| An apparatus and method for separating water from an oil-and-water mixture includes at least two elongated separator vessels oriented at an incline and connected to one another so that an upwardly flowing oil predominant fluid passes from the first separator vessel to the second separator vessel where further electrostatic separation of water from the oil predominant fluid occurs. Each vessel has an electrode at its upper end preferably connected to a different voltage source. The inlet to each vessel is located relative to the electrode to provide an up flow or a down flow vessel. Additionally, the first vessel may be at a different elevation than the second vessel. An additional vessel may be included with output from the first vessel bypassing the additional vessel, the second vessel, or both. Baffles may be added in the water collection portion of each vessel to reduce turbulence and settling distance. | ||||||

An electric field is applied to a coalescer type filter element (13) 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 (24) 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. |
