Efficacy and Efficiency of an Atmospheric Pressure Dielectric Barrier Discharge Reactor (GAPS) for Air Disinfection

2026

Abstract

Airborne transmission of pathogens has emerged as a critical challenge in indoor environments, prompting the development of advanced air‐sanitization technologies. Among these, nonthermal plasma has shown promising antimicrobial effects. In this study, we evaluated the biological efficacy and energy efficiency per order (EEO) of the Grid‐like Air Plasma Sanitiser (GAPS) reactor. Experiments were conducted with Escherichia coli MG1655 bioaerosols. The GAPS achieved a reduction up to in a single pass, confirming its strong bactericidal effect. The corresponding EEO was , highlighting the reactor competitive efficiency compared with conventional methods. Preliminary assays with SARS‐CoV‐2 bioaerosols were carried out too showing a reduction of , further supporting the reactor's potential for viral inactivation.

Generation IV reactor

Generation IV reactors (Gen IV) are nuclear reactor design technologies that are envisioned as successors of generation III reactors. The Generation IV International Forum (GIF) - an international organization that coordinates the development of generation IV reactors - specifically selected six reactor technologies as candidates for generation IV reactors. The designs target improved safety, sustainability, efficiency, and cost.

Breeder reactor

A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. These reactors can be fuelled with more commonly available isotopes of uranium and thorium, such as uranium-238 or thorium-232, as opposed to the rare uranium-235 which is used in conventional reactors. These materials are called fertile materials since they can be bred into fuel by these breeder reactors. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use.

Generation III reactor

Generation III reactors, or Gen III reactors, are a class of nuclear reactors designed to succeed Generation II reactors, incorporating evolutionary improvements in design. These include improved fuel technology, higher thermal efficiency, significantly enhanced safety systems (including passive nuclear safety), and standardized designs intended to reduce maintenance and capital costs. They are promoted by the Generation IV International Forum (GIF).
