Simultaneous removal of fine particles and gaseous pollutants using catalyst-coated fabric filter and discharge plasma

Summary form only given, as follows. The purpose of this study is to investigate the feasibility of simultaneous removal of fine particles and VOCs using a combined system of photocatalyst-coated nonwoven fabric filter and discharge plasma. In this study, the NaCl aerosol was selected as a test aerosol, and generated by nebulizing 10%-20% aqueous NaCl solutions using air bubbling system. Acetaldehyde (CH/sub 3/CHO) vapor was selected as a VOC. The test results indicate that TiO/sub 2/ catalyst coated on the surface of nonwoven fabric combined with discharge plasma has a potential for treating pollutants in the atmospheric environment.
