Use and treatment of olive mill wastewater: current situation and prospects in Spain

摘要: The characteristics of olive mill wastewater are set out the viewpoint their pollutant capacity and problems arising from tipping in olive-growing areas. national administration's solutions for preventing pollutions surface waters also stated. Special detail is given to action taken within a research development program financed by Spanish Government EEC through Commission MEDSPA 89 technical-economic evaluation different systems eliminating treating wastewater, order determine feasibility introduction at industrial level. At same time currently under described: - Intensification natural evaporation stored ponds (two systems). - Physical processes using forced eliminate followed aerobic biological or ultrafiltration inverse osmosis final treatment condensate Application physico-chemical greater part organic components wastewaters use clarified fraction (three Biological process complete successive application processes: bioconversion, biomethanisation, treatment, treatment. Treatment yields 99,6% achieved, obtaining by-products commercial interest (one system).
