Gaseous wastes are oxides of carbon, sulphur dioxide, oxides of nitrogen, hydrocarbons, aerosols, carbon monoxide, methane, Green house gases like chlorofluorocarbon (CFC) etc. Due to the increase of factories, industrial areas and the number of vehicles, a large amount of gaseous wastes are coming to the atmosphere.
Management of Gaseous Wastes:
Following methods are used for the management of gas wastes:
1. Settling chambers:
Dust articles are collated.
2. Filters:
It is the method to separate particles from the gas.
3. Electrostatic Method:
In this method, electrostatic forces are used to move the particles to the collection surface. Here waste gas is passed between high voltage discharge electrodes.
4. Absorption:
In this method a mass of waste gases, specially carbon dioxide is transferred to the liquid.
5. Smokeless fuels can be used by industries.
6. Hydrocarbon emissions of vehicles can be controlled by use of unleaded petrol.
7. To control sulphur dioxide concentration in air, low sulphur fuels can be used.
8. More fuel efficient automobiles should be allowed to pass on the roads.
9. Instead of diesel, less polluting fuels like CNG (Compressed Natural Gas) should be used more.
10. Use of scrubbers can remove aerosols of solid-liquid nature from air.
