Technology using micro bubbles and technology using ozone that are environmentally friendly are attracting attention.We suggest water treatment system, decolorization system of wastewater and oil removal system that use microbubble ozone.
In water treatment, the BOD increased more than the conventional system. Thus, microbubble ozone is effective as water treatment. In decolorizaiton, the chromaticity of waste water showed a lower value than the conventional system when using microbubble ozone. In removal, residual rate has increased when using microbubble ozone. It suggests that microbubble ozone is not effective to removal. It is thought that the chemical property changed due to the oxidation by ozone. As a result, bubbles did not remove oil.
