Question

Particulate and gaseous pollutants along with harmless gases are released from the thermal power plants. Name the most widely used device of removing particulate pollutants from the air.

• A. Electrostatic precipitator
• B. Fabric filters
• C. Cyclone separators
• D. None of the above

Answer 1

The correct option is A Electrostatic precipitator

An electrostatic precipitator is widely used to eliminate particulate and gaseous pollutants from the air with the help of a high-voltage electrostatic charge. Thermal power plants release various harmful gases and particulate matter in the environment such as sulfur dioxide, carbon dioxide, nitrogen oxides, and other harmful emissions. Electrostatic precipitators are known to be very effective in removing the harmful chemicals present in the emissions. They are the best device for controlling air pollution.

So, the correct answer is 'Electrostatic precipitator'.
