Özet

Agroindustry factory’s such as the table olive industry etc. that gain importance in the 9 economies of Mediterranean countries. Conventional treatment methods are not effective for 10 treating table olive processing wastewater due to its unique composition. Ultrasound/Ultraviolet 11 light (US/UV) oxidation was used to treat wastewater of table olive industry to improve 12 hydroxyl radicals and enhance organic compound removals. A statistical experimental design 13 was used on table olive processing wastewater to examine the effects of the UV/US oxidation 14 process. The highest removal efficiency for chemical oxygen demand, total organic carbon, 15 color, suspended solids and phenol were obtained as 64%, 52% 60%, 87.5% and 22.3%, 16 respectively. These results were obtained under optimal conditions of 20 minutes reaction time for ultrasound process, intensity of 50 W/cm2 17 , and 20 minutes reaction time for ultraviolet 18 process in the US/UV process. The study also showed that the ultrasound/ultraviolet oxidation 19 process resulted in small reaction time and low chemical requirements. Sludge production and 20 operational cost decreased at best experimental conditions due to small reaction time and low 21 chemical requirement
