Abstract

This research studied the development of a PM2.5 air filtration tower using a hybrid technique (hybrid wet scrubber tower) along with an IoT-based monitoring and control system. The experimental research methodology involved three main steps: firstly, designing and developing a hybrid wet scrubber tower that combines spray scrubber and turbulent water scrubber techniques; secondly, developing an IoT-based monitoring and control system that includes sensors to measure various parameters such as air flow rate, water flow rate, pH level, PM2.5 concentration, and temperature-humidity; and lastly, testing the performance of
the hybrid wet scrubber tower under controlled conditions in a test chamber. The study found that the developed hybrid wet scrubber tower could capture more than 80 percent of PM2.5 particles, and the tower's operation could be monitored and controlled using integrated IoT system. It was noticeable that the proposed hybrid wet scrubber tower was suitable for installation in semi-enclosed areas such as public transportation stations, bus stops, and parking buildings.
