  • The History of Bottle and Containers – Amphorae and barrels

    Amphorae and barrels From ancient times, amphoras and barrels are the most comonly used containers for transporting water, wine and olive oil. The amphora being porous, has the disadvantage of losing some of its liquids by evaporation. The barrels, meanwhile, give a woody taste to the wine. This taste is certainly appreciated by winemakers, oenologists and sommeliers, on the other hand, they ...

  • Efficiency concept under stochastic consideration of water value in irrigated agricultural land in Crete, Greece

    Water is an increasingly scarce and valuable resource. It is generally accepted that there is a finite supply of water. As economies grow there is an increasing demand for water. The application of water to agricultural lands for irrigation is one of the essential uses of this natural resource in many areas. There is competition among agriculture, industry, and human consumption for the ...

  • Fabrication and application of boron doped diamond BDD electrode in olive mill wastewater treatment in Jordan

    A boron doped diamond (BDD) electrode was employed in an electrochemical reactor to oxidize the phenolic content of Jordanian olive mill wastewater. The BDD anode was fabricated using hot filament chemical vapor deposition on niobium and the morphology of the BDD electrode was characterized using an atomic force microscope. Then, electrolysis batch runs were carried out at laboratory scale to ...

  • Innovative method for recovery and valorization of hydroxytyrosol from olive mill wastewaters

    The nutritional properties of olive oil can be attributed to its oleic acid and phenolic compounds content, acting as natural oxidants to prevent human diseases. In particular, hydroxytyrosol has an anti-inflammatory action similar to omega 3 fatty acids from fish oil. The olive oil production was conducted by two extraction procedures: first, a two-phase extraction giving extra-virgin olive ...

  • Comparative study of isotherm parameters of lead biosorption by two wastes of olive-oil production

    Batch isotherm studies were carried out on a laboratory scale: (i) to investigate the effectiveness to remove lead of two wastes (olive stone (OS) and olive tree pruning (OTP)), untreated and chemically treated; and (ii) to examine the applicability of various adsorption isotherms to fit the experimental data. Results from tests were analyzed using seven equilibrium isotherm correlations ...

  • Review: Effects of olive mill wastewater application on soil properties and plants growth

    Comparative effects of untreated olive mill wastewater (UOMW), treated olive mill wastewater (TOMW) and bioaugmented olive mill wastewater (BOMW) on soil properties, on seeds germination and on plants growth were investigated. The water holding capacity, the salinity, the organic carbon content, humus, total nitrogen, phosphate and potassium increased when the spread amounts of UOMW (50, 100 and ...

  • Chemical and biological properties of a sandy loam soil amended with olive mill waste, solid or liquid form, in vitro

    The profitable use of the large amounts of olive oil mill wastes produced in Greece, as source of soil organic matter, might be probably beneficial to soil microorganism activity. A high rate of organic matter biodegradation was observed in soil samples amended with the liquid form of olive mill wastewater, whereas the vice versa results were obtained with the solid form. When the soil ...

  • Case study - Olive mill waste water treatment

    The production of olive oil generates two kind of waste waters: RINSING WATERS: the quantity is subject to change. It can be re-circulated, after the settling to remove the solids, or discharged directly. SLUDGE: vegetation water with additional water, whose quantity is subject to change. In case of traditional oil mills, the hot additional water flows to the inlet of the centrifuge. Part ...

  • Olive Processing

    Problem: The aerated ponds were producing a foul odor & the chloride content of the aquifer was increasing to a level endangering the water quality. Solution: A Hydrocal CAF system is installed to treat the pit water only. This stream, which aligns the olives to be pitted, is highly contaminated with oil, grease, and ruptured olive tissue. The separate ...

  • Argan oil: Too much of a good thing?

    Most people have heard of the health benefits of using olive oil instead of butter or other saturated animal fats. The monounsaturated fats in olive oil have been shown to reduce levels of harmful cholesterol, and as a result nutrition experts have touted it and other aspects of the Mediterranean Diet as heart healthy. But olive oil ...

  • The water footprint as an indicator for managing water resources: the case of Italian olive oil

    Researchers, politicians and decision-makers continue to search for a recipe for sustainable economic growth. International interest is growing in the use of material indicators for evaluating the impact of human activities on natural systems. Water footprinting is becoming a popular way of understanding the total water input used to produce goods and services to help managers and policy makers ...

  • Fertilizer NPK from human urine and olive oil mill wastewaters

    The objective of this work was to determine how some wastewater acids could be used to prevent the decomposition of urea into ammonia during storage. The effect of storing human urine with olive oil mill wastewaters (OOMW) or water bubbled with CO2 (BW), was studied. Moreover, the application of two levels of urine dissolved in water OOMW, has been studied in relation to the properties of two ...

  • Exergoeconomic analysis of an olive oil refining plant

    This study deals with evaluating the performance of an olive oil refinery plant installed in Izmir, Turkey, using Exergy, Cost, Energy and Mass (EXCEM) method, which is based on the real operational data and costs of the equipments. The most efficient equipment is obtained to be the shell and tube type heat exchanger with an exergy efficiency value of 85.8% at 25°C, ranging from 86.2% to 85% for ...

  • Olive oil Mill Wastewater properties change during infiltration through clay soils

    Olive oil Mill Wastewaters (OMW), are stored in clay basins in the region of Sfax (Tunisia). Field permeability measurements showed that the clay is not completely impermeable and its structure can be modified by the infiltration of OMW. Analysis of chemical composition of soil revealed the presence of phenolic compounds resulting from the percolation of OMW. An infiltration filled with clay and ...
