Dielectric Barrier Discharge

A dielectric barrier discharge is a dry method of plasma treatment that doesn't generate wastewater or require drying of the material after treatment.

This technology is used in fuel production, gas scrubbing to reduce harmful emissions, and bulk surface activation for large surface areas or continuous processes.

Plasma is produced by two electrodes with a dielectric between these electrodes to limit the current flow in the plasma. This low-density plasma can be described as Dielectric Barrier Discharge (DBD). 

This method of plasma production is also called silent discharge due to the current limiting dielectric controlling the rate of ionization of the gas.  This relatively low-density plasma produces controlled ionization of the available gas generating little to no detectable sound.  This method of low-level density plasma production is useful in gas plasma processing like ozone generation, gas reforming, and broad area low-level activation processes.
