“…The present work presents a techno-economic analysis of the OMW treatment using membranes filtration. The idea of using membrane technology is presented by authors [11] in a previous work in which a new cost-effective system for complete exploitation of OMW is suggested, offering a viable solution to the problem of OMW disposal. A pilot plant was designed, constructed and installed in a typical olive mill, where OMW quantities were treated at larger volumes.…”

“…These methods were investigated in previous work [10,11] through a systematic parametric study changing accordingly the operational parameters, such as temperature, pressure, ionic strength and initial pH of different source of OMW, size of membranes (pore diameter), etc., in order to lead to a higher separation of toxic fraction from the nutritious one. Different fractions were derived from the whole process: a nutritious fraction as pre-or after-UF concentrate containing the larger components of the solution in terms of molecule size, a toxic fraction as RO concentrate containing the main part of phenols (ecological herbicide), a plant nutritious fraction as RO permeate containing the inorganic salts (fertilizer), and almost pure water for recycling/or irrigation or for free disposal to aqueous acceptors (lakes, rivers or sea).…”

“…Provided that the fixed cost for the installation of OMW treatment systems seems to be inelastic, operational cost reduction may be attained through the exploitation of the waste byproducts. The proposed separation techniques (prefiltration, ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO)) of the OMW treatment using membranes filtration have already presented in a previous work by the authors [10,11]. The idea of using membrane technology is revisited in the present work in which a new costeffective system for complete exploitation of OMW is suggested, offering a viable solution to the problem of OMW disposal.…”

“…Use of the proposed separation techniques produces byproducts that might have high additional benefits. A pilot plant was developed in an olive mill operating in Achaia region (Patras, Greece) during an olive harvesting season [10,11]. A feasibility-exploitation study was performed to estimate if the depreciation of the expensive investment may be done in a short period.…”

The olive oil industry is very important in many Mediterranean countries, both in terms of wealth and tradition. The extraction of olive oil generates huge quantities of high organic wastewaters with toxic constituents that may have a great impact on land and water environments. Series of laboratory experiments, based on the technology of membrane filtration (Ultrafiltration and Nanofiltration and/or Reverse Osmosis), have been carried out for the fractionation of olive mill wastewaters into fractions with nutritive value, phytotoxic action and pure water. Based on these results, a pilot plant of membranes installed in an olive oil mill enterprise for an entire harvesting period and appropriate experiments were performed. The study showed that a fraction of pure water up to 75% can recovered and fractions that contained concentrate nutritious and polyphenol content can be isolated and further exploited in order to reduce the, indeed, high cost of the suggested treatment process.In this study, a techno-economic analysis for the implementation of the suggested method for the Region of Western Greece is presented. The present study took into account the fixed and the operational costs of the equipment, the costs for the infrastructure and land, the costs for the maintenance, etc., considering the treatment of 50,000 tones per harvesting period in the Region of Western Greece. The study showed that the establishment of one central treatment manufacture could reduce the uncontrolled disposal of OMW and their final discharging in the aqueous receptors. The exploitation of the nutritious content of the fractions as manure in fertilizers together with the polyphenol content that can be used as components of ecological herbicides can depreciate the total cost in a very short period of 1.5 years.
