The 3M™ Aqua-Pure™ AP430SS Scale Inhibition System:
How it Works
Polyphosphates in minute concentrations of 2-3 ppm, effectively help prevent scale buildup by inhibiting the deposition of hardness minerals onto metallic surfaces. Polyphosphates also help prevent corrosion by forming a thin protective layer on the metal surface. The 3M Aqua-Pure Scale inhibition is manufactured using FDA CFR-21 compliant materials*.
