🔍 Key Concepts

• Relationship between pressure and phase change (boiling/evaporation) in freshwater generators • How reverse osmosis membranes work (pressure versus osmotic pressure) • Difference between vacuum/low-pressure distillation units and high-pressure filtration units

💭 Think About

• For each type of freshwater generator, ask yourself: does this design rely on boiling/evaporation or on forcing water through a barrier? • Which process needs a vacuum or low pressure to make water boil at a lower temperature, and which needs high pressure to overcome natural osmotic forces? • Think about which units are normally installed on the low-pressure side of the system and which ones use high-pressure pumps as a key component.

✅ Before You Answer

• Identify which option uses a membrane and must operate at a pressure higher than the natural osmotic pressure of seawater. • Eliminate any options that typically operate under vacuum or reduced pressure to promote flashing/evaporation. • Recall that "flash" or evaporator-type units usually involve heating plus vacuum, not high positive pressure.
