🔍 Key Concepts

• Flow path of brine through a flash-type evaporator (where does concentrated brine ultimately go?) • Function of a brine ejector (what does it remove, and is that water reusable or waste?) • Difference between lines that return relatively clean water to the system vs. lines that discharge waste overboard

💭 Think About

• Look at the location of flange "U" on the rear view and trace what components it is near (valves, overboard connections, return lines). What kind of fluid would realistically be at that point? • Ask yourself: is the discharge from a brine ejector suitable to be returned to any evaporator chamber or feed system, or is it a waste stream that must be led somewhere else? • Compare the labels of the nearby lines: which ones normally carry relatively fresh distillate or feedwater, and which would be expected to carry high‑salinity brine and ejector motive water?

✅ Before You Answer

• Confirm what brine is (high‑salinity concentrate) and whether it should mix with feed water or distillate in normal operation. • Verify which labeled connection in the illustration represents an overboard discharge line versus internal recirculation lines. • Make sure flange "U" is associated with the brine ejector discharge, not with the distillate or feed‑water return paths.
