Anodes for Chlorine Evolution

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. 

Why chose DSA® anodes for chlorine evolution? 

De Nora was the first company to commercially develop mixed metal oxide (MMO) - coated metal anodes back in 1968, progressively replacing the under-performing graphite anodes. This technology revolutionized the process of producing chlorine and this technology became the benchmark for the chlor-alkali industry. 

Over the years, through innovation and continual improvement, catalysts and manufacturing process of our anodes have been optimized, ensuring our customers benefit from higher production efficiency and minimizing production costs. 

Today, we can offer a wide portfolio of long-lasting dimensionally stable anodes, with extremely low chlorine evolution overvoltage, high selectivity and a remarkable effectiveness in energy savings, providing stable operation, minimum plants downtime and product quality.
