Abstract

Method for cleaning and disinfecting treatment of water, during which the water is exposed to at least one electric field, whereby the electric field is a low-current field with pulsating direct voltage. Device for realization of the method which includes a source of pulsating direct voltage; two conducting elements, which are connected in a conducting manner to the source of pulsating direct voltage and which are arranged to achieve a low-current field with pulsating direct voltage between them; together with a device for changing in a time-dependent manner the direction of direct voltage. Device for realization of the method which includes a source of a rectified pulsating magnetic field and a conducting element, which is arranged in the pulsating magnetic field such that, during operation of the device, an electric field is produced around the conducting element by electromagnetic induction.
