It is one of challenging problems to remove well dispersed fine particles from dilute slurry, because filtration and evaporation process requires a lot of time and energy. Electrophoresis is known as a method to enhance sedimentation of fine particles with isoelectric point electrophoresis on a substrate. We use the electrophoresis technique for fine particles with higher zeta potential to make concentrated paste of fine particles near electrodes. Concentrated paste near the electrode is falling down during electrophoresis process, finally drops from the electrode. We examined a process to collect the concentrated particle as a paste. In this study, we successfully visualized transport phenomena of fine particles in slurry under electric field using micro X-ray CT.
