ABSTRACT:
The present invention relates to a method for the demineralization of water using a combination of a monodisperse cation filter operated as a lift bed and a monodisperse anion filter operated in the cocurrent flow procedure, and also devices which comprise such a lift bed in combination with at least one cocurrent flow filter and if appropriate a trickling degasser and/or a mixed-bed filter.
