Excess brine accumulated in the distiller, shown in the illustration, is removed during normal operation by __________. Illustration MO-0111

Correct Answer: Option D — the continuous action of ejector "22"

Ejector 22 functions as a brine pump by utilizing the venturi effect to continuously remove concentrated brine from the distiller shell. This constant extraction is critical to maintain the required salinity levels and prevent scale formation on the heating surfaces, which would otherwise degrade the unit's thermal efficiency.
