ABSTRACT
 The effectiveness of ozone is well established, yet, not applicable in several treatments due to some limitations. This causes existing industry up-to date is still using ozone gas in several treatment due to the difficulty of ozone to dissolve in water and even if dissolved in water, ozone has a relatively short half-life and the concentration is limited to several treatment. Therefore, in this study a novel system was developed to produce ozonated water with higher concentration and longer half-life by increasing the diffusion efficiency of ozone in water. This system utilizes the parameter with combination of high pressure and flow. The efficiency of mass transfer of ozone into water for both bubble diffuser and venturi injection technique were tested and compared in this research. The concentration of ozone water was examined using dissolved ozone analyzer. It was found that the production of ozone water applying venturi injection technique facilitates the production of higher concentration of ozonated water with higher ozone transfer efficiency. Moreover, the efficiency of the developed system is 2 times higher than the conventional method.
