Abstract (en)
[origin: WO9429228A1] A process for the purification of water to render it fit for drinking. It is passed first through a halogenated resin and after this through activated carbon impregnated with silver, which contains a comparatively high silver content, of at least two per cent by weight, and up to about 14 weight per cent. A purification system for carrying out such process comprising a sequence of a layer of halogenated resin followed by activated carbon impregnated with at least two weight per cent silver. The impregnated silver absorbs efficiently a high percentage of bromide/bromine, iodide/iodine or mixtures of these.
