HL Series Water Softening NF Elements

The H-Series proprietary thin-film nanofiltration membrane elements are characterized by an approximate molecular weight cut-off of 150-300 daltons for uncharged organic molecules. Divalent and multivalent ion rejection is dependent upon feed concentration and composition.

HL Nanofiltration Elements are used for water softening, color removal, and reduction of THM potential.

Note

Average salt rejection after 24 hours operation. Individual flow rate may vary +25%/-15%.
Testing conditions: 2,000ppm MgSO4 solution at 100psig (690 kPa) operating pressure, 77°F, pH7.5 and 15% recovery.

Note

This product ships dry.
