<p>A purification system for separating phases of a solid/liquid/liquid mixture includes at least one cylindrical filter element including a filter medium (125) for removing solid particulate matter, the filter medium having a bubble point of at least about 200 inches of water, and at least one coalescing element (120) in spaced relationship to the filter medium for coalescing into droplets at first liquid of a solid/liquid/liquid mixture, which first liquid is wholly or partly immiscible in and forms a discontinuous phase with a second continuous phase-forming liquid of the solid/liquid/liquid mixture. The filter element (125) may be detachably mounted adjacent to the coalescer element (120). A method for separating a solid/liquid/liquid mixture into individual phases includes passing the mixture through at least one filter element including a filter medium having a bubble point of at least about 200 inches of water to remove solid particulate matter and thereafter passing the resultant liquid mixture from which solid particulate matter has been removed and in which a first liquid is wholly or partially immiscible in and forms a discontinuous phase with a second continuous phase-forming liquid to coalesce the first liquid into droplets.</p> |
