The invention relates to a device (10) for treating a liquid with a plasma, the device (10) having a high-voltage electrode (20) and a liquid-permeable ground electrode device (30). The ground electrode device (30) has a flat, conductive area (32) and a porous area (34) arranged on the flat, conductive area (32), the conductive area (32) being liquid-permeable along its area. A discharge space (40) is formed between the ground electrode device (30) and the high-voltage electrode (20).

The invention relates to a device (10) for generating a plasma jet (P) comprising a first conduit (11) inside a second conduit (12), a first electrode (17) and a second electrode (18) for generating an electric field in a feed gas flow (F) provided in a first flow channel (15) to generate a plasma jet (P), and adapted to provide a curtain gas flow (C) in the space between the first and second conduit (11,12), wherein the first electrode (17) is positioned radially outside of the first flow channel (15), and wherein the radial distance of the second electrode (18) from a longitudinal axis (l
