Characterisation of humic acid maturation by fluorescence spectroscopy and thermal analysis during composting of olive mill waste
Humic acids isolated from different stages of olive mill waste composting were investigated by Elemental analysis, Fluorescence spectroscopy and by Differential Scanning Calorimetry (DSC). The Elemental composition of these humic acids indicates an increase in aromatic structures during the composting. Indeed, the fluorescence results showed an increase in condensed aromatic ring systems. ...

Suitability of Wastes from Olive-Oil Industry for Initial Reclamation of a Pb/Zn Mine Tailing
An incubation experiment was conducted to evaluate the ameliorating role of two organic amendments—olive-mill solid wastes and compost from olive-mill solid wastes- in the ecological reclamation of a lead/Zn-mine tailing collected in southern Spain. Four enzymatic activities (dehydrogenase, β,-glucosidase, urease and phosphatase) and soluble and AB-DTPA extractable Pb and Zn and were ...

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 ...

A technology for the treatment of olive-mill waste water in a continuously fed plant
Abstract A bench-scale pilot plant has been developed for the treatment of olive-mill water. The plant is fed in a continuous mode and implements a primary treatment (sand filtering and irradiation with UV-rays) and a secondary treatment (anoxic and aerobic biological treatment). Satisfactory results were obtained and the treated green water falls under the limits of the Italian legislation. ...

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 of ...

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 ...

Composting of a mixture of orange and cotton Industrial wastes and the influence of adding olivemill Wastewater
The rapid expansion of the agro-industry during recent decades has led to the increasing production of organic wastes. Some such agroindustrial wastes are olive mill wastewater (OMW), the waste from orange juice extraction (OW) and the waste from cotton gins (CW). The OMW resulting from olive oil production contains olive pulp, mucilage, pectin, oil, the vegetable water of the fruit and the water ...

Valorising Agri-Waste – Agriculture produces an unsustainable amount of waste, so how does the bioeconomy let us derive value from it?
For every kilogram of “usable” crop produced in agriculture, between 1 and 2.5 kilograms of residue is also produced. Of course, some of this residue must remain in the field or be used elsewhere on the farm in order to maintain a healthy ecosystem, but that which isn’t used thus is an unavoidable waste. Minimising waste is one of the central tenets of sustainability: the waste ...
