Dielectric barrier discharge system and method for decomposing hazardous compounds in fluids

A dielectric barrier discharge system for generating one or more reactions in one or more compounds within a fluid, the system comprising:

• a first non-thermal plasma reactor comprising a first fluid inlet, a first fluid outlet, a solid compound outlet, a first flow path from the first fluid inlet to the first fluid outlet and a first surface discharge electrode which comprises first and second oppositely polarized conductors, which are spaced from one another laterally along a first discharge surface that is parallel and adjacent to the first flow path, and defines a first surface discharge path between the first and second conductors along the first discharge surface, wherein the solid compound outlet is positioned relative to the first flow path and the first discharge surface to receive solid compounds removed from the fluid within the first flow path;
• and
• a second non-thermal plasma reactor coupled in series with the first non-thermal plasma reactor and comprising a second fluid inlet, a second fluid outlet, a second flow path from the second fluid inlet to the second fluid outlet, and second and third oppositely polarized volume discharge electrodes, which are parallel to one another and are separated by a gap that extends across the second flow path and defines a second discharge path between the second and third volume discharge electrodes.
