Abstract

An apparatus for corrosion protection of a water system is disclosed, where a hitherto unknown principle for the production of ions of alkaline sensitive metal is used. The apparatus comprises a container (1,14,17), fully or partly flown through by the water, connected as cathode and/or comprising at least one cathode (9,10), the apparatus being provided with at least one anode (3), wherein cathode and anode are connected to a DC source, characterized in that at least one electrode (4), comprising alkaline sensitive metal and electrically isolated from the cathode and the anode connected with the DC source, is provided such that at least a part of the electrical current running through the water from the anode to the cathode, is forced through the electrode comprising alkaline sensitive metal. <IMAGE>
