Abstract: A device for condensing water includes a container with a plurality of openings and a heat transfer zone arranged in an interior of the container. The heat transfer zone includes a bulk material layer and/or a fiber layer and/or a textile layer and/or a grid layer and/or a lattice layer and/or a perforated plate. The interior of the container is subdivided by the heat transfer zone into a first zone and a second zone. Further, the heat transfer zone has at least in sections an open porosity and/or channels through which process gas can flow from the first zone to the second zone and through which a further process gas in the form of cooling gas can flow in a reverse direction. A permeable region of the heat transfer zone partially includes materials which have a thermal conductivity of more than 20 W(mK)?1 in a temperature range up to 300° C.

Abstract: A device (100) for breaking down pollutants in a liquid (F) by oxidative OH radicals has an arrangement of positively and negatively charged electrodes (104a . . . 104n, 105a . . . 105n), wherein at least one of the positively or negatively charged electrodes (104a . . . 104n, 105a . . . 105n) is surrounded by a separator (107) at least in the contact zone between the liquid (F) and the electrode (104a . . . 104n, 105a . . . 105n).
