Wastewater from oil mills causes enormous environmental problems due to the very high content of organic matter (COD up to 200.000 mg/l), which excludes state-of-the-art aerobic wastewater treatment. Anaerobic treatment plants are appropriate for this type of highly contaminated wastewater, but are too expensive for small and medium-sized oil mills. Commonly these olive mills treat their wastewater by evaporation of the wastewater in open basins and burning of the remaining solids or deposition in olive plantations. This procedure cannot be further accepted as a provisional solution or even as state of the art. These facts predestine physical/chemical treatment procedures. The aim of the proposed project is the set up of a suitable economical acceptable technology for reducing the organic load of olive mill wastewater by 95% and thus to fill this gap in the environmental technology market. The technology will consist of a combination of chemical (flocculation) and physical (sedimentation and filtration) wastewater treatment procedures.
