A REVIEW PAPER ON AIR POLLUTION AND CONTROL TECHNOLOGIES IN MECHANICAL ENGINEERING FIELD

Air pollution control is an important application of mechanical engineering. The reviewed research shows that diesel particulate filters, open-channel filters, adsorbent materials, and industrial baghouse filters can help reduce particular pollutants under suitable conditions.   CFD provides an additional engineering tool for improving airflow distribution and pollution-control equipment design. However, the performance of each technology depends on its operating conditions, material properties, maintenance requirements, and pollutant type.   Therefore, effective air-pollution management requires a combination of efficient combustion, appropriate exhaust treatment, industrial filtration, numerical simulation, and experimental validation. Further research should focus on improving efficiency, reducing operating costs, and developing sustainable pollution-control systems.
