In the study of air quality, what is the primary function of a Particulate Control System (PCS)?

• To increase the emission of gases

• To filter and remove particulate matter

• To enhance the combustion process

• To measure the temperature of emissions

Which of the following is a common method used in PCS to remove particulates from emissions?

• Electrostatic precipitation

• Thermal expansion

• Chemical reaction

• Magnetic separation

In a PCS, what role does an electrostatic precipitator play?

• It heats the particulates to burn them off

• It uses magnetic fields to attract metal particles

• It charges particles to attract them to plates

• It dissolves particles in a chemical solution

What is a key advantage of using a PCS in industrial settings?

• Increases energy consumption

• Reduces air pollution

• Increases production speed

• Decreases equipment lifespan
