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.
L'invention concerne un procédé de purification de l'eau afin de la rendre potable. L'eau est d'abord passée dans une résine halogénée, puis dans un charbon actif imprégné d'argent dont la teneur est relativement élevée, d'au moins 2 % en poids et allant jusqu'à 14 % en poids. Le système de purification pour réaliser ce procédé consiste à appliquer, par ordre, une couche de résine halogénée, puis du charbon actif imprégné d'au moins 2 % en poids d'argent. L'argent imprégné absorbe efficacement un pourcentage important de bromure/brome, iodure/iode ou des mélanges de ceux-ci.
