Abstract: The invention relates to methods and devices for the decontamination of fluid, particularly the removal of heavy metals and/or arsenic and/or their compounds from water, by means of electrolysis, wherein the water to be purified subjected to electrodes of different polarities. The invention can include means for control of the pH of the fluid. The invention can also include control systems that allow self-cleaning of electrodes, self-cleaning of filters, and automatic monitoring of maintenance conditions.

Abstract: The invention relates to a device for the decontamination of water, particularly of heavy metals and/or arsenic and/or their compounds, by means of electrolysis, wherein the water to be purified is fed through a receptacle and passes by electrodes of different polarities. According to the invention, a combination of electrodes made from iron, aluminium, and graphite, or from aluminium and graphite, is used. Facing the direction of the receptacle bottom, the undersides of the electrodes are contained in groove-like, electrically insulated recesses that are spaced apart and separated from one another on their opposite side by single electrically insulating spacers, wherein the spacers are attached to the electrodes, and the electrodes, which can be unfolded, are arranged in the groove-like recesses (FIG. 5).
