Recently atmospheric pressure dielectric barrier discharge (APDBD)
plays an important role in chemical, industrial and
biological applications. It has been used for ozone
synthesis, hydrogen production from natural gas, surface
treatment including textile and polymer treatment, yeast and
bacterial inactivation. The physics and mechanism of
atmospheric pressure dielectric barrier discharge will be
reviewed. Coaxial and planar DBD have been constructed for
ozone production, textile treatment and yeast sterilization.
Oxygen has been used as working gas for ozone production,
while oxygen and argon will be used for yeast inactivation.
Key words: Microdischarge, DBD, ozone, yeast sterilization. |
