Abstract
A composition and method for the bactericidal treatment of water with oligodynamic metal ions. The composition comprises a particulate silver yielding material and a particulate filler material which is intermixed with the silver yielding material. The silver yielding material comprises a highly porous carrier having a hardness which is greater than that of elemental silver and a layer of elemental silver on the surfaces of the carrier, and the filler material comprises a material, such as charcoal, having a hardness which is less than that of elemental silver. The composition is utilized in accordance with the method of the invention by passing a stream of water through a quantity of the composition to cause the particles of silver yielding material to mechanically interact with each other to release silver into the water. The particles of filler material, intermixed with the silver yielding material, buffer this mechanical interaction to provide a relatively slow release of silver from the composition which can be effectively controlled so that the composition and method can be effectively used in substantially closed systems, such as swimming pool systems.
