The present research aimed to investigate the ozone dissolution efficiency and to contribute to economic and efficient ozone treatment by introducing a micro/nano bubbles (MNB) ozonation system that is a complement to shortcomings for low ozone dissolution efficiency and high ozone generation costs in the general bubbles(GB) ozonation system being used in water treatment. Also, the present research has another purpose which assess the reuse possibility according to use for the treated wastewater by applying this innovation method. The MNB ozonation system showed 2 times higher ozone transfer efficiency than the GB ozonation system. Also, it is expected that the MNB ozonation system is an efficient one unit water treatment process. Since it could has excellent suspended solid removal capability, excellent oxidation and disinfecting capability due to small size and a strong disinfectant. The flotation and disinfection treatment effects were researched by using the MNB ozonation system. This research explored the possibility of enhancing the reuse water quality standards for human-friendly water for only 60 minutes operation with effluent from a secondary clarifier of the K sewage treatment plant in the MNB ozonation system.
