Which of the following is a commonly used particulate matter control technology?

  1. Electrostatic Precipitator

  2. Fabric Filter

  3. Wet Scrubber

  4. All of the above


Correct Option: D
Explanation:

Electrostatic Precipitators, Fabric Filters, and Wet Scrubbers are widely used technologies for controlling particulate matter emissions from various industrial and combustion sources.

What is the primary mechanism of pollutant removal in a fabric filter?

  1. Inertial Impaction

  2. Diffusion

  3. Electrostatic Attraction

  4. Gravitational Settling


Correct Option: B
Explanation:

In a fabric filter, particulate matter is primarily removed through diffusion, where particles collide with the fibers of the filter media due to Brownian motion.

Which type of air pollution control technology is commonly used to remove gaseous pollutants such as sulfur dioxide and nitrogen oxides?

  1. Catalytic Converter

  2. Selective Catalytic Reduction (SCR)

  3. Activated Carbon Adsorption

  4. Biofiltration


Correct Option: B
Explanation:

Selective Catalytic Reduction (SCR) is a widely used technology for controlling gaseous pollutants like sulfur dioxide and nitrogen oxides by converting them into harmless compounds using a catalyst.

What is the primary mechanism of pollutant removal in an activated carbon adsorption system?

  1. Chemical Reaction

  2. Physical Adsorption

  3. Biological Degradation

  4. Electrostatic Precipitation


Correct Option: B
Explanation:

Activated carbon adsorption systems remove pollutants through physical adsorption, where pollutant molecules are attracted and held onto the surface of activated carbon particles.

Which of the following is an emerging technology for air pollution control?

  1. Membrane Filtration

  2. Plasma-Based Technologies

  3. Photocatalytic Oxidation

  4. All of the above


Correct Option: D
Explanation:
