Electrostatic precipitators (ESP) are devices used for controlling and removing particulate matter (PM) from industrial exhaust gases. The following points shows the usage

1. Air pollution control: ESPs are commonly used in industries such as power generation, cement manufacturing, metal processing, and chemical production to control air pollution and reduce emissions of particulate matter.

2. Product recovery: ESPs can also be used to recover valuable products such as sulphuric acid mist and metal fumes from exhaust gases.

3. Indoor air quality: ESPs can be used to improve indoor air quality by removing particulate matter from sources such as tobacco smoke and cooking fumes.
