1. How do you reduce the amount of pollutants entering the atmosphere?
Conserve energy!!
Energy Efficient appliances/vehicles

4. Reducing Emissions from Power Plants & Industry
Traditional Methods
1. Move factory to remote location
2. Build taller smokestack so wind blows
pollution elsewhere

5. Some Common Particle Emission Control Devices
1. Electrostatic Precipitator – used to remove particulate emissions by treating the air with an electrical charge to capture the charged suspended particles in the gas flow.

6. 2. Wet Scrubbers –
uses water to dissolve soluble pollutants. The wet scrubber is one of the options that removes SOx.

7. 3. Baghouse filters –
the best option for removal of more hazardous fine particles

8. Cyclone separator–
a method of removing particulates from an air, gas or liquid stream through vortex separation
It is important to note that ALL of the emission control devices produce waste that must be disposed of safely.

9. Reducing Emissions from Vehicles
Catalytic Converter– uses a series of oxidation-reduction (redox) reactions to convert CO and NOX to less harmful products. CO is converted to CO2 and NOX is converted to N2 and O2

10. 2. CAFE (Corporate average fuel economy) standards– Regulations, first enacted 1975, to improve the average fuel economy of cars and light trucks (trucks, vans and sport utility vehicles) produced for sale in the United States.
