Question

The exhaust from a thermal power plant if passed through an electrostatic precipitator removes

• A. Particulate matter up to 10 micrometres
• B. Sulphur dioxide
• C. Carbon dioxide
• D. Particulate matter which is swept away by water flowing in the opposite direction

Answer 1

The correct option is A Particulate matter up to 10 micrometres

Particulate matter upto 10 micrometres
An electrostatic precipitator removes particulate matter up to 10 micrometres when industrial exhausts are passed through it.

An electrostatic precipitator is the most efficient device to remove fine particulate pollutants.

Electrostatic precipitator is a device used to remove the particulate matter released from the thermal power plant in which the electrode wires maintained at a high voltage create a corona of electrons giving the particles a negative charge.

These negatively charged particles are then attracted to the collecting plate grounded in the Earth.

Final answer
(C) Particulate matter up to 10 micrometres
