Description
Summary:The olive (Olea europaea) culture represents one of the most important crops in the Mediterranean region, and is widely diffused not only in European countries such as Italy, Spain and Greece, but also in other Mediterranean countries as Tunisia and Morocco. The manufacturing process of olive oil usually yields two waste residues: the exhausted husks and the olive mill waste-waters (OMW). The total production of this latter effluent is more than 30 million m super(3) per year. The high levels of BOD and COD, until concentrations of 100 and 220 kg/m super(3), respectively, make OMW one of the major agent of pollution in Mediterranean region. The waste of processing of 500 m super(3) olives/year has a polluted load equivalent to the urban sewage of a 7000 people town.
