Title (EN) USE OF AN ANODE FOR ELIMINATION OR REDUCTION OF MICROBIAL IMPURITIES IN LIQUIDS
(FR) UTILISATION D'UNE ANODE POUR L'ELIMINATION OU LA REDUCTION D'IMPURETES MICROBIENNES DANS DES LIQUIDES
Abstract:
(EN) The present invention relates to the use of an anode suitable for use in inter alia a reactor for elimination or reduction of microbial impurities from liquids, such as inter alia waste water and water intended for human or animal consumption. The anode comprises an expanded metal plate, preferably titanium, covered with a non-corrosive metal layer, preferably a platinum layer. The surface of the anode is endowed with dents, which enhances the electrochemical effect between the anode and the corresponding cathode and thereby enhances the microbial effect and at the same time reduces the energy required to obtain an efficient kill of the microorganisms.
(FR) La présente invention concerne l'utilisation d'une anode pouvant être utilisée, entre autres, dans un réacteur pour l'élimination ou la réduction d'impuretés microbiennes à partir de liquides, tels que, entre autres, des eaux usées et de l'eau destinée à la consommation humaine ou animale. Cette anode comprend une plaque d'un métal expansé, de préférence de titane, recouverte d'une couche d'un métal non corrosif, de préférence d'une couche de platine. La surface de l'anode comporte des indentations, ce qui contribue à renforcer l'effet électrochimique entre l'anode et la cathode correspondante, d'où un renforcement de l'effet biocide et, concomitamment, une réduction de l'énergie requise pour obtenir une mise à mort efficace des micro-organismes.
