N2 - Cooling towers are used to increase productivity and efficiency in industrial machinery. The formation of corrosion and humid grass inhibits the heat transfer system thus affecting the efficiency level of the cooling tower. This study aims to determine the effect of ozone usage on corrosion and bacteria in a closed cooling tower system. The method used in this study is to inject ozone into the cooling tower basin and conduct water quality testing in the laboratory using AAS, Titrimetric and TPC tests for bacteria. The results obtained from this study show that the use of ozone with a productivity rate of 0.5 g / hour builds up corrosion, as can be seen from the iron content in water that increased from 0,04 mgFe/1 to 0.07 mgFe /1. In addition, sulfate ions increased from 11 mgSO4 2-/1 to 20 mgSO4 2-/1. The number of bacteria decreased from 2x105 CFU/ml to 3x104 CFU/ml.
