CATHODE, ELECTROCHEMICAL CELL AND ITS USE

摘要

The present invention relates to an electrochemical cell containing a sacrificial electrode suitable for electrocoagulation as well as an electrocoagulation process for removing various pollutants from water or wastewater by the use of the electrochemical cell. The present invention also concerns the sacrificial electrode per se. Several electrochemical cells according to the invention can be coupled to an electrochemical cell assembly. Certain aspects and embodiments of the invention are especially suitable for reduction of fluoride or fluoride in combination with heavy metals such as hexavalent chromium or arsenic.
