Water Quality

Orthophosphate in Drinking Water | Orthophosphate Water Orthophosphate In Drinking Water | HydrovivOrthophosphate is a common corrosion inhibitor used by water suppliers to prevent lead pipes from leaching. When orthophosphate water treatment is added to a water source, it reacts with lead to create a mineral-like crust inside of the lead pipe. This crust acts as a coating which prevents further lead corrosion.Orthophosphate - an overview | ScienceDirect TopicsM. Miró, W. Frenzel, in Encyclopedia of Analytical Science (Second Edition), 2005 Phosphorus and Silicon Compounds.
