Abstract: 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 submerged with OMW at a height of 1.5 m was used to study the composition change of the support as OMW percolates through the clay. Compared to the raw OMW, infiltrated effluent showed a decease of its polluting load.
Keywords: olive oil mills; wastewater storage; permeability; phenolic compounds; soil infiltration; polluting potential; Tunisia; wastewater percolation; environmental pollution; soil contamination.
