Olive mill wastewater (OMW) was treated by photocatalysis using TiO2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached 22%, 57% and 94%, respectively. The differences between these three values indicate the persistence of colourless, non-phenolic compounds. Appli...

The ability of lipolytic yeasts to grow on olive mill wastewater (OMW)-based medium and to produce high-value compounds while degrading this waste, was tested. OMW collected from three-phase olive mills from the North region of Portugal were characterized and used. OMW with COD ranging from 100 g L(-1) to 200 g L(-1) were supplemented with yeast extract and ammonium chloride. Studies of OMW con...

A new nanophotocatalysts series of M2Zr2O7 (M = Mn, Cu, and Fe) doped Fe2Zr2O7 systems were prepared via sol-gel using the pechini method, characterized, tested in photocatalytic degradation olive mill wastewater (OMW). The materials was evaluated by measuring total phenolic compounds (TPCs) Folin-Ciocalteu method for variable pH under a commercial LED lamp (45 W). removal TPCs measured at diff...

The objective of this study is to valorize two waste products which, until now, caused major problems concerning their management and impacts on the environment health. This concerns sludge wastewater treatment station city Fez-Morocco olive mill wastewater, which are produced, respectively, in quantities around 51,100 t/year 514,350 m3/year, by pyrolysis for production biochar. obtained biocha...

Olive mill wastewater (OMW) characteristics make it a suitable resource to be used as a microbial culture media to produce value-added compounds, such as enzymes. In this work, the ability of the novel species Aspergillus ibericus to discolor OMW and produce lipase was studied. An initial screening on plates containing an OMW-based agar medium and an emulsified olive oil/rhodamine-B agar medium...

Olive, as a fruit, cannot be consumed directly due to the oleuropein substance it contains and needs to be processed into either table olives or olive oil through various production systems. Th e process of olive oil extraction results in olive oil as the main product, and two by-products, with olive pomace being one and brown-coloured Olive Mill Wastewater (OMWW) as the other. OMWW has no dire...
