Abstract: Presently disclosed subject matter relates to application of dielectric barrier discharge in misty plasma systems for disinfection of surfaces and equipment in health settings. A system and corresponding and/or associated methodology is provided for planar dielectric barrier discharge (DBD) device technology. Per one exemplary embodiment, a DBD device is provided with an electrically insulated annular flow channel built through the planar powered electrode. The discharge medium is air saturated with water vapor that flows through the annulus and forms a stagnation discharge plane between the powered dielectric and the substrate. Application on Escherichia (E.) coli and Bacillus (B.) atrophaeus spores on agar and filter papers show that usage of a flowing humid discharge medium has a ˜40% higher efficacy than either a static or a dry flowing medium. The substrate turns acidic potentially due to the formation of reactive oxygen and nitrogen species.

Abstract: A dielectric barrier discharge system, employed to reform/remove organosilicon contaminants off a carrier stream to provide a sustainable, end-of-technology way of siloxane removal that will ensure siloxane does not re-enter the carrier stream, as well as generates useful end-products.
