Which of the following does not discharge the dust collected as a dry solid?
Correct answer: A. Wet scrubber
- A. Wet scrubber
- B. Electrostatic precipitator
- C. Bag filter
- D. Gravity settling chamber
Explanation
A wet scrubber removes dust by contacting the gas with liquid and therefore produces a wet slurry or sludge. Electrostatic precipitators, bag filters and settling chambers collect particulate matter as dry solids.
