De Nora’s roots in the chlorine and chlorate industries run deep. From the creation of the earliest commercial diaphragm cells in the early 1900s, to the development of the very first membrane cell and now the most competitive anode coatings available. The introduction of DSA^® in mercury cells was justified primarily by the benefit of power savings and the elimination of some hazardous plant operations associated with the use of graphite anodes, increased production, and product quality. 

De Nora efforts are aimed at radically improving the economics of the Chlor-Alkali business studying components like Gas Diffusion Electrodes that are going to be the feature of choice for the future generation of high CD IEM. We offer recoating techniques for almost any IEM cell type. We have developed cathode coatings suitable for all technologies and reduce cell voltage.

De Nora can provide: 

• DSA^® anodes, the most successful and economical electrode for the production of chlorine and caustic soda by MEMBRANE/AMALGAM/DIAPHRAGM technologies. 

• Anodes for different types of mercury cells under a lease or purchase program. 

• Services for the anode structures include repair work and renewal of the DSA^® coating with the recoating of deactivated electrodes including the necessary mechanical repairs to the structures. 

• Technical Assistance to train and support customers in the installation, use and operation of cells and anodes. 

• Diaphragm that eliminate the need for asbestos, cell tops that last decade or more,  and everyday spare parts to keep existing plants running like new.
