THE FILTRATION OF OLIVE-MILL WASTEWATER WITH PUMICE ORES

摘要

In this study, the usage of pumice ores as filtration raw material was investigated to remove phenol and reduce chemical oxygen demand (COD) from olive-mill waste water (OMW). Some properties covering physical, chemical, mineralogical, microscopic and structural characteristics of pumice ores received from Menderes-Izmir were determined. A relationship between these properties and filtration recovery was investigated. The removal of phenol and COD from olive-mill wastewater increased with the use of different Menderes pumice ore samples. P_a sample containing larger pores gave better results than P_b sample. The removal of phenol and COD from OMW increased as the dosages of P_a were raised. The removal from OMW with the use of 30% P_a was 41.49% for phenol and 65.52% for COD.
