An Electrostatic Precipitator (ESP) is a device used to remove fine particles, such as dust and smoke, from industrial exhaust gases. It works by charging the particles as they pass through an electric field, causing them to be attracted to oppositely charged plates. This process effectively captures pollutants, improving air quality and reducing environmental impact. ESPs are commonly used in industries like power generation, cement, and steel manufacturing. They are efficient and can handle large volumes of gas, making them an essential technology for meeting environmental regulations and promoting cleaner air in urban areas.
