Standard 20"x 2.5" Nitrate Removal Filter Cartridge. Contains special nitrate-selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sulfate levels. Will fit standard housings that use 20x2.5 inch filters.

Optimum performance is achieved at 0.5 GPM (gallon per minute). Be aware, that the higher the flow rate, the less nitrates will be removed from water. The cartridge capacity is 22700 ppm of nitrates as NO3. This cartridge can be regenerated using sodium chloride brine.

About Filtration Media

Media in this cartridge is a strong base anion exchange resin supplied in the chloride form as moist, tough, uniform spherical beads. It is especially useful in nitrate removal applications due to its ability to remove nitrates in the presence of sulfates and other divalent ions.

It is also intendend for use in application involving monovalent and divalent ions where monovalent ions must be removed preferentially, such as removing perchlorates from ground water

  • The resin has Highest Operating Capacity of Any Nitrate Selective Resin
  • Low Pressure drop while maintaining superior kinetics
  • Manufactured in USA
