Polyphosphates
Sequestering Agents
Polyphosphatess are sequestering agents that remove “red water” from source supplies as well as stabilize iron, manganese, and calcium in potable water systems. Polyphosphates are multipurpose in application as they stabilize water systems to minimize or prevent scale and iron deposits in system piping where pre-existing deposits occur. Polyphosphates act to slowly remove these restrictions and help restore hydrolic efficiency to the system. Stains and discolorations from corrosion products are equally removed along with improving the aesthetics of the systems.
