Measuring Zetapotential of Microbubbles in DAF
- 발행 : 1998.09.15
초록
Dissolved Air flotation (DAF) has become increasingly important in the field of drinking water treatment, however, the research to investigate the mechanism of collision between bubble and particle has been limited. The electrostatic repulsion forces between them are critical to collide with each other. Zetapotential of bubble and particle show their electrostatic condition. In this research, a setup to measure the zetapotential of rising microbubble is made using electrophoresis method and measured ZP of bubble in our Lab. The results show the effect of pH on zetapotential of bubble. The findings from this research are compared with other results. It will he helpful to understand and explain the mechanism of collisions between bubble and particle on different conditions of bubble charge in DAF process.
