Abstract

A treatment system or treatment reactor (1) comprising at least one dielectric barrier discharge lamp (2) with a first electrode (20) and a housing (10) for containing a medium (3) like a fluid and/or a gas and/or a solid material which is to be treated by means of the radiation generated by the lamp (2) is disclosed which is especially characterized in that at least one second electrode of at least one lamp (2) is provided in the form of at least one intermediate counter electrode (3, 4) which is positioned within a volume (31) between at least one dielectric barrier discharge lamp (2) and the housing (10). By this, influences of the treated medium on the electrical behavior of the treatment system or reactor (1) and especially power losses in the medium can be avoided or considerably be decreased. Furthermore, losses of the lamp light due to absorption and/or shadowing at an outer electrode surrounding the lamp are avoided as well.
