These are used to remove suspended particulate matter (SPM ) from air emissions from factories. The SPM present in air emissions is removed by spraying a jet of water on air. Water thus wets the suspended particulate matter present in air and washes them away.
This device is used if the Suspended Particulate Matter (SPM) present in air emissions is in large amount. These are used in thermal power plants. In order to remove SPM, an electric current is passed through it. Because of this, the dust and smoke present in air get charged up and are thus attracted toward the electrodes and are collected.An electrostatic precipitator (ESP) removes particles from a gas stream by using electrical energy to charge particles either positively or negatively. The collected particles may be removed from the collector plates as dry material (dry ESPs), or they may be washed from the plates with water (wet ESPs).
We ourselves can also contribute to prevent the pollution of air and improve our environment.
1. We can plant more and more trees and nurture the ones already present in the neighborhood. Because they are the nature’s lungs and remove harmful gases. You know very well about Van Mahotsav when lakhs of trees are planted in July every year.
2. We should not use bags made from plastics, because they are non-biodegradable. We should use only cloth and jute bags.
3. We should not burn dried leaves, branches of trees, paper and garbage in the open. Instead they can be put in a compost pit rather than burning. Used paper can be recycled.
4. We should save electricity. In the long run, it will amount to burning less fossil fuel.
5. Smoking should be avoided. Government is also trying to discourage people from smoking.
