Answer: 4. Electrostatic Precipitator

An electrostatic precipitator removes particulate matter from the exhaust of thermal power plants.

Its electrode wires carry thousands of volts and charge the dust particles. The charged particles stick to the oppositely charged collecting plates, and up to about 99% of particles are removed. A catalytic converter treats gases like CO and NOx in vehicles, STP treats sewage, and an incinerator burns waste.
