Abstract
The present invention is conceived to provide methods for efficiently separating two liquids different in sp. gr. which are in a mixed state and apparatuses for implementing them. The present invention devised an arrangement such that between an outer cylindrical electrode doubled as an apparatus container and an inner cylindrical electrode concentrically disposed relative to said outer cylindrical electrode and set to the equal potential to that of the outer cylindrical electrode, a charging electrode is provided concentrically thereto, thereby defining not only between the aforementioned electrodes mixture liquid passage spaces for letting the mixture of two liquids flow upwardly, but a separated liquid collecting space above said mixture liquid passage spaces, and that inside the inner cylindrical electrode, there is provided a space for letting the liquid to be separated flow down which is designed to guide downwardly the liquid to be separated left after removal of the impurity liquid, with a voltage high enough to neutralize the zeta potential of impurity liquid particles in the mixture applied between the aforementioned electrodes, respectively. In this way, not only the impurity liquid particles in the mixture are got cohere together into coarse particles by dint of their intermolecular attraction, but the separated liquid which has floated up or settled down, according to the sp. gr. difference between the mixture and the coarse particles, is collected and, then, discharged.
