Abstract

An electric field is applied to a coalescer type filter element in which the mesh size decreases in a step-like manner toward its outside. A subject liquid is passed through the filter from its inside to outside. A primary processed liquid discharged from the filter is introduced into an oil-water separating space provided outside the filter which space has an elongated path and to which space an electric field is applied. While the primary processed liquid passes through the oil-water separating space, rise of separated oil and fall of separated water are facilitated.
