Polyphosphates have many uses in the treatment of potable (drinking) water. They are used to prevent “red” (from iron) and “black” (from manganese) water; to prevent and/or retard scale formation (from minerals depositing) and corrosion (from low pH and/or dissimilar metals) in the water distribution system; and to reduce soluble lead and copper in potable water delivered to the consumer’s tap. Using their properties of Sequestration, threshold ability , Deflocculation, Chlorine Stability , and Hydrolytic Stability they are widely regarded as a safe and effective treatment for potable water
