Electrostatic precipitator is widely used in industries for removing dust and gases from polluted air. This device has electrode wires kept at several thousand volts that releases electrons by making a corona. Dust particles get a net negative charge by attaching to these electrons. The collecting plates are grounded and attract the charged dust particles.

Scrubber is an electrostatic precipitator used for cleaning dirty air by capturing the gases like SO2 and other oxides.
