| Outline of Final Research Achievements |
In this study, the application of nano-bubbled water(NBW) to the washing process of microbial biofilm developed on the surface of stainless steel. There was no significant difference in the removal potential between NBW and tap water. However, NBW generated by sodium hypochlorite solution with 100 ppm active chlorine concentration were effective in BF removal compared with simple sodium hypochlorite solution (250 ppm). It was suggested that the micro-structural property of BF affected on the contact efficiency of active chlorine in NBW with bacterial cells and extra-polysaccharides of BF developed on the material surface.
