Patent ID: 6860990

Claim:
A device for anti-bacterial treatment, in particular decontamination and/or sterilisation of water and for killing micro-organisms in water, comprising a container formed to hold a water quantity intended to be treated, an electrode arrangement which acts on the water quantity in the container and is connected and operated with an electrical signal generating device provided outside the container, wherein the electrical signal generating device is operated with low voltage and is designed to generate an electrical alternating signal between electrodes of the electrode arrangement with a maximum amplitude <50 V and a signal frequency in the range between 1 and 5000 kHz, the signal generating device includes adjustment means which are designed for automatically changing a maximum amplitude, an amplitude stroke and/or a signal to pause ratio of the alternating signal as a function of a conductance value of the water quantity, wherein the container and the signal generating device form a portable unit and the electrode arrangement comprises at least one of (1) an at least partly longitudinally elongated wire shaped conductor as an electrode and (2) an electrode configured as a wire shaped pattern on a wall of the container.
