Have you ever heard of how industries contribute to poor air quality? If so, it may be because we live in the 21st century, and many people know about industry air pollution and its impact on the environment and human health. Let me ask you a simple question: What comes to mind when you hear the term “industry air pollution”? Here is the basic answer to the above question: Industrial air pollution occurs when dangerous compounds are released into the atmosphere from factories, mining, and transportation. These contaminants can lead to respiratory illnesses, cancers, impaired lung function, and asthma. They can also impact the ecosystem, causing acid rain and climate change.Â
In this article, I will provide information on how small and large-scale industries monitor air quality with Oizom devices and how air quality data can help the State Pollution Control Board (SPCB) analyze the impact of pollution in real-time and take appropriate actions on industries, or authorities can prepare mitigation strategies to improve air quality in industry.
Importance of monitoring Air Quality in Industries
Industrial air pollution is a major issue that affects individual health and the environment. India’s development has accelerated recently, resulting in increased air pollution and declining air quality. The problem is especially significant in developing nations such as India, where rapid industrialization has increased the number of factories and power plants. Not only do industries cause air pollution, but there are other various sources from which air pollution occurs. Let me share some insights about other sources, too!Â
Air pollution, which ranges from smoke over cities to smoke inside the home, is a severe danger to global health. Almost all of the world’s population (99%) is exposed to air pollution, which increases their risk of diseases such as heart disease, stroke, chronic obstructive pulmonary disease, cancer, and pneumonia. This is where government bodies come into effect to protect their citizens’ best interests. Ensuring a safe environment is critical for urban residents.
Industrial operations generate a variety of pollutants into the atmosphere, including particulate matter, sulfur dioxide, nitrogen oxides, and other harmful substances. The effects of industrial air pollution on residents of an industrial township can be severe. Long-term exposure to these contaminants can result in respiratory and cardiovascular problems, as well as cancer. It can also cause impaired lung function, increased frequency of asthma attacks, and other respiratory problems. Furthermore, industrial air pollution can contribute to environmental degradation, such as acid rain and climate change, which can have long-term consequences for human health and the ecosystem.
17 categories of industrial units are required to have OCEMS. These include power plants, aluminum, zinc, and copper plants; cement plants; distilleries; fertilizers, iron and steel plants; oil refineries; petrochemicals; and tanneries. The emissions monitored under the OCEMS regulations include particulate matter (PM), CO (carbon monoxide), NOx (nitrogen oxide), SO2 (sulfur dioxide), and fluoride.
In mid-March 2020, talks in Parliament revealed that there were approximately 3,700 OCEMS deployed in various industrial areas throughout the country. A month earlier, the Union administration informed Parliament that the total number of targeted units was 4,245. Meanwhile, as of October 2020, the country had just 234 continuous air pollution sensors (also known as CAAQMS – Continuous Ambient Air Quality Monitoring Systems); the data from these monitors is used to calculate the AQI or National Air Quality Index.
Let me tell you one fact: A new report by Greenpeace has identified the fossil fuel industry as the biggest source of air pollution across Africa. The report found that Africa is home to some of the world’s worst nitrogen dioxide and sulfur dioxide hotspots, all of which are primarily linked to thermal power plants.
Significance of Air Quality Monitoring System in Industries
Air Quality (AQ) Monitoring Systems are critical in industries to maintain worker health and safety, regulatory compliance, and environmental protection. These devices are crucial for detecting dangerous pollutants and giving real-time data to manage air quality successfully. Here are the following reasons why it is important to have Air Quality Monitors:
- Health & Safety: Industrial processes often release pollutants such as particulate matter, volatile organic compounds (VOCs), and gasses like sulfur dioxide (SO2) and nitrogen oxides (NOx). Continuous exposure to these pollutants can cause respiratory problems, cardiovascular diseases, and other health issues among workers. Air Quality Monitoring Systems help identify and control these pollutants, safeguarding employees’ health.
- Monitor Regulatory Compliance: Air quality sensors and other devices allow you to track emissions from industrial sources such as power plants and industries to ensure they follow government guidelines and alter your outdoor activities accordingly. One of the primary advantages of air quality monitoring is that it allows us to ensure that the air we breathe is safe.
