Felite™ FS500 is a potable water grade, macroporous strong base anion resin which is specially designed for the removal of nitrates from raw water. The macroporous matrix and special ion exchange group functionality imparts ideal nitrate selectivity to Felite™ FS500 making this resin particularly suitable for nitrate removal even when moderate to high concentrations of sulfate are present.

Felite™ FS500 is intended for all nitrate removal applications, and can also be used to remove perchlorate.
