Abstract
Method and means for separating emulsified and entrained oils from water, machine coolants, and substantially any other liquid comprising initially directing a flow stream into an inlet trap for removing relatively large particles from the flow stream, passing the flow stream through a centrifuge for removing substantially all of the entrained solids in the flow stream, moving the flow stream through a de-emulsifier for coalescing of the emulsified oil into droplets sufficiently large for processing in a separator and for filtering any remaining solids from the flow stream, providing a backwash action from the de-emulsifier for recycling of said finally removed solids through the centrifuge, passing the flow stream through a separator for separation of the oil from the other liquid components of the flow stream whereby the separated oil and clean effluent may be removed from the system. The de-emulsifier comprises a chamber containing a bulk dense granular material, preferably water wettable, and the flow stream is directed into the chamber in a downflowing manner through the granular material for mechanically breaking the emulsion into two phases and separating the solids therefrom. The separator comprises a centrally disposed entrance or spreader tube discharging the flow stream radially outwardly through a body of granular media contained within a cylindrical housing concentrically disposed with respect to the entrance tube. The oil and water, or other liquid, are separated during passage of the flow stream through the granular media whereby the oil percolates upwardly through a water reservoir for collection in a collector, and the water or other liquid flows downwardly by gravity for discharge through a suitable valve.
