Given below are two statements:
Statement : In a scrubber, the exhaust from the thermal plant is passed through the electric wires to charge the dust particles.
Statement : Particulate matter (PM ) cannot be removed by a 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:
Options
- ABoth Statement and Statement are incorrect
- BStatement is correct but Statement is incorrect
- CStatement is incorrect but Statement is correct
- DBoth Statement and Statement are correct
Correct answer
C. Statement is incorrect but Statement is correct
Step-by-step solution
There are several ways of removing particulate matter from the polluted air.
A scrubber is generally used, can remove gases like sulphur dioxide. In this scrubber, the exhaust is passed through a spray of water or lime.
Electrostatic precipitators can capture fine particles like those that are smaller than 2.5 microns in diameter, which are especially dangerous if released because they can be drawn deep into the lungs and can trigger inflammatory reactions. Scrubber cannot separate these.
