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.
Claims8
A method for the demineralization of water using ion-exchanger filters, which comprises using a combination of a cation filter comprising monodisperse strongly acidic cation exchanger and operated as a multichamber lift bed and also at least one anion filter comprising monodisperse strongly basic anion exchanger and operated in cocurrent flow.
A device for the demineralization of water comprising
- a) a multi-chamber lift bed, wherein said multi-chamber lift bed comprises monodisperse strongly acidic cation exchanger;
- and
- b) a cocurrent flow filter, wherein said cocurrent flow filter comprises at least one anion filter, said anion filter comprises a monodisperse strongly basic anion exchanger.
