Which of the following statements describes the approximate relation between the feedwater entering the unit shown in the illustration and brine being removed? Illustration MO-0111

Correct Answer: Option A — Seventy-five percent of the feedwater entering the unit is removed as brine.

Marine low-pressure evaporators typically reject approximately 75 percent of the incoming feedwater volume as concentrated brine overboard, maintaining proper salinity levels and preventing excessive scale formation on internal heating surfaces.
