हिन्दीGiven below are two statements: Statement I: In a scrubber the exhaust from the thermal plant is passed though the electric wires to charge the dust particles. Statement II: Particulate matter (PM 2.5) cannot 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:
Correct answer · Option 4
Both Statement I and Statement II are incorrect
Explanation
Statement I describes electrostatic precipitator, not a scrubber (scrubber uses water/reagent spray). Statement II is also incorrect because PM 2.5 causes greatest harm and can be removed by electrostatic precipitator, but scrubbers remove gases like SO2.
