A SEFILTRA Ozone Generator, manufactured in Madrid, Spain, characterized by an air flow of 2 dm 3 /min), ozone concentration of 9,50 mg/dm 3 , an O3 production of 19 mg/min and %weight of 0,8. The contamination indicating parameters as Color, Turbidity, Total Suspended Solids, Chemical Oxygen Demand, Biochemical Oxygen Demand and, Fats and oils, showed satisfactory oxidative levels, with BOD5 and Fats and oils being the most oxidized within 50 minutes of reaction time. All contamination indicators were oxidized by ozone, according to second degree polynomial behavior, with correlation coefficients above 0,98.
