A compact multi-stage oil-water separator which has application in removing oily contaminants from bilge water in ships is disclosed. The oil-water separator has two toroidal mechanical separation stages (51, 88) on the suction side of a feed pump (27), and a cyclone separation stage (95) and a filtration stage (118, 140) 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.
