Electrostatic precipitators use electrostatic forces to separate dust particles from exhaust gases. Particulates can be removed with electrostatic precipitators. Large power station boilers are commonly fitted with electrostatic precipitators. Electrostatic precipitators can be used to sample biological airborne particles or aerosol for analysis. Particulates are removed from the exhaust gases through the use of electrostatic precipitators. Methods of capture include electrostatic precipitators and bag-filters. The fly ash is removed by fabric bag filters in baghouses or electrostatic precipitators. The station used low NOx burners and electrostatic precipitators to reduce its environmental impact. Electrostatic precipitators electrically charge the dirty air as it passes through. Electrostatic precipitators (ESP) are installed to collect fly ash and minimize emissions to the atmosphere. The zinc oxide is collected from the kiln outlet exhaust by filters/electrostatic precipitators/settling chambers etc. Mercury pollution can also be removed by electrostatic precipitators (ESPs). Electrostatic precipitators operate on the same principle as home "Ionic" air purifiers. In order to reduce air pollution the plant's units are equipped with electrostatic precipitators. To control chemical losses and lower the cost of purchased chemicals electrostatic precipitators were added.
