| Outline of Final Research Achievements |
In order to remove photoresist using ozone, research on cleaning effect of Venturi tube ozone microbubbles was carried out. It was strongly influenced by flow velocity and ozone water concentration. This system has about 2 to 4 times higher washing rate than existing method.
The atomization of the coagulant and the effect of the turbid water treatment when flowing water, air and coagulant in the Venturi tube was investigated. By passing through the Venturi tube, atomization of the coagulant was realized. Transport of coagulant showed the effect of bubbles generated by the Venturi tube. Furthermore, the possibility that the zeta potential between bubbles, flocculants, and earth and sand acts properly may have an effect on the treatment of turbid water.
