this work, the resistances-in-series plus critical flux models are used as a simple but efficient tool inorder to describe and predict the dynamic performance of a reverse osmosis membrane process, aimedfor the tertiary treatment of two-phase olive mill wastewater (OMW2ST). To overcome the uncertaintyof fouling, engineers overdesign the membrane plants by using wide safety margins that trigger the costssensibly. One approach to answer the investor’s need to trust membrane technology is to guarantee thatfouling will be strongly inhibited or avoided. Within this context, concentration polarization and foulingcould be accurately addressed by the applied models. Similar concentration polarization and foulingbuild-up rate on the selected membrane was found in the operating pressure range 15–25 bar(1.20 10 1–1.41 10 1 h 1), but increased over 5 times (6.42 10 1 h 1) upon incrementing thetransmembrane pressure up to 35 bar. Moreover, concentration polarization decreased 22.6% and thefouling build-up rate became reduced 45.5% with an increase of the crossflow up to 5.09 m s 1 uponnegligible energy penalty, also avoiding irreversible fouling. Finally, significantly minor fouling (52.5–56.2% reduction) was attained at the lowest temperature, regularly experienced during the olive oilproduction campaign.

The performance of a fixed-bed cation exchange process was examined for final purification of the ironload derived from catalyst usage in the secondary treatment of olive mill wastewater, which led tounacceptable iron levels. Results showed an increase in the pH value up to 4 enhanced the iron ionexchange (IE) efficiency, which decreased upon higher pH. Furthermore, Thomas model provided utmostaccurate dynamic behavior modeling for all inlet concentrations studied (20, 50 and 100 mg L 1). Additionally, up to 100% recovery efficiencies were maintained even after 10 complete cycles. Finally, aneffluent with quality for irrigation reuse was obtained.
