Abstract

L'invention concerne un dispositif de purification de l'eau (104) pour la purification de l'eau. Le dispositif de purification de l'eau (104) comprend une unité de désinfectant primaire (116) et une unité de désinfectant secondaire (118). L'unité de désinfectant primaire (116) comprend au moins un matériau poreux traité avec de l'argent (302) configuré pour inactiver une première partie des contaminants microbiens présents dans l'eau. Une seconde partie des contaminants microbiens présents dans l'eau est inactivée par l'unité de désinfectant secondaire (118) qui contient au moins un composant libérant un halogène (402).
