Which term is another name for Eduction?

• A. Infusion
• B. Injection
• C. Induction
• D. Infiltration

Answer: (C)

Eduction refers to drawing a secondary liquid into the primary stream, typically using a device like an eductor that creates suction to entrain the additive (often foam concentrate) into the water flow. Induction is the term used for this same idea of bringing a substance into the main stream through suction or entrainment, so it’s the best match. Infusion would imply gradually introducing a liquid, injection implies forcing a liquid in under pressure, and infiltration refers to seepage into materials or spaces—none of these describe the suction-driven mixing used in eduction.
