The valve labeled "5", in the device shown...

🔍 Key Concepts

• Flow path of oily water through the separator tank module (where does it enter and where does it leave?) • Function of an overboard discharge valve versus an inlet/suction valve in an oily water separator system • Relationship between the pump module and the separator tank module (which side is suction, which is discharge?)

💭 Think About

• Trace the piping starting at the bilge or oily water source, through the pump, and into the separator. Where on the illustration would the separator inlet logically be located? • Look at where the clean water (effluent) would be sent overboard. Is valve 5 closer to the incoming oily mixture or to the treated discharge side? • Compare the location of valve 5 with the pump module components (23, 24, etc.). Would a pump suction valve normally be located up at the top of the separator, or down near the pump suction line?

✅ Before You Answer

• Verify which direction the arrows or piping suggest for the flow into the separator tank versus the flow out to sea. • Check whether valve 5 is directly on the separator tank cover near the inlet nozzle or on the overboard discharge line leading away from the unit. • Confirm that any control or regulating valves for overboard discharge are typically installed on the effluent line after the separator, not right at the separator inlet.
