The equipment that can be used to control particulate air pollution in an industrial unit is/are
- Electrostatic precipitator
- Cyclone separator
- Gravity settler
- Incinerator
The Correct Option is A, B, C
Solution and Explanation
Step 1: Identify equipment for controlling particulate air pollution. Particulate air pollution refers to suspended solid or liquid particles in the air. Common equipment used to control these particles includes:
Electrostatic precipitator: Efficiently removes fine particles by applying an electrostatic charge to the particles and collecting them on oppositely charged plates.
Cyclone separator: Removes larger particulates by using centrifugal forces to separate particles from the air.
Gravity settler: Removes particles by allowing them to settle due to gravity, suitable for larger and heavier particulates.
Incinerator: Used for burning waste but not specifically for controlling particulate matter; it is designed for volume reduction of solid waste.
Step 2: Analyze the options.
(1) Electrostatic precipitator: Correct. Effective for controlling fine particulates.
(2) Cyclone separator: Correct. Used for controlling medium-to-large particulates.
(3) Gravity settler: Correct. Suitable for large particulates in industrial applications.
(4) Incinerator: Incorrect. It is primarily used for waste combustion, not particulate pollution control.
