A compact multi-stage oil-water separator has application in removing oily contaminants from bilge water in ships. The oil-water separator has a final stage in which the flow of fluid is repeatedly reversed. the separator preferably has two toroidal mechanical separation stages on the suction side of a feed pump, and a cyclone separation stage and a filtration stage on the output side of the pump. The cyclone separation and filtration stages are located inside the mechanical separation stages for compactness. The oil-water separator has built-in fail-safe operation to prevent the accidental discharge of water in the case of contaminated sensors. The oil-water separator has a novel final stage that avoids the need for standard coalescing filters. |
