PolyPhosphates All Sterling Water Technologies PolyPhosphates are certified to ANSI/NSF Standard 60 for use in potable water. Unlike orthophosphate based chemistries, polyphosphates (metaphosphates) will sequester cations in solution such as iron and manganese. By sequestering these and other problematic cations in the treated water, water can remain clear and colorless thus reducing customer complaints. While these cations are not actually removed in the process, the polyphosphate is able to interrupt the crystal or precipitate forming process of these cations which typically result in the complaints received. By preventing the conversion of these cations from a soluble to insoluble form, the resultant red or black water is not formed. As polyphosphates revert to orthophosphate over time in the distribution system, additional corrosion protection is achieved through a dual action process. Polyphosphates have been known to act as cathodic inhibitors further reducing corrosion tendencies. Polyphosphates also act to reduce scale and tuberculation formation in the distribution system. By again interfering with the crystallizing formation, polyphosphates can reduce existing scale formations as well as prevent future formation. By preventing scale formation, taste and odor issues, higher pumping costs and pitting type corrosion can be eliminated. Services On-Site Consultation PolyPhosphates - Applications
