| Outline of Final Research Achievements |
As a means of elimination of particles from water, there are forced filtration and addition of flocculant, etc., however, a more environmentally-friendly method has been desired. This researcher has revealed "electrically-settling effect" so far. In the flow state, the effect was observed when the field strength equals to or larger than 0.3 V/mm was applied to the suspension. The magnitude of the effect increased as the flow rate decreased. In order to maximize the effect, it has been clarified that the optimized pathway of flow in the experimental cell is very important.
