On the Recent Use of Membrane Technology for Olive Mill Wastewater Purification
Many reclamation treatments as well as integrated processes for the purification of olive mill wastewaters (OMW) have already been proposed and developed but not led to completely satisfactory results, principally due to complexity or cost-ineffectiveness. The olive oil industry in its current status, composed of little and dispersed factories, cannot stand such high costs. Moreover, these trea...
متن کاملOn Operating a Nanofiltration Membrane for Olive Mill Wastewater Purification at Sub- and Super-Boundary Conditions
In the last decades, membrane processes have gained a significant share of the market for wastewater purification. Although the product (i.e., purified water) is not of high added value, these processes are feasible both technically and from an economic point of view, provided the flux is relatively high and that membrane fouling is strongly inhibited. By controlling membrane fouling, the membr...
متن کاملMembrane technology for the separation and the clarification of food additives recovered from olive mill wastewater
In our earlier studies, we proposed a method for the simultaneous recovery of dietary fibers and phenols from olive mill wastewater (OMW) in two different streams: (i) an alcohol insoluble residue (AIR) rich in dietary fibers and (ii) an ethanolic liquid rich in phenols. The ethanolic liquid has been proposed for a direct application in the beverage industry, i.e. as an additive to produce soft...
متن کاملExperimental Design Optimization Of A Reverse Osmosis Membrane For Olive Mill Wastewater Purification After Advanced Oxidation
Although membranes are a mature technology, many aspects are still in development. The main handicap is membrane fouling, investigated by a plethora of researchers in the last years to convince investors to implement membranes as substitutes of a range of unit operations at industrial scale. In the field of wastewater treatments, this is especially problematic, given the low economic value of t...
متن کاملOverview of Membrane Processes for the Recovery of Polyphenols from Olive Mill Wastewater
Problem statement: Olive Mill Wastewater (OMW) is an ambivalent by-product of the olive oil production, which appears in huge amounts every year after the olive-harvest in the production countries, mainly in the Mediterranean region. OMW is characterized by a high organic load and i.a. contains considerable amounts of phytotoxical polyphenols, which cause important environmental problems. Appro...
