Which component handles oil and water separation in the oily waste system?

• A. Purifier Bowl
• B. Coalescer
• C. Strainer
• D. Oil/Water Separator (OWS)

Answer: (D)

Oil and water separation in the oily waste system is done by the Oil/Water Separator. This unit is built to treat bilge water by letting the denser water flow down while oil droplets, being lighter, rise to the top. Inside the separator, baffles and settling zones give solids a chance to drop out and allow oil droplets to coalesce into larger drops, making the separation more efficient. The cleaner water exits for discharge (meeting regulatory limits), and the separated oil is directed to its own drain or storage. A purifier bowl is for cleaning fuel oil, not bilge water, so it doesn’t perform this separation. A strainer just filters solids and doesn’t remove oil from water. A coalescer helps the separation by merging small oil droplets, but it’s part of the overall separator system rather than the standalone device that handles the separation. So the component designed for separating oil from water in the oily waste system is the Oil/Water Separator.
