Orthophosphate is an anodic corrosion inhibitor that is commonly used in potable water systems. It effectively inhibits corrosion of carbon steel, lead, and copper. It is often used to reduce lead solubility by the formation of a lead orthophosphate film. This allows for less lead contamination and reduces maximum contaminant levels (MCL’s) for regulatory requirements. Orthophosphate eliminates or minimizes red water deposit formation and works in combination with other inhibitors.
