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...
Lipid composition and antioxidant activity have been carried out in order to valorize the of olive mill wastewater extracts with different solvents (supercritical carbon dioxide, n-hexane, dichloromethane ethanol). The was evaluated using ABTS (2,2′-azino-bis-(3-ethylbenzothiazoline-6-sulfonic acid)) DPPH (2,2-diphenyl-1-picrylhydrazyl) tests. total phenolics flavonoid contents were, also, dete...
Since the interaction between steel reinforcement and concrete directly controls bond strength them, poor performance results in a direct negative effect on existing state of reinforced structures. This is one most important factors affecting concrete. The measured using pull-out test. present paper discusses addition brine olive oil mill wastewaters to mixes. main objective this study determin...
The production of olive oil generates massive quantities of by-product called olive mill wastewater (OMWW). The uncontrolled disposal of OMWW poses serious environmental problems. The OMWW effluent is rich in several polyphenolic compounds. Liquid-liquid extraction of OMWW using ethyl acetate solvent was used to enrich phenolic compounds under investigation. Total phenolic and flavonoid content...
A number of Pseudomonas strains function as inoculants for biocontrol, biofertilization, and phytostimulation, avoiding the use of pesticides and chemical fertilizers. Here, we present a new metabolically versatile plant growth-promoting rhizobacterium, Pseudomonas rhizophila S211, isolated from a pesticide contaminated artichoke field that shows biofertilization, biocontrol and bioremediation ...
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...
olive mill by-products could be composted and applied to olive orchard soils. these practices solve the problem of these wastes disposal and reduce the need for chemical fertilizers. therefore, the aims of this research were: (i) proposing ‘on-farm’ composting process of different olive mill waste mixtures; (ii) investigating the chemical, physical, and microbiological characteristics of produc...
