The effects of nano-sized metal oxides namely titanium dioxide (TiO2 ), silisium dioxide (SiO2 ) and zinc oxide (ZnO) on the ultrasound of olive mill effluent wastewater (OMW) in Turkey were investigated. 150 min ultrasound alone provided 61%, 50%, 61% and 66% dissolved chemical oxygen demand (CODdis), color, total phenol and total aromatic amines (TAAs) removals, respectively, at 25o C. The maximum TAAs (90%), total phenol (97%), color (94%) and CODdis (97%) removals were obtained with 5 mg/l nano-sized ZnO, 4 mg/l nano-sized TiO2 , 4 mg/l nanosized TiO2 and 4 mg/l nano- sized TiO2 , respectively, throughout ultrasound.
