Abstract: A multi-barrier system for cleaning waste water, in particular for the removal of pathogenic microbes from waste water, and a method for the removal of pathogenic microbes from waste water with the multi-barrier system. The multi-barrier system includes an enclosed containment that comprises a first water container, an adjustable ozonation unit, a second water container and a UV unit. In addition, the first water container comprises an ozone-resistant filtration unit.

Abstract: A method of obtaining industrial water or drinking water from water that contains radioactive nuclides, in radium-containing groundwater including chemically pretreating the radioactive nuclide-containing water, and filtering the chemically pretreated water, wherein, in the chemical pretreatment, manganese dioxide is added to the water and/or manganese dioxide is generated in situ in the water and wherein filtration of the chemically pretreated water proceeds using at least one ceramic filter membrane.

Abstract: A filter unit for treating water includes at least two ceramic filter membranes; and a mount for the at least two ceramic filter membranes, wherein the ceramic filter membranes are formed in the shape of plates and each have a filter-active outer side and at least one internally lying discharge channel for filtered water, the mount has a collection space, via which water leaving the discharge channels can be drained, and the mount has at least two sockets that liquid-tight fix the at least two ceramic filter membranes in which they are fixed so that the internally lying discharge channels are in communicating connection with the collection space and at least the part of the mount having the sockets for the ceramic filter membranes is a shaped part formed in one piece.
