Corrosion is a never ending battle in the water treatment industry. It is an electrochemical process in which a difference in electrical potential develops between two metals or between differeing parts of a single metal. Electrons flow from the anode to the cathode. Metal ions go into solution at the anode causing metal loss (corrosion). The speed at which the ions go into solution can be increased with higher conductivity waters (sea water, cooling water, boiler water). There are many types of corrosion and many more ways to control it. Having a basic understanding of the process will enable you to better choose a treatment option best suited for the application.
