Detailed Solution

In electrostatic precipitators;

The collecting plates are grounded and attract the charged dust particles.
It has electrode wires that are maintained at several thousand volts, which produce a corona that releases electrons (negatively charged).
The velocity of air between the plates must be low enough to allow the dust to fall.

Air is passed through a spray of lime water in scrubbers.
