Design and Fabrication of Small-Scale Urban Air Purification Tower

Air pollution has become a significant environmental issue in the twenty-first century, causing negative impact on quality of life and human health. Various international organizations have been working to address air issues provide potential solutions. One primary tools used measure is Quality Index (AQI), which ranges from 0 500, indicating levels different pollutants ambient air. Particulate matter (PM) one most hazardous pollutants. Outdoor purification towers are promising technology issues, this project aims design fabricate an tower for Karachi, biggest city Pakistan industrial hub with issues. The lack devices throughout country motivation behind project, main objectives include observing current situation testing performance tower, evaluating feasibility be replicated larger scale. project’s methodology includes review existing literature engineering knowledge, followed by calculations based heat losses, velocities, volume flow rates. A parametric study economic analysis were select feasible dimensions, CAD model was developed. report outlines chronology, including introduction, review, assessment loss coefficient, velocity rate calculations, reach optimal dimensions fabrication. significance lies addressing providing solution Karachi’s problems. success could inspire further replication scale other countries facing similar
