An Electrostatic Precipitator (ESP) is a device which removes particles from a gas stream. It acomplishes particle separation by use of an electric field.
The fundamental principle is that the particulates are passed through an electric field where they initially receive an electric charge and then as a charged particle are deflected across the field to be collected on an earthed plate. Then the particles on the collection surface are removed to a hopper by rapping the collection surface.
An ESP can theoratically have 100% efficiency which depicts one of the best solution to clean particulated ait pollutants.
