Abstract

The invention relates to an electrochemical process and an electrochemical reactor system for cleaning of water, in particular groundwater, contaminated by organic or inorganic substances, such as chlorinated organic substances, aromatic-and aliphatic hydrocarbons and MTBE, wherein an alternating current (AC) is utilised to prevent deposition of insoluble compounds on the electrodes.
