Correct answer: A. Electrostatic precipitator
- A. Electrostatic precipitator
- B. Scrubber
- C. Bag filter
- D. Cyclone separator
Explanation
Electrostatic precipitators are highly effective for collecting fine particulate matter because electrically charged particles migrate to oppositely charged collecting plates. Cyclones are mainly suited to coarser dust, while bag filters and scrubbers have different operating limitations.
