APPARATUS AND METHOD FOR REMOVAL OF IONS

摘要

An apparatus and a method for removal of ions from water is provided. The apparatus is provided with at least three electrodes: two master electrodes (21, 22), each comprising a current collector connected to a power supply PC for creating an electrical potential difference between two master electrodes and at least one floating electrode (23) located between the two master electrodes. The apparatus is constructed to provide a potential difference between two master electrodes and to allow water comprising ions to flow from the water inlet (32) to the water outlet (33) between two adjacent electrodes. The ions in the water being attracted to the master and floating electrodes by the potential difference and the at least one floating electrode comprises an ion barrier layer (73). An insulating material (83) extends outwardly from the electrode (23) in a longitudinal direction.