- Environmental Protection: Industries are major sources of air pollution, which harms ecosystems and contributes to climate change. Monitoring emissions allows enterprises to discover sources of pollution and implement strategies to lessen their environmental impact. Air Quality Monitoring Systems provide the data required to create and assess the success of pollution-control programs.
- Monitor Climate Change: Changes in weather patterns, such as increased heat waves and wildfires, can impact air pollution levels. By tracking these changes, air quality monitoring can help identify the influence of climate change on air quality and take steps to mitigate it.
- Support Research and Development: Continuous monitoring of air quality helps record pollution and changes in air quality for a long time. Gathered data on air quality is a unique source of inspiration for the research and development of innovative pollution control systems that have the potential to minimize industrial emissions.
In addition, Air quality monitoring systems help industries achieve their sustainability goals. These systems provide feedback for improving strategies and promoting sustainable habits by tracking pollution trends and policy efficacy. This contributes to improved air quality and serves broader environmental goals, such as lowering greenhouse gas emissions and fostering green urban areas.
Challenges in Industries
Pollution-related difficulties affect industrial operations, regulatory compliance, and public perception. Addressing these difficulties is crucial for long-term industrial growth and environmental sustainability. These are some of the following challenges in industries:
- Industrial Pollution: Activity within or close to city limits contributes significantly to air and water pollution. While the city’s development strives to boost economic growth, controlling industrial emissions remains difficult. Implementing stringent regulatory frameworks and introducing cleaner technologies in companies are critical steps toward minimizing this form of pollution.
- Data Management: To effectively control pollution in industries, huge amounts of environmental data must be collected for air quality, analyzed, and managed. Ensuring this data’s accuracy, security, and efficiency pose technological and administrative issues.
- Higher cost of FRM/FEM: You all might be aware of traditional reference grade monitors FRM/FEM. How does it work? And what are the pros of it? Let me share with you what are the cons of FRM/FEM: Traditional FRM and FEM monitoring equipment is expensive, typically costing between $15,000 to $40,000 per monitor. Properly running the instrumentation sometimes necessitates a temperature-controlled environment, and routine calibration and maintenance necessitate specialized experts, resulting in even higher operating costs; the annual cost to maintain a FRM can frequently exceed the significant purchase cost.

How Oizom devices’ data is pushed to CPCB
Regulatory bodies such as the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) are pivotal in setting guidelines to monitor and control emissions. The government of India has recognized the problem and has come up with a solution for air pollution. For a better understanding, refer to this press release.Â
Here’s an example of how Oizom devices push data to the CPCB: Imagine an industry monitoring air quality, and they use Oizom devices to collect data. Data is sent to state pollution control boards via authorized vendors or partners of SPCB using Modbus or API integration. The data is transferred to the pollution control board authorities from the Oizom devices’ hardware. It can monitor real-time air quality data, and no data manipulation can be done. Let me walk you through this process to clarify how it all works.
Our client, Adani Power Maharashtra Limited, is the largest coal-based Thermal Power Plant which is located in the state of Maharashtra, India. The plant has a capacity to generate 3300 MW power through its 5 units of 660 MW capacity. Thermal power plants often have high levels of suspended particles and hazardous gasses, such as SO2, NO2, etc. Because the thermal power plant is close to the community, it was critical for the company to monitor suspended PM2.5, PM10, SO2, and other gasses. It was also in their interest to reduce pollutants as per CPCB recommendations. To achieve this, they required an accurate air quality monitoring system.Â
Oizom offered Polludrone Smart to the Adani Thermal Power plant unit in the Tiroda to monitor the dust and toxic gasses emitting from the plant to the surrounding city. Polludrone also comes equipped with data analyzing and visualization software that can keep track of the historical data and trends of the air pollutants emitted from the steel plants. Moreover, the polludrone can generate a report, which helps send reports in a timely manner to authorities like the State Pollution Control Board; further from SPCB, the data is pushed to the Central Pollution Control Board.Â
Oizom’s environmental monitoring devices used modern data loggers to collect and transmit essential data to the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCB). These data recorders are critical for correctly recording air quality and other environmental indicators, assuring regulatory compliance. Integrating Oizom’s technology with the CPCB and SPCB platforms allows real-time data access, resulting in fast and effective environmental management decisions. This facilitated data transfer not only aids monitoring efforts but also improves the accuracy of pollution control methods, resulting in a healthier environment.
