DSA® Anodes and Coatings

Over the last 18 years, pulp and paper manufacturing companies have converted to the use of environmentally friendly sodium chlorate for their pulp bleaching processes. This conversion has made the production of sodium chlorate a major chemical industry with production of over 2.3 million tons per year. Today more than 95% of the sodium chlorate produced is consumed in pulp bleaching.

INDUSTRIE De NORA is the leading supplier of anodes and anode coatings for the production of sodium chlorate in all technologies:

• Industrie De Nora coatings are able to operate at a very high current density (up to 6 kA/sq M), long life (more than 8 Years in many cases and high efficiency.
• Industrie De Nora coatings are low oxygen for improved efficiency and designed to reduce the impurity build-up typical of conventional coatings used in sodium chlorate production.
• Industrie De Nora continues to develop new anode coatings to further increase production efficiencies, reduce by-product oxygen and reduce overall costs.
• Industrie De Nora's supply management group is expert in the acquisition of long lead item materials such as titanium.
• Industrie De Nora has also commenced development work on a cathode coating for use in chlorate cells to reduce power costs.
