Question

Electrostatic precipitators are used to remove these pollutants from the exhaust of thermal plants

• A. Particulates
• B. Harmful gases
• C. Hot vapours
• D. Harmful radiations

Hint:

Electrostatic precipitators = particulate removal. Scrubbers and filters are for gases. Vapours may require condensation; radiation requires shielding. Always match control device to pollutant type.

Answer 1

The Correct Option is A

Electrostatic precipitators remove fine particulate matter from industrial exhaust by imparting an electric charge and collecting particles on charged plates. They do not remove gases, vapours, or radiations.
