The most suitable equipment for removing the fine dust particle (< 1 micron dia.) from air below its dew point will be a/an______________?
Correct answer: B. Electrostatic precipitator
- A. Bag filter
- B. Electrostatic precipitator
- C. Cyclone separator
- D. Wet scrubber
Explanation
Electrostatic precipitators efficiently collect very fine particles, including submicron dust, by electrically charging the particles and attracting them to collecting plates. Cyclones are ineffective for particles below about 1 micron, while bag filters are more prone to blinding under condensing conditions.
