What causes Industrial air pollution?
Industries have contributed significantly to environmental degradation. Indeed, factories have been blamed for as much as two-thirds of the pollution that has contributed to climate change. Not only is the planet's ecosystem at risk as a result of pollution from poisonous and harmful items entering our surroundings, but our own health is also at stake. Large volumes of organic substances such as carbon monoxide, hydrocarbons, and chemicals are released into the atmosphere as a result of industrial processes. The greenhouse effect is caused by a large amount of carbon dioxide in the atmosphere. Because greenhouse gases absorb infrared radiation from the earth's surface, their presence is beneficial to the planet. Excessive amounts of these gases, have been released into the atmosphere, resulting in current climate change. Because of their various physical and chemical properties, molecular weight, and duration in the atmosphere, different greenhouse gases contribute differently to global warming.
Causes of industrial pollution
1. Unprecedented Industrial Development
Unplanned development in most industrial townships degrades the environment with both air and water pollution.
2. Using Out-of-Date Technology
The majority of industries continue to use outdated technologies to produce waste-generating products. Many organizations still use traditional methods to produce high-end items in order to save money and time.
3. Presence of a Large Number of Small Scale Industries
Many small-scale companies and factories that lack sufficient funds and rely on Government assistance to run their day-to-day operations frequently violate environmental standards and emit a significant amount of harmful gases into the atmosphere.
4. Inefficient Waste Disposal
Water contamination and soil degradation are frequently the result of inefficient garbage disposal. Long-term exposure to polluted air and water leads to chronic health issues, making industrial pollution a serious problem. It also degrades the air quality in the surrounding areas, resulting in a variety of respiratory problems.
5. Natural Resource Degradation and Depletion
Industries require a steady supply of fresh raw materials to manufacture their final products. As a result, a variety of raw materials, such as metals, minerals, plants, and oils, are removed from deep below the ground, depleting resources while also harming land and water supplies. Deforestation or clearing of vegetation cover to make space for industrial raw material extraction leaves lands naked or devastated.
What are the equipment used to control air pollution in industries?
Ambient air pollutants have a variety of negative consequences for human health, environment, and structures. Specific pollutants are more toxic and have negative impacts on worker and public health. Because of tighter compliance standards, more enforcement, and rising community pressure, an effective air pollution management system is vital in today's industrial scenario.
The common types of industrial pollution control equipment’s are: air scrubbers, wet scrubbers, mist collectors and electrostatic precipitators. These all employ multiple pollution control techniques.
1. Air scrubber
An air scrubber is a type of air purification equipment that eliminates particulate matter from the air by using wetness or filtering the airstream as it passes through it. An air scrubber's main job is to clean the air after it has been contaminated by harmful fumes, chemicals, gases, and pollutants. Air scrubbers are an important component of any industrial process that produces pollutants or harmful gases. Their use assures that any air leaving a company's facility is free of impurities, dangerous emissions, or pollutants of any kind. Air scrubbers are useful for removing unwanted odours and giving fresh, clean air, in addition to their duty as an air cleaning equipment.
2. Wet scrubbers
Wet scrubbers are efficient equipment for cleaning particles and/or gases from industrial exhaust streams. A Wet Scrubber works by adding a scouring liquid – usually water – into the unclean gas stream. The cleansing liquid collects any particles or gases. Wet Scrubbers are the best air pollution management equipment for collecting both particulate and gas in one system.
3. Mist collector
A mist collector is a device that gathers dust and other contaminants from the factory's air or gas and improves the air quality. They filter particulate matter from the air before releasing it into the atmosphere and are also known as dust collectors. They're frequently employed to collect mists produced by coolants and oil in the air during metalworking.
4. Electrostatic precipitator
By charging particles positively or negatively with electrical energy, an electrostatic precipitator (ESP) removes these particles from a gas stream. The charged particles are then attracted to collector plates with the opposite charge. The collected particles can be removed either as dry material (dry ESPs) or by washing them away from the collection plates with water (wet ESPs). ESPs can achieve collection efficiency of greater than 99 percent.
