Referring to the illustration, note that the solenoid in line "C" is closed. The check valve in line "E" is open. The separator service pump is running. The check valve in line "G" is closed. Valve "B" is closed. Valve "D" is open. What is the operational status of the oily-water separator unit? Illustration GS-0175
AI Explanation
The correct answer is A) The oily-water separator is in the bilge water separation processing mode with water discharging back to the bilge water holding tank with an oil content greater than 15 ppm.
This is correct because with the solenoid in line C closed, the check valve in line E open, and the separator service pump running, the oily-water separator is actively processing bilge water. However, since the check valve in line G is closed and valve D is open, the processed water is being discharged back to the bilge water holding tank rather than overboard. Additionally, with valve B closed, the system is not discharging the processed water overboard, indicating the oil content is likely greater than 15 ppm, the maximum allowable limit for overboard discharge.
The other options are incorrect because they do not accurately reflect the operational status of the oily-water separator based on the given information.
