The function of item "7" shown in the illustration is to __________. GS-0153

Correct Answer: Option C — prevent separated oil from mixing with the incoming bilge water

The inlet weir and baffle assembly (7) in an oily-water separator are designed to promote laminar flow and initial gravity separation. By directing the incoming bilge water, the weir prevents turbulence and ensures that separated oil remains isolated from the incoming mixture, facilitating efficient primary separation before reaching the coalescer.
