🔍 Key Concepts

• MARPOL pollution limits for oil content in discharged water (15 ppm) • How this type of gravity/coalescer oily-water separator in the illustration actually separates oil from water • What detergents/surfactants do to the interface between oil and water

💭 Think About

• Looking at the separator tank module in the illustration, what does the internal packing or coalescer rely on in order to let clean water pass and oil be removed? • How would adding a substance that breaks surface tension and lets oil mix more easily with water affect a device that counts on oil droplets rising and coalescing? • Which option describes something that would prevent the separator from meeting discharge standards, rather than something dramatic but unlikely like an explosion?

✅ Before You Answer

• Verify which choice explains an effect that would interfere with the separation process shown in the illustration, especially around the coalescer media. • Rule out choices that talk about damage or explosions – does the drawing or typical operation of an OWS suggest those are realistic? • Choose the option that best connects detergents with forming a stable oil‑water mixture that a standard OWS cannot effectively process.
