عنوان انگلیسی: Aerobic biological treatment of olive mill wastewater by olive pulp bacteria چکیده انگلیسی: Abstract: The capability of olive fruit bacteria to remove chemical oxygen demand (COD) and phenolic compounds from olive mill wastewater (OMW) using flasks and packed bed reactors was tested. Batch aerobic experiments were performed in flask reactors, with OMW at different dilutions (20%, 50%, and 100%). The maximum phenolic and dissolved COD removal reached up to 82–90% for the dilutions of 20%, 50%, and 100%, in 11, 23, and 30 days, respectively. Experiments were also conducted in a bench and a pilot-scale packed bed reactor, operated in the laboratory and at an olive mill, respectively. At 28 1C the maximum phenolic and dissolved COD removal, recorded at the bench-scale reactor, reached about 60% and 70%,
