ABSTRACT
Corrosion occurs constantly in every water/wastewater treatment plant, as well as throughout the pipe line system. There are many different types of corrosion that occur. The corrosion are of two general types—galvanic and chemical. While the galvanic cell has been used to describe the ion exchange process that takes place when different kinds of metals are used, a single piece of metal is a galvanic cell by itself. Basics of corrosion make it easier to take the necessary corrective action to control corrosion and extend equipment service life. Controlling corrosion through the use of galvanizing structural parts is not commonly done in water/wastewater treatment plants. However, even though this is more of an initial treatment when the building is being constructed, it can be applied to specific components or additions to the plant. In order to be totally effective, the components must be completely submerged in hot zinc.
