Abstract
The present invention relates to the treatment of wastewater by electrochemical reactions. More particularly, an Electro-Reaction Unit (ERU) is disclosed. The ERU is provided with at least one electrolytic cell comprising a pair of self-cleaned electrodes for purifying wastewater. Along with electro-reactions, electrodes of the ERU are submitted to passivation, i.e. coverage with an oxide layer. The present invention provides a solution for alleviating passivation with a self-cleaning system comprising hard elements, confined in a cage and movable therein, for bombardment of the electrodes and rupture of the oxide layer. The present invention further provides a related process.
