🔍 Key Concepts

• Purpose of an air ejector in an evaporator-type fresh water generator • Difference between vacuum (evaporation) systems and pressure (membrane) systems for fresh water production • Which types of generators rely on boiling/evaporation under vacuum versus those that force water through a semi‑permeable membrane

💭 Think About

• Which units on the list need a vacuum to let water evaporate at a lower temperature? Those units will need an air ejector to maintain that vacuum. • Which option works by pushing seawater through a membrane using high pressure instead of boiling it? A vacuum (and therefore an air ejector) is not needed there. • Look at the names: which ones clearly sound like distillation/evaporation equipment, and which one sounds like a filtration or membrane process?

✅ Before You Answer

• Identify which choices are evaporator/destillation types (these normally need an air ejector). • Identify which choice is a membrane/filtration type that works on pressure rather than vacuum. • Before picking, ask: "Does this design need vacuum for operation?" If no, then an air ejector is unnecessary.
