Which statement about drift eliminators is true?

• A. They Remove Water Droplets from Air Stream
• B. They Preheat Water
• C. They Remove Dust
• D. They Cool Water via Evaporation

Answer: (A)

Drift eliminators are about capturing droplets that are carried with the air as it leaves the tower. They sit in the upper part of the cooling tower and use baffled or finned surfaces to disrupt the airflow, causing the water droplets to coalesce and fall back into the basin. This significantly reduces water loss and prevents droplets from escaping to the environment.

They don’t preheat water, remove dust, or cool water by evaporation. Preheating would be done by a heat exchanger for that purpose, dust removal is handled by filters or scrubbers, and cooling of water occurs mainly at the fill where evaporation takes place, not at the point of exiting air.
