3.3: Slow Dissolve Polyphosphate Cartridges

Polyphosphate media helps prevent lime and scale deposits from water and is effective for treating corrosion and iron problems. The slow dissolving beads dissolve at a controlled concentration to inhibit scale formation and corrosion. A concentration level of 0.5 ppm to 5.0 ppm polyphosphate is typical for scale and corrosion treatment.


  • Compact, easy to use polyphosphate cartridges

  • Slow dissolving polyphosphate media in small glassy beads
  • Fits standard size and large diameter size housings


  • Potable drinking water systems
  • Water coolers, coffee machines, and ice machines
  • Cooling and refrigeration equipment
  • Pre-treatment and post-treatment filter on a multi-stage configuration
  • Residential, commercial, and industrial applications

Materials of Construction:

  • Filter Media: Polyphosphate spheres
  • Outer Shell and End Caps: Polypropylene
  • Post-Filter & Expansion Pads: Polypropylene
  • Gaskets: Nitrile
