icroorganisms; activated carbon adsorbs VOCs but saturates quickly; and UV-C irradiation kills microbes but does not remove chemical pollutants. This study proposes a hybrid air filtration system inspired by Moving Bed Biofilm Reactor (MBBR) technology. The system integrates four sequential stages: (1) HEPA pre-filtration to remove particulate matter, (2) activated carbon adsorption for VOCs, (3) a mobile biofilm chamber with non-pathogenic microbial carriers to biologically degrade VOCs, and (4) UV-C irradiation for microbial inactivation. The hybrid approach combines mechanical, chemical, biological, and photonic purification, enhancing multi-pollutant removal, energy efficiency, and system sustainability. A laboratory-scale prototype is constructed and tested under controlled environmental conditions. Microbial aerosols and VOC concentrations are monitored at mu.. Read More»
