Electrostatic Precipitators
Time to Read: 1m 55s
Electrostatic precipitators, or ESPs, are electronic filtration devices designed to remove fine particulates from a gas flow via an induced electrostatic charge (hence the name). These devices can remove dust, smoke, and other microscopic pollutants, and are generally used to treat gas flows used in industrial processing, or exhaust gases produced by such processing. The first ESP installed in the U.S., Gravesend Bay Municipal Incineration Plant, Brooklyn, NY (May 1973)
