Electrostatic Precipitator
Overview	An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases through the unit.
Schematic of Electrostatic precipitator
How Does it Works	The metal grids in the electrostatic precipitator are given a high voltage. Depending on the design, the grids may be positively charged or negatively charged. Dust particles lose electrons if the grids are positively charged Dust particles gain electrons if the grids are negatively charged The charged dust particles then induce a charge on the earthed metal collecting plates and the dust particles are attracted to the plates.
