1. Container, protected from internal corrosion, comprising layers of differing conductivity in the contents of the container, particularly a filter container, characterized in that one or more inert anodes (A), supplied by parasitic current, are situated in the container (B), these anodes having longitudinal sections (E, F, G) of differing electrical surface conductivity and the electrical surface resistance of any longitudinal section being the higher, the greater the electrical conductivity of the contents of the container, associated with that longitudinal section. |
