Abstract

The disclosure relates to a plasma activated fluid processing; including an alternating current, AC, source, one reaction chamber, wherein the one reaction chamber has a plurality of reaction electrodes and a corresponding ground electrode, each reaction electrode and corresponding ground electrode separated by a gap; or a plurality of reaction chambers, wherein each reaction chamber has at least one reaction electrode and a corresponding ground electrode, the reaction electrode and corresponding ground electrode separated by a gap; wherein the AC source is electrically connected on one side to each ground electrode in parallel and on another side to each reaction electrode in parallel, wherein each reaction electrode is connected to ground via a capacitor, and wherein an inductor is provided between each reaction electrode and the AC source.

Claims (18)
