High Performance


Long Life

De Nora DSA® anodes are efficiently and widely used worldwide in brine or sea water electrolysis, for chlor-alkali production, primary metals refining and many other electrochemical processes in which chlorine evolution represents the key anodic reaction.
De Nora was the first company to commercially develop mixed metal oxide (MMO) - coated metal anodes back in 1968, progressively replacing the less performing graphite anodes, revolutionizing the way of producing chlorine and its technologies become the benchmark for the chlor-alkali industry.
