Comparison of direct DBD treatment and DBD exhaust gas treatment of liquids

摘要

The treatment of liquid with a surface dielectric barrier discharge (DBD) under atmospheric pressure in air results in pH decrease and generation of nitrate (NO3⁻), nitrite (NO2⁻) and hydrogen peroxide (H2O2) in water. Even, after plasma treatment antimicrobial effects on suspended microorganisms were investigated [1] [2].
