Claims9
A bioactive filter for disinfection of liquids, for water or aqueous solutions in containers, comprising:
- a spherical or oval filter body coated with noble metals,
- wherein the filter body includes two hemispherical filter parts made of stainless steel wire mesh, which are connected to one another by a ring made of stainless steel,
- wherein each of the filter parts has, on its open side, an outwardly projecting collar,
- wherein the outwardly projecting collar consists of the wire mesh,
- wherein the ring connects the two collars to one another,
- wherein at least one of the wire mesh or the ring is coated with silver and then with ruthenium or bimetallic particles that consist of silver and ruthenium, and
- wherein the ring is pressed, crimped, stamped, riveted, or welded onto the collars.
