Who invented the electrostatic precipitator?
Who invented the electrostatic precipitator?
Frederick Gardner Cottrell is considered the inventor of the electrostatic precipitator.
What do electrostatic precipitators remove?
What do electrostatic precipitators remove?
Electrostatic precipitators are designed to remove very fine particles like dust and smoke from gas streams.
How do ESPs differ from wet scrubbers in terms of energy application?
How do ESPs differ from wet scrubbers in terms of energy application?
Unlike wet scrubbers, electrostatic precipitators apply energy directly to the particles being collected, rather than the gas stream.

Study Notes
Electrostatic Precipitator Invention and History
- Frederick Gardner Cottrell is credited with the first invention of the electrostatic precipitator in the early 1900s.
- The theoretical basis for electrostatic precipitators was developed in 1907, establishing the principles that guide their operation today.
Particle Removal
- Electrostatic precipitators effectively remove fine particulate matter, including dust, smoke, and other airborne particles from industrial emissions and flue gases.
Energy Application Comparison
- Unlike wet scrubbers, which use water to capture particles, electrostatic precipitators apply high-voltage electrical fields for particle removal, leading to lower energy consumption and less water usage.
Initial Applications
- The first emissions targeted by Cottrell's electrostatic precipitator were flue gases from coal-fired power plants, showcasing its effectiveness in reducing air pollution.
