Air pollution control, refer to the techniques employed to reduce or eliminate the emission of harmful pollutants into the atmosphere. We bring five effective methods to control air pollution:
1. Source Correction Methods
- Substitution of raw materials
- Process Modification
- Modification of Existing Equipment
- Maintenance of Equipment
2. Pollution Control Equipment:
Pollution control equipment’s are generally classified into two types
- Control devices for particulate contaminants.
- Control devices for gaseous contaminants.
Control Devices for Particulate Contaminants:
- Gravitational Settling Chamber
- Cyclone Separators (Reverse flow Cyclone)
- Fabric Filters (Baghouse Filters)
- Electrostatic Precipitators
- Wet Collectors (Scrubbers)
3. Diffusion of Pollutants in Air
4. Vegetation
5. Zoning
