There has been a continuous increase in the air pollution in recent years.
Environmentally harmful impacts of air emissions include global warming, ozone depletion, acidification or eutrophication of natural ecosystems, and loss of freshwater body biodiversity. On the other hand, the lungs and the respiratory system are seriously impacted by prolonged exposure to air pollution.
In this blog, we will understand some techniques for control of air pollution.
Causes of air pollution
The main causes of air pollution are particulate matter, NOX, SOX, CO2, CO, HC, and other organic and inorganic gases. In order to minimize the harmful impacts of air pollutants on the environment and human health, a variety of air pollution control technologies can be used to reduce air pollution.
Numerous technology applications are used for this.Utilizing air pollution management strategies, dangerous compounds that can impair not only human health but also the environment, are reduced in their gaseous and particle emissions.
Therefore, before a specific control method is adopted and applied to any specific circumstance, a thorough study of the pollutants and their sources is required.
What are the various technologies for air pollution control?
It would be necessary to use more control processes and new cleaning methods, in order to remove the contaminants properly. The choice of control technologies is influenced by engineering, economic, environmental, and pollutant type considerations.
The most recent methods for reducing air pollution are:
Combustion_It is utilized when the contaminants are organic gases or vapors. When organic air pollutants are transformed into less dangerous products carbon dioxide and product water, they are subjected to "flame or catalytic combustion."
Absorption_In this method, contaminated air that contains gaseous pollutants is passed through a scrubber, which is filled with an appropriate liquid absorbent, which traps the air's hazardous gaseous pollutants.
Adsorption_ Using this method, dirty air is passed over porous solid adsorbents that are maintained in an appropriate container. Clean air goes through, while the gaseous contaminants are absorbed at the porous solid's surface.
Methods of reducing particle emissions_ Fabric filters, wet scrubbers, electrostatic precipitators, and some mechanical devices, which operate on the following principles can reduce particulate emissions, which are responsible for air pollution such as dust, soot, ash, etc.
Gravity_ During this procedure, the particle is eliminated after settling down due to the gravitational attraction.
Rapid changes in air flow direction_ It causes particles to separate because of their larger velocity.
Fabric filters_The filters are composed of woven or filled textiles, which act as a porous medium through which the particulate matter is conveyed. While, the gases are released, the particle in the dirty air is filtered and gathered in the fabric filters.
Wet scrubbers_ Using water as a filter, wet scrubbers are used to capture SO2, NH3, and metal emissions.
Electrostatic Precipitators_ When contaminated air with particulate pollutants passes through an electrostatic precipitator, the particles are given an electric charge, which causes the aerosol particles to precipitate on the electrodes.
