摘要

Device for purification of water (2) in a container (1) using oligodynamic effect, comprises a silver compound as active ingredient, which is enclosed in a water-permeable protective sheath (3) and the protective sheath with an active substance in the water is placed in a container. The active substance is coated with a fine-grained carrier material (4) as a coating. The grain size of the carrier material is less than 10 mu m and the protective sheath surrounding the coated carrier material has pores or mesh sizes, which is less than 5 mu m.
