ABSTRACT:
A device for anti-bacterial treatment in particular decontamination and/or sterilisation of water and for killing micro-organisms in water, with a container designed to hold a water quantity intended to be treated and an electrode arrangement which is designed to act on the water quantity in the container and which can be connected and operated with an electrical signal generating device provided outside the container, where the electrical signal generating device can be operated low voltage and is intended 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, in particular 5 to 50 kHz, where the signal generating device has an adjustment device designed for automatic changing of a maximum amplitude, an amplitude stroke and/or a signal/pause ratio of the alternating signal as a function of conductance value of the water quantity.
