<p>A process for treating, in particular cleaning, surfaces, in particular foils and metallic surfaces, is disclosed. Such surfaces are in general covered with a film of oil or grease immediately after they are produced. Grease and oil must however be removed before the surfaces or foils can be further processed, in order to ensure a perfect coating or gluing. In order to achieve this aim in a short time and with low energy consumption, a dielectrically blocked discharge (12, 2, 3, 13a) acts on the surface of the foil web (10), for example. The action of high-energy loaded particles and of photons from the UV spectral domain removes the film of oil or grease in a short time already, so that further processing (coating or gluing) is possible without causing an increased energy consumption nor damaging the surface. Disinfection/sterilisation are also considered as surface cleaning processes.</p> |
