ELECTROSTATIC PRECIPITATOR | PPT
An electrostatic precipitator (ESP) uses electrostatic forces to remove particles from gases. It works by charging particles as they pass through a corona, or glow zone, then collecting them on oppositely charged plates. ESPs are highly efficient, able to remove over 99% of particles down to 0.1 μm, while minimally slowing gas flow.
