An Electrostatic Precipitator (ESP) is a highly effective air pollution control device used to remove particulate matter (PM) such as dust, soot, and smoke from industrial exhaust gases. It operates on the principle of electrostatic forces, where a high-voltage electrical field is applied to charged particles in the flue gas. These particles then move towards oppositely charged collection electrodes, where they are deposited and removed. ESPs are widely used in industries such as cement, power plants, steel, and chemicals to reduce air pollution and ensure compliance with environmental regulations. They offer benefits like high collection efficiency, low operational costs, and minimal maintenance, making them an essential tool for industrial air quality management.
