Given below are two statements :

Statement I :

In a scrubber the exhaust from the thermal plant is passed through the electric wires to charge the dust particles.

Statement II :

Particulate matter (PM 2.5) can not be removed by scrubber but can be removed by an electrostatic precipitator.

In the light of the above statements, choose the most appropriate answer from the options given below :

1. Statement I is incorrect but Statement II is correct

2. Both Statement I and Statement II are correct

3. Both Statement I and Statement II are incorrect

Best answer

Answer: 1. Statement I is incorrect but Statement II is correct

Key idea: Electric charging of dust belongs to the electrostatic precipitator, not the scrubber.

Statement I: wrong. In an electrostatic precipitator, electrode wires charge dust particles, which are then collected on plates. A scrubber passes the exhaust through water or lime to remove gases such as \(\mathrm{SO_2}\).
Statement II: correct. A scrubber is meant for gases and does not remove very fine PM 2.5, while an electrostatic precipitator removes over 99% of particulates, including fine ones.

Answer: option 1.
