- AIn electrostatic precipitator, the particulates are made to acquire positive charge which are then attracted b
- BGravity settling chamber removes larger particles from the air.
- CCyclone collector removes fine particls in the diameter range 5-20 microns.
- DWet scrubbers are used to wash away all types of particulates.
Correct answer
A. In electrostatic precipitator, the particulates are made to acquire positive charge which are then attracted b
