Industrial air pollution has been an environmental concern increasing in the last few years. There are multiple ways to reduce industrial air pollution, and most of them involve technological interventions such as filters or boilers. This blog post will highlight four methods of industrial air pollution control.
Chemical Methods
Most of the air pollution in the industrial process is formed by chemical reactions. For example, when coal is burned, sulfur dioxide is produced. This sulfur dioxide can be reduced by introducing sodium sulfite into the burning coal. The sodium sulfite reacts with the sulfur dioxide to form sodium sulfate and water. This reaction will reduce the amount of sulfur dioxide released into the atmosphere.
Biological Methods
Biological methods of industrial air pollution control are used to remove particulate matter from industrial gases released into the atmosphere. Biological methods are effective because they use microorganisms (like bacteria) to remove particulate matter from gases and convert it into less harmful substances.
Physical Methods
Physical methods are used to remove particulate matter from gases released into the atmosphere through physical processes such as evaporation or condensation. Physical methods vary significantly in efficiency depending on how much particulate matter is present in industrial gas streams, but they often produce large quantities of clean steam.
Filtration Methods
This type of air pollution control involves filtering contaminated air through different filters. The filters are usually constructed using different materials such as activated charcoal, cotton, and paper. The air is then filtered and cleaned in a process known as filtration. This method is the most cost-effective and popular because it is cheap and efficient.
