The effects of nano-sized metal oxides namely titanium dioxide (TiO2), nickel oxide (NiO) and zinc oxide (ZnO) on the ultrasound of olive mill effluent wastewater (OMW) in Izmir, 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 25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 nano-sized TiO2 and 4 mg/L nano-sized TiO2, respectively throughuot ultrasound.

Key words: Nano-sized titanium dioxide, nano-sized nickel oxide, nano-sized zinc oxide, olive mill effluent, ultrasound.
